How Does a Mortise Lock Cylinder Work?

Mortise lock cylinders work by using a series of pins that are pushed up and down by the key. The pins are set to specific heights, and when the key is inserted into the cylinder, it pushes the pins up to their correct height, which allows the lock to turn and the door to be unlocked. When the key is removed, the pins fall back down into the cylinder, and the lock is engaged again.
