Using a Key Programmer
Modern key fobs aren't just keys; they communicate with a vehicle to start it and open the rear hatch, and so on. To do this, they need to be programmed together.

What is a key-programmer?
A key programmer is a device used to recode a transponder on the fob or key for a car, truck or other vehicle. This is needed when the fob or key must be programmed. This process is often required when a fob or a key is lost or stolen. The device reprograms the chip within the key to match the digital signature of the vehicle which allows it to begin.
Certain vehicles come with electronic immobilizer systems that stop theft by stopping the engine from running without the correct key or fob.

This kind of system is effective in reducing car theft and was made mandatory for a variety of models of cars by the manufacturer.
Most of these anti-theft systems are controlled by a module installed in the vehicle's engine or instrument cluster or ignition lock. In some cases, these modules need special keys that have been designed by experts to function with the anti-theft system. This is typically performed by a dealer or locksmith who uses a computer.
