Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip called transponder is embedded in the head of your car key. It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting if you have a duplicate of your key. It works by sending an audio frequency signal from the key to the immobiliser system in your car. If the code stored in the car's computer matches that signal transmitted by the key, it will deactivate the immobiliser and allow the engine to begin.
The key that has the transponder chip can be referred to as a 'fob' or a "smart" key because it is much more difficult to clone than a traditional mechanical key. Using special techniques, it is possible to duplicate a standard car key but not a transponder key. In contrast to the remote central locking element of a conventional key that relies on battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder the ignition cylinder has to be in the ON position. The ring emits a burst of IR energy, which is detected by the microchip within the key. The chip then sends a unique code to the immobiliser inside your car. The car's computer checks the code stored in its memory with the one from the transponder chip and if they match the engine will begin to rev.
If the immobiliser detects that an unauthorised transponder or key is in use it will shut down the engine and block any of its essential components from functioning.

If the system is not able to recognize a digital serial from the chip on your key, it will disable the engine immobiliser, which will stop the car starting.
The car immobiliser is an excellent method of deterring thieves, but it can sometimes get out of sync. This can be caused by interference or the system becoming too sensitive. If this is the case, it could be necessary to reset. To do this simply disconnect the battery. After 15 minutes, you can reinstall the battery and then restart the car. This will reset the key system to ensure that it is ready to accept keys once more.
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 vehicle, it indicates that the code in the ECU does not match the chip in the key. This could happen if have recently replaced your car's key with one that was not programmed to the vehicle or when you've had a damaged swapped ECU.

Let the key remain in this position for ten minutes. The security light should come on, then go off. If it doesn't, you will need to repeat this process and wait for another 10 minutes. This should solve the problem If you repeat the procedure three times.
Programming
The car immobiliser stops the engine from running when the fob or key is not programmed correctly. It makes use of a unique RFID microchip that isn't able to be duplicated and has its own digital serial number. The immobiliser will be disconnected if it does not recognise the code. It's hard to beat.
Modern cars come with this security system by default. This makes it very difficult to hot-wire the car or use a different key as a starter. The system works by checking the chip inside a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that it doesn't have to been compromised code. The system will not allow the car to start if the doesn't have the correct code. Some models will even report back to the owner if a person tries to use an unapproved key or fob.
The system isn't completely impervious to attack, but it is. Some thieves have gotten around the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wiring in an automobile to fool the ECU. This is a risky technique and requires a lot of experience to avoid electrocuting oneself. Plus, a lot of modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to take over a car's data and remotely control it via their phones.
Owners of cars will often see warning lights that indicate an immobiliser malfunctioning. It can occur for a variety of reasons, but the most frequent causes is a faulty or dead battery in the key fob. This issue can be resolved by replacing the battery.
