We provide independent Car Key Replacement in Fairfax alongside Medeco service, and the work here looks different than in flat-lot towns. The hillside lanes off Bolinas Road shift through damp winters, so a Medeco deadbolt that won’t throw is often a door alignment problem, not a cylinder failure. Noel Carver and our team service Medeco Maxum, M3, and Original Biaxial hardware throughout 94930 and 94978. If your Medeco key turns stiff, won’t copy at the hardware store, or the bolt won’t seat after the rains, call (877) 265-4385.
Why Fairfax Residents Choose Us for Medeco Service
Most locksmiths in Marin can drill out a Medeco and sell you a Kwikset. We’d rather not. We’ve spent years servicing Medeco sales & service on Fairfax’s older homes, so we understand how the hardened pins, sidebar mechanisms, and restricted keyways actually behave in damp, redwood-shaded conditions. We stock Genuine Medeco cylinders, key blanks, and restricted blanks for fast turnaround, and we’re upfront that Cypress Lock & Key is an independent shop, not authorized or endorsed by Medeco. What that means for you: factory parts where they matter, honest guidance where they don’t, and no upsell pressure disguised as security advice.
Noel Carver grew up in a small Central Valley community where nobody thought much about locks until something went wrong. After completing a locksmithing and security systems program at Fresno City College, he spent two decades running calls on mechanical and automotive lock work. The thing Fairfax customers mention most is that he shows up calm. No drama, no pitch, just a clear read of the problem and a clean fix.
We service the full Fairfax service area, from the flats near downtown up into the hillside lanes where the door frames move with the soil.

Common Medeco Locksmith Problems We Solve in Fairfax
- Stiff, dragging Medeco cylinders on shaded north-facing entries. Fairfax’s marine-influenced winters soak lock cylinders on the shaded side of the house. Medeco’s hardened pins and springs don’t rust through, but they do pick up grime and moisture-frost that makes the key turn hard. The lock isn’t broken. It needs freeing, relubing, and sometimes a pin refresh. We rebuild in place whenever the cylinder is sound.
- Deadbolts that won’t throw after the rainy season. On hillside lanes off Bolinas Road and Cascade Drive, the soil swells and shifts all winter. Door jambs move with the ground. Your Medeco Maxum or M3 deadbolt will not seat fully, even though the cylinder tests fine. We realign strikes, shim jambs, and reinforce the frame rather than sell you a replacement lock that would fail the same way.
- Restricted keys cut wrong at big-box stores. Original Biaxial and M3 restricted keyways are designed to be hard to duplicate. That’s the point. When a hardware store key machine cuts a Medeco onto the wrong blank, the key either won’t enter the cylinder or turns halfway and binds. Before you replace a Medeco cylinder over a bad key, let us cut a genuine one and test the lock. It’s usually the key, not the cylinder.
- Lost Medeco keys on a restricted system. If you lose the only key to a Medeco restricted keyway, the fix is not universal. We verify card ownership where applicable, cut from code or decode the cylinder, and get you back in without destroying a several-hundred-dollar deadbolt. Fairfax homeowners with vintage mortise locks paired to Medeco cylinders call us for this exact scenario.
- Vintage wood-frame doors that fight a modern high-security deadbolt. Fairfax’s 1920s-1950s bungalows and hillside cabins often have non-standard door thicknesses, glass-panel doors, or original mortise locks that don’t mount a modern Medeco cleanly. We rebuild period-correct hardware in place and pair it with Medeco where it makes sense, rather than hacking a door apart for a cylinder it wasn’t built to hold.
Medeco Service in Fairfax: What Local Conditions Mean for Your Equipment
Here’s the pattern we see on the hillside lanes off Bolinas Road that flat-lot towns don’t generate. Fairfax sits on soil that swells and shifts through damp winters, and the wooden door frames on those hillside homes move with it. The classic call goes like this: the rains end, the sun comes back, and a homeowner’s key turns fine, but the deadbolt won’t seat. They assume the Medeco cylinder failed. In most cases it hasn’t. The jamb has shifted, the strike plate is out of line with the bolt throw by an eighth of an inch, and a genuinely fine high-security lock gets blamed for a carpentry problem. We realign the strike, reinforce the jamb where needed, and the Medeco works as designed. Knowing the difference saves Fairfax residents from replacing a $200-plus cylinder when the door was the issue all along, and it’s why homeowners needing Medeco service in San Anselmo face similar hillside challenges. Know your hardware, know your options – the rest is just turning a key.
