What is the difference between those functions?

Dummy door knobs are one-sided “fake knobs.”

They’re usually installed on the surface of a door or behind it.

Some come in pairs so you can use them on double doors.

These types of door knobs don’t have any working parts.

They’re good for a shallow closet or small pantry and the interior of French doors.

Passage door knobs are similar to dummy door knobs.

They don’t lock but are used to open doors and go between rooms.

Passage door knobs are ideal for interior hallways, closets and other rooms that don’t need privacy locks.

They’re also called unkeyed knobs.



Keyed entry door knobs have a lock and key mechanism on both sides for safety and security.

They’re used on front doors, patio doors, garage doors that go into your home or other exterior doors.

Some have a button on the inside that you press to lock the door.

The button unlocks when you turn the interior knob.

Other keyed entry door knobs have a twist mechanism on one side that you turn to lock or unlock the door.



Privacy door knobs have a twist or button lock that works from only one side.

Some privacy door knobs with button locks have a pin hole on the outside knob and a generic key that opens the lock.

These types of door knobs are typically used in bathrooms, bedrooms and other rooms that call for privacy but don’t need keyed locks.
