This chip sends a passcode to the car's immobilizer unit that can be integrated into the PCM, BCM, instrument cluster smart junction box or standalone module. The system then validates the code to ensure that it is correct. If the code isn't correct the system will disable elements that are crucial to the start of the car, like 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 sending radio signals from the key to your immobiliser. If the code stored in the car's computer matches the signal sent by the key the immobiliser will then be removed and the engine will be able to start.
The key with a transponder is also called a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. With the help of specific methods, it is possible to copy a standard car key but not transponder keys. Contrary to the central locking element remote of a conventional key, which uses battery power, a transponder chip is powered by the infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be turned to the ON position. The ring emits a flash of IR energy that is absorbed by the 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 stored in its memory to the one on the transponder and if the two codes match, it will start the engine.
If the immobiliser detects an unauthorised transponder, key or other device is being used, it will disable the engine and stop any of its essential components from working.

If this is the case, it might need to be reset. To do this simply disconnect the battery. Then leave it off for around 15 minutes, then insert it and start the vehicle. This will reset the key system so that it is ready to accept your keys again.
The security light is the vehicle immobiliser's way of telling you that there's an issue with the system. If the light is illuminated and you attempt to start your car, it means that the code that is stored in the ECU does not match the chip in the key. This can happen when your car's key was replaced with a new one get more info that is not programmed to work with the vehicle, or if the ECU was not swapped correctly.

That's why it's difficult to defeat.
Modern cars have this system as standard. This makes it read more extremely difficult to hot-wire a vehicle or use 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 will then verify that it's the correct key and that the passcode isn't compromised. The system will not allow the car to begin when it doesn't receive the correct code. Certain models will even notify the owner if they attempt to use an incorrect fob or key.

This method is risky and requires extensive experience to avoid electrocuting oneself. Modern car thieves are also using more advanced methods, like Bluetooth or other specialized apps to take over a car's data and remotely manage it.
Car owners will often get warning lights that signal that the immobiliser has gone off the rails. It can happen for many reasons but the most frequent one is a malfunctioning battery in the keyfob. This issue can be resolved by a simple replacement.
