Mortise Lock Repair & Replacement
Older homes in Broadmoor, CA carry a lot of character — original hardwood doors, period-correct hardware, and in many cases, full-size mortise lock mechanisms that have been quietly doing their job for fifty years or more. A mortise lock is fundamentally different from the cylindrical deadbolts most people are used to: instead of a simple hole bored through the door, a deep rectangular pocket is chiseled into the door edge to house a self-contained lock case that integrates the latch, deadbolt, and sometimes the strike all in one unit. When that case wears out, seizes, or fails entirely, the repair process demands precision — and an understanding of hardware that not every technician carries.

Frequently asked questions
What is a mortise lock and how is it different from a standard deadbolt?
A mortise lock is a self-contained locking mechanism that sits inside a deep rectangular pocket — the mortise — cut into the edge of the door. Unlike a standard cylindrical deadbolt, which requires only a round bored hole and mounts on the face of the door, a mortise lock integrates multiple functions (latch, deadbolt, cylinder, and cam mechanism) into a single case. This makes it more robust and historically was the default in quality residential and commercial construction. Many homes in Broadmoor still have original mortise hardware on their entry and interior doors.
Can a mortise lock be repaired rather than fully replaced?
Yes, in many cases. The most common repairable failures include worn cam followers, broken or fatigued deadbolt springs, a seized or damaged mortise lock cylinder, and a stripped hub. If the case body itself is intact, our technicians can open the case, replace the failed component, and reassemble without disturbing the door frame at all. Full case replacement becomes necessary when the body is cracked, when the internal mechanism is so worn that piecemeal repair would only delay the next failure, or when the original case format is discontinued and replacement parts are no longer available.
How much does mortise lock repair or replacement cost?
We do not quote prices in advance over the phone because the final figure depends on several real variables: the specific lock type and brand (a Baldwin mortise lock or Corbin Russwin case may require proprietary parts), whether the job is a cylinder swap, an internal rebuild, or a full case replacement, the time of day you call, and the travel distance to your location. What we commit to is confirming an exact price with you before any work begins — no work starts until you have approved the quote.
Do you work on electric mortise locks and smart mortise locks?
Yes. Electric mortise lock installations are increasingly common in multi-family rentals and small commercial properties throughout the Daly City and Broadmoor area, and our technicians handle both the mechanical installation and the basic low-voltage wiring connections those locks require. For smart mortise lock retrofits — where a property owner wants keypad or app-based access while keeping the existing door and trim — we can assess whether the current mortise pocket dimensions are compatible with available smart lock formats and carry out the installation and programming.
What should I do if I am locked out and have a mortise lock on my door?
First, check for a spare key with a trusted neighbor or family member, or check whether another entry point to the property is accessible. Do not attempt to force or bypass the lock yourself — older mortise cases and the door stiles around them can be damaged permanently, and the repair cost rises significantly. Call our 24/7 emergency locksmith line at (650) 977-2027. Before we begin any work, we will ask you to confirm ownership or authorized occupancy of the property — this is standard practice and protects everyone. Our goal is always to restore your access with no damage to the door or frame wherever that is mechanically possible.
Can you re-key a mortise lock cylinder to match my other house keys?
Yes. Mortise lock cylinders are removable — the cylinder is extracted from the case using a setscrew or cam release, re-pinned to the new key cut, and reinstalled. If your existing cylinder is in good shape and the key profile is a common format, re-keying is typically the most direct solution. If the cylinder is worn, corroded, or uses a discontinued profile, we can replace the mortise lock cylinder with a compatible modern unit pinned to your key of choice. We can also extend this to a master key system if you manage multiple units or doors on the same property.
