The key fob battery is used to power the remote locking and opening systems. The immobiliser isn't powered by the battery in the key fob.

This chip sends a passcode to the car's immobilizer device which can be integrated into the PCM, BCM, instrument cluster smart junction box or standalone module. The system checks the code to make sure that it is correct. If it is not then the system will disable elements that are crucial to the start of the vehicle, such as the ignition or starter motor.

Transponder Chip

In cars made after 1995, a tiny electronic chip referred to transponder is embedded in the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to stop the engine from starting when you have the same key. It works by sending a radio frequency signal from the key to the immobiliser system in your car. If the code on the car's computer is in line with the signal from the key, it will disarm the immobiliser and allow the engine to start.

The key with a transponder is also referred to as 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 standard key, but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.

To activate the transponder the ignition cylinder has to be in the ON position. The ring emits a flash of IR energy that is picked up by the microchip in the key. The chip then responds with a unique code to the immobiliser of your car. The car's computer checks the code stored in its memory with the one from the transponder chip, and if they match the engine will begin to rev.

If the light is on when you attempt to start your car, it means that the code that is stored in the ECU does not match the chip on the key. This could happen if you have recently replaced the car key with one that isn't programmed to the vehicle, or if you've had a bad swapped ECU.

If this is the case it is recommended to bring your transponder key or chip to a professional to have them properly programmed for your vehicle.

This involves crossing the wrong wiring in an automobile to fool the ECU. However, this method is quite risky and requires a great deal of knowledge of how to accomplish it without electrocuting yourself. Modern car thieves are employing more sophisticated methods like Bluetooth or other specialized apps to obtain information about a vehicle and remotely control it.

Car owners will often get warning lights that indicate that the immobiliser is malfunctioning. This could be due to a variety of reasons, but one of the most frequent causes is a faulty or dead battery on the key fob. This problem can be fixed by an easy replacement.
