If the code on the car's computer matches that signal sent from the key, it will disable the immobiliser and allow the engine to start.
The key with a transponder can also be referred to as a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. Using special techniques, it is feasible to copy a conventional car key but not the transponder key. In contrast to the remote central locking element of a conventional key that relies on battery power, a transponder chip powered by the infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be turned to the ON position. The ring emits a flash of IR energy that is detected by the microchip within the key. The chip responds by transmitting a unique code to your car's immobiliser. The car's computer compares the code stored in its memory with that from the transponder chip and when they match the engine will be able to start.
The immobiliser shuts down the engine in the event of an unauthorised transponder or key. It will also prevent any vital components of the vehicle from working.

If this is the case it could be necessary to reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and start the vehicle. This will reset the key system so that it is ready to accept your keys again.
The security light is the car immobiliser's way of telling you that there's a problem with the system. If you try to start your car and the light stays on, it means that the chip inside your key isn't compatible with the code stored in the ECU. This can occur in the event that your car's key has been replaced with a new one that is not programmed for the vehicle, or if the ECU has been swapped incorrectly.
If this is the case, then it's time to talk to a professional and have the transponder or key chip properly programmed to your vehicle.

Modern cars come with this system as standard. This makes it extremely difficult to hot-wire the car or use a different key as a starter. The system works by checking the chip in a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU then knows that it's the correct key and that the passcode hasn't been compromised. The system will not allow the car to begin if it does not receive the correct code. Some models even notify the owner when they attempt to use an incorrect fob or key.
The system isn't impervious to attack, but it is. Some thieves have managed to bypass the immobiliser by using methods like hot-wiring. This involves crossing the wrong wires within a vehicle's wiring to fool the ECU into thinking that the correct key or fob is being used. But, this technique is quite risky and requires a great deal of experience to do it without cutting yourself. Modern car thieves are using more advanced methods, like Bluetooth or specialised apps to obtain information about a vehicle and remotely control it remotely.
