Need Medeco service in San Rafael? We’re Cypress Lock & Key, an independent locksmith that works on Medeco cylinders, deadbolts, and keyways across all four San Rafael ZIP codes: 94901, 94903, 94912, and 94915. We cut restricted keys on patent-protected blanks, rebuild worn Medeco cylinders with genuine pin kits, and handle everything from a stiff Maxum deadbolt on a Canal-side home to a Biaxial cylinder that predates the current housing stock. Call (877) 265-4385 and you’ll talk to someone who knows the lock you’re describing, not a dispatcher reading a script.
Why San Rafael Residents Choose Us for Medeco Service
Medeco isn’t a lock you figure out on the job. The sidebar pins, the restricted keyways, the patent-protected blanks, they all mean a locksmith either knows the platform or reaches for the wrong parts and makes the problem worse. We service Medeco sales & service across Marin every week, and we carry genuine Medeco pin kits, sidebar springs, and restricted blanks in the van so a San Rafael call doesn’t turn into a two-trip job. Noel Carver, our owner and lead locksmith, cut his teeth on commercial pin-tumbler work before high-security locks became common in residential San Rafael, and he’s been running calls here long enough to know which side of town eats exterior hardware faster. When a Medeco cylinder comes across our bench, we treat it for what it is: a precision lock that deserves precision parts. Know your hardware, know your options, the rest is just turning a key.

Common Medeco Locksmith Problems We Solve in San Rafael
Medeco locks are built for security, not for salt air and winter rain. Here’s what we see most often in San Rafael:
- Salt-corroded deadbolt trim and seized thumbturns: In the Canal and Baypoint neighborhoods, bay moisture and salt-laden air attack exterior Medeco hardware year-round. The thumbturn gets stiff, then the bolt starts binding, and one day the key won’t complete its turn. We clean, re-pin, and swap corroded trim so the cylinder keeps its security rating.
- Worn or gummed sidebar springs and pins: A Medeco that turned smoothly for years suddenly catches halfway, needs jiggling, or only works in one direction. Owners often blame the key. It’s usually decades of accumulated grime in the sidebar mechanism. We re-pin the cylinder with genuine Medeco pins and the lock turns clean again.
- Winter strike misalignment on older wood doors: San Rafael’s wet winters swell wood doors and frames in the Victorians and craftsman bungalows near downtown and Gerstle Park. The Medeco bolt drags on the strike plate, chews the edge of the plate, and eventually stops seating. We realign the strike and adjust the bolt throw so the lock works without fighting the frame.
- Lost or unreturned restricted keys: You can’t copy a Medeco blank at a hardware store, which is the point of restricted keyways. When a tenant, contractor, or ex-partner fails to return a key, the only real fix is rekeying the cylinder. We handle that on-site and issue new restricted keys on the spot.
- Antique mortise cases needing modern Medeco cylinders: Gerstle Park and the older downtown blocks are full of century-old mortise locksets that were never standardized. Adapting a modern Medeco cylinder into an antique mortise body takes patience and a fair amount of bench work. We’ve done it more times than we can count in San Rafael.
Each of these is a known failure mode with a known fix. No guesswork, no generic replacements.
Medeco Service in San Rafael: What Local Conditions Mean for Your Equipment
Here’s a checkable fact that shapes our Medeco work: San Rafael’s canal-side and Baypoint homes sit in low-lying waterfront air where salt and bay moisture attack exterior hardware all year, while Gerstle Park Victorians a mile uphill deal with a completely different set of problems. The same Medeco Maxum deadbolt that seizes up within a few years on a Baypoint canal-front door might run for a decade on a Gerstle Park porch with only light maintenance. On the water side, we’re pulling cylinders apart to clean salt-corroded sidebar components and replacing hardened trim that’s been chewed by the marine layer. Up the hill, we’re more often adapting Medeco cylinders into original mortise cases that were cut for a lock made in 1920, or rebuilding worn pin stacks in Biaxial cylinders that have outlived two renovations. The maintenance interval changes block by block, not just city by city—whether you need Medeco in San Anselmo or here in San Rafael. A Medeco owner on the Canal who services their lock every couple of years will avoid most failures; the same lock on a shaded Victorian might go five years between calls. That’s not a marketing line; it’s what the hardware tells us.
