It is possible to duplicate a standard key but not a transponder one. Contrary to the central locking element remote of a conventional key, which is powered by batteries the transponder chip is powered by the infrared (IR) signal that is 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 burst of IR energy, which is absorbed by the microchip inside the key. The chip then sends an unique code to the immobiliser of your car. The car's computer checks the code stored in its memory with that from the transponder chip and if they match, the engine will start.

If the immobiliser is able to detect an unauthorised transponder or key is being used it will shut down the engine and block the essential components from functioning.

If the system cannot detect a digital serial from the chip in your key, it will shut off the engine immobiliser to stop the car starting.

This car immobiliser system is effective in stopping thieves, but it is also possible for it to be out of connection with the key or the transponder chip. This can be due to interference or the system becoming too sensitive. This could require an adjustment. To do this, disconnect the battery. Then leave it off for around 15 minutes then reinsert it and begin the vehicle. This will reset the key system so that it is ready to accept your keys once again.

The security light is a way of alerting you to the presence of a problem. If the light is on and you attempt to start your car, it means that the code that is stored in the ECU does not match the chip in the key.

Programming

A car immobiliser prevents the car's engine from operating without a key that is programmed correctly or fob. It uses a special RFID chip that is unable to be duplicated and has a unique digital serial number. The immobiliser will disconnect when it doesn't recognize the code. It's hard to beat.

Modern cars are equipped with this security system as standard. This makes it difficult to hot-wire a vehicle or utilize a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU knows it's the correct key and that there hasn't been a compromise in the code. The system won't allow the car to begin when it doesn't receive the correct code. Some models even notify the owner if they attempt to use an unapproved fob or key.

This involves crossing the wrong wire in an automobile to fool the ECU. However, this is extremely risky and requires a great deal of experience in order to do it without damaging yourself. In addition, many modern car thieves have switched to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's information and remotely control it using their phone.

Car owners will often get warning lights that indicate the immobiliser has gone off the rails. It can occur for a variety of reasons, but one of the most frequent causes is due to a damaged or dead battery on the key fob. A simple repair should resolve this issue.

However, a car immobiliser can also be damaged by water ingress or even physically being removed from the fob or key. If any of these problems occur, it's a good idea visit a local garage or car dealer for assistance.
