Using a Key Programmer
Modern key fobs go beyond simply keys; they can communicate with a vehicle to start it, open the rear hatch, and much more. To accomplish this, they have to be programmed together.

The device essentially reprograms the digital signature of the chip inside the key to match that of the vehicle, and allows it to start.
Certain vehicles come with electronic immobilizers that protect against theft by stopping the engine from starting if it is not equipped with the correct key or fob. The system checks to determine if the key or fob is digitally signed. The system will turn off in the event that it doesn't. This type of system is efficient in reducing theft of automobiles, and has been made compulsory for many models of car by the manufacturer.
