The secret button is a modern development to protect your vehicle from theft. In case of hacking, the device installed in a certain place is triggered and blocks the start power unit, transmission and other components. When installing a “secret” anti-theft device on a car, you must follow certain rules, as well as safety precautions.

The principle of operation of the “secret”

When trying to start the engine, the car owner presses a button, then applies the magnetic key and enters the secret code. Or the power unit can be started by turning an additional key. If a criminal managed to hack the anti-theft system and the alarm siren does not work, he will have to spend time finding the button and deactivating it. Otherwise, he will not be able to start the engine, nor will he be able to steal the car.

Using the example of a branded secret lock, you will learn about the principle of operation of the device from the video filmed by the Axius-auto channel.

Let's look at the principle of operation using the example of a simple blocker:

1. After the car owner enters a password for protection, the following occurs.
2. If the criminal is able to get into the car and tries to start the engine, the power unit will begin to function, but will stall after a few minutes so that the criminal will not be able to get far from the crime scene.
3. If an attacker enters the password incorrectly several times, all systems will be completely blocked.
4. If the criminal tries to unlock the nodes and drive away in the car, the systems will emit sound signals, which should scare off an attacker.

Types of "secrets"

There are several types of blockers on sale; let’s look at each of them in detail.

By mechanism

According to the triggering mechanism, secret blockers are divided into mechanical and electronic.

Electronic

Electronic devices can be different:

• push-button systems designed to block the start of a car engine;
• motion controllers used to detect activity;
• stun guns, such devices shock a burglar if he tries to steal a car;
• devices with passwords and codes designed to disable secret button.

Roman Petrov in the video talked about programming a car “secret”.

Mechanical

Mechanical secret buttons are divided by purpose:

1. The button can be used to lock the wheels. This device is made in the form of a lock with a bolt and nut, has a unique design and a special key on which the fingerprint is located. It is used to open the lock.
2. Devices for installation on the steering wheel or door locks.
3. Locks to prevent locks from opening luggage compartment and hood.
4. Devices used for blocking exhaust pipe.

According to the operating principle

Blockers are also divided according to the operating principle:

1. With the sequence specified by the developer. Disabling is done by entering combinations with the button.
2. To protect the engine compartment lock.
3. Devices that enable activation and deactivation of a blocker using a password.
4. Disabling and enabling the device is possible by entering a password in a specific sequence for standard and additionally installed toggle switches.
5. It is possible to use a secret motion controller. It is activated when unauthorized entry into the car’s interior occurs and works by transmitting coordinates about the location of the car.
6. There are special motion controllers that block the engine during unauthorized start. They do not track the location of the car, but they also do not allow the criminal to move around in it.
7. Attachments belonging to the type of mechanical devices.
8. Special locks equipped with an additional siren.

On wheels

Secret buttons are conventionally divided into three types and differ in profile:

1. Made in the form of an asymmetrical polygon. These devices are considered among experts to be the simplest option in design. The number of edges can be different - from 8 to 40 pieces, their number is directly proportional to the degree of protection. The profile is installed on external and internal screws. It should be noted that blockers with 30 and 40 edges are available only with an internal profile.
2. Devices with a shaped profile. Such blockers are complex in design, but this type of blockers provides reliable protection for the wheels. The profile element itself is a collection of different curvatures of lines. If the key is missing, the burglar will not be able to remove the bolt and unlock the wheels.
3. Hole devices. In the head of such a screw there are holes that differ in depth and size. They can be arranged in a chaotic order.

On sale you can find blockers that are a combination of perforated and shaped devices. Such devices are as reliable as possible.

You will learn about the advisability of using secret wheel locks and how to remove them from the video published by the Theft channel. no - Anti-theft protection.

On the hood

A hood lock is a device used to prevent theft of major machine components located in engine compartment. Designed to protect the engine compartment from intruders. To the side of the locking device, opposite from the standard cable, it is installed additional blocker. At its other end, for example, in the glove box, there is a lock with a key. If the second device is closed, you will not be able to open the hood using the standard handle.

You will learn how the “secret” for the hood works from the video published by Leonid Kovalenok.

On the engine

Also called an immobilizer. This is a simple electronic device designed to prevent the power unit from starting. It is considered one of the most reliable types of devices designed to protect a car from theft, since bypassing IMMO is not so easy. The main advantage of the engine blocker is its secrecy; only the owner of the vehicle can unlock the power unit.

To provide hidden protection, any button in the car interior can be used; if necessary, an additional toggle switch is displayed. But this reduces the device’s secrecy. If you install a separate button, then it can be located anywhere in the vehicle. The main thing is that the car owner can reach it from the driver’s seat.

The principle of operation of such a blocker is to break the fuel supply circuit or block the starter device. The starter is unlocked and the circuits are restored if the driver enters a password or presses a button. If the code is entered incorrectly several times, the anti-theft device will be activated to operate in enhanced mode.

On the license plate

Number blockers are used specifically to protect numbers from theft. Based on the principle of operation, these devices are similar to “secrets” for wheels. Such devices are made in the form of screws, on the heads of which relief images are applied. To disable protection, you will need a key. It is unique and comes complete with a bolt; it is impossible to match it.

The blocker package includes:

• four screws;
• nuts;
• washers;
• special wrench for installation;
• key.

User Ruslan Yunyaev demonstrated in the video the procedure for installing a secret lock on a car number.

Squib

This option is the most radical. The cost of the squib is quite high, but its use can lead to negative consequences for the engine room. If a criminal tries to steal a car, a caustic gas device will be activated. Spraying it throughout the cabin will prevent the burglar from finishing his job. But the smell of the substance can remain for a long time.

How to install "secret"

Let's look at an example of installing a wheel lock. In the process of implementing this task, working bolts will be required; the use of elements from Zhiguli cars is allowed.

How to install an anti-theft security system on a car:

1. Using a blank, you need to make three holes; they should be symmetrical relative to each other. Each of them is carved.
2. Another hole of a larger diameter is made, it also needs to be threaded. Please note that this procedure is not so easy to complete, so experts recommend using the services of turners.
3. The screws are installed in the drilled holes; they must be pressed tightly against the frame.
4. To ensure sequential pressing of a button, you need to do electrical system. To implement this task you will need wireless relay, it can be bought on the radio market. It is allowed to use any type of “secret”, for example, Hock-Up.
5. The relay is installed on any section of the electrical circuit in a cut. Be sure to install it with a positive output; take into account the nuances of the location of the standard wiring. All electrical circuits from the device must be routed to the center console or anywhere in the cabin. You can use a hidden option, for example, in the glove compartment or on the side of the dashboard.
6. In accordance with the instructions included in the kit, the electronic component is installed. If problems arise at this stage, we recommend contacting an electrician.

