Mortise Lock Replacement & Conversion in Sacramento

Keep your door. Update the hardware.

An old or discontinued mortise lock does not always mean you need a replacement door. Able Smart Key & Lock offers mortise lock replacement and custom conversion services for suitable existing doors. Our custom conversion process allows selected doors to accept compatible modern replacement hardware.

What is left when an old mortise lock is removed?

A mortise lock body sits inside a pocket cut into the edge of the door. Removing the old lock and trim can expose that pocket along with existing knob, key or cylinder openings on the door faces. Our photographs illustrate examples of these existing openings.

A solution tailored to your door

Each installation is tailored to the door's condition, existing openings, replacement hardware and the appearance you want to achieve. Existing holes can be concealed with suitable cover plates or filled with appropriate wood filler, depending on the opening and the agreed scope of work. We may use metal cover plates or paintable ASA plates where suitable.

For painted doors, appropriate wood filler can be used to restore suitable areas before sanding and painting. Limited filling work may be available by separate agreement and quote. Filling is not automatically included in every conversion.

Stained wood doors need additional consideration because visible repairs must blend with the existing wood and finish. We discuss practical options and the expected appearance before proceeding.

Sandable, paintable inserts

Our conversion inserts are sandable and paintable. The installed insert face shown in the door-edge example is a raw result before final preparation, sanding and painting for a clean appearance. The replacement latch is not yet fitted in that particular photograph. It illustrates the visible insert face rather than a fully finished installation.

Caulk is not routinely necessary; any additional preparation depends on the condition of the individual door. Painting and refinishing are not automatically included. We agree on the scope of filling and finishing, and who will complete it, before work begins.

Common questions

Can I replace an old mortise lock without replacing the door?

In suitable cases, yes. We evaluate the door and existing hardware before recommending replacement or conversion options.

What happens to the old holes?

Depending on your door and the desired result, existing holes can be covered with suitable plates or filled with appropriate wood filler. Any filling and finishing work is discussed and quoted as part of the agreed scope.

Can any mortise lock be converted?

Yes, provided the door itself is in good enough condition for the conversion. We assess the door and tailor the conversion to its existing openings, the replacement hardware and your desired result.