A homeowner on a Bolinas Road hillside lane called us because her Medeco Maxum deadbolt wouldn’t throw after the wet season, and her key felt stiff in the cylinder. Our tech found the cylinder sound but grimy. We freed and relubed the pins, then realigned the strike and reinforced the jamb so the bolt seated fully. Rebuilding in place kept her genuine Medeco hardware and solved the seasonal latch problem without a replacement lock.
Medeco Models & Products We Service in Fairfax
We work on the Medeco hardware you already have and the models you’re considering, including Ross Medeco service referrals when you’re outside our range. That covers the Medeco Maxum deadbolt, the M3 and M3+ high-security cylinders, the Original Biaxial deadbolt, and the Maxum Smart deadbolt. On any of these, we fit Genuine Medeco cylinders, keys, and restricted blanks when you want factory parts. For jamb reinforcement and vintage-door fittings where a Medeco swap isn’t warranted, we use quality aftermarket hardware suited to the existing door, not whatever is on the truck. Our honest stance: if the cylinder is sound, we rebuild and relube it. We tell you plainly when a swollen door or shifted strike, not the Medeco itself, is the real problem. That’s the difference between a parts counter and an actual locksmith.
Medeco Service Pricing in Fairfax
Medeco work in Fairfax runs from roughly $95 to $160 an hour for labor, with cylinder work, rekeying, and restricted key cutting adding parts cost depending on model and card status. A service call generally falls between $75 and $165 depending on where in 94930 or 94978 you are. A straightforward rekey into a Medeco cylinder typically runs $20 to $35 per cylinder labor plus hardware. Full hardware replacement with a new Medeco cylinder can range from $150 to $450 or more, depending on finish and finish. What drives cost: whether the cylinder needs rebuild or replacement, whether keys must be cut from code, and whether the Fairfax hillside has pulled your strike out of alignment. We quote the full price on the phone before anyone is dispatched, and that’s the price on the invoice. No call-out surcharge added on arrival. Call (877) 265-4385 for an exact number, estimates are free.

FAQs – Medeco Locksmith in Fairfax
Sometimes yes, sometimes no, and we’ll tell you which before touching the door. A surface-mounted Medeco Maxum deadbolt can often be added above an existing mortise lock without destroying the original hardware. Medeco also makes mortise cylinders that drop into many vintage mortise cases. Where the door is too thin, warped, or has a glass panel that complicates mounting, we rebuild the period-correct hardware in place rather than force a modern deadbolt into a door that can’t hold it. The answer depends on your specific door thickness, existing mortise body, and frame condition. Call (877) 265-4385 and we’ll give you a straight read.
Usually not. What you’re describing in Fairfax is most often moisture and grime in the cylinder, not failed pins. Shaded north-facing entries on Cascade Drive and similar lanes catch marine damp all winter, and Medeco’s hardened pins and springs can stiffen even though they haven’t rusted. A proper disassembly, cleaning, and Medeco-specified lubrication usually solves it. If the cylinder has also been run with a mis-cut key, the pins may need replacement. We rebuild and relube before we ever recommend a replacement cylinder. Call (877) 265-4385 and describe what you’re feeling at the keyway, we’ll tell you what’s likely.
Yes, where card authorization or proof of ownership allows. Medeco restricted keyways exist precisely so keys can’t be cut casually. We cut genuine Medeco blanks on proper equipment, not the aftermarket clones you’ll find in a big-box key machine. If you have an Original Biaxial or M3 restricted key, bring or send what documentation you have, and we’ll verify and cut. A key that turns halfway and binds is often a hardware-store miscut, not your lock. Call (877) 265-4385 before you replace a cylinder over a bad key.
Yes, and this is exactly the kind of Fairfax call we expect on older bungalows and hillside cabins. Big-box chains are set up to drill and swap, not to rebuild original mortise bodies, source period hardware, or cut restricted keys. We service the lock you already have. Where a Medeco mortise cylinder fits your existing case, we pair it with original hardware. Where the mortise body itself needs work, we rebuild it in place. Sometimes a supplementary Medeco Maxum deadbolt above the mortise is the right call. But “can’t be serviced” usually means “not worth it to us.” Call (877) 265-4385 and we’ll give you a real assessment.
No, it means your strike and jamb probably need realignment. The soil movement under hillside Fairfax lanes shifts door frames through the wet season, and a Medeco deadbolt that won’t throw fully is almost always a frame alignment problem, not a cylinder failure. We check the cylinder, then check the strike, then check the jamb. Often the fix is realigning hardware and reinforcing the frame, not buying a new lock. Call (877) 265-4385 and we’ll tell you which one it is.
