Mortise lock replacement.
A patio door that will not lock is a room out of inventory and a liability on the property. We replace the lock body inside the stile, set the keeper, and correct the alignment so the hook grabs every time.
Clear quotes
Lock replacement is quoted per door.
Commercial work is priced per property rather than at the residential flat rate. We walk the doors with you or your maintenance lead, count the units, and send a written scope with per-door pricing before anything is scheduled. Multi-door and multi-building work is quoted as one package so you have a single number to take to ownership.

What we handle
Security issues we resolve.
- Latch spins freely and never engages the keeper
- Door has to be lifted or shoved before it will lock
- Keyed exterior locks that no longer turn
- Units taken out of service because the slider will not secure
- Five different lock types across one building
- Residents or guests reporting doors that feel unsecured
Securing units, and keeping them that way.
The mortise lock is buried inside the door stile where nobody sees it until it fails. When the internal mechanism gives out the handle keeps turning but the hook never extends, and the door is effectively unlocked while looking perfectly normal.
We replace the lock body and set the keeper in the frame, then check the panel alignment. That last part matters: a door sagging on worn rollers drops the hook below the strike, and a brand-new lock in a misaligned door still will not secure.
Across a property we try to standardize. Where door systems allow it, fitting the same lock and keeper everywhere means your team stocks one spare part instead of hunting a match every time a unit calls in.
How this service works
Clear steps from first call to finished door.
Step 01
Identify the units
We log which doors will not secure and prioritize them ahead of the rest of the scope.
Step 02
Survey and specify
Each door's lock body and keeper are identified so hardware can be standardized where possible.
Step 03
Replace and align
The lock body is replaced, the keeper is set, and panel alignment is corrected so the hook engages.
Step 04
Test and hand back
Every door is locked and unlocked with your maintenance lead before the unit returns to service.
