The system examines the code to ensure it's correct. If the code is not correct it will disable the elements that are crucial to start the car, like the starter motor or ignition.

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 the ignition cylinder has to be in the ON position. The ring emits a burst IR energy which is detected by a microchip inside the key. The chip responds by sending a unique code the immobiliser in your car. The computer in the car examines the code in its memory to the one on the transponder and when the two codes match it will start the engine.

If the light is on when you attempt to start your vehicle, it indicates that the code in the ECU does not match the chip in the key.

The system will not allow the vehicle to start if it doesn't receive the correct code, and some models will even notify the owner if someone tries to use a wrong key or fob.
The system isn't foolproof, however. Some thieves have been able to get around the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking that the appropriate fob or key is being used. However, this is extremely dangerous and requires a lot of experience to do it without electrocuting yourself. Additionally, many modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to steal the car's information and remotely control it from their phone.
Car owners often see warning lights that indicate the immobiliser is malfunctioning. It can occur for a variety of reasons, but one of the most common is due to a damaged or dead battery on the key fob. This issue can be resolved by replacing the battery.
