It works by transmitting an audio signal from the key to your immobiliser. If the code stored in the computer of the car is in line with the signal sent by the key, the immobiliser will be removed and the engine will be able to start.

The key that has the transponder chip is sometimes called"fob" or a "smart" key because it is much more difficult to copy than a traditional mechanical key. It is possible to duplicate a standard key, but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.

To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a burst IR energy that is received by a microchip in the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer compared the code in its memory with the one from the transponder chip, and when they match the engine will begin to rev.

If the system cannot detect a serial number digital from the chip in your key it will disengage the engine immobiliser and prevent the car from beginning.

If this is the case, it could be necessary to reset. To do this, just disconnect the battery. Then leave it off for around 15 minutes then reinsert it and begin the vehicle. This will reset the system and allow it to accept the key again.

The security light is the car immobiliser's method of letting you know that there's an issue with the system. If the light is on and you try to start your vehicle, it indicates that the code that is 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 another that was not programmed to the vehicle or when you've had a damaged swapped ECU.

Some models will even notify the owner if someone tries to use an unapproved fob or key.

The system isn't 100% secure, however. Some thieves have managed to bypass the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wires through a vehicle's wiring to fool the ECU into thinking that the correct key or fob is being used. This method is risky and requires extensive experience to avoid electrocuting oneself. Modern car thieves are also employing more sophisticated methods like Bluetooth or specialised apps to take over a car's data and remotely control it.
