With the help of specific techniques, it is possible to copy a conventional car key, but not a transponder key. In contrast to the central locking element remote of a conventional key that relies on battery power, a transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To activate the transponder chip, the ignition cylinder must be turned on. The ring emits a flash of IR energy that is detected by the microchip inside the key. The chip responds by sending a unique code to the immobiliser of your car. The car's computer compared the code in its memory with that from the transponder chip, and when they match the engine will begin to rev.

The security light is an immobiliser's method of alerting you to a problem. If the light is illuminated and you attempt to start your car, it is a sign that the code in the ECU does not match the chip inside the key. This could happen if you have recently replaced your car key with a different one that has not been programmed to your vehicle or in the event that you've had a defective swapped ECU.

This is why it's so hard to beat.

Modern cars come with this system as standard. This makes it difficult to hot-wire a vehicle or utilize a different key for starter. The system works by analyzing the chip in a key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU then knows that it's the right key and that the code isn't compromised. The system won't allow the car to start if it does not receive the correct code. Some models even notify the owner when they attempt to use an unapproved fob or key.

The system isn't 100% secure, however. Some thieves have been able to get around the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking that the correct key or fob is being used. This is a risky technique and requires a lot of experience to avoid electrocuting oneself. Modern car thieves are employing more sophisticated methods, like Bluetooth or other apps that obtain information about a vehicle and remotely manage it remotely.
