Lockset
A lockset is a term used to describe a lock supplied complete with the lock furniture. The requirements of the door application would determine the type of lock and lock furniture required.

A sashlock is fitted into the leading edge of a door and is operated by using a key. Door handles with a keyhole in the back plate would be fitted to the face of the door and used in conjunction with the sashlock. The lever operates the latch part of the lock and the key operates the deadbolt part of the lock. This lockset would be used on doors that are required to lock with a key.