Konstantin Skots in his video talked about the development and connection of a secret button in a car.

If you want to install an anti-theft blocker yourself, we recommend taking into account the following expert advice:

1. The switches are installed inside the car; you need to choose a hidden location. The toggle switch contacts are connected to the outputs of the carburetor or starter device, depending on the type of device. The switch must be connected to the negative circuit. It is possible to connect wiring to standard buttons, for example, to control optics, stove, heating rear window etc. Using multiple switches will save you a lot of time.
2. The muffler valve can be closed. This will allow the power unit to be blocked a few minutes after its unauthorized start. As a result of the obstruction of exhaust gases, the engine does not function properly. The criminal may be under the impression that the vehicle is malfunctioning. There is a possibility that the burglar will then flee the crime scene.
3. One of simple options— installation of a magnetic latch designed to block the transmission or steering wheel.
4. It is possible to install a ready-made immobilizer; the blocker can be purchased at the store. Installation is carried out on the section of the electrical circuit used for starting and providing proper operation car engine.
5. If you have a radio transmitter, install it in a hidden manner to the starter device or carburetor. This will ensure that the circuit is closed when an attacker tries to break into the car.

Homemade version of the “secret”

You can make a “secret” yourself using the example of creating a device to block the starter and ignition system:

1. Remove the plastic trim around the steering wheel and ignition switch.
2. Locate the wires that go to the starter.
3. It is necessary to crash into an electrical circuit. To do this, remove the insulation from a section of the wire and connect the contacts of the radio transmitter to it.
4. Securely fix the device, and the place where the device crashed must be insulated.
5. Check the operation of the blocker. Included with the transmitter is a special device, the effect of which on the radio transmitter leads to restoration of the circuit. The driver must carry it with him.

Safety precautions

When creating and connecting a blocker, the terminals are disconnected battery. This is a mandatory condition, otherwise you will cause a short circuit and failure of other electrical equipment.

To create a “secret” car owner must have knowledge and skills in the field of electronics. Incorrect connection can lead to blocker failure.

pros

Advantages of "secrets":

1. Affordable price for many consumers. If the car is not equipped with an anti-theft system, then installing a secret lock will be the most budget option to provide protection.
2. Good efficiency. When triggered, the “secret” will take up a significant portion of the attackers’ time. In practice, hijackers who encounter the presence of a secret blocker leave the crime scene.
3. The connected blocking device consumes virtually no energy. You don't have to worry about the battery draining. Even if the battery is discharged, the presence of a “secret” will not affect its performance.
4. The secret button allows you to provide the proper level of protection for the car along with other anti-theft devices, for example, alarms or sensors.
5. The device can be installed in any machine model as Russian production, and a foreign car.
6. When installing the “secret”, the main systems of the vehicle are blocked. Depending on the model, this may happen after three or five password attempts.
7. The main advantage is that a criminal cannot intercept the signal, as is the case with a car alarm.

Minuses

According to reviews, such devices have a minimum of disadvantages. Blockers may malfunction, but this is the exception rather than the rule.

• When you go to the store, take your original wheel bolt with you. If you use different wheels in winter and summer, then the bolts may differ - take both with you. This will help you navigate not only the size of the fastener, but also the type of connection to a specific wheel (cone or sphere).
• The presence of deep coded elements on a “secret” fastener usually indicates low quality metal. That is, the manufacturer fears that small elements will not withstand proper tightening. But the deep ones can easily be opened.
• Steel wheels are generally more difficult to protect than alloy wheels. Access to the fasteners is not difficult, so attackers silently twist the secrets with a gas wrench. But, on the other hand, there are much fewer hunters for “steel”.
• If you install two locks on each disk, this will not allow a thief to use the method of tightening adjacent bolts to loosen the tightening force of the lock.
• It is often advised to tighten the “secret” fasteners to incomplete torque. If the goal is to make life easier for crooks, then this advice, of course, makes sense. But good-quality locks, as our tests have shown, calmly pull at the standard torque, allowing for several dozen cycles of unscrewing and wrapping.
• Security nuts for studs have a greater height than bolts, and on steel disk will stick out a lot. Therefore, it is better (from a protection point of view) to install alloy wheels on hubs with studs.
• The most advanced thieves make a cast of the “secret” wheel fastener. The simplest attachments from the threaded part of the neck will help you track whether this happened on your machine. plastic bottle and traffic jams. Found that the traffic jam has disappeared? It is possible that they are interested in your wheels. Among other things, such caps will help keep secrets clean.
• The locks do not have a real effect on the balancing of the wheel, since they are located near the center of rotation. For reference: the mass of the standard wheel bolt in our case was 69 g, and the mass of each of the locks is indicated in the description.
• Operating a vehicle without at least one wheel bolt (nut) is prohibited. Don’t be too lazy to take a quick look at the fasteners before your trip.

IN modern world, when the development of various types of technologies occurs very quickly, motor vehicles are not a luxury item, but a comfortable means of transportation.

About the benefits personal car public transport is not worth mentioning. A large number of cars, especially in big cities, become the target of thieves.

Statistics say that in our country alone, every day an average of 50 applications are received from victims about the theft of their vehicles.

The situation is a little better in others major cities, but car owners are faced with the acute question of means of protecting their movable property.

There are many popular varieties, they come in both mechanical and in electronic format. But secrets are in particular demand, attracting users with their reasonable cost, ease of use and effectiveness.

They are an excellent addition to an alarm system. They are difficult to detect, because the attacker will not have enough time to perform all the actions he needs.

What it is

Mechanical means for protecting vehicles are not a new thing, because back in the USSR, homemade driver locks with hidden buttons and toggle switches were invented that could compensate for the lack of satellite surveillance or an alarm system.

The attacker did not know the location of the button, so even after breaking into the interior, he could not start the vehicle.

It took a long time to deal with such contactors and circuit breakers, which in most cases prompted the burglars to plan a retreat.

