What is an immobilizer?

A modern car is stuffed with many electronic components, the purpose or even existence of which its owner does not suspect. One of these devices is
immobilizer
– electronic anti-theft device. Manufacturers of security systems are constantly improving and releasing models with different functionality, but they have one task – to block the engine start for everyone except the car owner.

What is an immobilizer?

How do immobilizers work?
Immobilizer literally means "immobilization device" in English. It blocks vital functions of the car: fuel supply and ignition. The immobilizer breaks the electrical circuit or, conversely, turns on the power of the blocking device. Only the owner of the original key can turn off the protection. Even if the intruder tries to break the wires or open the device itself, the system will detect the hacking attempt and block all available equipment. Manufacturers equip immobilizers with an automatic activation function: if the driver does not use the car, after a specified time the system puts it under protection.

What does an immobilizer consist of?
The standard configuration of the device includes three elements:

a control unit that activates and deactivates the protection;

a key by which the system identifies the owner of the car;

electromagnetic relay that breaks the power supply circuit.

Some manufacturers equip the immobilizer with a valve that shuts off the fuel supply. The most modern systems create interference in the CAN bus, which blocks the operation of the car.

Types of immobilizers
Contact
To start the engine, the car owner inserts the key into the ignition switch. After that, the system provides access to the car. The immobilizer key is outwardly no different from the classic one, but inside its head there is an electronic chip, or
label
- validator. There is a reading device in the lock that receives the signal.

One of the types of contact immobilizers is a code website development service immobilizer. To activate it, the car owner enters a combination of numbers on a special keyboard. Some manufacturers equip security systems with scanners, and drivers use fingerprints as keys. While a thief can pick a digital code on his own, he is unlikely to cope with a biometric one. In addition, the immobilizer does not emit a signal that can be scanned with a code grabber. However, contact systems have an obvious drawback: the intruder probably knows where the reading device is located.

Contactless
Contactless immobilizers transmit a signal via a radio channel. Manufacturers of such systems install an electronic chip not in the ignition key, but in the key fob. Specialists hide the reading device under the car's trim in any place. Thus, an outsider does not know where it is located.

The car is unlocked after its owner with a chip gets into the network coverage area - automatically or by pressing a button on the key fob. The service encodes the signal using complex algorithms, and even if the thief has located it, it will be almost impossible to decipher the code without expensive equipment.

Will an immobilizer replace a security system?
The immobilizer and the security system perform the same task - protect the car from theft, so some drivers believe that one of these systems can replace the other. In fact, they differ greatly in functionality. A modern anti-theft system tracks the coordinates of the car via satellite and notifies the driver or security agency about an attempted theft.

The immobilizer only immobilizes the car. It has a relatively small range, but it will take the thief many hours to detect and neutralize it.

Experts note the high efficiency of immobilizers with delayed engine blocking. The thief enters the car, starts the car and even drives several hundred meters before the engine stalls. This situation confuses him, since the car is usually already on a busy section of the road. If the key fob with the chip is stored separately from the general bundle, the engine will stall when the car moves away to a safe distance.

Anti-theft system specialists believe that you should not give preference to just an immobilizer or a satellite car alarm , but combine both into a single anti-theft system. Multi-level protection, thanks to its reliability, significantly reduces
risk
for the car owner.

We offer the latest Cesar Individual immobilizer, which has over 9,000,000 combinations to unlock, which are impossible to pick. Unlike competitive products, if you forget your code, you still have the opportunity to turn on the ignition through multi-stage identification of your identity by calling the service center.
