Before
AfterLocksmith in Larkspur, CA
Locksmith work in Larkspur, CA usually costs between $95 and $350 depending on the job, with most residential calls falling in the $120 to $220 range. What makes Larkspur different from neighboring Marin towns is the mix: older wooden doors with decades of settling, hillside homes with non-standard entry hardware, and a spread of commercial storefronts along Magnolia Avenue. If you’re locked out or need a lock changed, call (956) 275-7388 and a live person answers, day or night.
We’re Ridley Locksmith & Security, and we’ve operated under The Garrison Standard since 2007. That means every Larkspur job gets a written price before work starts and a written guarantee that covers the repair for one full year. Drew Kowalski leads our team, and the technicians who show up at your door are background-checked, uniformed, and dispatched locally from our Bay Area office.
Why Larkspur Homes Are Different
Larkspur’s housing stock runs older than most of Marin. Many homes in the flats around downtown were built in the 1940s and 1950s. Walk through the neighborhood south of Sir Francis Drake Boulevard and you’ll see original redwood doors, brass mortise locksets, and entry hardware that’s been painted over four or five times. Those doors settle. Frames shift with winter rain and summer dry spells, which means latch alignment is a constant issue. A deadbolt that worked fine in June may bind against the strike plate by January.
The hillside streets above Magnolia Avenue add another layer. Steep driveways, narrow stairways, and some homes with multiple entry points at different levels. It’s not unusual to find a front door, a garage entry, and a lower-level door that all key differently because previous owners added hardware piecemeal over the years. That’s where rekeying becomes the smart play: one key for the whole property without replacing valuable Baldwin or Schlage hardware that’s lasted this long. The terrain also makes it harder to work in a hurry. We send techs who know how to handle a hillside property without damaging doors, trim, or patience.
Our Main Larkspur Services
Most Larkspur homeowners call us for one of two things: changing key control after a move or a lost key, and securing the home with hardware that actually fits the existing prep. Commercial property managers and shop owners on Magnolia Avenue call for access control and master key work. Here’s how each breaks down in Larkspur.
Rekey Locks in Larkspur
Rekeying means changing the internal pins inside a lock cylinder so the old keys stop working, without replacing the hardware itself. In Larkspur, this matters because so many homes have solid brass or bronze hardware worth keeping. We rekey Schlage, Kwikset, Yale, and high-security lines like Medeco and Mul-T-Lock. If you’ve bought a Larkspur home or had a cleaner, tenant, or contractor with a key, rekeying is the fastest way to reset who can get in. One service call, one written price, all locks keyed alike. See the full detail on our Rekey Locks in Larkspur page.
Residential Locksmith in Larkspur
Residential work in Larkspur runs from deadbolt installation and door reinforcement to entry door hardware replacement and rekeying. Older doors here often have shallow bore holes and oversized strike cutouts, so we carry strike plates and longer screws that actually anchor into the frame. When a Medeco or Baldwin lock needs service, we handle it on the spot because our techs are trained on high-security hardware, not just entry-level brands. That matters more in Larkspur than people expect. Full detail: Residential Locksmith in Larkspur.
Commercial Locksmith in Larkspur
Larkspur commercial work is concentrated along Magnolia Avenue, in a handful of office buildings near the ferry terminal, and in small retail clusters. These jobs are different from residential: master key systems, high-security cylinders, and regular rekeying when employees leave. Because commercial work is scheduled and surveyed rather than dispatched blind, we quote a flat per-lock price after a walkthrough. If you need a master key system planned for a Larkspur building, we’ll write the scope before any work starts. See the Commercial Locksmith in Larkspur page.

Larkspur pricing shifts a little with terrain. A hillside home at the end of a long set of stairs adds a few minutes of labor, and older doors with non-standard bore sizes sometimes need minor carpentry before new hardware seats correctly. But the price we quote on the phone includes that. There’s no dispatch fee added on arrival, and the written price stands. If the repair fails within one full year, we come back at no charge. That’s the 365-Day Done Right Promise, and it applies to every Larkspur job.
