What goes wrong
Sliding door latches and mortise locks wear out, misalign as the door settles, or seize from corrosion. Suddenly the door won't lock, the key spins, or you have to slam and lift to get the latch to catch.
How we fix it
We replace the mortise lock or latch with a hardened unit, re-align the keeper, and adjust the door so it locks smoothly every time. We can add a secondary foot-bolt or auxiliary lock for extra security.
Signs you need lock repair
- Latch won't catch or engage
- Lock is stiff, loose, or spins
- You have to lift or slam the door to lock it
- Key turns but nothing happens
What We Inspect
- Whether the latch is misaligned with the strike plate
- Internal lock mechanism for worn or broken components
- Key cylinder condition if the door has a keyed lock
- Panel alignment, since a settled door often looks like a lock problem
Repair vs. Replacement
If the mechanism itself is intact but misaligned, a keeper adjustment or panel realignment solves it without new hardware. If the latch or mortise lock body is worn, cracked, or the key cylinder is failing, we replace the lock hardware outright rather than patching a failing mechanism.
Our Process
- 1. Test the lock and latch to isolate mechanical failure from misalignment
- 2. Remove the existing lock or mortise unit
- 3. Install a hardened replacement latch or lock body matched to your door
- 4. Adjust the strike plate and keeper for a clean catch
- 5. Test the lock through several full cycles before we leave

Common Questions
How much does sliding door lock repair cost?
Lock repairs generally run $180–$280 including hardware.
Can you do sliding door lock repair the same day?
In most cases, yes. We carry common parts on the truck and complete the majority of lock repair jobs across South Florida in a single visit.
Do you guarantee the work?
Yes, every repair is backed by a 12-month parts-and-labor warranty in writing, and we're fully licensed and insured.
Can you rekey a sliding door lock instead of replacing it?
If the lock body is in good condition, yes, we can rekey it. Most sliding door lock failures we see are mechanical wear, though, not just a key issue.
Is a sliding door with a broken lock a security risk?
Yes, treat it as a priority. We offer emergency same-day lock repair specifically because an unsecured sliding door is a real vulnerability.
Can you add extra security beyond the standard lock?
Yes, we regularly add foot bolts, auxiliary track locks, or keyed pin locks alongside a lock repair for extra peace of mind.
