We’re an independent Medeco service provider in Rohnert Park, not a manufacturer affiliate, and we work on the lock you already have. What makes our Medeco work different here is simple: Rohnert Park’s Golis-built tracts left entire streets sharing builder keyways, so a Medeco cylinder in this town is as much about ending shared keys as it is about high-security pins. Call (877) 265-4385 for service across 94926, 94927, and 94928, or visit our Car Key Replacement – Rohnert Park page.
Why Rohnert Park Residents Choose Us for Medeco Service
Medeco locks are not something every locksmith touches. The restricted keyways, the pinning geometry, the key-control cards – it takes hands-on time with the hardware, and that’s time we’ve put in across Sonoma County, including Medeco service in Cotati. Noel Carver, our owner, went through a locksmithing and security systems program at Fresno City College and has been running calls in this part of California for close to two decades. He’s the one who showed us that a Medeco cylinder seized by Rohnert Park winter moisture usually just needs a proper clean and re-pin, not a replacement.
We carry pinning kits and cylinder stock for the Medeco models people actually have on their doors in Rohnert Park – Maxum deadbolts, Biaxial cylinders, Original cylinders, and the M3/M4 high-security keyways. That means we can do restricted-keyway work on the spot instead of sending your lock out. If you’re upgrading from builder-grade hardware, we’ll tell you honestly whether a Medeco is the right call for your door or whether a rekey gets you where you need to be for less. Know your hardware, know your options – the rest is just turning a key.

Common Medeco Locksmith Problems We Solve in Rohnert Park
- Restricted-keyway cylinders seized by winter moisture. Rohnert Park sits in Sonoma County’s fog-influenced valley, and those cool wet winters push corrosion into exterior Medeco pins and springs. By the second or third wet season, the key stops turning smoothly. We clean, re-pin, and re-lubricate the cylinder so it works like it should.
- Deadbolt binding from summer door swell. The hot dry summers here expand wooden entry doors and shift strike plates. A perfectly good Medeco Maxum bolt won’t throw until the strike is reset or the door edge is planed. We see this on single-story tract homes and the denser infill near the Golf Course area alike.
- Mismatched or orphaned cylinders from previous rekeys. In Golis-era tract homes, a prior owner’s rekey often left a Medeco cylinder on one door and an original builder knob lock on another. The whole-house keying is broken. We bring it back to a single working system.
- Lost key-control cards and missing restricted blanks. When the original key card walks off, you can’t just duplicate a key. We rebuild key control on the restricted system – new cylinders where needed, fresh cards, a clean keyway trail. That’s a service, not a sales pitch.
- One Medeco on a street full of builder keyways. It happens more than you’d think: one house gets a Medeco upgrade, and the keyway no longer matches the street pattern. We handle the rekey so the security upgrade doesn’t turn into a front-door headache.
Medeco Service in Rohnert Park: What Local Conditions Mean for Your Equipment
The Golis-built tracts went up in a few short bursts, and that’s the detail that shapes Medeco work in Rohnert Park more than anywhere else we run calls. Entire blocks can still share the same builder keyway – meaning a neighbor’s original key may fit your original lock. When one homeowner upgrades to a Medeco restricted cylinder, neighbors on the same street often follow, and we end up matching keyways across several houses in a single week. It’s not unusual for us to rekey three or four doors on one street off Country Club Drive, each one moving away from the shared builder pattern and onto its own restricted Medeco keyway. That street-level reality is why Rohnert Park service area work for us leans so heavily on rekeying with Medeco rather than full lock replacement.
Medeco Models & Products We Service in Rohnert Park
We service the Medeco lines you’re likely to have or want: the Maxum deadbolt, the Biaxial cylinder in standard and high-security configuration, the original classic Medeco cylinder, and the newer M3 and M4 high-security keyway cylinders. For anything that holds a keyway’s security, we use genuine Medeco cylinders, pins, and restricted blanks. For non-security trim and reinforcement plates, quality aftermarket hardware is fine and keeps the cost down. If a Medeco cylinder can be cleaned, re-pinned, and rebuilt, we rebuild it. Replacement is the answer when the body is cracked or the keyway is so worn it can no longer hold key control. We stock enough locally to turn most Rohnert Park jobs around the same day.
Medeco Service Pricing in Rohnert Park
Service call and labor for a standard Medeco rekey or cylinder rebuild in Rohnert Park typically runs $65 to $120, depending on the cylinder and what’s been done to it before. Adding a new Medeco Maxum deadbolt installation ranges from $85 to $250 in labor, plus the hardware. Restricted keyway rebuilds with new key cards and controlled blanks run $150 to $350, because you’re paying for key control, not just a key. The price you get on the phone is the price on the invoice – no call-out surcharge added when the tech arrives. Call (877) 265-4385 for an exact quote. Estimates are free.

FAQs – Medeco Locksmith in Rohnert Park
Because Golis Associates built entire tracts in short bursts with the same builder hardware, many streets in Rohnert Park still share keyways. A Medeco restricted cylinder ends that, because the keyway is controlled and keys can only be cut with your key card. We rekey the existing lock to a Medeco restricted cylinder and you get a keyway no neighbor’s original key will fit. Call (877) 265-4385 and we’ll walk you through the cost for your specific door.
Usually not. In Rohnert Park, winter moisture corrodes Medeco pins and springs, and summer heat swells the door and shifts the strike plate. Most of the time we clean and re-lubricate the cylinder, reset the strike, and the lock works fine. If the cylinder body is cracked or the keyway is genuinely worn, we’ll tell you and replace it. Call (877) 265-4385 before you assume the lock is dead.
Yes. We rebuild key control by installing a fresh cylinder or re-pinning the existing one to a new restricted keyway, then issuing new keys and a new key card. You end up with a clean keyway trail and no mystery keys floating around. It costs more than a standard rekey because of the control work, but the phone quote covers it. Call (877) 265-4385 and we’ll give you a number before we dispatch.
Sometimes. If the door slab and frame are solid, a Medeco cylinder on a good deadbolt resets security and gives you restricted keys. If the door is thin, swollen, or the frame is split, we’ll say so and suggest fixing the door first. We’d rather talk you out of a Medeco on a door that can’t hold it than sell you hardware that won’t do its job. Call (877) 265-4385 for an honest read.
We do. The newer infill construction near Sonoma State and the Golf Course area often has keyed-alike entry systems and common-area hardware on Medeco or similar restricted cylinders. We service individual units and common-area locks, and we handle rekeys when a tenant turns over, with Petaluma Medeco service available as well. Call (877) 265-4385 and we’ll schedule a time that works.
