Locksmith in Larkspur, CA
Locksmith work in Larkspur means two very different jobs: a same-day vehicle lockout near the ferry terminal, or a hundred-year-old mortise lock that needs careful hands on Magnolia Avenue. Dunmore Locksmith handles both, with written prices before any work starts and a live person answering the phone 24 hours a day. If you’re locked out, need a lock changed, or want a rekey after a tenant or caretaker leaves, call (910) 714-4287 and you’ll get a real human who can tell you exactly who’s coming and when.
Why Larkspur Homes Are Different
Larkspur’s housing stock splits into two generations that make different demands on a locksmith. Along Magnolia Avenue and the downtown flats, you find Victorian and Craftsman homes from roughly 1885 to 1925. Many still carry original mortise locksets with skeleton-key hardware and brass cylinders that modern lock-replacement approaches will ruin if you force a standard deadbolt into that old door prep. Working on these doors means machining the existing mortise pocket, not ripping it out.
Hillside homes toward Baltimore Canyon and the ridges add another layer: narrow roads, steep driveways, and a mix of mid-century hardware and newer smart-lock installs. Add Marin’s near-daily coastal fog, and you get a real corrosion problem the inland towns don’t feel the same way. Cylinders and deadbolts here collect marine moisture, and wooden door frames swell with the wet season so strikes drift out of alignment. That’s often why a deadbolt won’t throw even when the lock itself is fine. We account for all of it before we touch a door.
Our Main Larkspur Services
Most Larkspur calls fall into two categories: a compromised or inconvenient lock on a home, and commercial hardware for the shops and offices along Magnolia and near the ferry corridor. Each service has its own page with local pricing and detail.
Residential Locksmith in Larkspur
Residential work here starts with a simple question: who needs to get in, and who shouldn’t anymore. For Larkspur’s older homes, that often means rekeying (changing the internal pins so your old keys no longer work) a mortise cylinder rather than replacing a door. For newer hillside builds, we’re more likely servicing a Kwikset or Baldwin deadbolt that’s gone stiff from fog-driven corrosion. Every technician arrives by name and photo, in uniform with a photo ID badge, so you know who’s at the door before you open it. See full residential detail and Larkspur-specific pricing on our Residential Locksmith in Larkspur page.
Door Lock Repair in Larkspur
Larkspur’s climate makes specific repairs routine: seized cylinders from marine moisture, loose strikes on Victorian-era door frames that swell every winter, and worn mortise internals in homes elderly enough to still use their original hardware. We diagnose the lock itself before recommending anything, and the fix is covered by the 365-Day Done Right Promise in writing – if the repair fails, we return at no charge. That’s a guarantee worth having on a Larkspur door that gets daily use. Read about how we handle each repair type on the Door Lock Repair in Larkspur page.
Change Door Locks in Larkspur
Changing locks around here isn’t just a home-security step; it’s often an estate question. Larkspur homes pass between generations, and old skeleton-key locksets on original doors sometimes need a full hardware swap to a modern Schlage or Baldwin while keeping the old door intact. We walk you through whether a change is needed or a rekey makes more sense, and we always put the price in writing before work starts. For a breakdown of what lock changes cost and involve in this area, see Change Door Locks in Larkspur.
Commercial Locksmith in Larkspur
Commercial work in Larkspur runs from the retail strips on Magnolia Avenue to the offices serving ferry commuters near the Golden Gate Ferry Terminal. That means grade-2 and grade-1 commercial levers, high-security cylinders, and master-key systems that hold up to coastal moisture. Dunmore is factory-authorized to service Medeco and Yale hardware, so we can handle commercial cylinders most subcontractors can’t. For surveyed and scheduled commercial work, see Commercial Locksmith in Larkspur.

What Larkspur Customers Say
"Deadbolt on the front door was sticking and wouldn't throw all the way. He cleaned it, adjusted the strike plate, and it works smoothly now. Charged very little."
- Victor S."The fact that he was background checked and carried ID made me comfortable letting him into the home. Changed out two worn deadbolts for new grade 1 ones."
- Brenda Z."We moved into a new house and wanted to know nobody else had a key. He rekeyed every exterior door and showed me how the pins work. Clear and patient."
- Anita P.
