It can be integrated into the PCM (power control module) BCM (brake control module), instrument cluster smart junction boxes or standalone modules. The system checks the code to make sure it is correct. If the code isn't correct, the system disables components that are crucial to the start of the car, like the ignition or starter motor.

Its function is to prevent the engine from starting when you have an identical key. It works by sending an audio signal from the key to the immobiliser system. If the code in the car's computer matches the signal sent from the key, it will deactivate the immobiliser and allow the engine to start.
The key with the transponder chip is sometimes called"fob" or a smart key because it is much more difficult to duplicate than a traditional mechanical key. Using specific techniques, it is feasible to copy a conventional car key, but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a blast of IR energy that is absorbed by the microchip in the key. The chip responds with an unique code to the immobiliser in your car. The car's computer compares the code stored in its memory here with the transponder's and if the two codes match it will start the engine.

If the system cannot detect an electronic serial number from the chip on your key, it will shut off the engine immobiliser to stop the car from starting.
The car immobiliser system is an an effective way to stop thieves but sometimes it can become out of in sync with the key or transponder chip. This could be due to interference or an immobiliser that is too sensitive. If this car key remote repair near me is the case, it could be necessary to reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and restart the car. This will reset the system and allow it to accept the key again.
The security light is the vehicle immobiliser's way of telling you that there's a problem with the system. If you try to start your car and the light stays on, it indicates that the chip in your key isn't compatible with the code stored in the ECU. This can happen if your car key has been replaced with a new key that's not programmed for the vehicle, or if an ECU was swapped in a wrong manner.
If this is the situation, then you need to go to a professional for assistance and get the the transponder chip properly programmed to your vehicle.

The immobiliser will be disconnected in the event that it is unable to recognize the code. That's why it's difficult to defeat.
Modern cars have this system as standard. This makes it very difficult to connect the car to a hot wire or use a different key as a starter. The system works by analyzing the chip in a key fob or key, and sending a passcode back to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the code isn't compromised. The system won't permit the car to start if the doesn't receive the correct code, and some models will even inform the owner in the event that someone attempts to use a wrong key or fob.
The system isn't completely impervious to attack, but it is. Some thieves have gotten around the immobiliser using methods such as 'hot wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking the proper key or fob is being used. This is a risky method and requires a lot of knowledge to avoid electrocuting oneself. Modern car thieves are also employing more sophisticated methods for instance, Bluetooth or specialised apps to steal a car's information and remotely control it remotely.
Car owners often be greeted by warning lights that indicate an immobiliser malfunctioning. This could be due to a variety of reasons, but the most frequent is due to a damaged or dead battery in the key fob. This issue can be resolved by replacing the battery.
