Some systems have an additional transmitter in the trunk of the car which can be opened when you put a foot under it.
Each key fob is assigned a unique digital identification code by the manufacturer. A proprietary technical process called "programming" is used to set the fob up to work with the specific car's system. This usually involves turning the car's ignition repeatedly in a specific sequence, and could include pulling or pushing various levers and buttons or removing fuse.
Once the key fob is programmed into your car's keyless system it transmits a digital identity code as well as a function-code to tell the car what to (lock or unlock the trunk). The receiver on the car verifies the transmitter's identity through an authentication and encryption process. If it is authorized, the computer on board unlocks the vehicle and starts the engine.

This requires an instrument that records the transmission, and then retransmits it later when the system doesn't expect it to.
