If the system is able to recognize the signal, it will trigger to unlock the car doors and activate the computer onboard. Certain systems have another transmitter located in the trunk of the car which opens it when you waggle one foot underneath it.

A unique process of technology known as "programming" is used to set the fob up to work with the specific car's system. This typically involves turning the ignition of the car several times in a certain sequence. It could also require pulling or pushing various levers and buttons or removing fuse.
Once a key fob is programmed to your specific car's keyless entry system, it transmits its digital identity code along with a function code that tells the car what to do (lock, unlock, or open the trunk). The receiver in the car verifies that the transmitter is the person it claims to be by using an authentication and encryption process. If it is authorized, the onboard computer unlocks the vehicle and starts the engine.

This would require a specific device to record the transmission then retransmit it later in the event that the system doesn't anticipate it.
