Fast, Reliable Door Lock Repair Across Inverness
Door lock repair in Inverness typically runs $75 to $210 for cylinder cleaning and re-pinning, with full mortise lock restoration on older cottages usually landing between $180 and $340. Most jobs are done same-day when we’re already in West Marin, and we carry marine-grade hardware because standard lock components fail fast here. If you’re standing at a seized deadbolt off Sir Francis Drake Boulevard right now, call (910) 714-4287 and a live person answers, day or night.
We know Inverness the way a local should. The fog rolling off Tomales Bay does things to locks that inland Marin never sees. Salt residue packs cylinders within a single vacant month. Original 1920s mortise locks seize up and refuse keys that worked fine the year before. Our Door Lock Repair team works on this exact hardware every week, and we stock the parts to fix it properly rather than telling you to replace a door that still has decades of life left.
Why Dunmore Locksmith Is Inverness’s Preferred Door Lock Repair Company
Inverness homeowners call us because we show up with a name, a face, and a written price before the work starts. Perry Osgood leads our crew, and when we dispatch a technician to your cottage off Camino del Mar or near the Inverness Yacht Club, you receive that technician’s name and photo before they arrive. At the door, they show a photo ID badge. The Threshold Standard isn’t a marketing line; it’s how we’ve operated since 2007 under the Threshold Group umbrella. If anyone shows up who you weren’t told to expect, that visit is free.
Our response time to Inverness runs about 45 to 60 minutes for emergency lockouts, and we schedule non-emergency repairs around West Marin routes so you’re not paying for a solo trip from the city. Every repair includes the 365-Day Done Right Promise in writing. If a lock we fixed fails within the year, we return at no charge. That matters here more than anywhere else in Marin, because the coastal environment is genuinely brutal on hardware.
Broken Key Extractor in Inverness
A broken key extractor is the tool we reach for when a key snaps off inside a lock cylinder, usually because the cylinder was already corroded and the key took too much torque. In Inverness, this happens constantly on vacant cottages. An owner or renter arrives after weeks away, finds the deadbolt stiff, forces the key, and it shears clean at the face of the cylinder. The best move is to stop, leave the broken piece in place, and call us. Digging at it with tweezers usually pushes the fragment deeper and turns a $95 to $150 extraction into a $200-plus cylinder replacement.
What Extraction Involves Here
We use a spiral-blade extractor to hook the key fragment between the pins and pull it straight out without damaging the plug. On older Inverness locks with original 1930s or 1940s cylinders, we’ll then test the pin and tumbler stack for salt damage. Often the key broke because the cylinder needed cleaning and re-pinning anyway, and we’ll tell you honestly before doing work beyond the extraction.
When Replacement Makes More Sense
If the key snapped because the cylinder is packed with oxidized brass and corrosion, extraction alone leaves you with a lock that will fail again in months. On marine-exposed doors facing Tomales Bay, we sometimes recommend a direct cylinder swap to a Schlage or Kwikset marine-grade unit at $130 to $220 installed. On a vacation rental that sits empty in fog for weeks, that’s usually the cheaper long-term call.
Sliding Door Lock Repair in Inverness
Sliding door lock repair in Inverness means working on door hardware that gets blasted by salt air from both the bay and the Pacific, often on rentals that lock and unlock constantly for guests and cleaners. The most common failure we see is a latch or lock body corroded into a fixed position, where the key won’t turn and the thumb latch won’t move at all. Repair typically runs $95 to $185 for cleaning, lubrication, and rekeying; full lock replacement on a sliding door ranges $150 to $280 depending on the door’s age and brand.
Bay-Side Corrosion Repairs
Sliding doors facing Tomales Bay take the worst of it. Salt fog penetrates the lock case, rusts the internal springs, and glues the pawl to the strike. We disassemble the lock body, clean every component, and use a dry-film lubricant rated for coastal exposure. Wet sprays like WD-40 just attract more salt and dust, so we avoid them entirely on Inverness jobs.
