Medeco Locksmith in San Francisco, NY | Novak Lock & Security
Novak Lock & Security provides independent Medeco service across San Francisco, from San Francisco Lock Installation & Rekey services like cylinder rebuilds to new Maxum deadbolt installs on Victorian and Edwardian row houses. The one thing that makes our Medeco work here different is that we calibrate our cutters and pin stock to factory Medeco keyways while also knowing which San Francisco buildings will fight a modern cylinder retrofit, because most of them were built before 1920. We are not authorized by Medeco, but we service their locks every week and stock genuine Medeco pins, springs, and key blanks. Call (331) 310-8471 for a written price before anyone is dispatched.
Why San Francisco Residents Choose Us for Medeco Service
We work on Medeco cylinders in San Francisco more than most shops in the Bay Area because the housing stock demands it. A landlord on a pre-1979 Rent Ordinance building needs a dated rekey receipt that will hold up in a tenant dispute. A homeowner in the Outer Sunset needs a Maxum deadbolt that will not seize up after two winters of salt fog. Daniel Novak grew up in Astoria, Queens, two blocks from the elevated N train, and learned the trade at Queensborough Community College before spending two decades working New York City doors, deadbolts, and cylinders. He brought that training to San Francisco, where the locks are older, the tenant turnover is faster, and the fog is harder on brass pins than anything he saw in Queens.
The reason customers stay with us is simple. We name the part, state what we found, and put the price in writing before touching anything. If a Medeco cylinder is pitted past saving, we say so and quote a replacement. If the sidebar is just gummed up, we clean it and charge you for the cleaning, not a new lock. That is Haven Standard Clause 1: the price on the phone is the price on the invoice. We’ve worked under that rule since 2002.
Common Medeco Locksmith Problems We Solve in San Francisco
Every city has its own lock failure patterns. Here is what we actually find in San Francisco, week after week.
- Salt-air seized cylinders in the Sunset and Richmond. The marine layer that sits over the Outer Sunset, Inner Richmond, and Parkside pushes salt-laden air into exposed deadbolts. Medeco cylinders have brass pins and stainless sidebar springs, and after two to three years that combination develops a gritty, stiff keyway that eventually refuses to turn. We clean, re-lubricate, and inspect for pitting that means a full cylinder replacement.
- Off-center Maxum deadbolt retrofits on Victorian doors. Original 2-1/8″ cross-bores were often reamed by hand a century ago, which means they’re rarely square. A Medeco Maxum deadbolt installed in an off-center bore wears its tailpiece and set screws unevenly, and the lock starts jamming intermittently within a couple of years. We see this constantly on Edwardian flats built between 1900 and 1915.
- Broken key tops in pre-1979 apartment locks. Tenants force keys, especially in older Biaxial cylinders that have years of dirt in the keyway. The key top snaps off inside the cylinder, and you cannot just yank it out with pliers. We use extractor tools and then cut a new key on a genuine Medeco blank.
- Mortise prep conflicts on original front doors. A big share of San Francisco’s row houses still have original mortise-lock pockets from the 1880s through 1915. Retrofitting a Medeco cylinder or Maxum deadbolt into that prep is not a drill-and-go job. We are used to edge-mounted thumbturns and narrow door stiles, and we will tell you in advance what will fit and what will not.
- Soft-story retrofit damage to garage door cylinders. San Francisco’s mandatory Soft Story Retrofit Program has replaced thousands of ground-floor garage doors on pre-1978 buildings. When a contractor rehangs a door, the existing Medeco rim or mortise cylinder often gets misaligned, and we get called to repair broken sidebar pins or key pins that now prevent the door from closing securely.
- Rent Ordinance rekey compliance. This is less a lock failure and more a legal one. San Francisco Rent Ordinance rules covering most units built before June 13, 1979 require locks to be rekeyed between tenancies, and the owner needs a dated, itemized receipt. We issue that receipt as standard on every residential rekey, including Medeco cylinders.
Medeco Service in San Francisco: What Local Conditions Mean for Your Equipment
Here is a fact most Medeco pages never mention: in San Francisco, the city’s Rent Ordinance interacts with century-old door prep in a way no other Bay Area city experiences. When a landlord on a pre-June-1979 building rekeys a Medeco cylinder after tenant turnover, they’re not just swapping pins. They’re fulfilling a legal obligation that requires a dated, itemized receipt showing the unit, the cylinder, and the work done. And because a large portion of those buildings still have original Victorian mortise prep in the front door, the rekey often happens inside a narrow, edge-mortised cylinder pocket that was not designed for a modern high-security deadbolt. We handle that intersection daily: we fit Medeco Maxum deadbolts into narrow 2-1/8″ doors with edge-mounted thumbturns, issue the receipt, and document the whole job in a photo record. That combination of mechanical skill and compliance paperwork is something shops in San Jose or Oakland rarely see, because they do not have San Francisco’s stock of rent-controlled, mortise-locked, pre-earthquake wood frames.
