It is possible to duplicate a conventional key but not a transponder key. Contrary to the remote central locking element of a standard key that relies on battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.

To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits IR energy that is picked up by a microchip in the key. The chip responds with an individual code to the immobiliser in your car key immobiliser repair (https://yambroker77.bravejournal.net/5-laws-that-anyone-working-in-keyrepair-should-know).

If the light is on and you attempt to start your car, it is a sign that the code in the ECU does not match the chip in the key.

The immobiliser will stop working when it is unable to recognize the code. That's why it's so difficult to beat.

Modern cars have this system as standard. This makes it difficult to hot-wire a vehicle or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU then knows that it's the right key and that the passcode hasn't been compromised. The system won't allow the car to start if the doesn't have the correct code. Some models will even inform the owner if a person tries to use a wrong fob or key.

The system isn't completely foolproof, however. Some thieves have gotten around the immobiliser by using techniques like 'hot-wiring.' This involves using the wrong wiring in a vehicle in order to fool the ECU. However, this is pretty dangerous and requires a lot of experience in order to carry out the procedure without cutting yourself. Modern car thieves are using more advanced methods, like Bluetooth or other specialized apps to obtain information about a vehicle and remotely manage it.