The only crime he could commit was to steal various items and equipment from a car dealership.

These days on the market in wide range Electronic anti-theft systems are presented.

But even their versatility and modernity do not provide an absolute guarantee of safety to the vehicle owner, because attackers have also invented devices that intercept codes and signals that disable the security system.

Even now, a large number of motorists resort to old mechanical devices, the search for which will mislead any thief.

Experts also recommend using secrets as additional protection, because fashionable alarms can be bought through online stores, studied, and found weak points that you can use for your own purposes.

Thus, it is clear that modern system alarms together with a secret mechanical device will guarantee maximum protection any vehicle.

Such secret buttons and toggle switches are called secret buttons, because attackers do not know their exact installation location in order to turn off the entire device.

Finding it will be extremely difficult, because it does not reproduce any code signals, so they cannot be intercepted using communication devices.

Even with a strong desire, a thief will not be able to move the vehicle from its place, because one of the important systems will be blocked. Only the owner who knows about its location can disable the secret.

It is possible to use a security system that requires pressing a whole combination of buttons, which will maximize the guarantee of vehicle protection. After all, in addition to discovering the “secret button,” the attacker will need to unravel the combination, which will take a lot of time.

At the moment, many companies are engaged in the production of anti-theft secrets. Over time, devices improve and acquire new additional functions, change appearance.

But the principle of their operation remains the same - the presence of a secret control button or toggle switch.

Modern secret phones have received a number of new functions and have begun to compete with car alarms in terms of functionality. For example, they allow you to automatically turn off the engine.

If a thief breaks into the cabin, then when the wrong key combination is pressed, the engine stalls and does not start until it is unlocked.

We can safely say that secrets are a whole complex in protecting a vehicle, which can be effective even when the car alarm is inactive.

What types of car anti-theft secrets are there?

There are different types of such devices. They are based on completely different operating principles.

The great popularity of security guards contributes to the constant development of their production, the invention of new types that can even replace a full-fledged protective system for cars. They have a lever, button, toggle switch or immobilizer.

Secrets can be classified into two classes - electrical and mechanical.

The first of these includes:

• a toggle switch that breaks the electrical circuit when the starter is ignited;
• a toggle switch that blocks power to the electric pump that supplies fuel to the unit;
• ignition lock.

They may have motion sensors, a built-in stun gun, or an encoder. TO mechanical secrets relate:

• locks in the form of bolts and nuts with special designs, keys with unique prints and a lock;
• and vehicle doors;
• locks for the hood and trunk;
• exhaust pipe blockers.

In reality there are many more varieties. We invite you to familiarize yourself in detail with the features of the most popular secrets.

Breakers

Car owners often choose this type of locking device. It received this name because of its operating principle - like a circuit breaker. This means that pressing the button may break the low-voltage circuit.

Just a couple of decades ago they were considered unreliable and even dangerous; for example, they were not supposed to be placed under a torpedo.

Therefore, now the secret works on the principle of blocking electronic ignition in the ignition box, in the electric fuel pump. But the name of the device remains the same.

Its installation has become possible on many vehicle components. The secret release does not always have a “secret button”.

It can be disguised as an unimportant detail (for example, a lever or button for raising the glass on the doors or blowing the front window).

To fully guarantee the safety of the vehicle, you can use a whole combination of keys that will lock and unlock the mechanism.

Often, manufacturers offer to create “deceptions” for thieves, when some buttons are directed in one direction, and the rest in the other. All this confuses burglars and takes away their time to find a solution to the situation.

There are no beacons on the breaker, so the device does not show signs of life, it cannot be detected even by special wave recognition sensors.

An attacker will spend a lot of time recognizing the relay and searching for the required combination of buttons. As a result of most cases, he abandons the theft process and goes into hiding.

Fuel solenoid valves

Electronic fuel valves operate on a similar principle: they cut into the fuel line system and have a secret output to one of the buttons, which is hidden behind an inconspicuous part inside the car interior.

In vehicles where carburetor and diesel engine, the valve is placed between the pump and the tank. This means that the car will be able to travel a certain distance in a short period of time until the “engine” pumps everything available and then stops.

It will be unprofitable for a burglar to poke around in the vehicle components to find out the cause of the breakdown.

The device is easy to use, but it requires compliance with safety precautions and proper installation.

Squibs

This type is latest development companies specializing in the production of automotive protection.

But it can be unsafe for thieves because it shoots acrid smoke or special gas, which are placed in some squibs. Therefore, not everyone decides to install this type of security system.

The car owner is afraid that he himself may become a victim of such a protective device when he forgets to press a key combination.

How they work

To choose the secret that is required for your case, you should understand the operating principles of each of them. Sellers and manufacturers' representatives are informed about this in detail.

Let's consider the functionality of the device, which consists of one relay and a contact key. The device looks primitive, but it allows you to block the power branches responsible for the functioning of the vehicle engine.

The most ordinary toggle switch will be ineffective due to the fact that it requires leaving the car interior to switch. The diagram below does not show such a drawback.

The name of the protection device is “trick relay.” It can be used to protect absolutely all types of vehicles that have constant pressure with the ignition on +12 V.

These circuits include powering injectors, igniting vehicles, and feeding spark plugs in coils.

In order to turn on the ignition, you should use the “secret switch”. Then the contact closes, the device is in the on mode until the engine is turned off.

When the vehicle stops operating, the relay opens. The next time you turn on the ignition, you will need to press the same “secret switch” that is displayed on any device responsible for its operation.

For example, you can use a window regulator, a heater air regulator, and the like.

Advantages and disadvantages

There are no perfect inventions, therefore secrets have both positive and negative characteristics.

But if you deactivate them, the vehicle will remain completely unprotected. Experienced attackers know the principle of their operation, so they will not stop even in front of them.

The only drawback is that they do not guarantee absolute safety of the vehicle. Experienced burglars know all the possible locations of hidden buttons, so they can even probe seats.

But even an anti-theft lock - the most primitive device - can be used wisely when supplemented with an alarm or other means of protecting cars.

How to choose

In order to choose a secret lock suitable for your case, you should know the principle of their operation and your needs for protection.

As a rule, there is not a huge difference between all types of such devices, because they function on the principle of blocking the operation of any of the car parts, without which the engine will not start.

It takes the attacker quite a lot of time to expose and eliminate them, which discourages the desire to steal a car.

