Also known as a 'chip key or a 'transmitter and responder key, it is designed to stop the engine from starting if a third party has a copy of your car 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 be deactivated and the engine will begin to run.
The key with the transponder chip is sometimes called a 'fob' or a 'smart' key because it is much more difficult to clone than a traditional mechanical key. It is possible to duplicate a standard key but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip the ignition cylinder must be turned to the ON position. The ring emits a burst IR energy which is picked up by a microchip within the key. The chip then responds with a unique code to the immobiliser of your car. The car's computer compares the code in its memory with the one from the transponder chip and if they get more info match the engine will be able to start.
If the immobiliser detects that an unauthorised transponder or key is being used, it will disable the engine and block any of its vital components from functioning. The car will not move if the engine is not working. It's easy for a criminal to hot-wire it and then drive off.

This is an anti theft device that blocks anyone from starting your vehicle without the proper key. If the system cannot detect a serial number digital from the chip in your key, it will deactivate the engine immobiliser and stop the car from getting started.
The car immobiliser is a fantastic method of deterring thieves, but it can sometimes get out of the sync. This could be due interference or an immobiliser that is too sensitive. If this is the case, it might need to be reset. To do this, disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and begin the vehicle. This will reset the key system, so that it is ready to accept your keys once again.
The security light is the car immobiliser's way of telling you that there's an issue with the system. If you try to start your car and the light stays on it means that the chip in your key isn't compatible with the code that is stored in the ECU. This could happen if your car key was replaced with a new key that's not compatible with the vehicle, or if an ECU has been swapped incorrectly.
If this is the case you should take your key or transponder chip to a professional to get them correctly programmed for the vehicle you are driving.

The immobiliser will disconnect in the event that it is unable to recognize the code. That's why it's difficult to beat.
Modern cars are fitted with this security system by default. This makes it very difficult to connect the car to a hot wire or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. here The ECU will then verify that it's the right key and that the code isn't compromised. The system won't allow the car to begin when it doesn't receive the correct code. Some models even notify the owner when they attempt to use an unapproved fob or key.
The system is not 100% secure, however. Some thieves have gotten around the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wire in a vehicle to fool the ECU. This is a risky technique and requires extensive knowledge to avoid electrocuting oneself. Modern car thieves are using more advanced methods, for instance, Bluetooth or other apps that steal a car's information and remotely manage it remotely.
Car owners will often get warning lights that signal that the immobiliser is malfunctioning. This could be due to a variety of reasons, but the most common is a faulty or dead battery in the key fob. The issue can be solved by replacing the battery.
If this does not work, it could be that the transponder chip is defective or the ECU is not compatible. This is harder to determine and fix since it may require an expert locksmith or a dealership.
