The key that is equipped with a transponder chip is sometimes called a 'fob' or a "smart" key because it is much more difficult to clone than a traditional mechanical key. Using specific techniques, it is possible to copy a conventional car key but not transponder keys. Contrary to the remote key fob repair central locking element of a standard key which uses battery power, a transponder chip powered by the infrared (IR) signal that is 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 blast of IR energy that is absorbed by the microchip within the key. The chip then responds with a unique code to the immobiliser inside your car. The car's computer compared the code in its memory to the one from the transponder chip and If they are compatible, the engine will start.

The system operates by sending a passcode from the key fob to the ECU. The ECU will then verify that it's the correct key and that the passcode hasn't been compromised. The system will not allow the car to start if it does not receive the correct code. Certain models will even notify the owner when they attempt to use an incorrect fob or key.

The system isn't completely impervious to attack, but it is. Some thieves have gotten around the immobiliser by using techniques such as 'hot wiring.' This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU into thinking that the correct key or fob is being used. However, this is extremely risky and requires a lot of experience to do it without electrocuting yourself.
