Its purpose is to prevent your engine from starting when you have the same key. It functions by sending an audio frequency signal from the key to the immobiliser system inside your car. If the code in the car's computer is in line with the signal from the key, it will disarm the immobiliser and allow the engine to begin.

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

To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy that is received by a microchip in the key. The chip responds with a unique code to the immobiliser of your car. The car's computer compared the code stored in its memory with that from the transponder chip and when they match, the engine will start.

If the immobiliser is able to detect an unauthorized transponder or key is being used, it will disable the engine and prevent the essential components from functioning.

The car immobiliser system is an effective in stopping thieves, however it can be out of connection with the key or the transponder chip. This can be caused by interference or the system being too sensitive. This may require a reset. To do this, disconnect the battery. Then leave it off for around 15 minutes before reinstalling it and begin the car. This will reset the key system to ensure that it is ready to accept your keys again.

The security light is the vehicle immobiliser's method of letting you know that there's an issue with the system. If the light is on and you try to start your car, it means that the code in the ECU is not compatible with the chip inside the key. This could happen if you have recently replaced your car's key with one that was not programmed to your vehicle or if you've had a bad swapped ECU.

If this is the case you should take your key or transponder chip to a professional to get them properly programmed for your vehicle. It's possible that your system won't accept the key because of a software update or bug. To test this, place your key in the ignition and switch it to ON but don't attempt to start the engine.

It's difficult to beat.

Modern cars come with this system as standard. This makes it very difficult to wire a car or use a different key for starter. The system works by checking the chip inside the key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU will then verify that it's the right key and that the passcode hasn't been compromised. The system won't allow the car to start if it does not receive the correct code, and some models will even inform the owner if someone tries to use an unapproved fob or key.

The system isn't completely impervious to attack, but it is. Certain thieves have been able to bypass the immobiliser by using techniques like 'hot-wiring'. This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU to believe that the proper key or fob is being used. However, this method is quite dangerous and requires a lot of knowledge of how to accomplish it without damaging yourself. Plus, a lot of modern car thieves have switched over to more advanced methods such as using specialised apps or Bluetooth to steal a car's data and remotely control it via their phones.

Car owners will often get warning lights that indicate the immobiliser has gone haywire. This could be due to many reasons, but the most common one is a faulty battery in the keyfob. The issue can be solved by a simple replacement.
