The key that is equipped with a transponder chip can be referred to as a 'fob' or a 'smart' key because it is much more difficult to duplicate than a traditional mechanical key. It is possible to duplicate a standard key, but not a transponder one. Contrary to the central locking element remote of a conventional key, that relies on battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits IR energy that is picked up by a microchip inside the key. The chip responds by sending a unique code the immobiliser of your car. The car's computer checks the code in its memory to the one from the transponder chip and if they match, the engine will start.

The security light is the car immobiliser's way of telling you that there's an issue with the system. If you try to start the car but the light stays on, it means that the chip inside your key isn't compatible with the code that is stored in the ECU.

Some models even notify the owner when they attempt to use an unapproved fob or key.
