A sliding glass door that will not lock is a security concern and a daily frustration. Sliding door locks use a hook or latch inside the handle set that catches a keeper on the frame. When the latch breaks, the handle loosens, or the door sits at the wrong height, that hook no longer engages properly.
Our sliding door lock repair service identifies whether the lock itself has failed or whether the door's alignment is keeping it from catching. We then repair, adjust, or replace the latch, keeper, and handle set as needed so the door closes and locks the way it should.
Common symptoms
- The latch does not catch when the door is closed
- You have to lift or push the door for the lock to engage
- The handle is loose, cracked, or wobbles
- The locking lever moves but nothing locks
- A key cylinder is stiff or no longer turns
- Missing or damaged keeper on the frame
Our repair process
- 1
Test the lock
We check the latch, keeper, and handle with the door in its normal closed position.
- 2
Check alignment
Roller height and panel position are reviewed, since a dropped panel is a common reason locks miss.
- 3
Repair or replace
Broken latches, handles, or keepers are repaired or replaced with compatible hardware.
- 4
Align the keeper
The keeper and latch are lined up for a positive catch.
- 5
Confirm operation
We lock and unlock repeatedly to confirm consistent engagement.
Benefits
- Restores reliable locking
- Firm, comfortable handles
- Adds the option of auxiliary locks if you want extra security
- Prevents forcing the door, which can damage the frame
When replacement may be appropriate
If the panel's latch pocket is cracked or the frame has warped so the keeper cannot be set properly, a larger repair may be required. We'll explain the options clearly.
Frequently asked questions
Why won't my sliding door lock anymore?
Common causes are a broken latch, a loose or missing keeper, or a door panel that has dropped so the latch no longer lines up with the keeper.
Can you replace just the handle?
Often yes, as long as compatible hardware is available for the door. Handle sets vary in hole spacing and latch style, so we match them to the door.
Can you add a keyed lock to a sliding door?
Many sliding doors can accept keyed handle sets or auxiliary locks. We can review what fits your door.
Is a sliding door lock repair a quick job?
It depends on whether parts are on hand and whether alignment work is also needed. We'll give you a clear expectation once we know the cause.
Should I add a security bar?
A bar or auxiliary lock can be a useful addition, but it works best alongside a properly functioning primary latch.
