Also known as a chip key or a 'transmitter & responder' key, it is designed to prevent the engine from starting if someone else has the same key. It functions by sending an audio frequency signal from the key to the immobiliser system inside your car. If the code stored in the computer of the car matches the signal sent by the key, the immobiliser will be deactivated and the engine will start.

The key with the transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to copy than mechanical keys. Utilizing special techniques, it is possible to copy a standard car key, but not a transponder key. Unlike the central locking element remote of a standard key which uses battery power, a 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 needs to be turned to the ON position. The ring emits a burst IR energy which is detected by a microchip in the key. The chip responds by sending a unique code to the immobiliser of your car. The computer in the car compares the code stored in its memory to the one on the transponder and if the two codes match, it will start the engine.

If the immobiliser is able to detect an unauthorised transponder, key or other device is being used it will shut down the engine and prevent the essential components from functioning.

If the system cannot detect a digital serial from the chip in your key, it will shut off the engine immobiliser to stop the car from starting.

The car immobiliser is a fantastic method of deterring thieves, but it could sometimes be out of in sync. This can be due to interference or an immobiliser that is too sensitive. This may require a reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes then reinsert it and start the vehicle. This will reset the key system so that it is ready to accept your keys once again.

The security light is a way of alerting you to a problem. If the light is on and you try to start your car, it is a sign that the code stored in the ECU is not compatible with the chip in the key. This can happen if you have recently replaced your car's key with a different one that isn't programmed to your vehicle or when you've had a damaged swapped ECU.

Programming

Modern cars come with this system as standard. This makes it very difficult to connect the car to a hot wire or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU knows it's the correct key and that it doesn't have to been compromised code. The system won't allow the car to begin in the event that it does not receive the correct code. Some models even inform the owner when they attempt to use an incorrect fob or key.

The system isn't completely foolproof, however. Some thieves have been able to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking the correct key or fob is being used. This is a risky method and requires extensive expertise to avoid electrocuting yourself. Modern car thieves are employing more sophisticated methods, such as Bluetooth or other specialized apps to take over a car's data and remotely manage it.

Owners of cars will often see warning lights that indicate an immobiliser malfunctioning. This can happen for various reasons, but one of the most frequent causes is a dead or defective battery on the key fob. This problem can be fixed by an easy replacement.
