A remote keyless system is a system designed to remotely permit or deny access to premises or automobiles. There are several RKE systems on the market, including but not limited to KeeLoq by Microchip, HITAG by Philips, and AVR411 by Atmel.
In the case of automobiles an RKS performs the functions of a standard car key without physical contact; power door locks can be locked or unlocked from several feet away or even from inside a building. (In this regard, the term "keyless" is a misnomer since the fob acts as an electronic key. Locking it in the car is just as much of a problem as doing the same with a mechanical key.)
A remote keyless system can include both a remote keyless entry system (RKE) and a remote keyless ignition system (RKI).
Remote keyless systems first began appearing as an option on several American Motors vehicles in 1983, including the Renault Alliance. The feature gained its first widespread availability on General Motors' W-platform vehicles (the Buick Regal, Oldsmobile Cutlass Supreme and Pontiac Grand Prix) in 1989.
