The immobiliser is powered by a transponder that is located in the key, fob or instrument cluster. The chip transmits a code from the fob or key to the immobilizer module of the car, which can be integrated into the PCM (power control module), BCM (brake control module), instrument clusters, smart junction boxes, or standalone modules. The system then checks the code to make sure it is correct. If it is not, the system will disable parts that are essential to start the vehicle, like the starter motor or ignition. The car will be impossible to start if the driver doesn't have the right key.
Since its inception the immobiliser has proved to be an extremely effective tool in decreasing car theft.

Its function is to prevent the engine from starting when another person has a duplicate of your key. It works by sending an audio signal from the key to your immobiliser system. If the code stored in the computer of the car matches the signal sent by the key the immobiliser will then be removed and the engine will start.
The key with the transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. With the help of specific techniques, it is feasible to copy a conventional car key, but not the transponder key. Unlike the central locking element remote of a conventional key, which uses battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder needs to be turned on. The ring emits a burst IR energy that is picked up by a microchip inside the key. The chip responds by sending a unique code to the immobiliser of your car. The computer in the car examines the code in its memory with the one on the transponder and check here when the two codes match it will start the engine.
If the immobiliser is able to detect an unauthorised transponder, key or other device is in use, it will disable the engine and block any of its essential components from functioning.

This system for car immobilisation is an effective in stopping thieves, however it can be out of in sync with the key or transponder chip. This can be due to interference or the system being too sensitive. If this is the case, it may need to be reset. To do this, simply disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the key system to ensure that it is ready to accept keys once more.
The security light is the car immobiliser's way of telling you that there's an issue with the system. If you attempt to start the car but the light stays on, it means that the chip in your key isn't in sync with the code that is stored in the ECU. This can occur when your car's key has been replaced with an alternative key that is not programmed for the vehicle, or if an ECU was not swapped correctly.
If this is the case you should take your key or transponder chip to a professional to have them properly programmed for your vehicle.

Programming

The immobiliser will be disengaged in the event that it doesn't recognize the code. It's hard to beat.
Modern cars are fitted with this security system in the standard configuration. This makes it extremely difficult to hot-wire the car or use a different key as a starter. The system works by analyzing the chip inside a key fob or key, and sending a passcode back to the get more info ECU (electronic control unit). The ECU recognizes that it is the correct key and that there hasn't be compromised code. The system will not allow the car to start when it doesn't receive the correct code. Some models even notify the owner if they attempt get more info to use an unapproved fob or key.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser with techniques such as 'hot-wiring.' This involves crossing the wrong wire in an automobile to trick the ECU. However, this method is pretty risky and requires a lot of knowledge of how to carry out the procedure without cutting yourself. In addition, many modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to take over the car's data and then remotely control it using their phones.
Car owners are often faced with warning lights that indicate the immobiliser has gone haywire. This can occur for many reasons, but the most common one is a faulty battery in the keyfob. A simple replacement should fix this problem.
