Its goal is to stop the engine from starting when another person has a duplicate of your key. It works by transmitting an audio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer matches the signal transmitted by the key, the immobiliser will be removed and the engine will be able to start.
The key with the transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. It is possible to duplicate a conventional key but not a transponder key. Transponder chips are powered by an infrared signal not battery power.

The system will not allow the vehicle to start if it doesn't receive the correct code, and some models will even inform the owner if someone tries to use an incorrect fob or key.
The system is not impervious to attack, but it is. Some thieves have been able to bypass the immobiliser by using techniques like 'hot-wiring'. This involves crossing the wrong wiring in a vehicle in order to fool the ECU. But, this technique is quite risky and requires a great deal of knowledge of how to accomplish it without cutting yourself.