1. Pay attention not only to the cost of the device, but also to its capabilities.
2. Give preference to reputable manufacturers in this market.
3. Before purchasing a secret, you need to ask for testing

These simple steps will allow you to choose a vehicle protection product that suits your needs and expectations and will last for many years.

Price of devices

Mechanical anti-theft locks for a car will be much cheaper than their electronic counterparts.

We invite you to familiarize yourself with the analysis average cost secretok in Moscow and St. Petersburg:

Indicators indicate that different types secretok have an affordable pricing policy regardless of the region. The cost varies due to the complexity of the system and the name of the manufacturer.

How much does it cost to install

You can make the connection yourself, but there is a high risk of damaging the device and harming your vehicle due to lack of skills.

For example, a car anti-theft lock on the pedal can be installed by the motorist independently, but devices that relate to the functioning of electronic parts or fuel units require professional installation.

Installation cost in Moscow and St. Petersburg:

Statistics show that installing a secret lock will cost motorists more than the cost of the device itself. Therefore, you should wisely weigh all your skills and the cost of safety equipment. An experienced technician will always install the device more reliably and will not harm the car.

A car anti-theft security system is considered one of the most effective vehicle protection systems, because it is not profitable for attackers to leave the vehicle interior once again.

Locks, as a means of protecting a vehicle, cannot be considered something supernatural and reliable.

Their main and initial task is to prevent burglars from taking possession of vehicles by taking up their time and putting them in an awkward situation.

More than 70% of cases of using secrets show that such a locking system can be quite effective.

Because the attacker is caught red-handed, even when the alarm is not working, although he often does not want to deal with possible “problems” for a long time, especially when he needs to look under the hood of the car, he leaves everything to his own devices and disappears from the scene.

When thinking about an anti-theft project, you should consider what system components you will need, their cost, and the potential savings. The latter does not mean that before you can secure your car from theft with your own hands, you need to buy low-quality products. After all, many are able to install an immobilizer or locking devices themselves. It remains to consider the available components of protection against car theft and their purpose.

The constant modernization of cars and an increase in the number of thefts leads to the improvement of protective equipment, the emergence of new types and combinations anti-theft devices. Today the following types of equipment are in operation:

• Electronic.
• Mechanical.
• Radio search engines.
• Satellite.
• Transponder.
• Biometric.

The last four types are complex technical means and require special skills and knowledge during installation. But electronic and mechanical systems may well be organized independently. At least the electronics, if not installed, are not difficult to modify.

Block No. 1 or how to protect your car from theft using electronic means

TO electronic devices These include time-tested “secrets” – toggle switches, buttons and mechanically opening contacts. Often, a standard car button is used as a secret contact, duplicating it with a hidden toggle switch.

More advanced devices are distinguished by the presence of shock, motion, volume and opening sensors with subsequent interruption of the ignition or fuel supply circuits. Decent results are demonstrated by the use of an immobilizer, the task of which is to prevent the car from being stolen “under its own power.” Modern automakers know how to protect a car from theft, therefore almost all vehicles are equipped with a standard immobilizer. This security system can have several configurations that block a specific node, but in two different ways:

• Using a contact mechanism, starting the engine is possible only if you have a key coded specifically for a specific immobilizer.
• Using a contactless mechanism, a coded card acts as a key, which only needs to be in the car’s interior for the driver to be able to start the engine. If you take the card out of the cabin, you will no longer be able to start the internal combustion engine. The only drawback– it is not possible to install such a system yourself, and its cost corresponds only to expensive models.

Modification of the standard immobilizer

The immo block, which contains transponder codes, compares the response pulse with its list. If the answer is in the list, then permission to start the engine is sent to the ECU. The problem lies in the following nuances:

• the memory of the immobilizer unit contains codes for two chips on the keys that come from the factory;
• You can enter the encoding of up to 8 transponders into memory, i.e. it is allowed to produce additional keys and then register them in the block’s memory;
• Additional chips can be added to memory only when connected to the service connector.

It is this last loophole that hijackers take advantage of. They connect a scanner or completely deactivate the immo block. The question is, how to protect your car from theft with your own hands without much expense and effectively? Simple - you need to remove the service connector. To do this, just follow these simple steps:

• Carefully unwind the cable to the connector;
• cut off the section of the cable with the connector (with a spare wire);
• in the place of the cut, solder two male-female connectors from any device (computer equipment);
• secure the new connector.

From now on in your car contact Group, the wiring diagram of which cannot be recognized the first time. The other part of the cable can be stored at home when you have to go to a service center - just insert the male into the female and use a standard connector.

What to do if you want autostart?

For remote start engine, the immobilizer needs to recognize the key chip. How is this implemented in general terms? The car contains a container (“crawler”) with a coil similar to the one in the ignition switch. A key with a transponder or just a transponder is placed in it. The coil contacts are connected via a relay in parallel to the outputs of the standard inductor. It would seem that there should be no problems in the question of how to protect your own car from theft, but they can easily arise:

• Unscrupulous autostart installers simply take away the second key, leaving the owner with one. It would be smart to introduce the third chip into the immo memory and place it in a container.
• The thief just needs to remove the lock lining and discover the connection to the coil and find the container with the chip. That is, the criminal does not even need a scanner - he has a working transponder.
• The “walker” cannot be hidden far from the ignition switch - there will be significant signal attenuation.

Block No. 2: how to effectively secure your car against theft with your own hands using mechanical means

From the name it is clear that these means mechanically prevent fraudsters from trying to get into the car. Although electronic systems are easier to operate, mechanical devices are popular due to ease of installation, reliability and affordable price. Although the combined use of these options gives the maximum anti-theft effect.

Any car enthusiast will be interested in learning how to secure his own car from theft with high-quality and inexpensive locking devices. mechanical devices. Among these means of combating fraudsters, the most popular are:

• Steering wheel, pedal, door and wheel locks.
• Special locks for the ignition switch, gearbox and hood.
• All kinds of “secrets” (for example, pins installed in certain parts of the machine).

Important! Each type of locking mechanism is designed for use with a specific car component. When selecting additional protection, you should consider the make and model of your car, because some products are made with design features car.

You can choose mechanical locks yourself or leave this matter to specialists. Let's look at the most affordable blockers.

