Electronic immobilizer
The engine immobilizer is an essential security feature that can help stop car theft by making sure that only the correct key is used to start the car. This is done by checking the code on the car key with the one stored in a computer. The engine will only be able to start if the codes match. This method has been in use for more than 20 years, and it has drastically reduced vehicle theft rates. It is also a good method to prevent hotwiring which is the practice of bypassing the ignition switch by connecting wires between the ignition coil and the fuel pump relay.
The immobilizer is part the key fob, or key that has transponder. The chip transmits a code to the car's immobilizer system which is embedded in the PCM, BCM, instrument cluster or smart junction box or another module.

Some of these strategies include using a laptop to decode the cryptographic algorithm, which can be accomplished using a special software program.
Another method is to use an instrument to alter the code on the transponder chip or key. This can be done by using a device known as"transponder reader" or "transponder reader" that is available online for purchase. These tools don't work every time, but can be helpful in some cases.