Medeco Models & Products We Service in San Rafael
We work on the full Medeco residential and light-commercial lineup in San Rafael, including the Maxum deadbolt, M3 and M4 cylinders with sidebar locking, the older Original and Biaxial designs still found on commercial storefronts and long-held Victorians, and eCylinder electronic access-control systems. Parts matter on these locks. We use genuine Medeco pin kits, sidebar springs, and restricted key blanks so the cylinder keeps its rated security and your key control stays intact. Where a cylinder body is sound, we rebuild it; we recommend a new Medeco cylinder only when the housing or sidebar is genuinely worn out. And we never, ever substitute a non-Medeco cylinder into a Medeco-protected door without telling you exactly what that does to your key control and security rating.
Medeco Service Pricing in San Rafael
What you’ll pay for Medeco service in San Rafael depends on what’s actually wrong. A standard service call that covers diagnosis and a simple repair, like a thumbturn adjustment or strike realignment, runs between $89 and $149. Rekeying a Medeco cylinder with new restricted keys typically lands between $25 and $45 per cylinder, plus the keys themselves. A replacement Maxum deadbolt installed runs from $220 to $360. Salt-corrosion repair, which often means stripping the cylinder, cleaning the sidebar, and replacing trim, falls between $120 and $185. And if you need a new Medeco cylinder adapted into an antique mortise case, budget for $190 to $290 depending on how much of the original hardware is salvageable. Every job gets a full quote on the phone before we dispatch, and that’s the price on the invoice. No call-out surcharge added when we arrive. Call (877) 265-4385 for an exact number, estimates are free.

FAQs – Medeco Locksmith in San Rafael
We cut Medeco restricted keys in San Rafael on the correct patent-protected blanks, no dealer authorization required. Medeco’s key control system means the blanks aren’t sold through hardware stores, but a qualified locksmith with the right partnerships can cut and program keys on-site. You don’t have to ship your lock back to Medeco or wait on a factory key. If you’ve lost all your keys, we can cut from the cylinder itself. Call (877) 265-4385 and tell us which Medeco model you have, and we’ll let you know before you commit to anything.
On the Canal and in Baypoint, the most common culprit is salt corrosion from bay moisture working into the sidebar mechanism and exterior trim. The humidity carries salt, salt attracts moisture, and the internal pins and springs gum up until the key starts catching. Sometimes it’s the key cut, but more often it’s the internals. We strip, clean, and re-pin the cylinder with genuine Medeco pins, and the lock usually turns clean again. Call (877) 265-4385 and we’ll give you a straight read before anyone comes out.
Probably not the lock. San Rafael’s wet winters swell wood doors and frames in older Victorians and bungalows, and the swelling shifts the strike plate just enough that the bolt drags. The lock’s fine; the door’s moving. We realign the strike and, where needed, deepen the receiver so the bolt seats without chewing the plate. If the cylinder’s also worn, we’ll tell you, but the winter-only stiffness is almost always the wood, not the Medeco.
Yes, and it’s usually the smart move. Losing a restricted Medeco key means someone might have access, so the cylinder should be re-pinned and new restricted keys issued. We do that in San Rafael using genuine Medeco pin kits, not aftermarket substitutions. The shell, the sidebar, and the housing all stay; only the pin stack changes, so the old key won’t turn. It’s faster and less expensive than replacing the whole lock, and it preserves your key control. Call (877) 265-4385 for a per-cylinder quote.
We do. A lot of the newer condo and multi-family buildings in Terra Linda and Northgate went in with builder-grade deadbolts that just aren’t intended for long-term security. Replacing or retrofitting those with a Medeco Maxum or an M3 cylinder gives you a restricted keyway, sidebar locking, and hardware that stands up to San Rafael’s climate, just as we do with Medeco repair in Fairfax. We’ll survey what’s there, recommend the right Medeco product for the door and the exposure, and give you a flat per-lock price before any work starts.
