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. The system examines the code to make sure it's correct. If it's not it is, the system will shut down parts that are essential to start the vehicle, such as the ignition or starter motor.

Its goal is to prevent the engine from starting when another person has a duplicate of your key. It works by transmitting an audio 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 deactivated and the engine will start.
The key with the transponder chip is often referred to as a 'fob' or a "smart" key because it is more difficult to duplicate than a traditional mechanical key. With the help of special techniques, it is possible to copy a standard car key, but not transponder keys. Transponder chips are powered by an infrared signal not battery power.
To activate more info the transponder chip the ignition cylinder must be turned on. The ring emits a burst IR energy which is detected by a microchip in the key. The chip responds with an individual code to the immobiliser of your car. The car's computer compares the code stored in its memory with the one on the transponder and If the two codes are identical, it will start the engine.

This system for car immobilisation is an an effective way to stop thieves but sometimes it can become out of connection with the key or the transponder chip. This can be caused by 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. After 15 minutes, read more you can reinstall the battery and then restart the car. This will reset the key system, so that it is ready to accept keys once more.
The security light is an immobiliser's method of warning you of the presence of a problem. If you try to start your car and the light stays on it indicates that the chip in your key doesn't match the code that is stored in the ECU.

Modern cars come with this security system by default. This makes it very difficult to hot-wire a vehicle or utilize a different key for starter. The system works by analyzing the chip in a key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU then knows that it's the right key and that the passcode isn't compromised. The system won't allow the car to start if it doesn't have the correct code, and some models will even inform the owner if a person tries to use a wrong fob or key.
The system isn't foolproof, however. Some thieves have gotten around the immobiliser using methods such as 'hot-wiring.'
