Utilizing specific techniques, it is feasible to copy a standard car key, but not the transponder key. Transponder chips are powered by an infrared signal not battery power.

To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst of IR energy that is picked up by the microchip in the key. The chip responds by sending a unique code the immobiliser of your car. The computer in the car compares the code stored in its memory to the transponder's and If the two codes are identical it will start the engine.

Then leave it off for around 15 minutes then reinsert it and begin the car. This will reset the key system so that it is ready to accept keys once more.

The security light is the vehicle immobiliser's way of telling you that there's an issue with the system. If the light is illuminated and you attempt to start your car, it is a sign that the code that is stored in the ECU does not match the chip inside the key. This can occur in the event that your car's key was replaced with a new one that is not programmed to work with the vehicle, or if an ECU has been swapped incorrectly.

If this is the case then it's time to go to a professional to have the key or the transponder chip properly programmed to your vehicle.

Modern cars come with this system as standard. This makes it really hard to hot-wire the car or use another key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU is then able to determine that it's the right key and that the code isn't compromised. The system won't 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 a wrong fob or key.

The system isn't impervious to attack, but it is. Some thieves have managed to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wiring in a vehicle in order to trick the ECU. However, this is extremely dangerous and requires a lot of experience to carry out the procedure without electrocuting yourself. Plus, a lot of modern car thieves have moved over to more advanced methods such as using specialised apps or Bluetooth to steal the car's information and remotely control it from their mobile.

Car owners will often get warning lights that signal that the immobiliser has gone haywire. This could be due to a variety of reasons, but one of the most common is due to a damaged or dead battery in the key fob. This issue can be resolved by a simple replacement.
