The system then checks the code to ensure it is correct. If it is not then the system will disable parts that are essential to start the vehicle, such as the ignition or starter motor.

With the help of specific methods, it is possible to copy a conventional car key but not transponder keys. Contrary to the remote central locking element of a conventional key which is powered by batteries, a transponder chip powered by the infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.

To activate the transponder chip, the ignition cylinder needs to be switched to ON. The ring emits IR energy which is detected by a microchip within the key. The chip responds by transmitting a unique code to the immobiliser of your car. The computer in the car examines the code in its memory to the transponder's and If the two codes are identical it will start the engine.

If the immobiliser is able to detect an unauthorized transponder or key is being used, it will disable the engine and block any of its essential components from working.

This could be due to interference or an immobiliser that is too sensitive. This could need an adjustment. To do this, disconnect the battery. After 15 minutes, reinstall the battery and restart the vehicle. This will reset the system and allow it to accept your key again.

The security light is an immobiliser's method of warning you of the presence of a problem. If you attempt to start the car but the light stays on, it means that the chip inside your key isn't compatible with the code stored in the ECU. This can happen when your car's key was replaced with a new key that's not programmed for the vehicle, or if the ECU has been swapped incorrectly.

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 if they try to use an incorrect fob or key.

However the system isn't impervious to theft. Some thieves have gotten around the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU to believe that the correct key or fob is being used. However, this is extremely dangerous and requires a lot of experience to do it without electrocuting yourself. Modern car thieves are employing more sophisticated methods such as Bluetooth or other specialized apps to steal a car's information and remotely control it remotely.

Car owners are often faced with warning lights that indicate that the immobiliser is malfunctioning. This can occur for many reasons but the most frequent reason is a defective battery in the keyfob. This problem can be fixed by a simple replacement.
