Utilizing specific techniques, it is possible to copy a standard car key but not a transponder key. In contrast to the remote central locking element of a conventional key which uses battery power, a transponder chip is powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy that is detected by a microchip inside the key. The chip then sends a unique code to the immobiliser in your car. The car's computer compares the code in its memory to the one from the transponder chip and if they match, the engine will start.

If the immobiliser detects an unauthorized transponder or key is in use it will shut down the engine and prevent the essential components from working.

This may require the system to be reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and then restart the vehicle. This will reset the system and make it ready to accept the key again.

The security light is an immobiliser's method of alerting you to a problem. If you attempt to start your car and the light is solid on it means that the chip inside your key isn't compatible with the code that is stored in the ECU. This could happen in the event that your car's key has been replaced with an alternative key that is not compatible with the vehicle, or if an ECU was not swapped correctly.

If this is the case, then you need to go to a professional and have the key or the transponder chip properly programmed to your vehicle. It is possible that the system won't accept the key because of a software update or bug. To test, put your key into the ignition and turn it to the ON position. Do not attempt to start the car. Keep the key in this position for ten minutes. This should cause the security lights to come on and then to turn off. If it doesn't, you'll have to repeat the process and wait for another 10 minutes.

The system won't allow the car to begin if it does not receive the correct code. Certain models will even notify the owner when they attempt to use a wrong fob or key.

The system isn't foolproof, however. Certain thieves have been able to get around the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires through a vehicle's wiring to fool the ECU to believe that the proper key or fob is being used. This method is risky and requires extensive expertise to avoid electrocuting yourself. Modern car thieves are using more advanced methods, for instance, Bluetooth or specialised apps to obtain information about a vehicle and remotely manage it.

Car owners often be greeted by warning lights that indicate an immobiliser malfunctioning. It can occur for a variety of reasons, but one of the most frequent causes is a dead or defective battery in the key fob. A simple repair should resolve the issue.
