Lock Repair
Sticky, loose, or damaged lock? We diagnose and repair residential locks before they become a real problem.
About this service

Ignoring them often leads to a lockout or a security gap at the worst possible time. We diagnose what is causing the issue, repair it on the spot if possible, and tell you honestly when replacement makes more sense than repair.

Common Causes of Lock Repair
A key that's getting harder to turn
Worn or dirty internal pins gradually increase resistance until the key barely turns, often right before it breaks off.
A deadbolt that won't extend fully
Misaligned strike plates or worn bolt mechanisms can prevent the bolt from throwing all the way, leaving the door only partially secured.
A door that has settled or shifted
Homes shift over seasons, and a door that used to latch smoothly can bind against the frame, straining the lock mechanism.
Loose lock hardware
Screws that back out over time from repeated door slamming can make the whole assembly wobble and stick.
Corrosion or debris inside the mechanism
Dust, humidity, and lack of lubrication cause internal components to gum up, especially on exterior doors.
Prior break-in attempt
A lock that was picked, pried, or hit can have bent internal parts that only become obvious the next time it's used.
A recently installed lock that was never adjusted correctly
A lock installed slightly off from day one can develop worsening symptoms over time as the door settles further.
Humidity swings common to Upstate SC summers
Seasonal humidity changes cause wood doors to swell and shrink, which can throw off a lock's alignment even without any hardware defect.
A latch that doesn't retract fully when the handle is turned
Worn internal springs or a bent latch bolt can prevent the mechanism from retracting all the way, making the door feel stuck even when unlocked.
The Risks of DIY Lock Repair
Lubricating with the wrong product
Household oils like WD-40 attract dust and grime over time, making a sticky lock worse instead of better.
Adjusting the strike plate without checking door alignment first
Moving the strike plate to compensate for a misaligned door can mask the real problem and cause the deadbolt to bind again later.
Forcing a stuck lock
Applying extra force to a sticking key or bolt is a common way keys snap off inside the cylinder.
Missing a worn part that will fail again soon
A quick fix without diagnosing the root cause often means the same problem returns within weeks.
Not knowing when repair isn't worth it
Some locks are cheaper to replace than repair, and without comparing both options you can end up overpaying to fix an outdated lock.
Reassembling internal components incorrectly
Taking a lock apart to diagnose an issue without the right reference can result in it going back together worse than before.
Over-tightening mounting screws to stop a wobble
Cranking down on loose screws without addressing the underlying wood damage can strip the hole further, leaving nothing for the screw to grip.
Spraying lubricant into a lock that needs cleaning, not oil
Adding lubricant on top of existing grime can gum up the pin stack rather than fixing the actual friction point.
Ignoring early symptoms until the key snaps
A lock that's getting progressively harder to turn is a warning sign, and delaying repair increases the odds of a broken key and a full lockout.
What Affects the Cost
