The system examines the code to make sure it is correct. If it is not it is, the system will shut down components crucial to starting the vehicle, such as the starter motor or ignition.

It is possible to duplicate a traditional key but not a transponder key. Contrary to the central locking element remote of a conventional key which uses battery power, a transponder chip powered by the infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be turned on. The ring emits IR energy that is detected by a microchip within the key. The chip responds by transmitting a unique code to the immobiliser in your car. The computer in the car analyzes the code stored in its memory to the one on the transponder and when the two codes match it will begin the engine.
If the immobiliser is able to detect an unauthorised transponder, key or other device is in use it will shut down the engine and block any of its essential components from working.