Warped Track and Strike Issues
On 1940s and 1950s cottages, the problem isn’t always the lock itself. The door frame has absorbed decades of moisture and the sliding panel no longer aligns with the strike. We’ll correct the throw, shim or reset the strike plate, and adjust the rollers if needed. The total on a job like that lands between $140 and $260, and we give you that number in writing before any work begins.
Trusted Brands We Service in Inverness
We repair and install Schlage, Kwikset, and Medeco hardware every day, and we keep factory-authorized parts for these lines stocked on our West Marin trucks. That matters for Inverness because you don’t want to wait a week for a specialty cylinder while your cottage sits unsecured. We also work on original Baldwin mortise locks, which show up constantly in 1920s Inverness homes, and we can re-pin rather than replace those whenever the lock body is sound. If your door has an obsolete cylinder format, we’ll machine or retrofit it rather than butcher the door.
Common Door Lock Repair Problems We See in Inverness Homes
- Salt-seized cylinders on vacant vacation homes. After a few weeks of fog, keys insert but won’t turn, or won’t insert at all. The fix is disassembly, cleaning, and re-pinning, not a new lock.
- Original mortise locks with worn pin stacks. 1910s to 1950s cottages often still have their original mortise bodies. The cylinder format is obsolete, but the lock mechanism itself is built better than most modern replacements. We re-pin rather than replace when the body is intact.
- Warped wood-frame doors binding the bolt. Decades of coastal moisture have swollen original doors, so the deadbolt binds against the strike plate even when the cylinder functions. We adjust the strike, shim hinges, and sometimes plane the door edge slightly.
- Failed vacation-rental key turns from heavy traffic. Rentals cycling through guests and cleaners wear pin stacks faster than owner-occupied homes. When the key gets sloppy or sticks, the pins are often rounded and need replacing before the key snaps off.

FAQs About Door Lock Repair in Inverness
Most 1930s mortise locks in Inverness cottages can be rekeyed without replacement, provided the lock body isn’t cracked and the internal springs still have tension. We disassemble the mortise body, clean the salt residue out of the pin and tumbler stack, and re-pin the cylinder to new keys. If the cylinder itself is an obsolete format and worn beyond re-pinning, we can often machine a new cylinder to fit the existing mortise body rather than replace the whole lock. A full replacement usually only makes sense if the lock body is broken or you want to upgrade to a higher-security cylinder anyway. Call (910) 714-4287 and we’ll tell you honestly which path applies to your door.
That’s salt fog doing what it does. Inverness sits in one of the foggiest salt-air environments in coastal California, and exterior lock hardware stays damp for much of the year. During vacancy, moisture wicks into the cylinder, salt crystallizes on the pins, and oxidized brass grit binds the plug against the housing. The fix is a full disassembly, cleaning, and re-pinning, followed by a dry-film lubricant rated for coastal exposure. We also recommend marine-grade cylinders on bay-facing doors. Call (910) 714-4287 for a written quote before you arrive for your next visit.
Yes, in almost every case. We use non-destructive entry techniques first, including picking and bypass tools appropriate for the lock type. Drilling is a last resort, and we’ll tell you before doing it. We were called to a 1920s cottage off Sir Francis Drake Boulevard near the yacht club where the front door’s Baldwin mortise lock was frozen solid, and our tech gained entry without damaging the original door or lock body. Call (910) 714-4287 and we’ll tell you what we’re likely to do based on your door before anyone is dispatched.
Repair first, almost always. The lock body is a separate component from the door itself, and even heavily corroded lock cases can be disassembled, cleaned, and re-lubricated with dry-film coastal lubricant. If the internal springs have rusted through, we replace the lock body, not the door. The only time a door itself becomes an issue is when the frame has warped so severely that the sliding panel no longer aligns, which we can usually correct with strike plate adjustment and roller work. Call (910) 714-4287 for a repair quote on your bay-side door.
You rekey to a restricted key system. We can pin your locks to a Medeco or Schlage restricted keyway, which means keys can only be duplicated with your written authorization. Pair that with an electronic deadbolt that logs entries, or at minimum rotate key assignments between cleaner, guest, and owner. In Inverness’s rental-heavy market, this is a standard setup we handle regularly. Call (910) 714-4287 and we’ll walk you through the options and a written quote.
