The key that has the transponder chip is sometimes called"fob" or a 'smart' key because it is more difficult to clone than a conventional mechanical key. With the help of special techniques, it is possible to copy a standard car key however, not the transponder key. In contrast to the central locking element remote of a conventional key that relies on battery power the transponder chip is powered by an infrared (IR) signal that is 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 of IR energy that is picked up click here by the microchip in the key. The chip then sends a unique code to the immobiliser of your car.

It is based on a specific RFID microchip that cannot be duplicated and has its own serial number. The immobiliser will be disconnected in the event that it is unable to recognize the code. It's tough to beat.
Modern cars are fitted with this security system in the standard configuration. This makes it really hard to hot-wire the car or use a different key as a starter. The system works by sending a passcode from the key fob to the ECU. The ECU knows it's the correct key and that there hasn't been compromised code. The system won't allow the car to start if it doesn't receive the correct code. Some models will even report back to the owner if someone tries to use an unapproved fob or key.
