We provide independent Medeco locksmith service across Vallejo, including rekeying, repair, master key systems, and retrofit work on everything from a 1950s flatlands deadbolt to an 1890s Mare Island mortise lock. Medeco high-security hardware is mechanically different from standard locks, and the one thing that sets our Medeco work here apart is that we understand how Vallejo’s salty marine air and historic housing stock interact with Medeco’s tight-tolerance cylinders. If your Medeco lock is sticking, seizing, or you need keys made on a restricted keyway, call Cypress Lock & Key at (877) 265-4385 and tell us what you’ve got. We’ll walk you through it.
Why Vallejo Residents Choose Us for Medeco Service
Most Bay Area locksmiths see a Medeco cylinder and either turn the job down or quote you a full replacement you don’t need. We’ve serviced Medeco locks across Vallejo for years, so the name and the mechanics don’t scare us. Noel Carver, our owner and lead locksmith, completed a locksmithing and security systems program at Fresno City College that covered high-security pinning systems, and he’s been running calls in this part of Northern California for nearly two decades. That means when you call with a seized Medeco Maxum deadbolt on a west-facing door in 94591, we already know what to expect before we pull up. We stock Medeco sales & service parts, including OEM pins, springs, and cylinders, so most jobs don’t wait on a parts order. And we’re local to Vallejo, which means same-day service on most Medeco repairs.

Common Medeco Locksmith Problems We Solve in Vallejo
Medeco locks are built to tighter tolerances than anything you’ll find at a big-box store. That’s what makes them secure. It’s also what makes them less forgiving when Vallejo’s conditions get involved. Here’s what we see most often:
- Cylinder seizure from Carquinez Strait salt air. West-facing doors in 94590 and 94591 catch damp marine air that works into Medeco cylinders and corrodes the pins. The tight clearances that make Medeco hard to pick also make them quick to seize once corrosion starts. We disassemble, clean, and re-pin rather than replace when the cylinder body is still sound.
- Pin and spring degradation from condensation. Vallejo’s morning marine layer and winter humidity condense inside locks, especially on exterior doors that go from cold nights to warmer mornings. Medeco pins and springs are precise little machines; condensation plus no lubrication means keys stick, cylinders fail to rotate fully, and eventually the whole mechanism binds. This is a repair we do constantly here.
- Worn or bent restricted keys that break off. Medeco’s restricted keyways are tighter than standard keyways, so a worn or slightly bent key binds and snaps, often inside an older Maxum or Biaxial deadbolt. We extract broken keys and cut fresh ones from the key code when the owner has it on file, or re-key the cylinder if the code’s been lost.
- Smart lock integration failures on Medeco mechanical cylinders. Some Vallejo homeowners and landlords pair a Medeco mechanical cylinder with an aftermarket smart lock for remote access. The deadbolt alignment shifts, the motor can’t drive the tighter Medeco mechanism, and the lock binds. We fix the integration or tell you honestly if the pairing won’t work long-term.
- Historic mortise locks that won’t accept modern Medeco blanks. On Mare Island’s officers’ quarters, the original 19th-century mortise cases don’t fit standard Medeco mortise bodies, and the door prep is too shallow for a Maxum deadbolt without major modification. We machine cylinders and fabricate keys to match the historic hardware. More on that below.
Medeco Service in Vallejo: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Medeco service page: Vallejo is one of the few Bay Area cities where a Medeco technician regularly works on locks in buildings that predate the Civil War. Mare Island’s historic officers’ quarters, built from the 1850s through the 1940s, still contain original brass mortise locks with bit-key mechanisms and skeleton-key hardware. When those buildings get Medeco high-security retrofits, the job isn’t a simple cylinder swap. The original mortise case won’t accept a modern Medeco mortise body and the door prep is sized for 19th-century hardware, not a Maxum. We have to machine a cylinder to fit the existing case and hand-fabricate a key that turns smoothly in a door that’s been swinging for over a century. Noel’s grandfather was a machinist who believed every man should understand how mechanical things worked, and that thinking carries through to this work more than any other. A generic locksmith in a neighboring city might see one of these locks once a year. We see them regularly.
Medeco Models & Products We Service in Vallejo
We work on the full Medeco line you’re likely to have in Vallejo: the Medeco Maxum deadbolt, Medeco M3 and M4 cylinders, Medeco Biaxial cylinders, and the classic Medeco Original locks still found in older commercial settings. Our first choice is always genuine Medeco OEM pins, springs, and cylinders, sourced directly through our supply chain. For obsolete or discontinued lines where Medeco no longer manufactures the part, we turn to quality aftermarket components and machine work to keep the lock serviceable. We stock common Medeco pins and key blanks locally for fast Vallejo turnaround. For owners who need restricted keyway access, we re-pin the cylinder to a new keyway we control and issue keys only to authorized parties, which is exactly what a restricted system is for.
Medeco Service Pricing in Vallejo
Medeco service in Vallejo typically runs $85 to $160 for a basic rekey, $95 to $175 for cylinder repair or re-pinning, and $175 to $285 when we’re machining a cylinder or fabricating a key for an unusual application like a Mare Island historic mortise lock. What drives the cost is whether the cylinder can be saved or needs replacement, whether we’re working from an existing key or missing the key code entirely, and how much corrosion has accumulated. A free estimate includes us identifying your Medeco model, checking the cylinder condition, and quoting the full repair or rekey price before any work starts. Call (877) 265-4385 and describe the lock; we’ll tell you what we’d expect to charge and how long it’ll take.

FAQs – Medeco Locksmith in Vallejo
Yes. We re-pin the Medeco cylinder in place or, when the cylinder itself is beyond saving, machine a new one to fit the original mortise case. The historic door, escutcheon, and mortise body stay untouched. This is the entire point of our Mare Island work – modern key control without tearing out hardware that’s been on the building since the 1900s.
It’s the combination of the Carquinez Strait’s salty marine layer and Medeco’s tight mechanical tolerances. West-facing exterior doors in 94590 and 94591 catch damp, salt-laden air that penetrates the cylinder and corrodes the pins. Standard locks have looser clearances and can shrug off some of that; Medeo cylinders bind. It’s not a defect in your lock. It’s the local environment, and it’s serviceable with cleaning and re-pinning. Call (877) 265-4385 if your key’s getting harder to turn.
We keep common pins, springs, and key blanks for Medeco Biaxial and Original lines in our Vallejo service stock. For parts Medeco has discontinued, we source quality aftermarket equivalents and machine anything unusual we can’t order. If you have an older Medeco lock, tell us the model over the phone and we’ll confirm what we have before we roll to you.
Yes. Vallejo’s rental turnover keeps us busy with exactly this: a landlord rekeys every unit between tenants and keeps one master key that opens all of them. We design and pin Medeco master key systems for duplexes, fourplexes, and small apartment buildings across 94589, 94590, 94591, and 94592, plus we offer Crockett Medeco service. It’s cheaper than it sounds, and it’s the right rekey move for a property owner who doesn’t want to carry eight keys. Call (877) 265-4385 for a free estimate on the system size you need.
Don’t try to fish it out with pliers or tweezers – the restricted keyway is tight and you’ll push the broken piece further in. Leave the key in, don’t force the cylinder, and call us. We extract broken Medeco keys from Maxum, Biaxial, and M-series cylinders all over Vallejo, then cut a new key or rekey the cylinder on the spot. Call (877) 265-4385 and we’ll get to you same day.
