If the code on the car's computer matches that signal sent from the key, it will disable the immobiliser and allow the engine to start.
The key with the transponder chip can be referred to as"fob" or a smart key because it is much more difficult to clone than a conventional mechanical key. It is possible to duplicate a standard key, but not a transponder one. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip, the ignition cylinder must be switched to ON. The ring emits a burst IR energy that is detected by a microchip within the key. The chip responds by transmitting a unique code to your car's immobiliser. The car's computer compared the code in its memory to the one from the transponder chip and If they are compatible, the engine will start.

The security light is the vehicle immobiliser's way of telling you that there's a problem with the system. If the light is illuminated and you attempt to start your car, it means that the code in the ECU is not compatible with the chip inside the key. This can happen if you have recently replaced your car's key with another that has not been programmed to the vehicle or in the event that you've had a defective swapped ECU.

The ECU then knows that it's the correct key and that the code hasn't been 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 if they try to use an incorrect fob more info or key.
However the system isn't completely secure. Some thieves have bypassed the immobiliser by using techniques like 'hot-wiring.'