Door locks

They are retractable pins that work like door bolts. The latches are driven by an electric drive, after which the doors can only be opened by violating its integrity. Usually installed at the end of the door. In the presence of positive aspects this method has its disadvantages:

• the need for radical intervention in the door structure, which can lead to body corrosion;
• the need to install locks on all doors to obtain a full anti-theft effect.

Steering locks

Since the standard lock is not particularly reliable, additional mechanical protection is designed to prevent criminals from “stealing” the car. Suitable for car owners from budget segment and those who have not yet decided how to protect their own car from theft, because:

• the equipment has a low price;
• convenient to use.

Naturally, such a device can only resist novice car thieves. Unfortunately, the “sharks” of the criminal business overcome such blockages quite quickly.

Gearbox locks

Popular protection among car enthusiasts, which makes it impossible to change gears. Based on their design and operating principle, products of this type are divided into two types:

The first type is a lock with a screwed bracket. The latter, in turn, is attached to the body. Installation of the device is not particularly difficult and can be done by a motorist with minimal experience.

The pin version involves installing an additional pin in a special hole to prevent the movement of gears or forks. However, you can engage the gear from the engine compartment, so a secret lock on the hood won’t hurt at all.

Hood lock

The device is mounted directly on the hood and comes in two types:

• with a mechanical drive that opens with a special key;
• with an electromechanical drive that operates from an electronic signal.

As a separate security device, the hood lock can resist professional car thieves for no more than two minutes. However, as an additional measure, a lock is quite relevant.

Eventually

Every motorist who thinks about how to protect personal car against theft with your own hands, you must take into account that the protection must be comprehensive. This is the only way to achieve maximum efficiency. It only makes sense to install any one device if:

• the car is of no interest to car thieves and belongs to the inexpensive category;
• lack of funds.

According to experts, the cost anti-theft system should be at least 5-10% of the price of the car. If money is tight, then we install a programmable “secret” budget class and we hope for the low qualifications of the thief, who is not ready to cope with additional problems other than the immobilizer.

An ideal anti-theft system should consist of several components. Moreover, they should be selected in such a way that the functionality is mutually enhanced, and the unsatisfactory aspects are compensated.

Do-it-yourself anti-theft car secrets.

A security lock is a special device that effectively protects the car from theft by preventing the engine from starting or turning it off when starting to move. Such a device is installed independently of the main security system, creating an additional line of property protection. Such devices can operate either with standard control buttons or with hidden buttons, in the form of switches, touch buttons and other options.

The purpose of the secret is to increase the time required to steal a car. The iron principle of a thief is to do his job very quickly. If the machine does not yield to his manipulations within 3-5 minutes, then the attacker leaves it alone.

Rules for installing secrets

Before installing another anti-theft agent on your car, you need to carefully evaluate and think through a number of points:

Location of the button. The toggle switch should be placed so that it can be used by natural movements. Before the car is stolen, they monitor the car, and if you make unnatural movements before starting the engine, crawl under the pedals or recline the seat, then determining the location of the switch is a trifle. The location of the button installation must be approached competently, responsibly and with imagination. In the glove compartment, under the steering wheel and under the seat, car thieves immediately look for the toggle switch. The switch can be disguised in door handle, gear shift lever, steering wheel; can be combined with some not too important element control (heater switch, headlights or something like that); can be disguised as a mounting bolt next to the ignition switch - the main thing is that it is not conspicuous, does not require unnecessary movements and is located in a non-standard place.

Additional features. The secret must provide service function– something like a VALET mode on alarms, so as not to give up its presence when carrying out work at a service station;

Work with other anti-theft systems. The secret must work in parallel with any other anti-theft system, and also not impair additional alarm functions (for example: automatic engine start).

Let's look at the types of electronic secrets in more detail:

Push-button. A simple and cheap option for secret locks. The toggle switch is placed in the power supply gap of the device being blocked (starter, fuel pump, ignition coils).

Advantages: ease of installation, low cost (only a toggle switch and wires are required).

Disadvantages: arming is done manually, is not compatible with systems automatic start engine, it is not possible to use the car's standard buttons.

Push-button with relay. Each time the engine starts, the button will need to be pressed for a second; pressing the button will turn on the relay, while the relay contacts will remain closed until the ignition is turned off, but when the ignition is turned off, the circuit opens itself, and there is no danger that you will forget to turn on the secret.

Advantages: relative cheapness (only a toggle switch, relay and wires are required). Arming is performed automatically.

Disadvantages: arming is performed immediately after the ignition is turned off, there is a slight difficulty in implementing the connection, it is not compatible with automatic engine start systems, it is not possible to use the car’s standard buttons.

Specialized devices that are armed automatically and disarmed by pressing a secret button. Blocking can occur at the start of movement (for automatic engine start systems) or immediately when the ignition is turned on.

Advantages: simple installation, arming is done automatically, arming is done some time after the ignition is turned off, compatible with automatic engine start systems, it is possible to use standard car buttons.

Disadvantages: the price is higher than that of a simple secret lock; movement is determined by manipulating the pedals.

For example: our AMK00100-AMK00106 series devices are for cars with an automatic engine start system; there are also options for cars without an automatic engine start.

Specialized devices with a motion sensor, armed automatically, disarmed by pressing a secret button, blocks the circuit when trying to move the car, combined with automatic engine start systems.

Advantages: simple installation, arming is done automatically, arming is done some time after the ignition is turned off, compatible with automatic engine start systems, motion detection is done using an acceleration sensor, it is possible to use standard car buttons.

Disadvantages: high price (comparable to immobilization systems).

Any secret for a car from those described above can be created without much difficulty - but only if the electrical equipment is familiar to you. If you are not very familiar with circuits, entrust this matter to professionals: tampering with the electrical circuit can lead to expensive repairs.

Do-it-yourself anti-theft secret for a car (car) - diagram

No issue related to cars has as many dark spots as the issue of effective and affordable anti-theft protection. It is unclear how effective this or that immobilizer or anti-theft system really is - in fact, such information is not publicly available.

Anti-theft manufacturers trumpet their victories and sing advertising songs about “super-technological”, “unhackable”, “fully protected” and “unreadable” systems. Otherwise, who will buy all this stuff? Drivers who have lost their cars (despite the installation of scattering “unhackable and unreadable” systems), in turn, criticize the installers and manufacturers of security systems, which is also understandable. At the same time, the majority of car owners, who have not yet encountered thieves personally, timidly listen to both and generally support the skeptical opinion “if they want to steal, they will steal.”

