Using specific techniques, it is feasible to copy a conventional car key but not transponder keys. Contrary to the remote central locking element of a conventional key, that relies on battery power the transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.

To activate the transponder chip the ignition cylinder needs to be turned to the ON position. The ring emits a burst IR energy which is detected by a microchip within the key. The chip then responds with an individual code to the immobiliser inside your car. The car's computer analyzes the code stored in its memory with the transponder's and if the two codes match it will start the engine.

Modern cars are fitted with this security system in the standard configuration. This makes it very difficult to hot-wire a vehicle or use a different key for starter. The system works by analyzing the chip in a key fob key repair or a key and transmitting a passcode to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that there hasn't been compromised code. The system will not allow the car to start when it doesn't receive the correct code. Some models even inform the owner if they attempt to use an unapproved fob or key.
