Why a door lock starts fighting you.
Most locks we are called to repair are not broken inside. The lock is fighting the door, dirt in the cylinder, or a part that has worked loose.
That matters for door lock repair in Dallas, because a lot of the trouble starts below the floor. Much of North Texas sits on expansive clay that swells when it is wet and shrinks in long dry spells. As the soil moves, a slab can shift slightly, and door frames go a little out of square with it. A small shift is enough to put a deadbolt off its strike hole. It is one reason a lock can work fine in spring and start fighting you in August.
Not every sticking lock is a foundation story. Loose hinge screws let a heavy door sag. Pins and keys wear down over years of use. A cylinder that has gone dry, or been sprayed with oil that collected dust, makes the key drag. Inside a knob or lever, set screws back out and latch springs break.
Fix the door first, then the lock. A new lock on a door that still sags will bind the same way.

What you notice at the door, what usually causes it, and what the fix looks like.
Key turns hard
Usual cause and fix
- A dry or dirty cylinder, or worn pins and a key that is a copy of a copy.
- Clean the cylinder, dry lube it, and replace worn pins. A fresh key cut to the lock beats a worn copy.
Deadbolt won't throw
Usual cause and fix
- The bolt hits the strike edge, or bottoms out in a pocket that is too shallow.
- Tighten the hinges, reset the strike, and clear the pocket so the bolt reaches its full throw, about an inch on most home deadbolts.
Latch won't catch
Usual cause and fix
- The latch rides past an off-line strike, or the latch spring has broken and the latch no longer springs out.
- Adjust the strike, or replace the latch with one that matches the lockset and the door's backset.
Loose knob or lever
Usual cause and fix
- Mounting screws backed out from daily use, a loose set screw, or a worn spindle.
- Tighten or replace the screws and the spindle. A cracked chassis means replacing the lockset.
Only sticks in summer
Usual cause and fix
- Seasonal clay-soil movement shifts the frame, so the bolt and strike drift out of line.
- Reset the strike for today's position. If several doors stick at once, have the foundation looked at too.
Lever droops
Usual cause and fix
- A weak or broken return spring inside the lever, common on lighter residential levers.
- Replace the spring where the maker sells one. Where it does not, a new lever set costs less in labor.
If the lock body is cracked, the parts are no longer made, or the old keys are a worry too, repair stops being the best value.
Rekey vs replace: the full comparisonRepair or replace: where we draw the line.
We price the repair and the replacement on the same call, so you can choose.
Cylinder service
When the lock body is sound, a worn cylinder is taken apart, cleaned and repinned instead of replaced.
Repair makes sense when the lock body is sound and the problem is alignment, dirt or one worn part.
Strike adjustments, cylinder service and latch replacements are small jobs. They keep hardware you already have keys for, and on a good deadbolt or a quality lever set, that is usually the better value.
Replacement makes more sense when the housing is cracked, the lock was damaged in a break-in, the maker no longer sells the part, or a worn builder grade lock would cost nearly as much to repair as a new one. If what bothers you is who still has a key, a rekey changes the pins without new hardware.
We tell you which one your door needs. You make the call.
For reference, our Dallas locksmith cost guide puts residential lock replacement at $75 to $200 per lock and up, depending on hardware grade, and a residential rekey at $20 to $45 per lock plus the service call. See the rekey vs replace comparison for how to choose.

Open- Step 1
Find the cause with the door shut
We work the lock with the door open, then closed. If the key turns freely open but binds closed, the problem is alignment, not the lock. Marking the bolt and closing it against the strike shows exactly where it hits.
- Step 2
Strike adjustment
Hinge screws come first. Then the strike plate is moved or its opening is filed so the bolt and latch enter without dragging, and the pocket behind it is cleared so the deadbolt throws all the way. Strike screws long enough to bite into the framing hold the adjustment better than short trim screws.
- Step 3
Cylinder service or latch replacement
A cylinder that drags is taken out, cleaned and dry lubed, and worn pins are replaced. A latch with a broken spring is swapped for one that fits the lockset and backset. Loose knobs and levers get their screws, set screw or spindle put right.
If the lock itself is past saving, we stop and price the replacement before going further.
- Step 4
Tested before we leave
Every repaired lock is worked several times with the door closed, with each key you use, from both sides. You try it yourself before we pack up.

Door lock repair questions.
How much does door lock repair cost in Dallas?
It depends on the cause. A strike adjustment or cylinder service is mostly labor, while a new latch, spring or cylinder adds the part. The price is the service call plus the repair, and evening or weekend calls add an after hours rate of $25 to $75. For comparison, our cost guide puts a full residential lock replacement at $75 to $200 per lock and up. We give you the number on the phone before anyone is sent.
Should I spray WD-40 or oil into a sticking lock?
No. Oil frees the lock for a short time, then holds dust and grit that gum up the pins, and the lock ends up worse. Use a dry lube made for locks, such as a PTFE dry lube or a small puff of graphite. Do not mix graphite and oil in the same lock, because together they form a paste.
Why does my deadbolt lock with the door open but not when it is closed?
Because the lock is fine and the door is out of line. When the door sags or the frame shifts, the bolt meets the edge of the strike plate instead of the hole. Forcing the key can bend the key or damage the cam. The fix is to tighten the hinges and reset the strike so the bolt throws all the way.
Can foundation movement in North Texas affect my door locks?
Yes. Much of DFW sits on expansive clay that swells when wet and shrinks when dry, and that movement can shift door frames enough to throw a deadbolt or latch off its strike. We can realign the strike, but if several doors start sticking together, or you see new cracks, it is worth having the foundation checked as well, because the doors may move again.
Is it better to repair or replace a door lock?
Repair when the lock body is sound and the problem is alignment, a dry cylinder or one worn part. Replace when the housing is cracked, the lock was damaged in a break-in, parts are no longer made, or a worn builder grade lock would cost nearly as much to fix. If your concern is who has a key, rekeying is the cheaper fix.
Do you repair locks on business doors too?
Yes. We work on commercial doors across DFW as well as homes. Heavy, high traffic doors wear latches and levers faster and can sag on their hinges, and the same alignment and parts checks apply. If the real problem is the door or frame rather than the lock, we tell you.