Why is this happening? First of all, because the anti-theft system “comes into action” very rarely: hardly every 60th car, if you count on average for all liquid models and brands, is subject to attack by hijackers. The way “anti-theft devices” behave during daily use cannot, of course, serve as an assessment of their real effectiveness: here we can only talk about the quality of workmanship (“works or doesn’t work”). It’s like with an airbag: until you fly into someone at good speed, you won’t check it.

So it turns out that the general opinion about anti-theft systems is formed by biased “ends of the spectrum”: on the one hand, sellers and advertisers, and on the other, car owners who have suffered from thefts, who (thank God!) are still an overwhelming minority relative to everyone. Insurance companies that have large fleets of insured vehicles have real statistics, but their risk managers, who are responsible for creating requirements for the installation of anti-theft systems (AUS) for CASCO insurance, in most cases are poorly qualified and these requirements are often born crooked and do not take into account weight important points. Plus, one cannot discount the element of corruption, namely the gratuitous influence of manufacturers and sellers of all kinds of anti-theft “toys” on the same risk managers: “uncle, please include our new, expensive miracle-yudo-mega-super-alarm in the requirements, and we We’ll give you some chocolate.” Unfortunately, the consumption of “chocolates” is going full swing, so, in general, insurers are not an option as a source of real information about the effectiveness of certain POS.

The bottom line is that only professional centers specializing in the installation of PUS (not to be confused with dealer car services - these rather play into the hands of car thieves, see http://5koleso.ru/articles/obzory/kak-obmanyvayut-v-avtosalonah) , can provide the consumer reliable information. Those of them who have been on the market for a long time have accumulated solid experience in how to create real problems for hijackers. However, here the question comes down to whether this or that representative of the anti-theft business will want to share the true secrets of his craft with his clients. And life shows that they usually don’t do this. Why? The answer is obvious: it all comes down to money. Why tell a person who is willing to pay 30 thousand rubles for a set of anti-theft devices that the same effect can be achieved for half that amount?

So car owners will have to improve their literacy themselves. And so that anyone can understand the principle of necessity and sufficiency when selecting a PUS, we have developed a universal scheme for protecting against theft of any car. Today, this scheme is unique, having no analogues not only in our country, but also abroad. The diagram is made in the form of an intuitive “road map”, which specifies the sequence of installation of the control system components, and is also provided with detailed comments on each type of anti-theft systems. All types of control systems used in practice are discussed here, which allows you to avoid serious mistakes: any competent anti-theft specialist will say that the installation order is fundamentally important - 70% of success depends on it. For example, it doesn't make much sense to install a lock on the transmission without installing a lock on the hood, and installing an immobilizer without the same hood latch is also ineffective - etc. and so on. Also, building a clear installation sequence automatically regulates the budget: the required minimum (the so-called basic protection) is immediately visible, and any additional PUS are added depending on the state of finances.

The developers provided the map with “ road signs", establishing the priority of some control systems over others, the direction of movement, etc.

Finally, we will formulate the most important points that you need to know about anti-theft protection:

1. Protection must be comprehensive. It only makes sense to put one thing if:

a) the car is not classified as high-risk and is not too expensive (for example, a used Citroen C3, Opel Astra and so on.);

b) very bad with money.

Then we install a budget programmable “secret” and hope that the hijacker will not be ready for any additional problems, except standard immobilizer. In all other cases, it is necessary to install a PCU complex, i.e. "something plus something." The principle of comprehensive vehicle protection is so important that it would not be a sin to repeat it:

It is necessary to install not one, but several anti-theft devices, and in such a way that their effect is mutually enhanced, and weak points are compensated.

The diagram clearly indicates the minimum complex - this additional immobilizer plus a hood lock. Everything else is welcome, but in the 2nd, 3rd, etc. queue, with respect to priority.

Relative exceptions are the lock on the steering shaft (which, alas, is inconvenient to tinker with) and the search beacon, which does not prevent theft, but helps to find a stolen car.

A skeptic will say: well, if a car costs two million, it’s clear that for 40 thousand you can come up with something interesting. What if its price is 600 thousand? Then 2% = 12 thousand, and what can you bet on this money? We answer - if you search the Internet, then for this amount it is quite possible to find a set of “programmable secret plus a hood lock”, i.e. basic protection. And the issue will, in general, be resolved, so the “2% Rule” really works!

3. Programmable immobilizer-secret. This is the most burglar-resistant immobilizer available today, and it still requires the installation of a hood lock.

4. Anti-theft marking glass Useful for absolutely all cars and really reduces the likelihood of theft by 4-5 times. From experience, the effect increases with the cost of the car.

5. Car alarms are not a serious anti-theft device. Its task is to signal an attempted theft. Connecting a blocking relay to the alarm does not turn it into an immobilizer, because does not stand up to any criticism, primarily due to the lack of secrecy of the installation, and also in 90% of cases - resistance to reading the radio code.

6. Satellite search and security system. Remains relevant when retrofitting basic protection (additional immobilizer, best of all a programmable secret immobilizer plus a hood lock). Moreover, when protecting a car with the highest risk of theft and value, it is, with that said, still necessary.

7. Search beacon (bookmark). Really effective stuff. With proper installation and performance monitoring, its efficiency is at least 70-80%, and this figure is stable. But it is necessary to remember that the bookmark does not prevent theft in any way, and if the thief turns out to be meticulous and guts the entire car, he will most likely find it.

And finally, the most important thing. If you have protected your car in a professional installation center (not to be confused with a dealership!) and have not allowed yourself to be fooled into spending too much, the likelihood of theft is reduced by approximately 80%, i.e. the car becomes essentially non-hazardous.

Security for a car against theft - types and level of protection

The secret for a car is additional remedy protection that reduces the likelihood of theft or theft. Most often, such devices are used:

• Breakers. Disconnect the low-voltage network and prevent the engine from starting. This could be a button hidden under the panel or a more sophisticated device connected, for example, to the blower system or windshield wipers (until you turn on the heater or windshield wipers - the anti-theft secret for a car will allow you to start the engine).

Breakers.

If you are well versed in auto electrics, you can make a car lock with your own hands. However, you shouldn't place too much hope on it. Such means of protection can only scare off hooligans and random car thieves.

