Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most vehicles are equipped with an immobilizer that prevents car theft. If your vehicle doesn't start after inserting the key fob, it could be an issue with a transponder which isn't sending a security signal to the immobiliser.

Typically the battery for the key fob powers the remote opening and locking systems. The immobiliser is not powered by the key fob battery. Instead, the immobiliser is dependent on the transponder chip on the fob or key. The chip transmits a passcode from the fob or key to the immobilizer unit in the car. It can be integrated into the PCM (power control module) BCM (brake control module) instrument clusters, smart junction boxes, or standalone modules. The system checks the code to make sure that it is correct. If the code is not correct the system will disable components that are crucial to the start of the car, like the ignition motor or starter motor.

It is possible to duplicate a conventional key, but not a transponder key. In contrast to the remote central locking element of a conventional key which is powered by batteries, a transponder chip powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder has to be turned to the ON position. The ring emits a flash of IR energy, which is detected by the microchip within the key. The chip responds by transmitting a unique code to the immobiliser of your car.
