If the code stored in the computer of the car matches the signal transmitted by the key the immobiliser will be deactivated and the engine will be able to start.
The key with the transponder chip can be referred to as"fob" or a 'smart' key due to the fact that it is more difficult to copy than a traditional mechanical key. It is possible to duplicate a conventional key but not a transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst IR energy which is received by a microchip in the key. The chip responds with an individual code to the immobiliser of your car. The computer in the car compares the code stored in its memory with the transponder's code and if the two codes match, it will start the engine.
If the immobiliser is able to detect an unauthorised transponder, key or other device is in use, it will disable the engine and prevent any of its essential components from working.

This will reset the system and allow it to accept the key again.
The security light is the car immobiliser's way of telling you that there is an issue with the system. If you attempt to start the car and the light is solid on it indicates that the chip inside your key isn't compatible with the code stored in the ECU. This could happen if you have recently replaced your car's key with another that was not programmed to the vehicle, or when you've had a damaged swapped ECU.
