How door lock repair service can help
A lock can feel broken when the door sags, rubs, or no longer lines up with the frame. The lock, key, hinges, handle, and door should be checked together before parts are replaced.
Tell us what still works, what stopped working, and what you already tried. This helps us understand whether the problem is the key, lock, door, ignition, or remote before the visit.
We confirm that you can approve the work and review the price before service starts. If another repair is optional, it should be explained as a separate choice.

Common situations
Does this match your problem?
Choose the closest example. Small details can change the right service.
Handle or lock is loose
Stop using extra force. Loose mounting can damage the spindle, latch, trim, and door preparation.
Deadbolt misses the strike
Seasonal movement, hinge wear, settling, or a shifted strike can keep the bolt from entering cleanly.
Latch does not spring back
A worn latch, pressure from the strike, debris, or failed internal parts may prevent reliable closing.
Before you call
What to do now
Test open and closed
Note exactly when the key, handle, latch, or bolt begins to bind.
Check door movement
Look for sagging, rubbing, loose hinges, frame cracks, weather changes, and marks around the strike.
Stop adding products
Do not use cooking oil, glue, or random spray. The wrong product can trap dirt or damage parts.
Your options
What can change the right fix
The right choice depends on the key, lock, door, or vehicle and what is happening now.
Which part is failing
The key, lock, latch, bolt, handle, hinges, door, or frame can each cause a similar problem.
Can the lock be repaired
Repair can make sense when the main lock is in good shape. Cracked or badly worn parts may need replacement.
Door material
Wood, metal, fiberglass, aluminum, storm, and historic doors need different adjustment and fastener choices.

Common questions
Door Lock Repair FAQ
Short answers before you call.
Why does my lock work when the door is open?+
The bolt or latch is probably meeting pressure or missing the strike when the door closes. Hinges, frame movement, weather, or strike position can cause it.
Can an old mortise lock be repaired?+
Many can be assessed and some can be repaired, but parts, wear, prior changes, and door condition affect the practical option.
Should I spray lubricant into a stiff lock?+
Do not use household oil or random spray. First identify whether the problem is the keyway, cylinder, latch, alignment, or another part.
