What does an immobilizer do

All car owners would like to provide their cars with permanent protection. However, until 1992, it was much more difficult to secure your car against theft than it is now. All because the immobilizer was invented only that year. This electronic device prevents the car engine from starting when the wrong key or key fob is used. You can also not worry that your car can be stolen by starting the engine by bypassing the ignition system. Therefore, since the mandatory use of immobilizers, the number of car thefts has decreased significantly. If you're still wondering if your car has an immobilizer, then you may not because the presence of an immobilizer is a rule for all car manufacturers. In addition, immobilizers that were installed at the factory where the car was manufactured are considered the most reliable type. All because they were installed correctly and fit your car model.

How does an immobilizer work

If you are still wondering what an immobilizer is, then in general, the principle of operation of the immobilizer is quite simple. Thus, immobilizers accept the code transmitted by transponder chips that are installed in key fobs and smart car keys. Thus, when you want to start the car and insert a key fob or key into the ignition, the code is transmitted from the transponder chip to the engine immobilizer, and only if the code is correct, the car will start. In addition, modern car manufacturers have introduced a two-level security system, which includes fixed and variable codes for starting the car. At the same time, the immobilizer first checks the fixed code and then reads the variable code and compares it with those stored in the database. Only if both codes match, you can start the car. You can also learn about the privileges of car key fobs in our article in the blog.
If the wrong code is used to ignite the car, then the car immobilizer displays a sound signal. Also, certain modern car systems transmit information about a possible car theft attempt to the security service. This way, the security company can contact the user and check whether they really tried to steal the car.

Is an immobilizer worth it

How safe are immobilizers

Therefore, installing an immobilizer is a very reasonable investment in ensuring the safety of your car. While installing other security devices will enhance your security, with an immobilizer you can be sure that your car is safe.
