Its goal is to prevent the engine from starting when someone else has an identical key. It works by sending radio signals from the key to the immobiliser system. If the code on the car's computer matches that signal transmitted by the key, it will disarm the immobiliser and allow the engine to begin.
The key with the transponder chip can be referred to as a 'fob' or a 'smart' key because it is more difficult to clone than a conventional mechanical key. It is possible to duplicate a traditional key but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip the ignition cylinder needs to be switched to ON. The ring emits a blast of IR energy which is absorbed by the microchip in the key repair car. The chip responds by sending a unique code the immobiliser in your car. The computer in the car compares the code stored in its memory to the one on the transponder and when the two codes match, it will start the engine.

The security light is an immobiliser's way of alerting you to a problem. If you try to start your 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 can happen if you have recently replaced the car key with one that was not programmed to your vehicle or if you've had a bad swapped ECU.

Modern cars come with this system as standard. This makes it really hard to hot-wire the car or use a different key as a starter. The system works by analyzing the chip inside a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU will then verify that it's the correct key and that the passcode isn't compromised. The system won't allow the car to start if it does not receive the correct code. Some models even notify the owner if they attempt to use an incorrect fob or key.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser using methods like hot-wiring.
