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

Transponder Chip
A tiny electronic chip, referred to as transponder, is incorporated into the head portion of your car keys. This technology was first introduced in cars made after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its function is to prevent your engine from starting if someone else has a duplicate of your key. It functions by sending an audio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer matches the signal sent from the key, it will disable the immobiliser and allow the engine to start.
The key that has a transponder is also called a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. It is possible to duplicate a conventional key but not a transponder key. Contrary to the central locking element remote of a conventional key, which is powered by batteries, a transponder chip is powered by an infrared (IR) signal 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 blast of IR energy that is detected by the microchip in the key. The chip then sends an individual 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 an unauthorised transponder, key or other device is being used it will shut down the engine and block any of its vital components from working. Without a functioning engine, the car will not be able to move and it will be easy for a criminal to wire the vehicle and then drive off.

This will reset the key system to ensure that it is ready to accept your keys again.
The security light is a way of warning you of a problem. If the light is on and you attempt to start your vehicle, it indicates that the code that is stored in the ECU is not compatible with the chip in the key. This can happen when your car's key was replaced with a new one that is not compatible with the vehicle, or if an ECU was not swapped correctly.
If this is the situation you should take your key or transponder chip to a professional to have them correctly programmed for the vehicle you are driving.

Programming

Modern cars have this system as standard. This makes it very difficult to hot-wire a car or use a different key for starter. The system works by checking the chip in the key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and that it doesn't have to be compromised code. The system will not allow the car to begin in the event that it does not receive the correct code. Some models even inform the owner if they attempt to use an unapproved fob or key.
The system isn't foolproof, however. Some thieves have managed to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wires through the wiring of a vehicle to trick the ECU into thinking the proper key or fob is being used. However, this is pretty dangerous and requires a lot of experience in order to accomplish it without damaging yourself. Modern car thieves are using more advanced methods, for instance, Bluetooth or specialised apps to steal a car's information and remotely control it.
Owners of cars will often be greeted by warning lights that indicate an immobiliser gone haywire. It can occur for a variety of reasons, but the most frequent is a faulty or dead battery in the key fob. A simple replacement should fix the issue.
