In vehicles manufactured after 1995, a tiny electronic chip called transponder is embedded in the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its function is to prevent the engine from starting when someone else has a duplicate of your key. It works by sending radio signals from the key to the immobiliser system. If the code in the car's computer matches that signal sent from the key, it will deactivate the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip can be referred to as"fob" or a 'smart' key due to the fact that it is more difficult to duplicate than a traditional mechanical key. With the help of special methods, it is possible to copy a conventional 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 an infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder chip the ignition cylinder needs to be turned to the ON position. The ring emits a blast of IR energy, which is detected by the microchip in the key. The chip responds with a unique code to the immobiliser of your car. The car's computer compares the code in its memory with that from the transponder chip, and if they match the engine will begin to rev.
If the immobiliser is able to detect an unauthorized transponder or key is in use it will shut down the engine and prevent any of its essential components from functioning.

If the system cannot identify a digital serial number from the chip inside your key, it will disable the engine immobiliser, preventing the car from starting.
This system for car immobilisation is an effective in stopping thieves, but it is also possible for it to get out of connection with the key or the transponder chip. This can be caused by interference or the system being too sensitive. This could need the system to be reset. To do this simply disconnect the battery. Then leave it off for around 15 minutes then reinsert 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 an immobiliser's way of warning you of an issue. If you try to start your car and the light is solid on it means that the chip inside your key doesn't match the code that is stored in the ECU. This could happen if you have recently replaced your car's key with another that isn't programmed to the vehicle, or if you've had a bad swapped ECU.

Programming
An immobiliser for cars prevents the car's engine from operating without a key that is programmed correctly or fob. It uses a special RFID micro-chip that can't be duplicated and has its own serial number. The immobiliser will stop working when it doesn't recognize the code. It's tough to beat.
Modern cars are equipped with this security system by default. This makes it extremely difficult to connect the car to a hot wire or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU will then verify that it's the right key and that the passcode isn't compromised. The system won't allow the vehicle to start if it doesn't have the correct code, and some models will even inform the owner if someone tries to use an incorrect fob or key.
However, the system is not impervious to theft. Certain thieves have been able to bypass the immobiliser using methods like hot-wiring. This involves crossing the wrong wire in a vehicle to fool the ECU. This method is risky and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are also using more advanced methods, like Bluetooth or other apps that take over a car's data and remotely manage it.
Car owners are often faced with warning lights that indicate the immobiliser has gone off the rails. This could be due to various reasons, but the most common one is a malfunctioning battery in the keyfob. The issue can be solved by replacing the battery.
