Certain systems include an additional transmitter in the trunk of the car that opens when you move your foot beneath it.
Each key fob is given an unique identification code by the manufacturer. A unique process of technology known as "programming" is used to make sure that the fob is set up with the car's specific system. This requires turning the ignition of the vehicle repeatedly in a certain sequence, and may also require pulling levers or buttons or removing the fuse.
Once the key fob is programmed into your car's keyless system, it transmits a digital identification code and a function code to instruct the car on what to do (lock, unlock or open the trunk). The receiver on the car checks the authenticity of the transmitter by an authentication and encryption process. The computer in the car will unlock the vehicle and start the engine if it's authenticated.
