Modern technologies make it possible to protect the vehicle from the hijacking and hacking. Oddly enough, most of the car owners in the old manner use an ordinary castle. More advanced drivers are installed on their cars powerful anti-theft systems, but the third is not completely worried about their "iron horse" because it is under reliable immobilizer protection. Unfortunately, many motorists did not even hear about such devices, although experts consider them future automotive security. About this further in the article.

What is immobilizer, why is it needed

With the literal translation of the names of this device from English, we will get the word "immobilizer". This term maximally transmits the entire essence of the immobilizer action - the elimination of even the slightest possibility of launching the automotive motor without the participation of the keys owner.

In fact, the immobilizer is a whole complex of different electronic sensors blocking certain vehicle systems without allowing the ability to move your car from the scene. As a rule, the entire ignition system is blocked using an immobilizer or a fuel supply system in a power unit. So, even if the hijacker and managed to get into the car's salon, he won't leave everything on it.

The principle of the immobilizer is pretty simple. When a stranger is trying to start a car, the device breaks the electrical circuit than blocks the signal supply from the ignition. The great advantage of this device is after breaking the wires or attempts to "neutralize" the vehicle is completely blocked. In other words, if the immobilizer system fixes the hacking attempt, then immediately responds to the way that is also blocked, both of themselves and all vehicle systems.

Immobilizer activation occurs automatically. That is, if you left the car unattended for a certain period of time, soon the device reacts itself and blocks the car. Therefore, it is ultimately not recommended to leave the vehicle without keys, since you will not be able to get into the salon.

Immobilizers what they happen

According to the key, these devices are contact and contactless. The latter are also called transponder immobilizers. The difference between them is whether the key comes in the process of removing the immobilizer from the protection of contact with the device. In the contact devices, the key directly contacts the immobilizer. As for non-contact devices, the key label in them is simply close to the system of system, which, as a rule, is 5-10 meters.

The second type of immobilizers (vehicle) is more preferable and safe, since when using these systems, the hijacker is actually deprived of the possibility of determining the type of an inserted anti-theft system, including the immobilizer. Not rare the immobilizers of the vehicle type are also equipped with an additional function - anti-dissemination. This function provides an applying of the device to the key during the path and, if the label is not at the device in the field of action, the electric circuit of the car is broken, and its motor operation is blocked.

Immobilizer keys, for which you need keys and how much should there be

Since the immobilizer is designed to protect the car from the hijacking, then access to activation and deactivation of the device is exclusively at the car owner. Initially, all immobilizers embedded at the factory are not programmed, i.e., they disabled the protection function. The program setting is most often carried out by car salon workers when selling a car or owner independently activates it. The kit includes 3 keys, 2 of which are workers, and the third (red) intended for training the system.

Immobilizer or automobile system, which is better

The advantage of the immobilizer in front of the anti-theft alarm is based on the fact that it is hidden from third-party eye and does not give himself up until the hijacker, penetrated into the salon, will not try to start the car. As a rule, the attackers are carefully prepared for the hijacking and know in advance whether the security system is installed in the car, its type and methods of shutdown. Learn about the presence of the immobilizer is very and very difficult. In addition, in the absence of a special key, it is impossible to start the vehicle, so the probability of hijacking is actually reduced to zero.

Immobilizer makes it possible to catch a car, what is the chip

Recently, immobilizers are becoming increasingly prevalence, allowing the hijacker to start the vehicle and even drive a certain distance. The device is activated at a certain time when the hijacker will overcome some part of its path. As a result, the vehicle freezes in the middle of the road, well, and the Warr is nothing else, except to leave the car and quickly "make legs". The alarm is primarily intended to scare the potential robber.

Tools, fixtures, consumables

You can turn off the immobilizer yourself, but it will take patience and time. It is much easier to resort to the help of specialists who will qualitatively and competently fulfill the entire procedure. If you still decided to resolve the problem on your own, you will need the following materials and tools:

1. PC or laptop.
2. Wrench on "10".
3. Screwdriver.
4. Insulating tape.
5. Pack loader.

Immobilizer how to disable immobilizer with your own hands (step by step)

On most cars, the immobilizer shutdown is carried out by a similar scheme:

1. The first thing to find out is the location of the immobilizer. For example, in the models of the VAZ family, it is located above the electronic control unit, slightly above the side panel.
2. Next you need to grope it with your hand and dismantle from the block connector.
3. It is no secret that this connector has twenty contacts.
4. First, clean the ninth canal, and then eighteenth. After that, they are cut.
5. Next, connect them again and exhibit them.
   
6. After deletion, restore the line on which the diagnostics is made, for which the jumper is made, the connection between the electronic unit and the diagnostic shoe.
7. After connecting, the operation of the K-Line is restored.
8. By completing these work, you need to return the connector into place.

The flashing is made in this way:

1. First dismantle the electronic unit.
2. Connect a package loader to the controller connector.
3. Next, read the factory firmware.
4. We save this firmware on your computer.
5. Disconnect the bootloader, collect the controller and return to the place.

Failure in the ignition system, how to make a car bypassing the immobilizer but save alarm

Sometimes, as a result of the presence of such a device in the car in the ignition system, it fails, which is most often ends with the engine blocking and lack of ability to start it. And if the automotive engine is provided in the car, then if there is an immobilizer, it will not be possible to use it. How then to bypass the immobilizer so that at the same time keep the opportunity to take advantage of all the advantages of alarm?

To exit this situation, there are a number of ways. To select a suitable, consider all possible options. But you need to know that any bypass reduces the level of protection of your vehicle. Therefore, before you begin, think about it is more important for you - the convenience or safety of the car?

we go around the immobilizer with an additional key, pros and cons

The use of an additional key is the cheapest and simple way that can be used even without buying additional equipment. You will need only to secure the second key in the immobilizer function. Moreover, it must be done so that the system is constantly in the stage of unlocking. This bypass method is more suitable for modern cars. The additional key is best to fix under the cover of the panel, where it is immeasured. The disadvantage of this option is to reduce the safety of the car.

use the anti-theft system with built-in bypass unit, pros and cons

This method implies the acquisition of an anti-theft system with a built-in bypass unit. Connection is made by taking a signal with a control keychain, thus allowing the autorun system to start a car. This method saves the safety of your car at a fairly high level.

we bring immobilizer from the ignition scheme, pros and cons

It will not be needed to constantly leave the key in the car, but the safety of the vehicle is still decreasing. It is important to experience the installation of electrical equipment in order not to damage the car in the wrong work.

install an additional immobilizer crawling unit, pros and cons

This method is fully effective, since the additional unit has its own remote control, which allows you to first turn off the immobilizer and then start the car. This unit all the time gives a signal to the system, as if the key is constantly in the car.

TEP PROFI: The engine control unit is a complex system, so ...

Unfortunately, there is a number of shortcomings. First, the vehicle can start moving spontaneously during autorun if it was left on the transmission enabled. Often it happens with old models with a manual gearbox. In order to avoid this, it is desirable to purchase alarm with a built-in neutral sensor.

Secondly, you should not forget that the anti-theft system with remote launch reduces the protection of the car. So if the vehicle coited, and the immobilizer was turned off at the same time, you may have trouble with an insurance company.

The main thing when walking and turning off the immobilizer is the correct calculation of our own opportunities and forces. After all, the motor control unit - the system is quite complex, so I can do it without certain skills and knowledge can be dangerous: illiterate intervention leads to a vehicle breakdown. In addition, you are subject to the car to the hijacking, so before bypassing or turning off the immobilizer, we carefully consider the need to perform this procedure.
