This chip sends a passcode to the car's immobilizer device which can be integrated into the PCM, BCM, the instrument cluster smart junction box, or standalone module. The system examines the code to ensure that it is correct. If it's not it is, the system will shut down parts that are essential to start the vehicle, like the ignition or starter motor.

It functions by sending an audio frequency signal from the key to the immobiliser system inside your car. If the code stored in the computer of the car matches the signal transmitted by the key the immobiliser will then be disarmed and the engine will begin to run.
The key that has the transponder chip is often referred to as"fob" or a smart key because it is more difficult to copy than a traditional mechanical key. Using specific techniques, it is possible to duplicate a standard car key, but not the transponder key. Unlike the central locking element remote of a standard key that relies on battery power the transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits IR energy which is picked up by a microchip inside the key. made my day responds by sending a unique code your car's immobiliser. The car's computer compared the code stored in its memory to the one from the transponder chip and If they are compatible the engine will be able to start.

If the system can't detect a digital serial number from the chip in your key, it will disable the engine immobiliser and prevent the car from getting started.
This car immobiliser system is effective in stopping thieves but sometimes it can be out of in sync with the key or transponder chip. This could be due to interference or the system becoming too sensitive. This may require an adjustment. To do this simply disconnect the battery.

The security light is an immobiliser's way of alerting you to an issue. If the light is on when you try to start your car, it means that the code that is stored in the ECU does not match the chip inside the key. This could happen if you have recently replaced your car's key with one that isn't programmed to the vehicle or if you've had a bad swapped ECU.

Modern cars are equipped with this security system as standard. This makes it very difficult to wire a car or use a different key for starter. The system works by checking the chip in a key fob or key and transmitting a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and that it doesn't have to be compromised code. The system won't allow the car to begin if it does not receive the correct code. Some models even inform the owner when they attempt to use an incorrect fob or key.
The system is not foolproof, however. Some thieves have managed to bypass the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wire in a vehicle in order to trick the ECU. This is a risky technique and requires a lot of knowledge to avoid electrocuting oneself. Modern car thieves are also using more advanced methods, like Bluetooth or specialised apps to steal a car's information and remotely manage it.
Car owners will frequently notice warning lights that signal an immobiliser that has gone out of control. This could be due to various reasons however the most common one is a malfunctioning battery in the keyfob. This problem can be fixed by replacing the battery.
