No manufacturer affiliation. Just the tools, the training, and the parts to do the work right.

Why Cotati Residents Choose Us for Medeco Service

Most locksmiths know Medeco as a name. We know it as a system, one with angled keyway cuts, sidebar pins, and restricted key control that demands a different level of attention than a standard Kwikset or Schlage cylinder. Our owner, Roland Vásquez, learned locksmithing the old way at City College of San Francisco, taking apart mechanical cylinders until he understood exactly why a sidebar binds or a pin stack hangs. That mechanical grounding matters in Cotati, where the Medeco locks we’re called out for are frequently twenty, thirty, or forty years old and carrying weather damage no instruction manual covers. We’re also a local operation, not a dispatch service that routes a contractor from 45 minutes away. When you call about a Medeco deadbolt on a west-facing door near La Plaza, you’re talking to someone who knows what a Sonoma County wet winter does to that exact hardware. And we carry OEM Medeco cylinders and springs, only using aftermarket parts for structural pieces like strikes and reinforcement plates where Medeco doesn’t make the component. Independent, yes. Under-equipped, no.

Common Medeco Locksmith Problems We Solve in Cotati

• Sidebar and pin wear on Original and M3 cylinders. The angled keyway cuts and sidebar pins that make Medeco so hard to pick also make it susceptible to a specific failure: after years of use, those pins wear just enough that the key goes in but won’t turn. On original Cotati locksets, this is often the first sign that a cylinder has reached the end of its service life. We re-pin when the body is sound, replace when it isn’t.
• Moisture corrosion on west- and north-facing doors. Cotati’s mild, wet-winter climate isn’t kind to exterior locksets. By spring, we routinely see Medeco deadbolts that have gone stiff, gritty, or completely seized from months of seasonal moisture rolling in off the Sonoma coast. The fix usually involves cleaning the cylinder, replacing corroded springs, and lubricating with a non-gumming lubricant made for high-security locks. Not WD-40. That makes it worse.
• Lost key-control after real estate transactions. Medeco’s restricted keyway means you can’t walk into a hardware store and have a copy cut. When a Cotati house changes hands, the new owner often discovers the previous owner left one key, or a key is floating around somewhere. Rekeying or re-pinning is the only way to take control back. This is the single most common Medeco call we handle in Cotati, and it’s the one we can usually complete same-day.
• Stripped thumbturns and misaligned deadbolt throws. Older ranch homes settle. Door frames shift by a few millimeters. The Medeco cylinder itself survives, but the bolt starts catching on the strike plate, or the thumbturn spins without retracting the bolt. That’s a mechanical failure at the throw assembly, not the cylinder, and it’s a repair we handle without replacing a perfectly good lock.
• Corroded cylinders on aging La Plaza storefronts. Downtown Cotati’s masonry buildings hold moisture differently than wood-framed homes. We see Medeco cylinders on commercial doors where the exterior has oxidized to a dull gray and the key barely seats. Parts availability, not locksmith skill, is what dictates whether we re-pin or replace those. We stock what we can and tell you honestly when a full replacement is cheaper long-term.

Medeco Service in Cotati: What Local Conditions Mean for Your Equipment

Here’s a checkable fact that shapes Medeco work in Cotati more than any other factor: this city’s housing stock is dominated by 1950s through 1970s single-story ranch and tract homes, and a surprising number of them still carry their original mortise and early cylindrical locksets. That’s not true of a neighboring city like Petaluma, which has far more Victorian and pre-war housing mixed into its grid. In Cotati, the Medeco cylinder you call us about is frequently original to the house, which means it was installed when the door was hung and has weathered 40 or 50 years of Sonoma County winters. Parts for these older cylinders, particularly the sidebar springs and pin kits for early Original-series Medeco, aren’t sitting on a shelf at the Cotati hardware store. What this means for you is straightforward: when we show up, the question isn’t usually “can this be repaired,” it’s “can we still get parts for a cylinder this old.” Sometimes we can. Sometimes we can’t, and rekeying to a new Medeco cylinder or replacing the lock entirely is the only realistic fix. Either way, you get that answer in plain language before any work starts. A lock is only as strong as the decision behind it.

Medeco Models & Products We Service in Cotati

We work on the full Medeco range that exists in Cotati’s housing and commercial stock. That’s the Maxum deadbolt, the residential high-security workhorse you’ll find on upgraded ranch homes. The Original and Classic cylinders, the first-generation angled-keyway locks that are still common on older Cotati doors. The M3 and M4 cylinders, with their patented sidebar technology and restricted key control. And the Maxum 11 and comparable key-control deadbolts that show up on downtown storefronts. Our approach to parts is simple: OEM Medeco cylinders, sidebar springs, and key blanks whenever we can source them. When Medeco doesn’t make the component, like a structural reinforcement plate for a splintered door frame, we use quality aftermarket hardware and tell you exactly what we’re fitting and why. We stock Medeco-specific pinning kits and springs locally so common Cotati repair jobs don’t wait on a distributor.

Medeco Service Pricing in Cotati

FAQs – Medeco Locksmith in Cotati

Can you rekey a Medeco lock if I lost the keys and the original card?

Yes. We don’t need the original Medeco key-control card to rekey your cylinder. We decode the existing lock, re-pin it to a fresh key, and issue you new keys on the spot. If the cylinder is too worn or the sidebar is damaged, we’ll recommend replacement and give you the price before doing anything. Call (833) 589-8078 and we’ll walk you through what you’ve got over the phone.

Why does my Medeco key go in but not turn on my west-facing front door?

On a west-facing Cotati door, that’s almost always moisture corrosion inside the cylinder. Sonoma County’s wet winters push water into the keyway, and over time the pins and springs corrode enough that the key seats but the cylinder won’t rotate. We clean, re-pin, and lubricate with the right product, and most cylinders spin again same-day. If corrosion has cracked the cylinder body, replacement is the call.

Can a Cotati hardware store copy my Medeco key?

No. Medeco keys are cut on restricted blanks controlled by the manufacturer, and no big-box or local hardware store has the blanks or the authorization to duplicate them. That’s the point of the system. If you’ve lost keys and don’t have the original card, rekeying is how you take back control. We carry Medeco blanks and cut new keys on-site in Cotati. Call (833) 589-8078 for a quote.

Do you install Medeco high-security cylinders on older 1950s-70s Cotati ranch doors?

We do, and we’d tell you honestly whether your door is a good candidate before quoting. The wood on some of those older ranch doors has dried and splintered around the lock bore, so a high-security cylinder means nothing if the door itself fails. We check the frame, the strike plate, and the throw alignment before recommending a Medeco upgrade. If the door is sound, a Maxum or M3 cylinder turns that old ranch door into a legitimate barrier.

Is Medeco worth it over a standard deadbolt for a La Plaza storefront?

For a La Plaza storefront with inventory, foot traffic, and a door that’s been kicked once already, yes. Medeco’s pick resistance and restricted key control mean ex-employees can’t copy keys at the hardware store, and the sidebar cylinder defeats every common lockpick attack. The tradeoff is cost and the discipline of keeping your key card. For most Cotati business owners, that’s a good trade. Call (833) 589-8078 and we’ll price a commercial Medeco install or rekey against your current setup, no obligation.
