Locks do not usually fail all at once. They degrade. The key starts sticking slightly.
The deadbolt stops throwing smoothly. The latch gets rougher to turn. Coastal homeowners on Hutchinson Island see this faster than inland homes because salt air accelerates the wear.
Most homeowners wait until the lock actually fails completely before calling. By then the cylinder is usually beyond simple cleaning and needs rebuild or replacement. Catching a sticky lock early is much cheaper - a proper service call is $85 to $125.
A full replacement after seizure is $250 to $425.
Treasure Coast Locksmith repairs residential locks across every city in the tri-county area. We rebuild pin tumbler cylinders, replace broken latches, fix bent deadbolt throws, and restore corroded coastal hardware. Mobile service, usually same-day.
What proper lock repair includes
- Disassembly and inspection - we pull the lock apart, not just spray lubricant in the keyway.
- Pin tumbler replacement - worn pins swapped with factory OEM parts.
- Latch and bolt restoration - bent deadbolt throws straightened, weak springs replaced.
- Strike plate alignment - misaligned strikes are a common silent failure cause.
- Coastal lubrication - pin tumbler-safe dry lubricant, never WD-40.
- Full operation test - key, thumb-turn, door swing all verified before leaving.
- Same-day service - most repairs finish in 30 to 60 minutes onsite.
- Rebuild vs replace guidance - honest recommendation based on cost and remaining life.
Why Treasure Coast locks fail
Every lock failure has a specific cause.
Identifying it is half the job.
Common lock failure modes we fix
- Key sticks and catches during the final turn on a Tradition home. Pin tumbler wear - rebuild with fresh pins in 20 minutes.
- Deadbolt will not extend fully on a Fort Pierce home with a swollen wood jamb. Strike plate realignment and latch adjustment.
- Vero Beach oceanfront home with a deadbolt cylinder that has seized solid from salt corrosion. Soak, clean, rebuild with PVD hardware if needed.
- Front door handle set wobbles loose on a Jensen Beach home. Tighten mounting bolts and replace worn internal spring cassette.
- Kwikset SmartKey stopped responding on a Stuart home after a key mis-insertion. Reset or replace the SmartKey cam assembly.
- Back door lock is wet from lanai spray and now turns rough. Disassemble, dry, lubricate, reassemble, add weather seal.
- Garage side entry deadbolt is binding because the house has shifted on the slab. Plane the door, realign strike, test.
- Sliding patio door lock will not engage the keeper. Replace the keeper, shim if needed, verify door alignment on the track.
Rebuild vs replace - when each makes sense
Lock repair decisions come down to cost arithmetic. A full rebuild of a standard Schlage or Kwikset cylinder runs $85 to $145 including parts and labor. A complete replacement of the same cylinder with new hardware runs $125 to $225.
For a cylinder that has another 5-10 years of life in it, rebuild is cheaper. For a cylinder that is near end-of-life, replacement is a better investment.
How do you tell? Three indicators. First, age - most residential cylinders are designed for 10 to 20 years of normal use.
Second, finish condition - if the external finish is already pitting or corroding, the internal parts usually are too. Third, mechanism wear - if the pin tumblers are visibly rounded or the key is worn, the whole cylinder is tired and a rebuild is a temporary fix.
Our standard practice is to assess every lock before we start the repair. If it is salvageable we rebuild. If it is not, we recommend replacement and show you why.
We never push a replacement unnecessarily, because a satisfied customer who got a $95 rebuild comes back to us a year later for a $425 full-house rekey. That math favors honesty.
Coastal locks are a special case. Within three blocks of the beach, standard zinc-alloy locks corrode from the inside out within 12 to 24 months. A rebuild on a corroded coastal lock is usually a waste of money because the next corrosion cycle will start within weeks.
For coastal homes we always recommend PVD-coated or solid-brass replacement, which costs more up-front but lasts 5 to 10 years in salt exposure.
How a lock repair call works
Phone call and description
Call (772) 758-1322 and describe the symptoms - sticky, seized, rough, loose. We quote a range on the phone.
Onsite assessment
Technician inspects the lock, verifies whether rebuild or replace is the better call, and confirms the quote.
Disassembly and repair
Lock pulled, cleaned, pins and springs replaced as needed, reassembled and lubricated with pin-safe lube.
Test and handoff
Full operation test with key and thumb-turn. Workmanship warranty written on the invoice.
Lock maintenance tips for Treasure Coast homes
- Never use WD-40 or oil-based lubricant in a pin tumbler lock. It gums up the pins over time. Use graphite or dry silicone.
