What is immobilizer

Today, almost every car that has come down from the conveyor is equipped with an immobilizer. And those cars, the factory equipment that does not provide for such a component, are increasingly seen by them thanks to their caring owners. What is the wonder and do you need it?

"Immobilizer" translated means "immobilizer". In fact, it is a security device and protects the car from the hijacking. The microprocessor opens the internal circuits of the engine, thus blocking the fuel supply, ignition or other vital functions. As a result, the vehicle becomes efficient only when the program identifies a unique key.

The market presents immobilizers of two types:

Contacts that are activated by a special key. In simplified models, the chip is mounted directly to the ignition lock key. Other devices suggest a separate key similar to those used for intercoms, or code lock. Lack of this type in low secrecy. That is, if desired, the attacker may choose a combination of numbers or try to disassemble the primitive system.
Contactless requiring a programmed card. In the case of a small radius-like immobilizer, the map or its analogue must be reduced to the reader at a distance of about 10 cm. The hypothetically hijacker can spill an exemplary location of the device and attempt to damage it. Devices with a large radius of action are the ideal option. They take a signal at a distance of one or two meters. The owner of the car, being in the cabin, does not make any additional actions, the chip and receiver are in contact without any assistance. In this case, the presence of a security system is almost impossible to detect, and the car remains under reliable protection.

Overview of immobilizers models on our website.

There are still devices in one aspect. Most models block the engine operation when the chip is far away or the machine does not function for some time. But there are also immobilizers with a launch deferment. That is, the hijacker will be able to start the car and even start moving. But after a few minutes, protection works, and the on-board computer gives an error for an error, the machine does not go further. On the busy street, the thief will not be able to understand the problem, it is easier for him to throw "prey" and not attract attention to his person.

The chip of a high-quality immobilizer is that it is mounted in the oven or regular appliances. The receiver signal does not see, you need to know about its specific location. And if the thief wants to find the wires of the device, it is also awaiting Fiasco. The insides of a properly installed immobility are disguised under the usual wiring.

It is important to take into account that the immobilizer is not an analogue of alarm and does not replace it. He will not be able to prevent unauthorized penetration into the salon, will not notify the owner of the car on an attempt to open the castle. For efficient protection, it is necessary to comprehensively use the immobilization and alarm. Extended functions that allow us to turn the device into a full-fledged security complex, only a narrow model range of immobirizers has.

Since the device ensures security, some measures should be observed during its operation:

make a spare key and store it separately from the main one;
when you lose the chip, recode the system;
do not hang the key chain on the overall bundle of keys, and do not keep the card in the wallet;
if there is no immobilizer in your car, but you plan to install it, contact a certified point, preferably in the neighboring city to eliminate the likelihood of naughtly on the hand of specialists.

The established immobilizer guarantees almost 100% hijacking protection. But he will become an assistant only when his owner was not too lazy to explore the instructions and knows the principle of handling a specific model of the security device.
