We’ve worked San Anselmo’s streets for decades. From the creek-adjacent blocks downtown to the hillside Craftsman clusters off Center Boulevard and the Victorian cottages lining San Francisco Boulevard, we know the doors, the hardware, and the problems this town throws at locks. The fog that funnels up San Anselmo Creek doesn’t just make mornings gray - it corrodes brass cylinders and swells wooden jambs in ways you don’t see in drier Fairfax or sun-exposed Kentfield. That local knowledge saves you a return visit.
Why Strongbox Lock & Safe Co. of California Is San Anselmo’s Preferred Lock Installation & Rekey Company
Our reputation in San Anselmo was built one door at a time. Homeowners here talk to neighbors. They remember who showed up on time, who quoted a real price, and who came back when the strike plate needed tweaking after the jamb settled. That steady word-of-mouth matters more in a town of 12,000 than any ad campaign.
We answer calls live, 24/7 - including nights, weekends, and holidays. No voicemail trees. When a San Anselmo Creek flood leaves your deadbolt misaligned at 10 PM, you reach a person who dispatches a background-checked, uniformed technician with ID. The price we quote is the price on the invoice. Period.
Our 90-Day Done Right Promise covers every job in writing. No paperwork to file, no argument to have. If it is not right, we come back. After 42 years serving local communities, we plan to be here in thirty more. That is why we do not cut corners on a lock that should last twenty years.
Our Lock Installation & Rekey Services in San Anselmo
Smart Lock Installation
San Anselmo homeowners increasingly want keyless convenience without sacrificing the character of their 1920s entry doors. We install Schlage Encode, Yale Assure, and Kwikset Halo units specifically selected for retrofitting older jambs - the kind with non-standard backsets and thinner stiles common in pre-war Craftsman construction. Our Lock Installation & Rekey team measures on-site, confirms Wi-Fi reach through San Anselmo’s typical plaster-and-lath walls, and programs everything before we leave. Most smart lock installations in San Anselmo run $280-$450 including hardware.
Electronic Lock & Keypad Entry
Electronic deadbolts with keypad entry suit San Anselmo rental properties and accessory dwelling units particularly well - no rekeying between tenants, no lost keys floating around. We favor Medeco and Schlage electronic models with marine-grade finishes for creek-facing homes where standard electronics corrode in two seasons. Installation on a standard prepped door runs $220-$380. For original mortise doors, we machine adapter plates in-house rather than forcing a modern cylinder into vintage hardware.
Biometric Lock Installation
Fingerprint entry appeals to San Anselmo’s aging-in-place homeowners who no longer want to fumble for keys on dark, foggy evenings. We install biometric models from trusted manufacturers with capacitive sensors that work reliably in the damp microclimate of the creek valley - not the cheap optical units that fail when your fingers are cold or moist. These installations start at $340 and require a solid-core door or reinforced jamb, which we assess during your free estimate.
Key Duplication
Our mobile vans carry precision duplicators and the full range of key blanks for San Anselmo’s mixed housing stock: standard Schlage and Kwikset KW1s for post-1960 additions, skeleton-key blanks for original mortise locks, and high-security Medeco and Abloy blanks that box stores cannot copy. Most duplicates are cut while you wait during a service call. High-security key duplication runs $18-$35 per key, with the original authorization verification we perform to protect your key control.

Trusted Brands We Service in San Anselmo
We stock and install Schlage, Medeco, Kwikset, and Abloy hardware on our San Anselmo vans - not because they are the only names, but because they are the right names for this town’s doors. Schlage’s commercial-grade B60N deadbolt handles the rekeying frequency of multi-generational homes. Medeco’s restricted keyways protect the jewelry makers and small professional offices along San Anselmo Avenue. Kwikset’s SmartKey technology lets homeowners rekey themselves after a contractor or caregiver departs. Abloy’s rotating disc cylinders resist the corrosion that kills standard pin-tumbler locks in fog-exposed creek properties. We do not sell what we would not install on our own doors.
Common Lock Installation & Rekey Problems We See in San Anselmo Homes
- Original mortise locks binding from hillside soil movement. San Anselmo’s clay-heavy terrain shifts seasonally, racking door frames on hillside lots off Sir Francis Drake Boulevard and Summit Avenue. The mortise lock body - original equipment in most pre-1940 homes - was never designed to tolerate a twisted stile. We diagnose whether the lock, the frame, or both need attention.
- Waterlogged frames from creek flooding misaligning deadbolts. San Anselmo Creek’s recurring flood events inundate the downtown corridor and adjacent residential streets. Wooden door frames swell out of true. Deadbolts and latches bind. On the blocks closest to the creek, we bring strike-plate shims and 3-inch screws on every call - what looks like a simple rekey often turns into jamb realignment before the door will close and latch correctly again.
- Marine fog corroding pre-WWII brass and cast-iron hardware. The persistent moisture funneled up San Anselmo Creek accelerates oxidation on exterior lock hardware. Original skeleton-key locks and early Baldwin deadbolts seize solid. We can often free and rekey these cylinders, but when the casting itself is compromised, we source period-appropriate replacements from specialty suppliers rather than forcing modern hardware onto vintage doors.
- Post-flood lock cylinder replacement on creek-facing properties. Prolonged moisture exposure destroys pin tumblers and springs. After wet winters, calls spike from the blocks between Creek Road and the water. We replace with corrosion-resistant components and can upgrade to marine-grade finishes where the exposure repeats.

FAQs - Lock Installation & Rekey in San Anselmo
Rekey within 48-72 hours if your lock cylinder was submerged or exposed to prolonged moisture. Water displaces lubricants, corrodes pins and springs, and introduces grit that accelerates wear. Last winter after a creek flood, we rekeyed a mortise lock on a Craftsman bungalow on Center Boulevard. The original Baldwin deadbolt had seized from moisture, and the swollen jamb required 3-inch screws and shims to realign the strike plate before the door would latch. Call (833) 294-4584 - we prioritize flood calls and can often same-day the creek-adjacent blocks.
Yes, we install smart locks on Craftsman and Victorian doors weekly - but it requires specialized fitting, not a box-store install. Older doors have thinner stiles, non-standard backsets (often 2-3/8″ or mixed), and mortise pockets that conflict with modern deadbolt footprints. We machine custom adapter plates and select low-profile smart locks designed for retrofit applications. The job typically runs $280-$450 and is done in one visit.
We can often free and rekey a seized skeleton-key mortise lock if the casting and boltwork are intact. About sixty percent of the time, disassembly, corrosion removal, and new pin stacks restore function. When the case is cracked, the bolt is worn paper-thin, or the keyway is damaged beyond pinning, we source period-appropriate replacement mortise locks from specialty suppliers - not the cheap imports that throw off your door’s proportions. We assess this on-site during your free estimate.
The combination of San Anselmo’s fog-channeling creek valley and clay-heavy hillside soil causes two distinct failure modes: marine moisture corrodes exterior cylinder components, and seasonal soil movement racks door frames out of square. The deadbolt binds against the misaligned strike plate or seizes internally from oxidation. We address both - rekeying or replacing the cylinder, then realigning the jamb and strike plate so the bolt throws smoothly year-round.
Yes, we rekey and install hardware for the small professional offices, retail spaces, and service businesses along San Anselmo Avenue and the downtown corridor. These creek-adjacent commercial properties face the same post-flood frame swelling and corrosion issues as residences, often with higher traffic demanding more durable hardware. We stock commercial-grade Schlage and Sargent leversets with clutched mechanisms that withstand heavy use, and we rekey master-key systems when staff turnover requires it. Call (833) 294-4584 for commercial pricing - estimates are free.
