This chip transmits a passcode from the fob or key to the immobilizer unit in the car, which can be integrated into the PCM (power control module) or BCM (brake control module for brake control), instrument clusters smart junction boxes or standalone modules.

Its function is to prevent your engine from starting when another person has a duplicate of your key.

The key with a transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than mechanical keys. It is possible to duplicate a conventional key but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.

To activate the transponder chip, the ignition cylinder has to be turned on. The ring emits a burst of IR energy which is absorbed by the microchip within the key. The chip then responds with an individual code to the immobiliser of your car. The car's computer compares the code stored in its memory with the one from the transponder chip and when they match the engine will begin to rev.

The immobiliser shuts down the engine if it detects an unauthorised key or transponder. It also blocks any essential components of the car from working. The car won't move when the engine isn't functioning. It would be easy for a criminal hot-wire it and then drive off.

This could be due to interference or an immobiliser that is too sensitive. This may require the system to be reset. To do this, simply disconnect the battery. Leave it disconnected for about 15 minutes, then insert it and begin the car. This will reset the key system so that it is ready to accept your keys again.

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 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 the car key with another that isn't programmed to the vehicle or when you've had a damaged swapped ECU.

If this is the case then it's time to go to a professional and have the transponder or key chip properly programmed to your vehicle. There is also the possibility that the system isn't accepting the key because of an issue with the software or an update.

The system works by analyzing the chip inside the key fob or car key immobiliser repair key and sending a passcode to the ECU (electronic control unit). The ECU knows it's the correct key and that it doesn't have to been a compromise in the code. The system will not allow the car to start in the event that it does not receive the correct code. Some models even inform the owner if they attempt to use an incorrect fob or key.

The system isn't foolproof, however. Some thieves have gotten around the immobiliser by using techniques like 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking that the proper key or fob is being used. This is a risky technique and requires extensive experience to avoid electrocuting oneself. In addition, many modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to steal the car's information and remotely control it from their phones.

Car owners will frequently see warning lights that indicate an immobiliser malfunctioning. This can occur for various reasons, but the most common reason is a defective battery in the keyfob. This issue can be resolved by an easy replacement.
