Medeco Locksmith in San Francisco, CA | Loxley Locksmith & Security
We provide independent Medeco sales, service, and rekeying across San Francisco’s neighborhoods, from the fog-belt Victorians of the Outer Sunset to the Edwardian flats of the Mission. The one thing that makes our Medeco work here different: we understand how San Francisco’s salt-laden marine air, century-old mortise hardware, and rent-control turnover laws create failure modes you won’t find in a standard Medeco manual. Call (682) 281-8985 for a free estimate - we quote the full price before dispatch, and that’s the price on the invoice.
Why San Francisco Residents Choose Us for Medeco Service
We’ve been inside enough San Francisco buildings to know the difference between a Medeco cylinder that’s actually failed and one that’s just fighting its housing. Sam Rourke, our owner, cut his teeth on high-security hardware at Los Angeles Trade-Technical College, then spent years rekeying stripped deadbolts and rebuilding commercial master key systems across Los Angeles before bringing that same approach to our San Francisco service area. He started Loxley because he was tired of watching property owners get sold hardware they didn’t need by technicians who vanished before the paperwork cleared.
We’re not an authorized Medeco dealer, and we don’t pretend to be. That independence matters. It means when we open your Medeco Maxum or M3 cylinder, we’re looking at what’s actually wrong - not running down a checklist that ends with “replace everything.” We stock genuine Medeco OEM pins, restricted key blanks, and replacement cylinders for M3, Biaxial, Maxum, and KeyMark lines. When the body and sidebar are sound, we repin and rebuild. When they’re not, we tell you straight.
Every job follows The Kingswell Way: say the price before the work starts, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. Our 365-Day Done Right Promise covers parts and labor - if a repair fails inside that year, we fix it at no charge. No promotion, no upgrade fee. A good lock shouldn’t need a sales pitch.
Common Medeco Locksmith Problems We Solve in San Francisco
- Fog-belt corrosion seizing cam mechanisms in the Outer Sunset and Outer Richmond. The marine layer here carries salt-laden humidity that attacks deadbolt internals faster than anywhere inland. We’ve opened Medeco cylinders that still turned freely but couldn’t throw the bolt because the cam was frozen with corrosion. This shows up in buildings barely ten years old - a purely coastal failure mode.
- Misaligned retrofits in Victorian mortise bodies across the Mission and Haight. Pre-1906 and Edwardian-era mortise lock cases weren’t machined for modern high-security cylinders. When a Medeco Biaxial or M3 is forced into an original mortise body, the pin chamber sits at a slight angle. Keys start feeling gritty within a year. Pins wear unevenly. We see this constantly in the city’s densest flat neighborhoods.
- Restricted-keyway control breakdowns during SF Rent Ordinance turnovers. Landlords need documented rekeys at every tenancy change. If the restricted-key card or original key blanks are missing, we can’t simply duplicate. The cylinder comes out, gets repinned or replaced, and new keys are issued on a fresh restricted card - with the written record the ordinance demands.
- Biaxial slider and sidebar wear on heavily trafficked building entries. In San Francisco’s typical three-unit vertical flat, one Medeco system often controls the street gate, building entry, and unit doors. The building entry cylinder sees 3x the use. Sliders wear, sidebars lose tolerance, and the key starts catching halfway through its rotation - while the unit doors still operate smoothly.
- Accelerated pin wear from salt corrosion plus misalignment. The worst cases combine both problems: a fog-corroded cylinder already struggling, installed in a mortise body that never held it straight. Pins gall, springs fatigue, and the keyway develops slop. We’ve rebuilt these when possible and replaced them when the body was too far gone.
Medeco Service in San Francisco: What Local Conditions Mean for Your Equipment
The San Francisco Rent Ordinance creates a locksmithing rhythm here that doesn’t exist in Daly City, San Mateo, or San Jose. Every tenancy turnover triggers a legally driven demand for documented lock changes - not just rekeyed, but recorded. For Medeco owners, this means restricted-keyway systems need active key control with every tenant change, not just when someone loses a key. A property manager in the Haight called our San Francisco Commercial Locksmith team about a three-unit Victorian flat where the street gate, building entry, and one unit door all ran on a single Medeco M3 restricted system, and the tenant was moving out under a Rent Ordinance turnover. Our tech pulled the Maxum cylinder at the building entry, found salt-corroded cam and worn Biaxial sliders, repinned with OEM Medeco parts, and reissued keys on the existing restricted card. The manager got the rekey completed and the written record the ordinance requires, without replacing the whole system. That’s the pattern we see across San Francisco’s rent-controlled housing stock - ordinance rekeys paired with genuine Medeco key control, done with paperwork that holds up if anyone asks.
