It can be integrated into the PCM (power control module) BCM (brake control module) instrument cluster smart junction boxes or standalone modules. The system then validates the code to ensure that it is correct. If it's not then the system will disable parts that are essential to start the vehicle, like the ignition or starter motor.

Transponder Chip
In cars made after 1995, a small electronic chip, referred to as transponder is embedded in the head of your car key. Also known as a 'chip key or a 'transmitter & responder key, it is created to stop the engine from starting if another person has an exact copy of your car key. It works by sending an audio frequency signal from the key to the immobiliser system in your car. If the code on the car's computer matches the signal from the key, it will disarm the immobiliser and allow the engine to begin.
The key with the transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to copy than mechanical keys. Utilizing specific techniques, it is feasible to copy a standard car key however, not the transponder key. In contrast to the remote central locking element of a conventional key that relies on battery power, a transponder chip powered by the 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 a burst of IR energy which is absorbed by the microchip inside the key. The chip responds with an unique code to the immobiliser inside your car. The car's computer compares the code in its memory with that from the transponder chip and if they match, the engine will start.
If the immobiliser detects that an unauthorized transponder or key is being used it will shut down the engine and prevent any of its vital components from working. Without a functioning engine, the vehicle will not be able to move and it could be easy for criminals to connect the vehicle to a hot wire and drive away. This is a powerful deterrent to criminals and is one of the reasons why it's important to have your car key immobiliser repaired as soon as you notice any issue with it. If you don't take this action, the security light on your car will continue blinking, and you won't be able to begin it.
Security Light
The immobiliser uses a small battery to send an electrical signal to the chip that is in your key. This is an anti theft device that stops anyone from driving your car without the right key. If the system can't detect a digital serial number from the chip inside your key, it will disable the engine immobiliser, preventing the car from getting started.
The car immobiliser is a great method to deter thieves, however it can sometimes be out of the sync. This can be caused by interference or the system becoming too sensitive. This could need an adjustment. To do this simply disconnect the battery. Leave it disconnected for about 15 minutes then reinsert it and start the vehicle. This will reset the key system, so 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 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 doesn't match the code stored in the ECU. This could happen if you have recently replaced the car key with a different one that has not been programmed to your vehicle or if you've had a bad swapped ECU.
If this is the case, then it's time to talk to a professional to have the key or the transponder chip properly programmed to your vehicle. There is also the possibility that the system isn't accepting the key due to an issue with the software or an update.

Programming
A car immobiliser prevents the engine of a car from running without a correctly programmed key or fob. It is based on a specific RFID microchip that cannot be duplicated and comes with its own serial number. The immobiliser will disengage if it doesn't recognise the code. That's why it's difficult 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 checking the chip inside the key fob or a key and sending a passcode back to the ECU (electronic control unit). The ECU then knows that it's the correct key and that the code isn't compromised. The system will not allow the car to start if it doesn't have the correct code, and some models will even report back to the owner if someone tries to use an incorrect key or fob.
The system is not impervious to attack, but it is. Some thieves have gotten around the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU to believe that the appropriate fob or key is being used. However, this is quite risky and requires a great deal of experience to do it without electrocuting yourself. In addition, many modern car thieves have moved over to more advanced methods, such as using specialized apps or Bluetooth to hijack a car's data and remotely control it using their phones.
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 causes is a dead or defective battery on the key fob. This problem can be fixed by a simple replacement.
If this does not work it could be because the transponder chip may be defective or the ECU is mismatched. This is more difficult to diagnose and fix as it could require an expert locksmith or a dealership. The car immobiliser could also be damaged if water manages to enter the system or if it is physically removed from its fob or key. If any of these issues occur it's a good idea visit a local garage or car dealer to seek assistance.
