Standard keyed door knobs: Cylinder locks, Dead bolts, Keyed entry
- Standard keyed door knobs: the lock is in the center of the door knob, typical for a home’s exterior doors and in various commercial settings.
- Cylinder locks: Ideal for large buildings that need to change the locks frequently; the cylinder gets replaced rather than the entire door knob.
- Dead bolts: A separate lock installed above the door knob.

It’s good to take measurements even if you are fairly certain you have standard size door knobs. In some cases, the new lock may not work or the door knob might not even fit into the opening. Measure the door knob opening and the distance from the edge of the door to the center of the opening, then look for new door knobs that fit into the right measurement or range.
