The system examines the code to ensure it is correct. If the code isn't correct it will disable the components that are crucial to starting the car, such as the starter motor or ignition.

The security light is an immobiliser's way of alerting you to a problem. If you try to start the car and the light stays on it means that the chip in your key doesn't match the code that is stored in the ECU. This can occur when your car's key was replaced with a new one that is not compatible with the vehicle, or if the ECU has been swapped incorrectly.

However, this method is quite risky and requires a lot of knowledge of how to carry out the procedure without cutting yourself. Modern car thieves are using more advanced methods, such as Bluetooth or other specialized apps to take over a car's data and remotely control it remotely.