Professional car thieves can easily find and disable almost any secret. In this case, the only way to reliably protect against theft is a closed garage in your own guarded home.

Lock bolts - will they protect against wheel theft?

Due to the increasing number of thefts of expensive rims Locking bolts (securing nuts), installed instead of standard fasteners, are gaining particular popularity.

As a rule, they have non-standard heads that require a special key. You can buy security locks of this type with an adapter key at any auto store, which also does not make them a panacea against thieves.
Lock bolts

More complex versions are made of high-strength alloys and have a round head with notches recessed inside. Removing the locks from the wheels is only possible with the help of special clamps.

The complex design of such bolts can play a cruel joke not only on the wheel thief, but also on the car owner. Dirt that gets inside very quickly clogs the mechanism, which often leads to complete blocking. As a result, the bolts will have to be removed using special tools.

How to make a secret lock for a car with your own hands?

In order to make an anti-theft lock for a car with your own hands, you need to know the intricacies of the electrical system. The abundance of electronic systems in modern cars significantly complicates this task.

Do-it-yourself anti-theft secret for a car.

Incorrect connection of a homemade device can cause a short circuit and fire. Therefore, for the installation of any additional systems, we recommend that you contact only trusted services that are ready to provide guarantees.

By installing anti-theft locks on a car with your own hands, you risk not only your own, but also other people’s property, because a sudden fire may also damage cars parked next door.

If we are talking about protection against wheel theft, then you can order bolts for an individual shape and head size from any experienced turner. But after losing the exclusive key, the only way to remove the wheel is with the help of an angle grinder.

How to make an anti-theft lock for a car with your own hands?

Anti-theft locks are electrical, which prevent the engine from starting, and mechanical, which prevent the wheel from being unscrewed and stolen. The simplest secret can be an ordinary toggle switch located in some secret place. It can break the power circuit fuel pump, ignition or starter relay circuit. Special nuts or bolts for wheels - simple. But very reliable protection from their theft.

Unique electronic secret – the most effective protective agent, preventing car theft. Even if some thief takes out your keys with a key fob, he will not start the car, since he will not know in which secret place the button is located that blocks the engine from starting. At the same time, it is important to make sure that car alarm used other blocking methods.

Secret as an addition to the alarm system

The secret is an important and necessary addition to any alarm system. Today you can easily buy scanners that disable up to 95% of existing alarm systems. For this reason, things have become more likely to be stolen from cars, because thieves can now easily turn off the alarm. For this reason, you should not leave any valuables in the car, as sometimes robbers use a simple brick instead of a scanner. The theft takes place in a matter of seconds, and you are unlikely to be able to catch up with the thief.

Types of electronic secrets

Nowadays, there are secret lockers that work using different control algorithms or have different security and service functions:

• sequential button presses;
• secrets with hood lock control;
• secrets with a limited time for entering a code;
• sequential input of a specific code using standard or additional buttons;
• secrets with motion sensors;
• secrets with siren connection.

Benefits and additional features

Wheel locks

TO important advantages The use of anti-theft systems includes the following:

1. Electronic secrets cannot be read using software devices that hijackers began to use long ago.
2. By installing a secret lock under the hood and equipping the car mechanical protection, you will not allow an attacker to disable the device or detect it.
3. No one can steal a deactivator from a motorist, like a key fob for an alarm system.

Additional functions

Modern models of electronic security locks have a number of possible additional functions:

1. Motion Sensor. This function allows you to start the car, but you will not be able to drive it. This option is great for use in winter when warming up the car.
2. The Anti-Hi-Jack function is a modern addition to the anti-theft system. She works due to automatic locking operation of the motor in the case when the owner opened the door without performing any special actions that only he knows about.

Homemade secrets

You can break the starter or carburetor circuit by connecting a toggle switch installed in some secret place to the negative wire. Lay the wires leading to the usual keys in the cabin (headlight range adjustment, heater activation). Thus, by connecting several similar toggle switches, you can gain some time.

Another option for a homemade secret is to close the exhaust pipe valve, which is controlled remotely. When you start the engine, it will stall after a while. Traffic fumes will not be able to go anywhere, so the car will give the thief the impression that it is faulty, so the attacker will try to leave the crime scene as quickly as possible.

Try installing an additional lock to block the gearbox or steering wheel. Special magnetic latches are especially convenient and effective in this case.

In every radio parts store you can find a radio transmitter, the principle of which is that the circuit will close when you approach it. It should be connected to the wires leading to the starter or carburetor, and also carefully hidden. Main disadvantage system is that you will need to carry the transmitter with you.

Factory secrets

You can find various immobilizers on sale in the form of factory secrets. Recently, it has been observed that such devices are increasingly being installed on all modern cars. If you don’t have anything like this, you can install such a device yourself by connecting it to one of the electrical circuits of the machine, which is responsible for the normal operation of the motor.

If you have experience in installing such devices, try a system that allows you to extend the time it takes for a hijacker to unlock your device. To do this, you need to create a system with complex algorithm influence on reed switches and several interlock circuits that activate the relay. If you do not have sufficient experience, entrust the installation of the lock to a professional in a workshop.

Installing or creating a car lock with your own hands will allow you to increase the security of your car for little money.

Car thieves do not disdain not only the cars themselves, but also expensive equipment, both external (headlights, nameplates, lights) and internal (radio tape recorders, radars, video recorders, navigators). The wheels also come into their field of vision, because to remove it from the car, you just need to unscrew 4 bolts. And together with a forged disk it can reach quite a significant sum.

And although cars are now equipped with alarm systems, they often go off when there is an impact on the body. When removing the wheels, these impacts are minimal, and if everything is done carefully, then removing the wheel from a car that has been alarmed is not very difficult.

What is a secret lock in a car?

To prevent wheel thieves from dismantling them, special wheel bolts and nuts are used that have a special secret turnkey profile. They are popularly known as wheel locks.

Note that secrets are not a new development; they appeared a very long time ago - before the start of the Second World War. They were invented by car owners in the northern regions of Italy to combat car thieves in the southern regions, who often stole not only cars, but also the wheels from them.

And now secrets are gaining popularity again, because they allow you to minimal costs protect your car wheels.

