A tiny electronic chip, referred to as transponder, is embedded inside the head portion of your car keys. This technology was introduced in cars made after 1995. Also referred to as a 'chip key' or a 'transmitter and responder' key, it is designed to stop the engine from starting if another person has the same key. It works by sending an audio signal from the key to the immobiliser system. If the code in the car's computer is in line with the signal sent from the key, it will disable the immobiliser and allow the engine to begin.

The key with the transponder chip is often referred to as"fob" or a 'smart' key because it is more difficult to duplicate than a conventional mechanical key. It is possible to duplicate a traditional key but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.

To activate the transponder the ignition cylinder must be in the ON position. The ring emits a burst of IR energy which is detected by the microchip in the key. The chip then sends a unique code to the immobiliser in your car. The computer in the car analyzes the code stored in its memory with the one on the transponder and If the two codes are identical, it will start the engine.

If the system is unable to detect a digital serial number from the chip in your key, it will deactivate the engine immobiliser, preventing the car from beginning.

The car immobiliser is an excellent way to deter thieves, however it can occasionally be out of the sync. This can be due to interference or the system being too sensitive.

The security light is the vehicle immobiliser's way of telling you that there is an issue with the system. If the light is on when you attempt to start your vehicle, it indicates that the code that is stored in the ECU is not compatible with the chip on the key.

Modern cars have this system as standard. This makes it very difficult to wire the car hot or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU then knows that it's the correct key and that the code isn't compromised. The system won't permit the vehicle to start if it does not receive the correct code, and some models will even notify the owner if a person tries to use an incorrect fob or key.
