Sliding Door Mortise Lock Repair in Atlanta
A mortise lock is set into the edge of the sliding panel and works with a keeper mounted in the frame. Because it's concealed, a fault can look like a handle problem or a lock that simply "won't turn."
The problem
What we see and how we fix it
Mortise locks reward specialist diagnosis. We check the lock body, the handle drive, the keeper, and — critically — whether the panel still lines up with the keeper at all.
Signs you need this
When to call us
- The handle turns but the latch doesn't throw
- The lock binds or won't retract cleanly
- The keeper and latch no longer meet
- A concealed lock body that feels gritty or stiff
Our process
How the visit goes
Access and inspect the mortise lock body and handle drive
Test engagement between the latch and keeper
Repair or rebuild the mechanism where serviceable
Correct panel and keeper alignment
Confirm smooth throw and secure latching
Repair or replace? A mortise lock that's binding can sometimes be serviced rather than replaced. If the body is worn out, we fit the correct replacement.
Questions
Sliding Door Mortise Lock Repair FAQs
What is a mortise lock on a sliding door?
It's a lock body recessed into the edge of the panel that drives a latch or hook into a keeper in the frame.
Why does the handle turn but nothing locks?
The internal drive or latch may have failed, or the panel has shifted so the latch no longer meets the keeper.
Can a mortise lock be repaired or only replaced?
It depends on the wear. Many can be serviced; a failed body is replaced with the correct mechanism.
