Transponder Chip
In vehicles manufactured after 1995, a small electronic chip referred to transponder is integrated into the head of your car key. It is also referred to a "chip key" or a "transmitter-responder" key. Its function is to prevent your engine from starting if someone else has a duplicate of your key. It functions by sending the radio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer is in line with the signal transmitted by the key, it will disarm the immobiliser and allow the engine to start.
The key with a transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to copy than a mechanical key. It is possible to duplicate a standard key but not a transponder key. Unlike the central locking element remote of a conventional key, which is powered by batteries, a transponder chip powered by the 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 has to be turned to the ON position. The ring emits a blast of IR energy, which is picked up by the microchip inside 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 to the one on the transponder and when the two codes match it will begin the engine.
The immobiliser will disable the engine if it detects an unauthorised key or transponder. It also stops any essential parts of the car from functioning.

If the system is not able to recognize a digital serial from the chip in your key, it will shut off the engine immobiliser to stop the car from starting.
The car immobiliser system is an an effective way to stop thieves but sometimes it can become out of in sync with the key or transponder chip. This could be due to interference or a system that is too sensitive. This may need an adjustment. To do this simply disconnect the battery.

The security light is a way of alerting you to a problem. If the light is on when you attempt to start your vehicle, it indicates that the code stored in the ECU is not compatible with the chip inside the key. This could happen when your car's key has been replaced with a new key that's not programmed for the vehicle, or when an ECU has been swapped incorrectly.

The system operates by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and that it doesn't have to be compromised code. The system won't allow the car to begin in the event that it does not receive the correct code. Certain models will even notify the owner when they attempt to use a wrong fob or key.
The system is not 100% secure, however. Some thieves have bypassed the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU into thinking that the correct key or fob is being used. However, this method is pretty risky and requires a lot of knowledge of how to carry out the procedure without damaging yourself. In addition, many modern car thieves have shifted to more sophisticated methods such as using specialised apps or Bluetooth to steal the car's information and remotely control it from their phone.
