Transponder Chip
A small electronic chip, also known as transponder, is embedded inside the head portion of your car keys. This technology was first introduced in cars manufactured after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its purpose is to stop the engine from starting when you have a duplicate of your key. It functions by sending an audio frequency signal from the key to the immobiliser system of your car. If the code stored in the computer of the car matches the signal sent by the key, the immobiliser will be deactivated and the engine will start.
The key with the transponder chip can be referred to as a 'fob' or a smart key because it is much more difficult to copy 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 not battery power.
To activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a blast of IR energy, which is absorbed by the microchip in the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer examines the code in its memory with the one on the transponder and if the two codes match it will start the engine.
If the immobiliser detects an unauthorised transponder or key is in use it will shut down the engine and block the essential components from working. The car will not move when the engine isn't working. It is easy for criminals to wire it and then drive off.

The security light is an immobiliser's way of warning you of an issue. If the light is on and you attempt to start your car, it means that the code stored in the ECU is not compatible with the chip in the key. This can happen if you have recently replaced your car key with a different one that isn't programmed to the vehicle or in the event that you've had a defective swapped ECU.

Modern cars are fitted with this security system by default. This makes it difficult to hot-wire a car or use a different key as a starter. The system works by checking the chip inside the key fob or key and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the code hasn't been compromised. The system won't allow the car to start if the doesn't have the correct code, and some models will even notify the owner if a person tries to use an unapproved fob or key.
The system isn't impervious to attack, but it is. Some thieves have gotten around the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wiring in a vehicle in order to trick the ECU. However, this is quite dangerous and requires a lot of experience in order to accomplish it without electrocuting yourself. Modern car thieves are employing more sophisticated methods, such as Bluetooth or specialised apps to steal a car's information and remotely control it remotely.
