Keyless Entry System
Instead of having to fiddle around with keys in your purse or pocket Instead of fumbling around with keys in your purse or pocket, you can walk up to your car, press a button on your key fob, and then open the doors and start the engine.

The way a keyless entry system works is by releasing radio signals and then searching for a corresponding response signal from the key fob. If the system recognizes the signal, the car's doors are opened and the onboard computer activated. Some systems have another transmitter located in the trunk of the car that opens it when you waggle one foot underneath it.
Each key fob is equipped with a unique digital identity code that's assigned by the manufacturer. The fob is programmed with an exclusive process known as "programming". This typically involves turning the ignition of the car several times in a certain sequence. It could include pulling or pushing different buttons and levers, or removing fuse.
Once the key fob is programmed into the keyless system of your car, it transmits a digital identity code and a function code to instruct the car on what to do (lock or unlock the trunk). The receiver in the car verifies that the transmitter is who it claims to be by using an authentication and encryption process. If it's authorized, the computer on board unlocks the vehicle and then starts the engine.

This requires a special device that records the transmission, and then retransmits it when the system doesn't expect it to.
