Medeco Locksmith in San Francisco, CA | Strongbox Lock & Safe Co. of California
Medeco lock repair and rekeying in San Francisco typically runs $180-$420 depending on cylinder count and master-key complexity, with most single-cylinder jobs completed same day. What sets our Residential Locksmith in San Francisco apart is the pairing: we stock genuine Medeco Biaxial and Keymark parts for Victorian mortise installations that most locksmiths outside the city never encounter, and we understand how the Pacific fog degrades west-facing hardware differently than anything inland. Call (833) 294-4584 for a flat price before we dispatch.
Why San Francisco Residents Choose Us for Medeco Service
We’ve been working on Medeco hardware in San Francisco for over 42 years. Gil Sanderson, our owner, learned this trade at Los Angeles Trade-Technical College and spent his teens sorting key blanks in his father’s hardware shop. That background matters when you’re standing in front of a 1910 Edwardian mortise lock in Nob Hill trying to match a Medeco M3 cylinder to a strike pocket cut for a 1-inch deadbolt throw.
We’re an independent Medeco service provider, not a factory-authorized dealer. That distinction matters less than you’d think. Our senior technicians hold manufacturer-level certifications from Medeco’s training programs, and we stock thousands of Medeco biaxial and keymark parts at our San Francisco facility. We don’t wait on authorization calls from Virginia. If your Medeco cylinder is seized in the Outer Richmond, we fix it that day.
Every technician is background-checked, uniformed, and presents ID at your door. We quote a flat price on the phone before the truck rolls. Every job carries our 90-Day Done Right Promise in writing. If it isn’t right, we come back. No paperwork, no arguing.
Common Medeco Locksmith Problems We Solve in San Francisco
- Salt-fog corrosion jams Biaxial rotating pins. The marine layer rolling in off Ocean Beach deposits salt on west-facing hardware faster than anywhere else in the Bay Area. We’ve replaced dozens of Biaxial cylinders in the Sunset and western Richmond where the pin chambers have corroded to the point of seizure. Disassembly, cleaning, and repacking with marine-grade grease solves it. Standard lubricants won’t last a season here.
- Original M3 sidebar springs fail on Victorian front doors. In Nob Hill and Russian Hill, the M3 cylinders installed during 1980s and 1990s upgrades have reached end-of-life on their sidebar springs. The key binds intermittently, then stops working entirely. We replace with Biaxial cores pre-cut to your existing keys, preserving your master system without new keying.
- Keymark cylinders seize in SoMa commercial roll-ups. The converted warehouse buildings in 94103 and 94107 expose rim cylinders to street-level grit that flush-lubricant can’t reach. We swap to sealed-weather Keymark models that keep contaminants out of the pin chamber.
- Mortise deadbolts won’t fully throw in swollen fir frames. San Francisco’s old-growth fir door frames absorb moisture from the fog and expand seasonally. The lock mechanism is fine. The door alignment is wrong. We diagnose this constantly in the Mission and Tenderloin, saving customers from unnecessary cylinder replacement.
- Master systems need rekeying between tenancies. California Civil Code §1950.5 requires it. With San Francisco’s rental density and Ellis Act turnover, landlords in the Mission and Civic Center call us regularly to re-pin entire Medeco master systems. We stock the OEM pins, sidebars, and master wafers to do it in one visit.
Medeco Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s 1906 earthquake rebuilding codes required mortise locks with deadbolts having at least a 1-inch throw, and many original Medeco upgrades were installed to meet that spec. Our techs carry the deep-throw mortise deadbolts still sold by Medeco to match those old strike pockets. This isn’t a catalog preference. Walk into a hardware store in Sacramento or Fresno and ask for a Medeco mortise deadbolt with 1-inch throw for a 1909 Victorian, and you’ll get a blank stare. In San Francisco, it’s standard stock.
The fog off Ocean Beach degrades standard zinc-alloy cylinders to failure within three to five years. Locksmiths in the Outer Sunset and western Richmond spec marine-grade or solid-brass exterior hardware as a matter of course. Hardware considered an unnecessary upgrade almost anywhere else. We learned this the hard way in our early years. Callbacks for seized locks taught us to ask which way the door faces before we quote.
We rekeyed a Medeco Biaxial master system for a 12-unit Victorian flat in the Mission at 24th & Guerrero where the landlord needed 36 operating keys after an Ellis Act turnover. Our tech removed all 12 lock cylinders, re-pinned every core with new Medeco OEM pins and sidebars to a custom master wafer, and reinstalled within 90 minutes without any drilling. That kind of volume turnaround is routine here. It would be exceptional anywhere else.

We work on the full Medeco residential and commercial line: Medeco sales & service includes Biaxial, Keymark, Original (M3), and Medeco 32 systems.

When corrosion has pitted the housing beyond economical repair, we replace with a new Biaxial or Keymark core keyed to your existing master system.
Our Commercial Locksmith - San Francisco van stocks the deep-throw mortise deadbolts, marine-grade cylinders, and master-key components that Victorian flats and fog-exposed west-side buildings require.

FAQs - Medeco Locksmith in San Francisco
The salt-laden marine fog off Ocean Beach corrodes standard zinc-alloy cylinders faster than inland climates. We spec marine-grade or solid-brass Medeco hardware for west-facing doors, which extends service life dramatically. Call (833) 294-4584 and we’ll quote replacement with the right grade for your exposure.
Yes, if both systems use compatible keyways and pinning specifications. Our techs carry the master wafers and sidebar components to integrate Keymark into existing Biaxial master systems. We’ll confirm compatibility when you call (833) 294-4584 for a free estimate.
California law obligates landlords to rekey between tenancies, not tenants. If you’re the property owner or authorized manager, yes. If you’re a tenant, your lease likely requires landlord coordination. We work with both parties regularly and can document the rekey for your records.
We can generate new keys from the existing M3 cylinder code, or if the sidebar springs have failed, we replace with Biaxial cores pre-cut to match. The mortise pocket and 1-inch throw strike are preserved. Most Nob Hill jobs like this finish in under an hour.
The locks handle it fine. The door frames don’t. Swollen old-growth fir shifts alignment so latches bind or deadbolts won’t fully throw. We diagnose this constantly in San Francisco. Often the fix is strike adjustment or hinge realignment, not lock replacement. Call (833) 294-4584 and we’ll sort out whether it’s the lock or the frame before quoting.
