Quick Answer

Here is the simplest way to choose the correct door hardware function.

Keyed Entry

Locks with a key. Best for exterior doors and controlled-access rooms.

Privacy

Locks from the inside without a key. Best for bathrooms and bedrooms.

Passage

No lock. Best for closets, hallways, and rooms that do not need privacy.

When You Need a Pull but No Latch

If you have a door that does not need to latch, such as a double door where one side is fixed or a closet with roller catches, you may need a dummy knob or lever.
