The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your car.

A circuit within the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal is received by the chip which sends a signal to the vehicle.

There are a few different ways to program a key fob based on the vehicle's make and model. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one. When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle with which it is linked. The receiver compares this information to the 'allowed' signals stored on the fob and either opens or locks the door. If the information doesn't match, the car will not be allowed to drive. When a car is connected with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they look identical. This protects the integrity of the computer system of the car and blocks unauthorised key fobs from taking control over it. Most newer car dealerships will only accept cars with original fobs or genuine replacements sold by the manufacturer.
