Fast, Reliable Door Lock Repair Across Key Biscayne
Door lock repair in Key Biscayne typically runs $95 – $260 for common jobs like cylinder replacement, latch adjustment, or strike realignment. Most calls are completed same-day, though the island’s salt-air corrosion often means a “simple” repair involves replacing internal components rather than just lubricating them. We answer live 24 hours a day at (910) 714-4287, and every job includes a written price before work begins. If you’re on Crandon Boulevard, in a condominium near the Village, or out by Cape Florida, we get to you across the Rickenbacker Causeway with the right hardware already on the truck.
Why Dunmore Locksmith Is Key Biscayne’s Preferred Door Lock Repair Company
Key Biscayne homeowners keep calling us back because we understand what salt air does to door hardware on a barrier island. A lock that works fine in Coral Gables can seize solid within 18 months here in Key Biscayne. That local knowledge is why our Door Lock Repair technicians carry marine-grade replacement parts that mainland locksmiths often don’t stock.
Every technician we send to Key Biscayne is background-checked, identity-verified, and photo-badged under The Threshold Standard. Before the visit, you get the technician’s name and photo by text or email. When they arrive at your door near Crandon Park or in a high-rise on Ocean Drive, they show a photo ID badge. You know exactly who you’re opening the door to before you turn the handle. That matters on an island where many residents live alone or with young children.
We’ve served the Key Biscayne community since 2007 as part of the Threshold Group family. Our phones are answered by a live person at 2 a.m. or 2 p.m., not a voicemail. Every repair carries the 365-Day Done Right Promise: if the repair fails within a year, we return at no charge. Written, in hand, stamped on the job.
Broken Key Extractor in Key Biscayne
Broken Key Extractor work in Key Biscayne is more common than most people expect because salt corrosion weakens the key blade itself, especially brass keys carried in pockets near the beach or on boat docks. When a key snaps off inside the cylinder, standard removal runs $85 – $150. But in Key Biscayne, we always inspect the cylinder before quoting the extraction, because if the pins have already oxidized, the extractor job often exposes the need for a cylinder replacement too. That honest inspection prevents an underpriced job that turns into a surprise later.
When the Key Breaks and the Cylinder Is Fine
We use a thin extraction tool with a hooked tip to grip the broken key blade and pull it out without damaging the plug. Once it’s out, we test the cylinder with a fresh key. If it turns smoothly, you pay only the extraction and a new key if you want one cut on site.
When Salt Has Already Compromised the Cylinder
On bay-facing doors in Key Biscayne, the broken key is often the symptom, not the whole problem. Salt air works its way into the pin chambers over months and years. Once the plug resists turning even after extraction, the honest fix is a new cylinder, usually $120 – $190 for a quality Kwikset or Schlage replacement. We always quote the full job before cutting anything.
Sliding Door Lock Repair in Key Biscayne
Sliding Door Lock Repair in Key Biscayne almost always involves corrosion in the thin metal housing that holds the sliding glass door’s latch. These housings are typically zinc die-cast, and Key Biscayne’s salt air cracks them within one to two years on ocean-facing units. A typical sliding door lock repair here runs $110 – $210 depending on whether the existing mortise-style lock can be salvaged or needs a full replacement assembly.
Adjustment and Lubrication Before Replacement
Sometimes the sliding door just doesn’t align because the rollers have sagged or debris has crusted in the track. We clean the channel, adjust the door height, and lubricate the latch with a dry marine lubricant. That service starts at $95.
Marine-Grade Replacement Hardware
When the zinc housing is cracked or the hook has sheared, we replace the entire lock assembly with stainless or marine-rated hardware. On Key Biscayne, that’s the difference between a repair that lasts five years and one that fails again in 18 months. We keep common sliding door lock bodies in the truck so a single visit usually finishes the job.
Trusted Brands We Service in Key Biscayne
Dunmore Locksmith is factory-authorized on the hardware Key Biscayne homes already have and on what we recommend for coastal life. We service and install Kwikset, Schlage, Medeco, Baldwin, Yale, and Mul-T-Lock. For Key Biscayne specifically, we recommend Medeco’s stainless cylinders for bay-facing entry doors and Baldwin’s marine-grade marine brass for luxury estates where appearance matters as much as function. We hold local stock of the most common replacement parts for these brands, so a Key Biscayne job rarely waits on a mainland parts run.
Common Door Lock Repair Problems We See in Key Biscayne Homes
- Seized cylinders from salt-air oxidation. Brass pin-and-tumbler cylinders turn green and the pins bind inside the chambers. What would be a $40 rekey on the mainland becomes a $120 – $190 cylinder replacement in Key Biscayne once the plug cannot be removed without drilling.
- Cracked zinc die-cast strike plates and housings. Ocean-facing doors take the worst of it. The zinc corrodes, swells, and cracks, usually within two years. We replace with marine-grade stainless.
- Corroded master key systems in older condos. In the 1970s low- and mid-rise buildings along Crandon Boulevard, decades-old master key pins have oxidized into place. Plug removal often requires drilling, so we always inspect before quoting a rekey on these systems.
- Impact-rated door lock misalignment. Post-Hurricane Andrew multi-point locking systems on Key Biscayne estates shift as the building settles or the heat cycles warp door frames. The rods and latches then bind, and the repair usually requires realigning the door, not just lubricating the lock.

FAQs About Door Lock Repair in Key Biscayne
Key Biscayne is a barrier island completely surrounded by Biscayne Bay and the Atlantic, so your locks are exposed to constant salt-laden air that Coral Gables, 8 miles inland, never sees. Brass cylinders oxidize green, zinc components crack, and internal pins bind within one to two years on a bay-facing or ocean-facing door. Call (910) 714-4287 and we’ll inspect the hardware and replace it with marine-grade parts where needed.
It depends on the cylinder’s internal condition, which we inspect before quoting. If the pins still move freely, rekeying a standard knob or deadbolt in Key Biscayne runs $60 – $95 per cylinder. If the plug has oxidized so badly it cannot be removed without drilling, replacement runs $120 – $190. We’ll tell you which one you need before any work starts.
Often yes, but not with a rekey alone. In older Key Biscayne condos, the master pins and cylinders have typically corroded into place. Repairing these systems may require drilling out seized plugs and replacing cylinders individually. We handle master-key systems in condominiums throughout Key Biscayne, but we always inspect first and give you a written scope and flat per-lock price before scheduling the work.
Medeco stainless-steel cylinders and Baldwin marine-grade brass hold up longest on Key Biscayne door hardware. For sliding doors, we recommend marine-rated stainless latch assemblies rather than factory zinc housings. Kwikset and Schlage offer good mid-range options if you commit to annual cleaning and lubrication. We keep all of these on the truck for same-day Key Biscayne repairs.
No. The price you get on the phone before dispatch is the exact price on the invoice, and it includes the causeway crossing. We schedule Key Biscayne calls in blocks to keep response times short, but there is never a toll surcharge or a “trip fee” added when we arrive.
