Keyed Entry Door Knobs

Keyed entry door knobs are locking knobsets used on doors that require keyed access. They can be installed on exterior entries as well as interior doors such as offices, utility rooms, storage rooms, and other controlled-access openings. A keyed cylinder provides access from one side, while the opposite side uses an interior operating control depending on the lock design. Keyed entry knobs vary by cylinder and keyway, latch and backset, door thickness compatibility, knob profile, rosette shape, grade, and finish family. Styles include round, egg, tulip, mushroom, square, traditional, transitional, and contemporary knob designs.

Keyed Entry Door Knobs and Locking Knobsets

Keyed entry door knobs combine a turning knob with a keyed locking function. They are used on doors where access from one side is controlled by a key, including front doors, side entries, offices, utility rooms, storage rooms, service doors, and other residential or commercial openings.

Keyed entry is a lock function rather than an exclusively exterior-door category. The keyed vs. privacy vs. passage door hardware guide describes the operating differences between common door lock functions found across knobs and levers.

The keyed side of the knob contains a cylinder and keyway, while the opposite side uses an interior operating control that varies by lock design. The latch engages the door frame during normal operation, while the locking mechanism controls outside access. Backset, latch configuration, door thickness compatibility, cylinder format, keyway, and mounting arrangement vary across different knob families.

On exterior entry doors, keyed knobs are often used with a separate single cylinder deadbolt as part of a coordinated knob-and-deadbolt arrangement. Other installations use the keyed knob as the primary keyed locking function for the opening.

Keyed entry door knob styles include traditional round and ball knobs, egg-shaped profiles, tulip forms, mushroom shapes, square designs, and decorative knobsets. Rosette and trim designs range from simple round plates to square, rectangular, and more decorative profiles.

Individual lock families also vary by cylinder construction, keying system, latch design, security grade, trim dimensions, and interior operating arrangement. Residential entry knobs, utility-focused locks, and heavier-duty configurations can all use the same basic keyed-entry function while differing in construction and intended application.

The collection includes keyed knobsets across traditional, transitional, contemporary, decorative, residential, and utility-oriented designs, with hardware configurations covering a wide range of door preparations and access requirements.
