Door Knob, Door Handle & Lock Parts

Shop door knob parts, door handle parts, lock parts, latches, cylinders, trim components, strike plates, screws, springs, tailpieces, replacement hardware, and related service parts for residential and commercial door locks. Use this collection when repairing or maintaining existing knobs, levers, locksets, deadbolts, and keyed hardware rather than replacing the complete lock.

Match replacement parts to the existing lock manufacturer, series, function, door preparation, backset, cylinder or keyway, dimensions, and finish whenever possible. Many lock components are model-specific and are not universal replacements.

Door Knob, Door Handle, and Lock Replacement Parts

Door knob parts and door handle parts can include latches, deadlatches, cylinders, trim pieces, rosettes, screws, springs, tailpieces, strike plates, thick-door kits, privacy turns, mounting hardware, and other service components. These parts are used to repair or maintain existing knobs, levers, locksets, and deadbolts without replacing the complete hardware set.

For common repair categories, browse door latches, strike plates, and door lock cylinders and interchangeable cores. Brand-specific replacement parts are also available for Schlage and Kwikset hardware.

Replacement lock parts are often specific to a manufacturer, lock series, function, backset, door thickness, cylinder or keyway, trim style, and mounting preparation. When replacing an existing component, compare the original part number and dimensions whenever possible. Similar-looking latches, cylinders, faceplates, and trim pieces are not always interchangeable.

If the original part cannot be identified, use the existing lock brand and model information together with measurements of the door preparation and part dimensions. For complete operating hardware rather than repair components, browse door knobs and door levers.
