Keying a lock, this 1-1/8" mortise cylinder is the replaceable keyed core for a mortise lock -- turning the key operates the lock, and a worn, lost-key, or rekeyed core can be swapped out without replacing the whole lock. It threads into a mortise lock body in the door edge, turns the latch or bolt through the cam, and comes with its own unique key, so each lock opens separately. Matching the cylinder length to the lock and the door thickness is what lets the key turn freely and the cam engage. It is a replacement and rekeying cylinder for mortise locks.
