It can be integrated into the PCM (power control module), BCM (brake control module) instrument clusters, smart junction boxes, or standalone modules. The system will check the code to ensure it is correct. If the code is not correct, the system disables elements that are crucial to start the car, like the ignition or starter motor.

Transponder Chip
A small electronic chip, also known as transponder, is embedded in the head of your car keys. This technology was introduced in cars manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its function is to stop your engine from starting when you have a duplicate of your key. It works by transmitting radio signals from the key to your immobiliser. 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 with the transponder is also called a "fob" or a "smart" key, as it is more difficult to copy than a mechanical key. It is possible to duplicate a conventional key, but not a transponder one. In contrast to the central locking element remote of a conventional key, which is powered by batteries, a transponder chip powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder needs to be turned to the ON position. The ring emits a burst IR energy that is picked up by a microchip within the key. The chip responds with an individual code to the immobiliser inside your car. The car's computer checks the code stored in its memory with that from the transponder chip and if they match the engine will begin to rev.
If the immobiliser is able to detect an unauthorized transponder or key is being used, it will disable the engine and prevent any of its essential components from working.

If the system can't identify a digital serial number from the chip in your key it will disengage the engine immobiliser and prevent the car from beginning.
This system for car immobilisation is an effective in stopping thieves, but it is also possible for it to become out of 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 could be necessary to reset. To do this, just disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and begin the vehicle. This will reset the system and make it ready to accept your key once more.
The security light is the vehicle immobiliser's method of letting you know that there is an issue with the system. If you try to start the car and the light stays on it indicates that the chip in your key isn't in sync with the code stored in the ECU. This could happen if have recently replaced your car's key with a different one that isn't programmed to your vehicle or if you've had a bad swapped ECU.

If it doesn't, you will need to repeat this process and wait for another 10 minutes. Repeat the process three times and the issue should be solved.
Programming
The car immobiliser stops the engine from running if the fob or key is not properly programmed. It is based on a specific RFID micro-chip that can't be copied and has its own serial number. The immobiliser will stop working when it doesn't recognize the code. It's tough to beat.
Modern cars come with this system as standard. This makes it very difficult to wire a car or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and that it doesn't have to been compromised code. The system will not allow the car to start if it does not receive the correct code. Some models even inform the owner if they attempt to use a wrong fob or key.
The system isn't 100% secure, however. Some thieves have managed to bypass the immobiliser using methods such as 'hot-wiring.' This involves using the wrong wiring in a vehicle to cause a malfunction in the ECU. But, this technique is quite dangerous and requires a lot of knowledge of how to accomplish it without electrocuting yourself. Modern car thieves are employing more sophisticated methods, for instance, Bluetooth or other apps that take over a car's data and remotely manage it remotely.
Car owners are often faced with warning lights that indicate the immobiliser has gone off the rails. This can happen for various reasons, but one of the most frequent is a dead or defective battery on the key fob. The issue can be solved by a simple replacement.
