A cylindrical lock is designed to be installed through the door with a knob or lever on either side that retract the latch when turned or depressed. The main advantage of a cylindrical lock is its relatively quick installation.

A mortise lock is a lock that requires a pocket—the mortise—to be cut into the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States.

A dead bolt, deadbolt or dead lock is a locking mechanism distinct from a spring bolt lock because a deadbolt cannot be moved to the open position except by rotating the lock cylinder with the key. The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key.A deadbolt is often used to complement a spring-bolt lock on an entry door to a building.

An interconnected lock is a knob or lever handle and a deadbolt linked together for simultaneous action. There are two types of interconnected lock mechanisms - standard tubular locks with interconnect, and mortise locks.
