It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to prevent your engine from starting if you have a duplicate of your key. It works by sending a radio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer matches the signal sent by the key the immobiliser will then be disarmed 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 duplicate than mechanical keys. It is possible to duplicate a standard key, but not a transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip the ignition cylinder must be turned to the ON position. The ring emits a burst IR energy that is detected by a microchip inside the key. The chip responds by sending auto key repair a unique code the immobiliser in your car. The car's computer compared the code stored in its memory with the one from the transponder chip, and If they are compatible, the engine will start.
If the immobiliser detects an unauthorised transponder, key or other device is being used, it will disable the engine and block the essential components from working. The car won't move when the engine isn't functioning. It is easy for a criminal to hot-wire it to drive away.

This anti-theft device stops anyone from starting their car without the proper keys. If the system cannot detect a serial number digital from the chip inside your key, it will disable the engine immobiliser and prevent the car from getting started.
The car immobiliser is a great way to deter thieves, but it could sometimes get out of in sync. This can be caused by interference or the system becoming too sensitive. This could need an adjustment. To do this, simply disconnect the battery. Then leave it off for around 15 minutes before reinstalling it and start the vehicle. This will reset the system and make it ready to accept your key once more.
The security light is an immobiliser's way of alerting you to an issue. If you try to start your car and the light stays on, it means that the chip in your key isn't compatible with the code that is stored in the ECU. This could happen if have recently replaced the car key with a different one that was not programmed to the vehicle or when you've had a damaged swapped ECU.

Modern cars have this system as standard. This makes it really hard to hot-wire the car or use a different key for starter. The system works by analyzing the chip in a key fob or 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 hasn't been compromised. The system won't allow the car to start if it doesn't have the correct code, and some models will even report back to the owner in the event that someone attempts to use an incorrect key or fob.
However the system isn't impervious to theft. Some thieves have bypassed the immobiliser by using techniques such as 'hot wiring.' This involves crossing the wrong wires through a vehicle's wiring to fool the ECU into thinking that the appropriate fob or key is being used. This method is risky and requires a lot of experience to avoid electrocuting oneself. Modern car thieves are also employing more sophisticated methods, for instance, Bluetooth or other specialized apps to steal a car's information and remotely manage it.

If you experience any of these issues it is a great idea to consult the local car dealer or garage to seek help.
