Transponder Chip
A tiny electronic chip, called transponder, is embedded in the head of your car keys. This technology was introduced in vehicles manufactured after 1995. Also referred to as a 'chip key or a 'transmitter and responder key, it is designed to stop the engine from starting if a third party has an exact copy of your car key. It works by sending radio signals from the key to your immobiliser. If the code on the car's computer matches that signal transmitted by the key, it will disable the immobiliser and allow the engine to start.
The key that has the transponder chip is sometimes called a 'fob' or a "smart" key because it is more difficult to copy than a conventional mechanical key. Utilizing specific techniques, it is possible to duplicate a standard car key however, not the transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip the ignition cylinder must be switched to ON. The ring emits a blast of IR energy, which is picked up by the microchip in the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer compares the code in its memory to the one from the transponder chip, and if they match, the engine will start.
If g28carkeys that an unauthorised transponder or key is being used, it will disable the engine and block any of its essential components from working. The car will not move when the engine isn't working. It is easy for a criminal hot-wire it to drive away.

If you don't fix it, the security light in your car will keep flashing and it will be impossible to start your engine.
Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip in your key. This is an anti theft device that prevents anyone from driving your vehicle without the right key. If the system cannot detect a digital serial number from the chip on your key, it will disable the engine immobiliser to stop the car from starting.
The car immobiliser is a great way to deter thieves, but it could sometimes get out of in sync. This can be due to interference or an immobiliser that is too sensitive. This could need an adjustment. To do this, disconnect the battery. It should be left disconnected for around 15 minutes, then insert it and start the vehicle. 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 method of letting you know that there's an issue with the system. If the light is on when you attempt to start your vehicle, it indicates that the code stored in the ECU does not match the chip in the key. This can happen if you have recently replaced your car's key with one that has not been programmed to the vehicle, or if you've had a bad swapped ECU.
If this is the situation, then it's time to go to a professional and have the transponder or key chip properly programmed to your vehicle.

Programming

Some models even notify the owner if they try to use an unapproved fob or key.
The system is not impervious to attack, but it is. Certain thieves have been able to bypass the immobiliser using methods like hot-wiring. This involves crossing the wrong wires within a vehicle's wiring to fool the ECU into thinking the appropriate fob or key is being used. But, this technique is quite risky and requires a lot of experience to do it without cutting yourself. Modern car thieves are also employing more sophisticated methods for instance, Bluetooth or other apps that obtain information about a vehicle and remotely control it.
