This chip sends a passcode to the car's immobilizer unit which can be integrated into the PCM, BCM or instrument cluster smart junction box or standalone module. The system examines the code to ensure that it is correct. If it is not then the system will disable parts that are essential to start the vehicle, like the ignition or starter motor.

A small electronic chip, called transponder, is incorporated inside the head portion of your car keys.

Its goal is to prevent your engine from starting if you have an identical key. It works by transmitting an audio signal from the key to the immobiliser system. If the code stored in the car's computer is in line with the signal sent by the key the immobiliser will be removed and the engine will begin to run.
The key with a transponder can also be referred to as a "fob" or a "smart" key, as it is more difficult to copy than mechanical keys. It is possible to duplicate a traditional key but not a transponder key. Unlike the remote central locking element of a conventional key, that relies on battery power the transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder needs to be turned on. The ring emits IR energy that is received by a microchip inside the key. The chip responds by sending a unique code the immobiliser in your car. The car's computer checks the code stored in its memory with the one from the transponder chip and if they match the engine will be able to start.
The immobiliser shuts down the engine if it detects an unauthorised key or transponder. It also blocks all vital components of the car from functioning. Without a functioning engine the vehicle will not be able to move and it will be easy for a criminal to wire the vehicle and then drive off.

Security Light
The immobiliser is powered by a tiny battery that sends an electric signal to the transponder chip in your key.

If the system is unable to identify a digital serial number from the chip inside your key it will disengage the engine immobiliser and prevent the car from getting started.
This system for car immobilisation is an effective in stopping thieves, but it is also possible for it to be out of in sync with the key or transponder chip. This could be due to interference or the system becoming too sensitive. If this is the case it may need to be reset. To do this simply disconnect the battery. Then leave it off for around 15 minutes then reinsert it and begin the car. This will reset the system and allow it to accept the key again.
The security light is an immobiliser's method of warning you of a problem. If the light is illuminated and you try to start your car, it is a sign that the code in the ECU is not compatible with the chip on the key. This can happen if you have recently replaced your car key with a different one that isn't programmed to the vehicle or in the event that you've had a defective swapped ECU.
If this is the case, then it's time to go to a professional and have the transponder or key chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the key due to an issue with the software or an update. To test this, place your key in the ignition and turn it to ON but don't try to start the engine. Keep the key in this position for ten minutes. The security light should turn on, and then go off. If it doesn't, you will need to repeat this process and wait for another 10 minutes. Do this three times and the issue will be resolved.
Programming
The car immobiliser stops the engine from running when the fob or key is not programmed correctly. It is a unique RFID chip that is unable to be duplicated and has a unique digital serial number. The immobiliser will be disconnected in the event that it is unable to recognize the code. It's difficult to beat.
Modern cars have this system as standard. This makes it extremely difficult to hot-wire the car or use a different key as a starter. The system operates by sending a passcode from the key fob to the ECU. The ECU is then able to determine that it's the correct key and that the code isn't compromised. The system won't allow the car to start when it doesn't receive the correct code. Some models even inform the owner when they attempt to use an incorrect fob or key.
However the system isn't foolproof. Some thieves have bypassed the immobiliser with techniques such as '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 method is pretty dangerous and requires a lot of experience to do it without damaging yourself. Plus, a lot of modern car thieves have switched over to more advanced methods like using specialized apps or Bluetooth to hijack the car's data and then remotely control it using their phones.
Car owners often see warning lights that indicate an immobiliser that has gone out of control. This could be due to a variety of reasons, but one of the most common is due to a damaged or dead battery on the key fob. A simple replacement can fix the issue.

This is more difficult to fix and diagnose as it could require an expert locksmith or a dealership.

If you experience any of these problems it is a good idea to consult a local car dealer or garage for assistance.
