It is possible to duplicate a standard key, but not a transponder one. In contrast to the central locking element remote of a conventional key which is powered by batteries the transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.

To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst of IR energy that is absorbed by the microchip inside the broken key repair car key remote (images.google.com.sv). The chip responds by sending a unique code your car's immobiliser. The computer in the car analyzes the code stored in its memory with the transponder's code and if the two codes match it will begin the engine.

The system works by analyzing the chip in the key fob or a key and sending a passcode back to the ECU (electronic control unit). The ECU is then able to determine that it's the right key and that the passcode hasn't been compromised. The system will not allow the car to start when it doesn't receive the correct code. Certain models will even notify the owner if they try to use an unapproved fob or key.
