Keyed hardware is used on doors that can be locked from the outside with a key. These doors can be locked from both inside and out, but the outside is physically with a key. Security door knobs like an Schlage door knob are used on exterior doors, sheds and gates.
An Schlage door knob is a good choice for keyed door knobs. Schlage is known for their security door knobs and locks.
