Utilizing special methods, it is possible to copy a conventional car key however, not the transponder key. Contrary to the remote central locking element of a standard key that relies on battery power, a transponder chip powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a blast of IR energy, which is picked up by the microchip in the key. The chip responds by sending a unique code to the immobiliser in your car. repair car key compared the code stored in its memory with that from the transponder chip, and if they match, the engine will start.

The car immobiliser system is an effective in stopping thieves but sometimes it can become out of sync with the key or transponder chip. This could be due to interference or a system that is too sensitive. If this is the case it may need to be reset. To do this, simply disconnect the battery.

Modern cars are fitted with this security system in the standard configuration. This makes it difficult to wire a car or use a different key as a starter. The system works by analyzing the chip in a key fob or a key and transmitting a passcode to the ECU (electronic control unit).

Some models even inform the owner if they try to use an unapproved fob or key.

However, the system is not completely secure. Some thieves have managed to bypass the immobiliser with techniques such as 'hot-wiring.'
