Remote keyless system

A remote control for a keyless entry system built into an ignition key: pressing a button on the key unlocks the car doors, while another button locks the car and activates its alarm system

A remote keyless system (RKS), also known as remote keyless entry (RKE) or remote central locking, is an electronic lock that controls access to a building or vehicle by using an electronic remote control (activated by a handheld device or automatically by proximity).[1] RKS largely and quickly superseded keyless entry, a budding technology that restrictively bound locking and unlocking functions to vehicle-mounted keypads.

Widely used in automobiles, an RKS performs the functions of a standard car key without physical contact. When within a few yards of the car, pressing a button on the remote can lock or unlock the doors, and may perform other functions.

A remote keyless system can include both remote keyless entry (RKE), which unlocks the doors, and remote keyless ignition (RKI), which starts the engine.
