Also known as a 'chip key or a 'transmitter & responder key, it's designed to prevent the engine from starting if a third party has a copy of your car key. It works by sending a radio frequency signal from the key to the immobiliser system in your car. If the code in the car's computer matches the signal transmitted by the key, it will deactivate the immobiliser and allow the engine to begin. The key that has the transponder chip is often referred to as”fob” or a “smart” key due to the fact that it is more difficult to copy than a traditional 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 has to be in the ON position. The ring emits a flash of IR energy which is picked up by the microchip inside the key. The chip responds with a unique code to the immobiliser of your car. The computer in the car analyzes the code stored in its memory to the one on the transponder and If the two codes are identical, it will start the engine. If the immobiliser detects an unauthorised transponder, key or other device is in use, it will disable the engine and block the essential components from functioning.

It should be left disconnected for around 15 minutes then reinsert it and begin the vehicle. This will reset the key system to ensure that it is ready to accept your keys again. The security light is an immobiliser's method of warning you of the presence of a problem. If you try to start your car and the light is solid on it means that the chip inside your key isn't in sync with the code that is stored in the ECU. This could happen in the event that your car's key was replaced with a new one that is not programmed for the vehicle, or if an ECU was not swapped correctly. If this is the case you should take your transponder or key chip to a professional to get them correctly programmed for the vehicle you are driving. There is also the possibility that the system is not accepting the key because of an update or software issue. To test this, put your key in the ignition and turn it to the ON position but don't try to start the engine. The key should remain in this position for ten minutes. The security light should turn on, then turn off. If it does not you'll need to repeat the procedure and wait for another 10 minutes. This should resolve the issue if you repeat it three times.

Certain thieves have been able to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wire in a vehicle in order to fool the ECU. However, this method is pretty risky and requires a lot of knowledge of how to accomplish it without cutting yourself. Modern car thieves are using more advanced methods, for instance, Bluetooth or specialised apps to steal a car's information and remotely control it remotely. Car owners often see warning lights that indicate that the immobiliser is malfunctioning. This can happen for various reasons, but the most common is a dead or defective battery in the key fob. A simple repair should resolve this problem. If this does not work it could be because the transponder chip is defective or the ECU is not matched.
