The chip transmits a code from the fob or key to the immobilizer unit in the car, which could 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 it's not, the system will disable components crucial to starting the vehicle, like the ignition or starter motor.

It is also known as a "chip key" or a "transmitter-responder" key. Its purpose is to stop the engine from starting when another person has an identical key. It works by transmitting an audio signal from the key to your immobiliser. If the code on the car's computer matches that signal transmitted by the key, it will disable the immobiliser and allow the engine to begin.
The key that has the transponder chip is often referred to as"fob" or a "smart" key due to the fact that it is more difficult to clone than a conventional mechanical key. It is possible to duplicate a standard 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 powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder must be turned on. The ring emits a flash of IR energy which is detected by the microchip in the key. The chip then sends a unique code to the immobiliser of your car. The car's computer checks the code in its memory with that from the transponder chip and If they are compatible, the engine will start.
The immobiliser will disable the engine if it detects an unauthorised transponder or key. It also stops all vital parts of the car from working.

The security light is a way of warning you of a problem. If the light is on and you try to start your car, it is a sign that the code stored in the ECU is not compatible with the chip in the key. This could happen if have recently replaced the car key with one that was not programmed to the vehicle or if you've had a bad swapped ECU.
If this is the case then you need to go to a professional and have the the transponder chip properly programmed to your vehicle.

The system works by analyzing the chip inside a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU will then verify that it's the right 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. Certain models will even notify the owner if they try to use an incorrect fob or key.
However the system isn't completely secure. Some thieves have been able to get around the immobiliser using techniques like 'hot-wiring'. This involves using the wrong wiring in a vehicle in order to fool the ECU. But, this technique is quite dangerous and requires a lot of knowledge of how to do it without cutting yourself. Modern car thieves are also employing more sophisticated methods for instance, Bluetooth or other apps that take over a car's data and remotely control it remotely.