The fog makes it worse. West-side zip codes like 94122 and 94121 see sustained humidity that inland neighborhoods never get. A Medeco cylinder that would last fifteen years in Noe Valley might need a rebuild in the Outer Richmond, simply because the pins and sidebar springs are soaking in salt air every night. We do not tell homeowners to buy a new lock when the housing is still sound. We tell them what we found, and we quote both options, in writing.
Medeco Models & Products We Service in San Francisco
We service the full Medeco lineup that San Francisco properties actually carry. That includes the Medeco Maxum deadbolt, the original Biaxial and Biaxial-compatible cylinders, the M3 system in both Biaxial and Classic format, and KeyMark SFIC cylinders in commercial and apartment settings. Our cutters, pins, and key blanks are calibrated to factory Medeco keyways, because the patented keyways and tight tolerances do not accept aftermarket substitutes. We never cut Medeco keys on generic blanks, and we stock genuine Medeco pins, springs, and cylinders locally so a San Francisco rekey does not wait on a parts shipment from the East Coast. When a Medeco cylinder is worth saving, we re-pin or rebuild it. When the sidebar, sleeve, or keyway is worn or corroded beyond reliable operation, we replace the cylinder and explain why the replacement is the cheaper long-term fix. On west-side homes we specifically advise replacement over repair when there is visible salt-water pitting, because a pitted cylinder will fail again no matter how well we clean it.
Medeco Service Pricing in San Francisco
Medeco service in San Francisco costs more than a Kwikset rekey and less than a full-door replacement, and it varies by cylinder type, condition, and whether we are working in a mortise pocket or a standard cross-bore. A Medeco rekey of an existing cylinder typically runs $35 to $55 per cylinder, resetting the lock to new keys on genuine Medeco blanks, with keys included. Replacing a single Medeco Maxum deadbolt with new hardware and installation generally falls between $220 and $380 depending on the door and prep. Rebuilding a seized Medeco cylinder with new pins, springs, and a sidebar, when the housing is sound, lands between $90 and $160 per cylinder. A two-cylinder mortise retrofit on an original Victorian front door is the most variable job, running $350 to $600 depending on the door thickness, the stile width, and whether we need an edge-mounted thumbturn. Those are the real ranges for San Francisco work. The price we quote on the phone is the price on the invoice, and there is no call-out surcharge added on arrival.

FAQs - Medeco Locksmith in San Francisco
Yes. We rekey Medeco cylinders in pre-June-1979 buildings routinely, and every residential rekey includes a dated, itemized receipt showing the address, the unit, the cylinder type, and the work performed, which is what the Rent Ordinance change-of-occupancy rule requires landlords to keep. The receipt is not an afterthought with us; it is part of the job record we leave with you, alongside a photo log of the work, on every visit. Call (331) 310-8471 and we can tell you over the phone whether your cylinder is worth rekeying or needs a rebuild, and what each option will cost in writing.
It is normal for the Outer Sunset, Inner Richmond, and Parkside, yes. The salt-laden marine layer corrodes brass pins and sidebar springs inside the cylinder, and once a Medeco keyway starts feeling gritty, it will not get better on its own. We open the cylinder, clean the pins and sidebar, re-lubricate with the correct product, and assess whether there is pitting. If the housing is still sound, you are done for another couple of years. If we see salt-water pitting, we will recommend full cylinder replacement, because patching a pitted cylinder is wasted money. A phone quote is free at (331) 310-8471.
In most cases, yes. We work with Medeco M3 and KeyMark SFIC systems, and adding a single cylinder to an existing master key hierarchy is a pinning job, not a full system replacement. We need the current master key or the system’s keying schedule, and we will tell you whether your existing cylinders are in good enough condition to accept new pins. If they are worn, we may recommend replacing only the worn cylinders rather than the whole system. Call (331) 310-8471 and we can quote the work after hearing what you are running.
When a soft-story retrofit rehangs a garage door, the existing Medeco rim or mortise cylinder is often shifted out of alignment with the door frame, which binds the tailpiece or shears the sidebar pins. The key will go in, but the plug will not rotate, or it rotates halfway and stops. We see this on Sunset and Richmond soft-story retrofits at a steady clip. We realign the cylinder or replace the damaged pins, and we verify the door closes securely before we leave. For a firm price before dispatch, call (331) 310-8471.
We use genuine Medeco pins, springs, cylinders, and key blanks exclusively on Medeco work. The patented keyways and tight tolerances do not accept aftermarket substitutes, and we will not cut a Medeco key on a generic blank because it will not seat correctly and it will damage the cylinder over time. We stock those parts locally in San Francisco, which is why we can turn around a Medeco rekey same-day in most cases. Call (331) 310-8471 for a written estimate; the price we quote on the phone is the price on the invoice.