Medeco Models & Products We Service in San Francisco
We carry stock and service experience across the full Medeco residential and commercial range. Our Medeco sales & service covers:
- Medeco Maxum deadbolt - the residential high-security standard, often retrofitted into San Francisco’s older doors
- Medeco deadbolt with Biaxial cylinder - still common in buildings from the 1990s and 2000s; slider and sidebar wear is our typical call
- Medeco KeyMark / KeyMark XT - commercial and multi-unit cylinders, frequently master-keyed in San Francisco’s larger flat buildings
- Medeco Medeco3 (M3) - restricted-keyway system with active key control, the standard for landlords managing Rent Ordinance turnover documentation
We source genuine Medeco OEM cylinders, pins, and restricted blanks. Quality aftermarket components are used only where they won’t compromise key control or sidebar tolerance. For San Francisco’s fog-belt corrosion cases, we stock replacement cams and strike hardware that actually holds up to the marine environment - not the standard indoor-grade parts that fail again in eighteen months.
Medeco Service Pricing in San Francisco
Medeco work costs more than standard pin-tumbler service because the parts cost more and the pinning requires specialized equipment. Here’s what we typically see in the San Francisco market:
- Medeco rekey (single cylinder): $145-$220 - includes repinning with OEM pins, new keys, and key-control documentation for restricted systems
- Medeco cylinder rebuild (corrosion or wear repair): $180-$290 - includes new sliders, sidebar components, and cam if needed; we quote after inspection
- Medeco Maxum or M3 cylinder replacement: $240-$380 - OEM cylinder, pinned to your keying, with new keys
- Master key system rekey (multi-unit): $95-$140 per cylinder - varies with hierarchy complexity and access levels
- Service call / trip charge: included in quoted price - no separate dispatch fee added at the door
We give you the full price on the phone before anyone is dispatched. That number matches the invoice. No call-out surcharge, no “parts extra” surprise. If you’ve had a locksmith quote one price and charge another, here’s how we handle that differently: we write it down, we stick to it, and we put the guarantee in writing. Call (682) 281-8985 for an exact quote on your Medeco job - estimates are free.

FAQs - Medeco Locksmith in San Francisco
Only if you have the restricted-key card or are listed as an authorized key holder on file with Medeco’s key control program. Without that documentation, we cannot legally duplicate restricted keys - the cylinder must be repinned or replaced and new keys issued on a fresh restricted card. This comes up constantly with San Francisco Rent Ordinance turnovers where the previous landlord or tenant lost the paperwork. Call (682) 281-8985 and we’ll walk you through what documentation you need - estimates are free.
The marine fog belt delivers salt-laden humidity that corrodes cam mechanisms and strike plates faster than inland climates. Your cylinder may still turn, but the bolt won’t throw because the cam is frozen with corrosion - a failure mode we see in buildings barely a decade old, specific to San Francisco’s western neighborhoods. We can often rebuild the cylinder and replace the corroded hardware with marine-grade components. Call (682) 281-8985 for an inspection quote.
Yes - master keying a Medeco M3 or KeyMark system across multiple access points is routine work for our Residential Locksmith in San Francisco. San Francisco’s two- and three-unit vertical flats are built for this exact hierarchy. We survey the existing hardware, design the keying schedule, and deliver a written scope with flat per-cylinder pricing before any work starts. Note that Victorian mortise bodies often need adjustment or adapter hardware to accept modern Medeco cylinders properly.
The ordinance requires documented evidence that keys were changed between tenants - not a specific brand or method. For Medeco restricted-keyway systems, this means the rekey must be paired with updated key-control records: new keys issued, old keys accounted for or invalidated, and documentation that would hold up in a dispute. We provide written key-change completion records on every ordinance rekey. This service pattern barely exists in non-rent-controlled markets like Daly City or San Mateo.
It depends on the mortise body condition and how badly misaligned the cylinder sits. If the case is sound and we can shim or machine a proper seating, we’ll repin the Medeco cylinder and get you years more service. If the mortise body is cracked, warped, or worn beyond tolerance, replacement is the honest call - and we’ll show you why before you spend anything. We’ve saved plenty of Mission and Haight retrofits that other locksmiths wanted to replace entirely.
