The chip transmits a passcode from the key or fob to the immobilizer unit of the car, which can be integrated into the PCM (power control module) or BCM (brake control module for brake control), instrument cluster, smart junction boxes, or standalone modules. The system then validates the code to ensure that it is correct. If the code is not correct the system will disable components that are essential to the start of the car, like the starter motor or ignition.

If the issue persists, then there might be other reasons for the car's irregular behavior, such as electrical issues or a wiring problem.

It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting when you have the same key. It works by transmitting an audio signal from the key to the immobiliser system. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be disarmed and the engine will be able to start.
The key with the transponder chip is sometimes called a 'fob' or a 'smart' key because it is more difficult to copy than a traditional mechanical key. It is possible to duplicate a standard key but not a transponder one. In contrast to the central locking element remote of a conventional key that relies on battery power, a transponder chip powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits IR energy that is received by a microchip in the key. The chip then sends a unique code to the immobiliser inside your car. The computer in the car analyzes the code stored in its memory with the transponder's and when the two codes match it will begin the engine.
The immobiliser will shut down the engine when it detects an unauthorised key or transponder. It also blocks any essential parts of the car from functioning.

This is an anti-theft device that stops anyone from opening your vehicle without the proper key. If the system is unable to identify a digital serial number from the chip in your key, it will disable the engine immobiliser and prevent the car from beginning.
The car immobiliser is a fantastic way to deter thieves, but it can occasionally be out of the sync. This could be due to interference or the system is too sensitive. If this is the situation, it might need to be reset. To do this, simply disconnect the battery. After 15 minutes, reinstall the battery and then restart the car. This will reset the key system to ensure that it is ready to accept keys once more.
The security light is an immobiliser's way of warning you of the presence of a problem. If the light is on and you try to start your car, it is a sign that the code that is stored in the ECU is not compatible with the chip in the key. This could happen if you have recently replaced the car key with another that has not been programmed to the vehicle or when you've had a damaged swapped ECU.
If this is the case you should bring your transponder key or chip to a professional to have them properly programmed for your car.

Modern cars are equipped with this security system as standard. This makes it very difficult to hot-wire the car or use another key remote key repair near me for starter. The system works by sending a code from the key fob to the ECU. The ECU is then able to determine that it's the correct key and that the passcode isn't compromised. The system will not allow the car to start in the event that it does not receive the correct code. Certain models will even notify the owner if they try to use an unapproved fob or key.
However, the system is not impervious to theft. Some thieves have been able to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wires in a vehicle's wiring to fool the ECU to believe that the correct key or fob is being used. This method is risky and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are employing more sophisticated methods like Bluetooth or specialised apps to steal a car's information and remotely control it.
Car owners will often get warning lights that indicate that the immobiliser has gone off the rails. This could be due to a variety of reasons but the most frequent reason is a defective battery in the keyfob. The issue can be solved by a simple replacement.
