We service and rekey Medeco high-security locks across Penngrove, including Maxum and Biaxial deadbolts, rim and mortise cylinders, and restricted-key padlocks on gates and outbuildings. We’re an independent shop, not Medeco-authorized, which means we give you a straight read on whether a cylinder can be rebuilt or needs replacing. What makes our Medeco work here different is that Penngrove’s unincorporated, multi-building parcels often need one restricted key to run four or five separate structures, not just a front door. Call (877) 265-4385 for a free estimate.
Why Penngrove Residents Choose Us for Medeco Service
Medeco cylinders are not something every locksmith sees weekly. We do. Our crew pins and rebuilds Medeco rotating-pin hardware regularly, which means we know when a stiff key is a dirty sidebar and when it’s a worn pin stack that needs a full repin. Noel Carver, our owner and lead locksmith, completed a locksmithing and security systems program at Fresno City College and has been working on high-security cylinders for going on two decades. That experience matters on a Penngrove ranch where the hardware is often decades old and non-standard. We stock Medeco-spec pins, springs, and key blanks locally, so most Penngrove jobs don’t wait on a parts order. And because we work on eight lock brands, we won’t pressure you into replacing a serviceable Medeco lock with something else just because it’s easier for us. Medeco sales & service is a core part of what we do, not an afterthought.

Common Medeco Locksmith Problems We Solve in Penngrove
- Seized gate padlocks after wet winters. Penngrove’s winter rain and seasonal fog push moisture into exposed padlock cylinders on driveway gates and barn doors. The rotating pins and plug corrode just enough that the key turns hard or won’t turn at all. We disassemble, clean, and re-pin the cylinder with Medeco-spec pins, and the padlock goes back into service instead of the scrap bin.
- Maxum deadbolts that turn but won’t throw in summer. Dry summer heat swells ranch-era wood doors and frames across Penngrove. The cylinder works fine, but the bolt is out of strike alignment, so the lock feels broken when it isn’t. We realign the strike and adjust the bolt throw rather than selling you a new deadbolt.
- Lost key-control cards on older Medeco retrofits. Many Penngrove homes from the mid-century era had Medeco cylinders retrofitted into existing mortise or rim locks. The original key card often vanished decades ago. When that’s the case, the restricted keyway can’t be duplicated through normal channels, so we decode the existing key and re-pin the cylinder to a new restricted key.
- Intermittent no-turn on shop and barn cylinders. Grime, leaf dust, and fine Penngrove dust pack into the pin chambers of exterior Medeco cylinders on outbuildings. The sidebar binds, and the key sticks halfway or won’t rotate. A proper disassembly and cleaning fixes what a squirt of lubricant only masks.
- Multiple keyed points scattered across one parcel. A single Penngrove property often has a house deadbolt, a shop rim lock, a barn padlock, and a driveway gate, each on a different key. We build a restricted Medeco master system so one key runs what you want it to run, and a separate key keeps the barn or shop restricted if that’s the intent.
Medeco Service in Penngrove: What Local Conditions Mean for Your Equipment
Penngrove is unincorporated Sonoma County, and a lot of the parcels off Old Redwood Highway and the ranch roads west of Highway 101 run long and wide. A house, a detached shop, a barn, and a driveway gate sit on one deed, sometimes a hundred yards apart. That layout changes what Medeco in Cotati and Penngrove work actually looks like here. In a suburban lot, a Medeco call is usually a front-door rekey. In Penngrove, it’s more often a restricted-key master across four or five separate keyed points, each with its own hardware and its own exposure to the weather. A gate padlock on the east side of a barn takes fog and rain differently than a house deadbolt under a porch eave. When we rekey a Penngrove parcel, we’re not just matching cylinders to keys. We’re thinking about which cylinders sit exposed, which doors swell in summer, and how the key hierarchy should work when a neighbor, a farmhand, or a house sitter needs access to the gate but not the shop. That’s the difference between swapping cylinders and actually solving the access problem.
Medeco Models & Products We Service in Penngrove
We work on the Medeco Maxum deadbolt, the Biaxial deadbolt and rim and mortise cylinders, the original high-security cylinder line, and key-marked restricted-keyway padlocks on gates and outbuildings. Our default is to pin and rebuild genuine Medeco cylinders with Medeco-spec pins and springs whenever the body and sidebar are sound. We only push a full replacement when the shell is cracked, corroded through, or the key control is unrecoverable. For most Penngrove and Medeco repair in Rohnert Park calls, we can complete the work same-day because the common Medeco pin kits and blanks are on the truck, not in a warehouse two states away.
Medeco Service Pricing in Penngrove
| Service | Typical Range |
|---|---|
| Medeco cylinder rebuild (clean, re-pin, new keys) | $85 – $160 per cylinder |
| Rekey a Medeco lock to a new restricted key | $65 – $120 per cylinder |
| Multi-structure master key setup (house, shop, barn, gate) | $250 – $550 depending on cylinder count |
| Medeco padlock rekey or repair | $55 – $110 |
| Service call to Penngrove (no call-out surcharge) | Included in quote; free estimate over the phone |
What drives the cost is cylinder count and condition. A seized padlock that needs a full teardown costs more than a simple rekey. A master-key job across five structures is a bigger job than a single deadbolt. What we can tell you before we dispatch is the exact price, quoted on the phone, and that price is the price on the invoice. No call-out surcharge added on arrival. Call (877) 265-4385 and we’ll give you a firm number.

FAQs – Medeco Locksmith in Penngrove
Yes. A missing key-control card doesn’t make a Medeco cylinder unserviceable. We decode the existing key or pick the cylinder, then re-pin it to a new restricted key and issue fresh key-control paperwork so you’re not locked out of future duplicates. Call (877) 265-4385 if you’ve lost the card and need it sorted.
In Penngrove, dry summer heat swells ranch-era wood doors and frames. The cylinder and bolt are usually fine. The bolt is out of alignment with the strike plate. We correct the strike and adjust the bolt throw, which fixes the problem without replacing the lock.
Yes. That’s a restricted-key master system, and it’s one of the most common requests we get on Medeco repair in Petaluma and Penngrove parcels with multiple outbuildings. One key runs the points you want it to run. A second key can be cut to exclude the barn or shop if you want to keep those off-limits to certain people.
Usually repair. Winter rain and fog in Penngrove corrode the rotating pins and plug inside the padlock body. We disassemble, clean, and re-pin the cylinder with Medeco-spec parts, and the padlock works like it should. Replacement only makes sense if the body is cracked or corroded through, which we’ll tell you honestly. Call (877) 265-4385 and we’ll assess it.
We do. Those retrofits are common in Medeco in Eldridge and Penngrove’s mid-century ranch homes and farmhouses. The Medeco cylinder inside an old mortise or rim lock body can be re-pinned, decoded, and rebuilt as long as the cylinder shell and sidebar are sound. We’ll tell you if the surrounding lock body is the weak point.
