It can be integrated into the PCM (power control module) or BCM (brake control module for brake control) instrument clusters smart junction boxes or standalone modules.

Transponder Chip

It is also referred to as a "chip key" or a "transmitter-responder" key. Its purpose is to stop your engine from starting when another person has the same key. It works by sending the radio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer is in line with the signal sent by the key the immobiliser will then be removed and the engine will start.
The key that has a transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to duplicate than mechanical keys. It is possible to duplicate a conventional key, but not a transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip the ignition cylinder has to be turned to the ON position. broken key repair The ring emits IR energy which is detected by a microchip within the key. The chip then responds with an unique code to the immobiliser of your car. The car's computer compares the code in its memory with that from the transponder chip, and If they are compatible, the engine will start.
If the immobiliser detects that an unauthorised transponder or key is being used, it will disable the engine and block any of its essential components from functioning. Without a functioning engine the vehicle will not be able to move, and it could be easy for a criminal to hot-wire the vehicle and drive away.

If you don't do this, the security light on your car will continue to flash and it will be difficult for you to start your engine.
Security Light
The immobiliser utilizes a small battery to send an electrical signal to the chip in your key. This device is designed to prevent anyone from starting their car without the correct keys. If the system is unable to detect a serial number digital from the chip inside your key, it will deactivate the engine immobiliser, preventing the car from beginning.
The car immobiliser system is an effective in stopping thieves, however it can be out of sync with the key or transponder chip. This could be due to interference or the system being too sensitive. If this is the case it could be necessary to reset. To do this, just disconnect the battery. After 15 minutes, reinstall the battery and then restart the car. This will reset the system and allow it to accept the key again.
The security light is an immobiliser's way of warning you of the presence of a problem. If you try to start the car and the light is solid on it indicates that the chip inside your key isn't in sync with the code that is stored in the ECU. This can happen in the event that your car's key has been replaced with a new one that is not programmed to work with the vehicle, or if the ECU was swapped in a wrong manner.
If this is the situation you should bring your transponder key or chip to a professional to have them correctly programmed for the vehicle you are driving.

It's hard to beat.
Modern cars come with this system as standard. This makes it really hard to wire the car hot or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU will then verify 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 unapproved fob or key.
However the system isn't impervious to theft. Some thieves have bypassed the immobiliser by using techniques such as 'hot wiring.' This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU into thinking that the appropriate fob or key is being used. However, this is extremely risky and requires a great deal of knowledge of how to do it without cutting yourself. Modern car thieves are also employing more sophisticated methods, such as Bluetooth or other apps that take over a car's data and remotely manage it.
Car owners will frequently see warning lights that indicate an immobiliser malfunctioning. This could be due to a variety of reasons, but one of the most frequent is a faulty or dead battery on the key fob. A simple replacement should fix the issue.

If you experience any of these problems it is a great idea to visit an auto dealer in your area or garage for assistance.
