Door Lock Repair in Jacksonville, FL

A deadbolt that won't throw, or a door that won't latch

Open the door and work the deadbolt while it hangs free. If the bolt moves easily that way but grinds or stops once the door is closed, the lock itself is healthy and the bolt is missing the opening in the strike plate on the frame.

Schlage names the usual reasons: a house that has settled, hinges that have loosened and let the door sag, and seasonal moisture that warps a door for part of the year. In Jacksonville the season is summer, when a wood door that shut easily in February starts catching on the strike.

The repair happens at the frame. The strike plate gets repositioned or its opening widened, the pocket behind it is cut to the depth Schlage and Kwikset call for, about an inch, and loose hinges are tightened or shimmed so the door hangs true again.

Stiff, gritty or corroded lock cylinders

A key that drags or needs jiggling points to either a worn key or a dirty, dry cylinder. Try a second key: if one turns cleanly and the other fights, a fresh key cut to the lock solves it without touching the hardware.

Along the Beaches, from Atlantic Beach down through Neptune Beach to Jacksonville Beach, salt air and fine sand work into keyways and latches, and the side of the house facing the ocean takes the worst of it. Schlage says it makes no marine-grade finish and recommends particular chrome and matte black finishes for coastal homes.

The technician removes the cylinder, cleans it, replaces worn pins and springs, and lubricates it only with what the lock's maker approves. When corrosion has reached the lock body itself, cleaning will not hold, and replacement goes on the table.

Broken keys, loose handles and older mortise locks

A key that snapped in a front door, padlock or mailbox lock is drawn out with thin extractor tools, and the lock is tested with a good key before the van leaves. If it just happened, our guide to a broken key stuck in a lock covers what is safe to try while you wait.

Knobs and levers that wobble, sag or turn without retracting the latch usually have a loose mounting screw, a slipped set screw or a tired return spring. Each of those is a part, not a new lockset.

Older houses in Riverside, Avondale and Springfield add mortise locks to the list, the boxed lock body housed in a pocket cut into the door's edge. Swapping one for a modern lock means altering an old door, so servicing its springs, latch and cylinder is the sensible first step.

Sliding glass door latches and mailbox locks

A slider locks when its latch hooks a keeper screwed to the frame, and once the two stop lining up, the latch closes on air. The technician resets or replaces the keeper and the latch; if the panel itself has dropped on worn rollers, that is door work rather than lock work, and you are told so.

Mailbox locks follow ownership. The Postal Service handles locks on boxes it maintains, while the owner or manager of the property answers for the rest, so on an apartment or condo cluster box we work with the office's approval, and a locking mailbox you own at the curb is yours to have repaired.

After a break-in: locking again the same day

A kicked-in door usually gives way at the jamb, with the strike torn out of the wood while the deadbolt survives. The technician resets the bolt and latch, fits a reinforced strike with long screws driven into the framing, and works toward a door that locks before the van pulls away.

A cylinder that was pried or drilled, or a bolt that was bent, is replaced rather than repaired. If keys went missing in the break-in, mention it on the call so the other doors can be rekeyed during that visit.

Smart and keypad locks that stopped responding

Fresh batteries come first, since a weak set is the simplest reason for a silent keypad. Newer St. Johns County homes, Nocatee among them, often came with a builder keypad lock already on the front door, and those wear like any other lock.

When batteries do not fix it, Kwikset's troubleshooting points to other causes: a door-handing setup that was skipped, a bolt binding on a misaligned strike, or a hole behind the strike shallower than an inch. A motor can only throw a bolt that slides freely, so the door and strike are aligned first, then the lock is reset and tested with both the code and the key.

If the electronics have failed, our smart lock installation service fits a replacement and sets up your codes.

Business doors: exit devices, closers and storefront locks

Push bars that stick, latches that no longer catch and dogging that has stopped holding are all repairs we handle, whether the device is a Von Duprin, a Detex or another make. Dogging is the hex-key setting Von Duprin provides to lock the push bar down so a busy door swings freely during the day.

LCN describes a door closer as the part that controls the speed and force of a door, with separate main speed and latch speed valves. A door that slams or stops an inch short of latching usually needs those valves set again, and a closer leaking fluid is replaced.

Worn storefront cylinders and aluminum-door locks are repaired or swapped so the shop can lock up the same day. See our commercial locksmith page for rekeys and master keys, and our guide to panic bar repair in Jacksonville for more on exit devices.

Door lock repair, rekey or replace: an honest call

Fix it when the hardware is solid and the fault is one part or one adjustment. If the lock works but you are unsure who holds keys, a lock rekey retires the old keys while the lock itself stays put.

Replacement wins when a builder-grade lock is worn out inside, corrosion has eaten into the body, the part is no longer made, or the repair would cost close to a better lock. The technician says so plainly and prices a lock change instead of patching hardware that will fail again.
