Can I fit an antique door lock today?

Many period locks remain in working order and can be fitted to suitably thick internal doors by a knowledgeable carpenter. Adjustments to the keep or internal springs may be necessary for daily operation. Buyers should check the dimensions and hand of the lock to ensure it matches the swing and thickness of the target door before attempting installation.

How do I date an old door lock?

Dating relies on the materials, fastening methods, and overall architectural style of the casing and brasswork. Hand-forged wrought iron and heavy oak cases generally indicate earlier seventeenth or eighteenth-century origins. Later Victorian and Edwardian examples often feature machine-stamped brass plates, polished steel components, and standardised keyways that reflect industrial manufacturing shifts.

Do these old locks still include working keys?

Some pieces retain their original hand-cut iron or brass keys that operate the internal levers smoothly. Other examples are sold without keys or require specialist attention to function. Listings specify whether a key or matching keep accompanies the lock, which affects both decorative display and practical use.
