It houses a series of spring-loaded pins that lock the door when there is no key placed into the hole. When a key is placed into the doorknob the uneven edge presses upwards on the pins inside of the cylinder, allowing them to fit into their proper place. When the pins fit into the cylinder, they allow the bolt, also known as the latch, to move forward, and then engage the door's inside.

The screw holes can be machined either through an interchangeable insert 16, or directly into the faceplate body. An intermediate portion of the faceplate is a stepped section that serves as an index mark to identify a specific place on the blank workpiece.

The stepping area has also been designed to resist abrasion to ensure that the fastener doesn't damage the chisel you use to cut it. The body's surface of the faceplate has different characteristics from the surrounding area and machining into this region warns the turner to possible contact with the fastener and gives the turner enough time to react.

Screws used to fix to a faceplate should have a little free play in the screw hole. There should be no space left behind the screw after it is tightened on the block of glue, as this could allow the block to shift during the turning.

In addition to securing the bolt, the strike plate also holds the cylinder in place. There should be three holes along the bolt: one located in the middle connects the facepiece to the cylinder; the other two are to the left and right of the central hole.