A lock is a special wheel fastener (bolt or nut) that has a non-standard profile, which makes it impossible to unscrew it with a regular wheel wrench. To unscrew and screw in locks, special keys are used that are shaped to match the profile of the fastening element. This key comes complete with the wheel bolts and should be kept in a safe place by the driver.

That is, everything is simple, the lock cannot be unscrewed with ordinary keys or devices, so a thief simply cannot steal the wheels, of course, if he does not have a key of the appropriate shape.

Video: How to choose secrets: revelation from a specialist

Types and their features

There are several types of secrets:

• with external turnkey profile;
• with internal profile;
• cone-shaped.

Each of these types of secrets has its own design features, advantages and disadvantages.

Secrets with an external profile - quite simple, but not very reliable way protect the wheels from being removed. In essence, it is a regular bolt or nut with a slightly modified profile. It can be triangular, in the shape of a star or some other type, the main thing is that it is not a hexagonal one (like a regular key).

Such secrets are inexpensive, and you will never have problems with dirt when unscrewing them. But it won’t be too difficult for an attacker to unscrew them. The fact is that even an ordinary wheel wrench or socket wrench suitable size when put on such a lock, its edges are capable of catching on the profile of the bolt.

The second option that an attacker can use is powerful pliers or pliers with extended handles. With this tool he can easily grab the bolt and unscrew it.

Security bolts with an internal profile are more reliable in terms of protection. In such secrets, the profile for the key is made in the form of a recess or hole of a complex shape (star-shaped, multi-beam, asymmetrical, etc.), and the key is a rod of a certain shape that exactly fits the shape of the hole. The outer profile of a bolt or nut has a perfectly round surface.

It is impossible to unscrew such a secret without a key. Using pliers or pliers will also not bring results, since their jaws will simply slide off the round surface.

Some models of such secrets are equipped additional elements– protective rings around the outer circumference. These rings rotate freely on the bolt, making it impossible to snag on the outer surface of the bolt. This further increases the protective function of the secretions.

But this type of secret is more expensive, and there is also one serious problem when using them, during operation the internal profile becomes clogged with dirt, so such a secret is often very difficult to unscrew even with a special key for it. This problem is especially relevant for fasteners with very complex hole shapes. Dirt or ice (in winter) simply clogs the edges and the key cannot be installed. Therefore, the car owner has to very carefully clean the hole, which, due to its complex multifaceted shape, is not so easy to clean.

Some models of secret boxes with an internal profile are equipped with protective caps that protect the holes from contamination, which somewhat eliminates the problem of clogging.

Video: 5 ways to remove wheels. Will McGard secrets help?

The third type - cone-shaped bolts have a tip made in the form of a cone with an offset center. It is impossible to unscrew such a bolt using a regular wheel wrench or pliers, since the surface of the cone is smooth and it is impossible to catch on it.

But this type also poses inconvenience to the car owner himself. The fact is that it is very difficult to create the force necessary for unscrewing with the key of a lock that has the form of a rod with a hole for a cone; the key simply moves relative to the center of the cone.

What else is important in secret?

But not only the type of secret plays an important role, but also the material from which it is made. Inexpensive Chinese-made security bolts are usually made from ordinary unalloyed metal, which has weak strength. Therefore, drilling it or making notches for hooking with pliers will not be difficult.

Key points that are important when choosing a secret

High-quality secrets are made from high-quality materials that can withstand drilling quite strongly.

The shape of the pattern also affects safety. Locks can have from 8 to 40 edges of various shapes, and the more there are, the more difficult it is to unscrew the bolt without a special key.

The number of batches released also plays a role in the reliability of secrets. A low cost indicates a large number of issued batches, which means that there is a possibility that an attacker will be able to pick up the key. But there are also secret ones, the production of batches of which amounts to only a few dozen. Such bolts have very high reliability, an exclusive shape of edges, for which it is almost impossible to match the key.

It is worth noting that locks are not suitable for ordinary steel disks, since the thickness of the disk is small and the bolt head is located outside. But car thieves are also the least interested in such cars, since they often “hunt” not for tires, but for wheels, and a steel rim is not of particular value.

Therefore, the locks are more designed for use with cast and forged disks, which have a thickening at the attachment point, and the bolts themselves go deep inside them.

What to consider when choosing?

Video: How to remove the secret from a wheel

Now let's look at what you need to consider when choosing secrets for your car:

1. Complexity of the pattern. The more complex its shape, the more difficult it will be to unscrew the bolt without the special key included in the kit.
2. Availability of all certificates. Wheel bolts from well-known manufacturers have their own identification numbers, which is proof of their high quality. In addition, the identification number will help in case the key included in the kit is lost. By providing the identification number to the manufacturer, you can recover the key.
3. Bolt length. Here you should choose a lock, the length of which will correspond to the standard wheel bolt. A discrepancy in size may have a negative impact on use. A bolt that is too long will either not be able to attract the wheel and it will dangle or will rest against the elements brake system. A short one will either break the thread when tightened, or will not “sit” securely and will unscrew during operation.
4. Secure head dimensions. The head should not protrude beyond rim, but completely recessed into seat. Otherwise, it will not be difficult for an attacker to unscrew such a secret, even if there is a security ring.
5. Availability of protective caps. This is important, especially with internal profile secrets. This way you can protect yourself from clogging the hole with dirt and making it impossible to unscrew the secret even with a special key.

How to unscrew a wheel lock without a key

Video: Removing wheel locks.

Using security locks can really prevent wheel theft, but it can also cause a lot of hassle. And this can happen if a special key is lost. Although the set comes with two of them, there are situations when there are simply no keys.

Note that the set of locks consists of 4 bolts, that is, one for each wheel. Therefore, to remove the wheel, you need to unscrew only one bolt with a specially shaped head, the other three are standard, unscrewed with a balloon.

But if there is no key, then you should not first unscrew the standard bolts, but on the contrary, they need to be tightened to the maximum, this will reduce the persistent force of the disk on the lock. Next, fill it with WD-40.

Then you can try to apply a notch with a thin chisel to the end surface of the secretion, which will later act as a stop. All that remains is to use the same chisel and hammer to carefully try to tear the bolt out of place, resting against the notch.

If no methods to unscrew the locks help, all that remains is to weld an additional bolt to it with a welding machine, and then unscrew the lock through it. But this method should only be used when as a last resort, since there is high probability damage to the disc and tires.