- On coastal homes, lubricate cylinders every 6 months. Inland homes can go 12-18 months between lubrication.
- A key that starts to stick is a warning - rebuild at $95 is cheaper than replacement at $275 after seizure.
- Door swelling and settling can make locks feel stuck even when the cylinder is fine. Check strike alignment first.
- Replace your exterior locks every 8-12 years on the coast, 15-20 years inland. Factory mechanical life is real.
- Keep brass and PVD-coated hardware clean with just water. Never use acid cleaners that can pit the finish.

Lock repair FAQs
The questions Treasure Coast homeowners ask when their locks start acting up.
How much does lock repair cost?
A standard residential lock rebuild runs $85 to $145 including parts and labor. Cylinder replacement runs $125 to $225. Full handle set rebuilds with spring cassette replacement run $165 to $285.
Price is confirmed on the phone before dispatch and again onsite before the repair starts.
Can you fix a sticky deadbolt that's hard to turn?
Yes. Sticky deadbolts are usually caused by worn pin tumblers, dried-out lubricant, or misaligned strike plates. We disassemble the cylinder, clean and re-pin, lubricate with pin-safe lube, and realign the strike if needed.
Most sticky deadbolts are back to factory operation in 30 minutes.
My key broke off in the lock. Can you extract it?
Yes. Broken key extraction is a standard service. We use specialty extractor tools to pull the blade out without damaging the cylinder.
Most extractions take 5 to 15 minutes. If the cylinder was damaged during the break, we can rekey or replace at the same visit.
Can you repair a Schlage or Kwikset lock or do I need to replace it?
Most Schlage and Kwikset locks are repairable if they are under 10-15 years old and the outside finish is still intact. We check the cylinder, pins, springs, and cam for wear, and rebuild with factory OEM parts. If the lock is too worn to rebuild reliably, we recommend replacement.
What if my lock is seized and won't turn at all?
Seized locks are usually caused by corrosion, debris, or bent internal parts. We first attempt to free the mechanism non-destructively with penetrating lube and gentle manipulation. If that fails, we drill a controlled path through the cylinder (not the door) and replace with a new cylinder rekeyed to your existing key.
Why does my beach house lock corrode so fast?
Salt air accelerates corrosion on standard zinc-alloy and chrome-plated locks. ASTM B117 salt spray testing shows most residential locks failing within 400 to 600 hours of exposure, which on the Treasure Coast oceanfront is 12 to 24 months of real time. PVD-coated or solid-brass hardware extends this to 5 to 10 years.
Can you fix a loose door knob or handle set?
Yes. Loose knobs and handle sets are usually caused by bolts backing out, worn internal springs, or damaged rose plates. We tighten or replace the mounting bolts, replace the spring cassette if needed, and verify operation.
Most knob tightening jobs take 15 to 20 minutes onsite.
Do you repair sliding patio door locks?
Yes. Sliding patio door lock repair is a specialty. Common failures are broken lock hooks, damaged keepers, misaligned strikes, and worn tracks.
We repair or replace the lock hardware and adjust the door alignment on the track if needed. Most sliding door repairs take 45 to 75 minutes.
What if the strike plate is the problem, not the lock?
Strike plate problems cause about 30% of the 'broken lock' calls we get. Doors swell from humidity, houses settle on the slab, and strike plates slip out of alignment. We realign the strike, add shims if needed, or reinstall with 3-inch screws into the framing stud.
This is usually a 20-minute fix.
Can you fix a bent deadbolt?
Sometimes. Minor bending from a pry attempt or a forced key can be straightened. Severe bending usually requires cylinder replacement.
We assess onsite and give you the honest recommendation. Straightening is about $85. Replacement runs $125 to $225 depending on grade.
How long do residential locks last?
A Grade 1 deadbolt with proper lubrication and no coastal exposure should last 20 to 30 years. Grade 2 runs 15 to 20 years. Grade 3 big-box locks run 5 to 10 years.
Coastal exposure cuts these numbers roughly in half. Smart locks have a mechanical life similar to Grade 2, plus electronic components that age separately.
Do you repair smart lock mechanical parts?
Yes. The mechanical side of smart locks (cylinder, bolt, strike) wears the same as standard deadbolts. We repair or replace the mechanical parts the same way.
Electronic repairs are brand-dependent - we handle Schlage and Yale electronics but Kwikset Halo and August typically go back to the manufacturer for electronic repair.
