Dunmore Locksmith has served Marin County’s waterfront and hillside communities since 2007, and we know what Tiburon’s salt-laden air does to door hardware.

For a free quote on any lock repair, rekey, or smart-lock install in Tiburon, call (910) 714-4287.
Why Dunmore Locksmith Is Tiburon’s Preferred Residential Locksmith Company
Tiburon homeowners call us for one simple reason: we tell you exactly who is coming to your door, what the work will cost, and we put both in writing before anything begins. The Threshold Standard is the name for how we vet our people. Every technician is background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. When the doorbell rings, the face at your door matches the face on your phone. Period.
We also know Tiburon’s housing stock in a way a Tiburon Commercial Locksmith competitor does not. Homes along Tiburon Boulevard, the hillside lanes above Richardson Bay, and the newer rebuilds near Paradise Drive each have their own lock problems. Older mortise locks, salt-corroded cylinders, warped doors on 1970s hillside builds: these are the calls we answer every week. And since 2007, our work has been backed by the 365-Day Done Right Promise. If a repair fails within a year, we return at no charge. Written guarantee, every job.
Perry Osgood, who leads our team, has built Dunmore’s reputation around one idea: a locksmith should be the safest stranger you ever open your door to. That’s why our prices are delivered in writing before work starts, with no call-out surcharge added on arrival. What you’re quoted is what you pay.
Locksmith Key Replacement in Tiburon
Locksmith Key Replacement in Tiburon means cutting and programming new keys when originals are lost, stolen, broken off in the cylinder, or simply worn smooth from years of salt grit and daily use. We handle basic residential key cutting, high-security key duplication, and transponder-free replacement for most Tiburon home locks. For a standard Schlage or Kwikset key replacement, you’re looking at roughly $5 – $15 for a basic cut, and $25 – $65 when the job also requires rekeying the cylinder so the old key no longer works.
When Rekeying Is the Real Fix
If you’ve lost a key or had one go missing, rekeying is almost always the right call. We change the internal pins so your old keys stop working, cut new keys to match, and you keep the existing hardware. For a standard knob lock or deadbolt in Tiburon, rekeying typically runs $20 – $45 per cylinder, with most homes needing two to four cylinders done.
When the Cylinder Itself Is Shot
Here’s the honest part. If the cylinder on a waterfront home has been saturated by bay air and salt fog for a decade, the pins may be rusted and the keyway galled. A rekey in that condition won’t last. You need a new cylinder, and on some older mortise locks, that means swapping the entire lock body. We’ll tell you which situation you have before you spend a dollar, and the price goes in writing first.
Smart Lock Installation in Tiburon
Smart Lock Installation in Tiburon has become one of our most common requests, particularly among part-time residents and property owners who manage housekeepers, contractors, and weekend guests remotely. A keypad entry lock or app-controlled deadbolt means you never have to hide a key under a planter on a hillside deck again. For most homes, installing a Schlage Encode, Yale Assure, or Kwikset Halo smart lock runs $175 – $350 in labor, plus the cost of the hardware, which typically runs $180 – $400 depending on the model and finish.
Why Part-Time Residents Choose Keypads
Tiburon has an unusual number of second-home and weekend owners. People fly in Friday night, leave Sunday, and someone else manages the house in between. Keypad entry solves the recurring problem of a guest or cleaner showing up to a stiff, salt-fogged lock they can’t open. We retrofit existing deadbolts or install new ones and connect them to your home Wi-Fi, with backup key access for San Francisco Bay-area power outages that knock out routers.
Older Doors and Smart-Lock Fit
A 1970s original door on a hillside ranch home doesn’t always accept a modern smart deadbolt without prep work. The bore may be off-center, the strike plate worn, or the door itself warped enough to bind. We handle door prep and wrap plates so the new lock operates smoothly, and we’ll tell you before any cutting starts what the total cost will be.
Trusted Brands We Service in Tiburon
We carry and service the hardware Tiburon homes actually have installed. That means Schlage and Kwikset for daily deadbolts, Yale for smart locks and keypad entry, and Medeco for the high-security cylinders many waterfront estate owners choose. Because we stock common Schlage, Kwikset, and Yale parts on our service vehicles, most replacements in Tiburon are completed in one visit, not two. We won’t sell you a brand we don’t trust, and we won’t install a lock we wouldn’t put on our own door.
Common Residential Locksmith Problems We See in Tiburon Homes
- Salt corrosion seizing cylinders on waterfront homes. The constant marine air off Richardson Bay deposits salt inside lock cylinders. A lock that turned fine in October may be rigid and gritty by February. This is the single most common failure we see along Tiburon Boulevard and the bay-facing hillside lanes.
- Warped original doors on 1970s and 1980s builds. Mid-century hillside homes settle. Doors twist. A new deadbolt dropped into a warped door will bind inside a month. We repair or prep the door before installing new hardware.
- Mortise locks nobody has serviced in decades. Many older Tiburon homes still have original mortise lock bodies. They’re heavy, solid, and often neglected until the day they freeze. Some can be rebuilt. Some need replacement. We’ll tell you which.
- Weekend owners finding changed locks they didn’t approve. Housekeepers, contractors, or property managers sometimes rekey a cylinder and forget to tell the owner. You fly in Friday night and your key no longer works. We get you in, then rekey everything to one new key so every door matches again.

FAQs About Residential Locksmith in Tiburon
It depends on whether the corrosion is inside the cylinder or inside the lock body. If the pins are rusted and the keyway is galled, a rekey won’t save it, and we’ll tell you that plainly. If the internal pins are still clean and the stiffness is just surface salt on the face, we can often clean it, re-lubricate with a marine-grade product, and rekey it. We’ll inspect before we recommend anything, and the quote for either path is in writing before work starts. Call (910) 714-4287 and we’ll give you an honest read on the phone.
You don’t need one, but if you have a housekeeper, contractor, or weekend guests arriving while you’re in San Francisco, it solves the single most common lock problem for part-time Tiburon owners: someone shows up and can’t get in. A keypad retrofits onto most existing deadbolts and eliminates hidden-key and lockout calls entirely. It’s a one-time cost that pays for itself the first time your property manager doesn’t call you at midnight.
Yes, in almost every case. We re-pin the cylinders so one key operates every lock on the property, as long as the cylinders share the same keyway type. If you have a mix of old mortise cylinders and newer Schlage or Kwikset hardware, we may need to replace one or two cylinders to make a single key work. Most Tiburon homes we service are on one key within the hour.
Salt air is the difference. Tiburon is a peninsula with San Francisco Bay on three sides, and the prevailing marine layer settles salt into exposed lock faces on waterfront and hillside homes. San Rafael sits farther from the open bay and gets far less salt deposition. The result is that Tiburon locks corrode faster, seize sooner, and need replacement years before an identical lock a few miles inland. It’s a real thing, and it’s the reason we stock more corrosion-resistant cylinders for Tiburon jobs than for inland Marin work.
We carry Medeco and Schlage high-security cylinders for homes that want bump-resistant, pick-resistant, and restricted-key hardware. Medeco keys can only be duplicated by authorized dealers with your signed card, which means nobody can quietly copy a key and keep access. For waterfront estates and high-value properties in and around Belvedere and Tiburon, these cylinders are the standard we recommend. We also service Mul-T-Lock and Abloy for clients who already have those systems installed.
