It works by transmitting an audio signal from the key to your immobiliser system. If the code stored in the car's computer is in line with the signal from the key, it will disarm the immobiliser and allow the engine to begin.
The key with the transponder chip is sometimes called a 'fob' or a smart key due to the fact that it is more difficult to clone than a conventional mechanical key. Using specific methods, it is possible to copy a standard car key, but not transponder keys. Contrary to the remote central locking element of a conventional key that relies on battery power, a transponder chip powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder has to be switched to ON. The ring emits IR energy which is picked up by a microchip within the key. The chip responds by sending a unique code the immobiliser in your car. The car's computer compares the code stored in its memory to the one from the transponder chip and if they match, the engine will start.
If the immobiliser detects that an unauthorised transponder, key or other device is being used it will shut down the engine and prevent the essential components from working.

The system works by checking the chip inside a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the right key and that the passcode isn't compromised. The system won't allow the car to start in the event that it does not receive the correct code. Some models even notify the owner when they attempt to use an unapproved fob or key.
However it isn't completely secure. Certain thieves have been able to get around the immobiliser using methods like hot-wiring. This involves crossing the wrong wire in a vehicle to trick the ECU.
