Fast, Reliable Door Lock Repair Across Sunset
Door lock repair in Sunset, FL typically costs $95 to $240 for a standard cylinder repair or rekey, with sliding door lock work running $110 to $280 depending on the hardware. Most of our Commercial Locksmith in Sunset calls are handled same-day, and we carry parts for both the original 1950s and 60s deadbolts and the modern impact-rated multi-point systems that define this part of Miami-Dade. The challenge in Sunset isn’t just a worn kwikset or schlage cylinder. It’s the High-Velocity Hurricane Zone code layer sitting on top of everything, where a single drilled hole can void the windload certification on an impact door.

Why Dunmore Locksmith Is Sunset’s Preferred Door Lock Repair Company
Led by Perry Osgood, our Door Lock Repair team has been part of the Threshold Group family of independent local locksmith shops since 2007. Every technician sent into Sunset is background-checked, identity-verified, and dispatched with a photo ID badge. Before our tech arrives, we send you their name and photo so you know exactly who’s standing on the other side of that door before you turn the handle. If anyone shows up who you weren’t told to expect, that visit is on us.
Our crew serving Sunset carries both legacy residential cylinder tooling and specialized parts for Hoppe and Fuhr multi-point mortise locks used on HVHZ-certified impact doors. That’s the difference between a tech who has to drill a lock to open it and one who can take it apart without breaking the windload seal. Sunset customers regularly mention that dual capability in their feedback to us.
Sliding Door Lock Repair in Sunset
Sliding door lock repair in Sunset usually runs $110 to $280, and the job almost always starts with a misalignment problem. Humidity and salt air from Biscayne Bay work on the aluminum tracks, the rollers sag, and the latch no longer seats cleanly in the strike. On impact-rated sliders, the lock body itself is often a Hoppe mechanism tied to the door’s windload rating, so we never drill it. We remove the handle set, realign the gearbox, and test the locking points before we clear the unit.
Alignment and Strike Work
Sunset’s post-1992 homes frequently have steel-framed impact sliders that shift slightly as the CBS structure settles. When the frame moves even an eighth of an inch, the latch binds. We realign the frame, shim the strike, and restore the throw so the door locks with normal hand pressure.
Mortise and Multi-Point Rebuilds
Older 1960s and 70s Sunset homes often have original aluminum sliders with simple hook latches that have corroded from decades of salt air. We’d rather rebuild that latch than drill it. If the lock body is beyond saving, we quote a replacement before any work starts, in writing, and the price on that paper is the price on the invoice.
Deadbolt Repair in Sunset
Deadbolt repair in Sunset typically costs $95 to $185 for a single-cylinder Residential Locksmith - Sunset unit, with high-security or multi-point deadbolts running higher. The most common failure we see on 1950s through 1970s CBS homes is a seized cylinder. Salt-air oxidation from Biscayne Bay works into the pin chambers, the key gets harder and harder to turn, and eventually it won’t turn at all. We free the cylinder with graphite and non-destructive entry tooling, then re-key it to new key control rather than drilling the face.
Storm-Shifted Frames and Binding Bolts
After a squall line pushes through Sunset, we get calls from homeowners whose deadbolt won’t throw because the door frame has shifted. The bolt scrapes the strike plate and hangs. We reset the frame alignment, file or replace the strike, and test the bolt throw in all three hinge positions. A deadbolt that only works when you lift the handle is a deadbolt that’s about to fail.
HVHZ Impact Door Deadbolts
On post-1992 impact-rated doors, the deadbolt is often integrated into a multi-point system with a central gearbox driving three locking points. Drilling or force-re-keying that cylinder breaks the mechanism seal and can void the door’s windload certification, which Miami-Dade Building officials can flag after a storm inspection. We disassemble instead of drill. Every time.
Trusted Brands We Service in Sunset
We’re factory-authorized to install and service Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware. That means we can re-key a 1962 Kwikset pin-and-tumbler deadbolt on a Kensington Park CBS home and then drive four blocks west to tune a Hoppe multi-point mortise on an impact door near Miller Drive. Because we stock local parts for both hardware generations, most Sunset repairs don’t wait on a parts order. If the cylinder is in our van, the job closes today.
Common Door Lock Repair Problems We See in Sunset Homes
- Salt-air oxidation in 1950s and 60s deadbolts. The original brass strike plates and deadbolt bolts on Sunset’s older CBS stock corrode faster here than in inland Florida. The lock only announces itself as frozen when a storm is bearing down and you’re trying to secure the house.
- HVHZ certification at risk from improper drilling. Impact-rated doors with Hoppe or Fuhr multi-point mechanisms can lose their windload certification if a tech drills the cylinder. Miami-Dade Building can flag that during a post-storm inspection.
- Frame shift from severe weather. Squall lines and hurricane-force wind load can shift steel-framed doors enough to bind the multi-point gearbox. The door feels stuck, but the problem is usually alignment, not the lock itself.
- Worn sliding door latches on impact sliders. Sunset’s post-1992 homes often have heavy glass sliders whose rollers sag over time. The lock doesn’t fail. The door does. We correct both in one visit.

FAQs About Door Lock Repair in Sunset
Yes. We can re-key the cylinder on a Hoppe or Fuhr multi-point impact door without voiding the HVHZ certification, provided the lock body and gearbox are in workable condition. We disassemble the handle set and remove the cylinder without drilling, preserve the manufacturer’s seal, and test every locking point after the job. If the mechanism itself is compromised, we’ll tell you before any work and quote the repair or replacement in writing. Call (910) 714-4287 to schedule.
Usually it’s a salvage and re-key. Salt-air corrosion inside the cylinder is the typical culprit on Sunset’s 1950s to 1970s homes. We free the pins with graphite, clean the cylinder, and cut a new key control set. Replacement happens only if the cylinder body is cracked or the tailpiece has sheared. We’ll tell you which it is before we touch the lock.
Same-day in most cases. After a severe weather event, we prioritize Sunset callouts with door security issues: a door that won’t lock, a frame that shifted, or a damaged cylinder. Call (910) 714-4287 and a live person will give you a realistic arrival window for your part of Sunset, not a chatbot estimate.
Yes. Our local vans stock Schlage and Kwikset pin-tumbler cylinders for Sunset’s original CBS homes, plus tailpieces, strikes, and gearbox components for modern Hoppe and Fuhr multi-point systems on post-1992 impact doors. That dual inventory is standard for our Sunset service route because the housing stock demands it.
We can restore the lock to functional code-equivalent condition on most Sunset sliders, including realignment, strike replacement, and latch rebuild. If the door itself is no longer windload-compliant, that’s a door replacement question, not a lock repair, and we’ll tell you plainly. The lock gets fixed, the certification stays intact, and you get a straight answer either way.
