A lock is a mechanism that secures goods or limits access to something that need protection. A mechanical lock is attached to a door and consists of two physically independent pieces. The first section is attached to the frame and serves as a solid metal reinforcement for a hole in the door. The other component fits into a rectangular hole in the door known as a mortise and is made comprised of a metal mechanism that slides a heavy bolt into and out of the reinforced hole.

When a key is turned clockwise or counterclockwise, the bolt slides from one side to another. It must be powered by a mechanism that converts rotational motion (the turning key) into reciprocating motion (the sliding bolt), such as a cam or a crank mechanism. A collection of fixed or moving metal pieces known as wards or tumblers fit into slots cut into the key and are an integral part of a lock's mechanism. This means that just one key can turn the cam, slide the bolt, and open the door. This article rates the top featured manufacturers and suppliers of locks on Thomas, as well as the top lock suppliers in the United States that meet diversity requirements.
