Automotive - Remote Keyless Entry

Remote Keyless System (RKS)

Widely used in automobiles, an Remote Keyless System (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 a remote keyless entry system (RKE), which unlocks the doors, and a remote keyless ignition system (RKI), which starts the engine.
