We provide independent Medeco service across San Anselmo and nearby communities, from Medeco repair in Ross to rekeying and cylinder rebuilds to full deadbolt replacement on homes and storefronts. What makes our Medeco work different here is that we understand how San Anselmo Creek’s flood cycle and the town’s older housing stock interact with these precision locks. If your Medeco cylinder has seized or your key stopped turning, call Citadel Locksmith at (833) 589-8078 for a straight answer and a free estimate.
Why San Anselmo Residents Choose Us for Medeco Service
Medeco locks are unforgiving of shortcuts. The sidebar pins, the tight tolerances, the restricted keyways – they reward a technician who has actually torn these cylinders down and rebuilt them, not one who fumbles through a first encounter. Roland Vásquez, who leads our team, learned the mechanical fundamentals of high-security locksmithing at City College of San Francisco and has spent decades working Marin and San Francisco hardware, including a number of Medeco cylinders that other shops wrote off as unserviceable. We stock genuine Medeco OEM pins, springs, and sidebar components. And we know the San Anselmo-specific ways these locks fail. If you’re looking for Medeco sales & service from people who work on the hardware itself, we fit that description without being a Medeco dealer or authorized affiliate. We’re independent, which means our recommendation is based on your lock and your door, not a brand quota.
Our coverage includes all of San Anselmo service area ZIP codes 94960 and 94979, from the flats along Sir Francis Drake Blvd up into the Ross Valley hills. One call covers your car, your home, and your emergency.

Common Medeco Locksmith Problems We Solve in San Anselmo
- Sidebar pins frozen by flood corrosion. Medeco’s precision sidebar tolerates far less grit than a standard pin tumbler. When a wet winter pushes San Anselmo Creek over its banks and the lock takes on water, those fine pins and springs can gum up completely. We pull the cylinder, clean it properly, and re-pin with OEM components.
- Restricted keyway cylinders that seize from old lubrication. Many 1950s bungalows up the Ross Valley hills were fitted with Medeco cylinders by original owners who never re-lubricated them. Years of seasonal door swelling and dry hardened pins eventually bind the plug. The key won’t turn, or it feels rough halfway through.
- Mortise-lock Medeco retrofit cylinders misaligned with warped strike plates. Older San Anselmo homes often have original mortise locks. A Medeco cylinder retrofit into a door that has warped seasonally can leave the bolt hanging on the strike. The key feels stuck, but the cylinder itself is fine, it’s a door movement problem.
- Lost or unregistered restricted keys. Buyers of older San Anselmo homes sometimes inherit a Medeco lock with no key-control card. You cannot simply duplicate those keys at a hardware counter. The cylinder has to be re-pinned or replaced so you actually control who holds a key.
- Deadbolts that won’t throw fully after a wet winter. A swollen door drags the bolt against the frame, and with a Medeco Maxum’s tight tolerances, that drag can feel like a broken lock. We’ve fixed many of these on Sir Francis Drake Blvd homes close to the creek.
Medeco Service in San Anselmo: What Local Conditions Mean for Your Equipment
Downtown San Anselmo genuinely floods when San Anselmo Creek tops its banks. Shops on San Anselmo Ave and homes in the low-lying flats take on water, and the Medeco cylinders on those doors corrode differently than the same locks up in the dry hills. We often find the same-brand lock failing on the flats and working fine up the hill, which changes the repair call entirely. On the flats, we typically see water intrusion into the cylinder plug, rust on the sidebar pins, and swollen wood doors that drag the bolt. Up hill, the failures are more about seasonal swelling from rain exposure and old, dried-out lubricant. The split matters: a corroded, water-damaged cylinder is usually a re-pin or replacement job. A swollen-door alignment problem is a strike plate and hinge adjustment. We diagnose which one you have before touching the hardware. A vignette that stuck with us: a homeowner on Sir Francis Drake Blvd near the creek had a Medeco Maxum deadbolt that had stopped throwing fully after a wet winter. The door had swelled and the sidebar was dragging on a corroded pin. We pulled the cylinder, cleaned and re-pinned it with OEM Medeco components, adjusted the strike plate to the warped jamb, and had the deadbolt turning cleanly again without replacing the hardware. That is the difference between knowing the lock and knowing the town.
Medeco Models & Products We Service in San Anselmo
We service the Medeco Maxum deadbolt series, the M3 and M4 high-security cylinders, the Medeco Original (Biaxial) deadbolt and knob cylinders, and the eCLIQ electronic cylinder. For each, we carry genuine Medeco OEM parts rather than aftermarket substitutes, because a cheap aftermarket pin in a Medeco plug is a security downgrade. When a cylinder is worn past spec, we say so plainly and explain whether a re-pin will hold or whether replacing the cylinder is the smarter long-term call. That honesty matters when you’re securing an older San Anselmo home with non-standard door hardware that cannot simply be swapped for a big-box deadbolt.
Medeco Service Pricing in San Anselmo
The final cost of Medeco service in San Anselmo depends on what the cylinder needs. A standard rekey, including new restricted keys where key control allows, typically runs between $150 and $350 depending on cylinder count and key type. A full Medeco cylinder rebuild with OEM pins and sidebar components is generally in the $180 to $400 range per cylinder. Replacing a Medeco Maxum deadbolt outright, including hardware and installation, falls between $250 and $600. eCLIQ electronic work, when it involves programming or replacing electronic cylinders, generally starts around $300 and goes up from there. What drives the price is parts cost, cylinder condition, and whether the door itself needs alignment work before the lock will function correctly. The price we quote on the phone is the price on the invoice, no dispatch fee tacked on at the door. Call (833) 589-8078 for an exact quote. Estimates are free.

FAQs – Medeco Locksmith in San Anselmo
Yes. Without the key-control card, we cannot simply cut new restricted keys, but we can re-pin the cylinder to a new key set and re-establish control so you are the only party holding working keys. This is common in San Anselmo home purchases where the prior owner left no paperwork. Call (833) 589-8078 and we will walk you through the options.
In San Anselmo and Sleepy Hollow Medeco service calls, the usual answer is water. Low-lying homes and storefronts near San Anselmo Creek take on water during flood season, and Medeco’s sidebar tolerates far less grit than a standard pin tumbler. A swollen door can also drag the bolt. We diagnose which problem you have before repairing anything. Call (833) 589-8078 for an honest assessment.
Yes, in most cases we can retrofit a Medeco cylinder into an existing mortise lock body, provided the lock is structurally sound. If the mortise body is worn, we may recommend a full replacement with period-appropriate hardware that accepts a Medeco cylinder. This is regular work for us in San Anselmo’s older housing stock.
The Maxum is a deadbolt series built around the Medeco high-security sidebar, with strong physical construction. The M3 cylinder offers key control and patended keying flexibility through Medeco’s M3 technology. For most San Anselmo homeowners, either provides serious protection; the choice depends on your door type, existing hardware, and whether you want electronic key control options. We can explain the tradeoffs over the phone.
Yes, regularly. After a wet winter, we get calls from shops along San Anselmo Ave and from Kentfield Medeco service requests whose Medeco cylinders have taken on water and seized. We remove the cylinder, clean and re-pin it with OEM components if the body is still within spec, and adjust the door so the bolt throws cleanly. Call (833) 589-8078 and we will come out the same day if the schedule allows.
