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]
The centerlock wheel and hub system was first introduced by Rudge-Whitworth in the early 1900s, for use in automobile wire wheels. Initially called "QD" (for "quickly disconnectable") the basic mechanism for "knock-off" style centerlock hubs was patented by 1908. It was quickly adopted by auto manufacturers and racers.
The BCM communicates with other on-board computers via the car's CAN bus system, and its main application is controlling load drivers – actuating relays that in turn perform actions in the vehicle such as locking the doors, flashing the turn signals (in older cars), or dimming the interior lighting.

Electric locks may be connected to an access control system, the advantages of which include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded. Electronic locks can also be remotely monitored and ...

Locking hubs disengage the axle at the wheels, allowing all of the axle to be at rest during normal driving. Nevertheless, a CAD system still makes for much less drag than having the axle completely locked in (which would spin the axles, differential, driveshaft and part of the internals of the transfer case). Like locking hubs, the CAD system ...
