The system checks the code to ensure it is correct. If the code isn't correct, the system disables components that are essential to starting the car, like the starter motor or ignition. The car will be impossible to start if you don't have the correct key.

A small electronic chip, referred to as a transponder, is built inside the head portion of your car keys. This technology was first introduced in cars manufactured after 1995.

It works by transmitting a radio frequency from the key to your immobiliser system. If the code in the car's computer is in line with the signal sent from the key, it will disarm the immobiliser and allow the engine to start.
The key with the transponder chip can be referred to as a 'fob' or a "smart" key because it is much more difficult to copy than a conventional mechanical key. It is possible to duplicate a conventional key but not a transponder one. In contrast to the central locking element remote of a conventional key that relies on battery power the transponder chip is 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 to the ON position. The ring emits IR energy that is picked up by a microchip within the key. The chip responds by sending a unique code to the immobiliser of your car. The computer in the car examines the code in its memory to the transponder's code and if the two codes match it will begin the engine.

The security light is a way of alerting you to the presence of a problem. If you try to start the car but the light stays on, it means that the chip inside your key doesn't match the code that is stored in the ECU. This can happen if you have recently replaced your car key with one that has not been programmed to the vehicle, or in the event that you've had a defective swapped ECU.

The system will not allow the car to begin if it does not receive the correct code. Some models even notify the owner if they try to use a wrong fob or key.
However the system isn't completely secure. Some thieves have been able to bypass the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wiring in a vehicle to trick the ECU. However, this is extremely dangerous and requires a lot of experience in order to do it without electrocuting yourself.
