We provide independent Medeco locksmith service across Danville, including the 94506 and 94526 zip codes. The thing that separates our Medeco work here is simple: Danville’s housing stock splits into two very different jobs, and we handle both. Oversized estate doors in the Blackhawk hills rarely accept a standard cylinder prep, so Medeco service in Blackhawk means custom work, while downtown’s century-old bungalows need hand-fitting that no off-the-shelf kit can do. If you’re dealing with a Medeco lock that won’t throw, a restricted key that won’t turn, or a gate call-box that’s failing, call (833) 589-8078.
Why Danville Residents Choose Us for Medeco Service
We work on Medeco cylinders every week, and we’re an independent shop. That matters because we have no quota to sell you a replacement lock when your existing cylinder is mechanically fine. We carry genuine Medeco OEM pins, cams, sidebar springs, and restricted key blanks for Biaxial, Maxum, and M3 systems. If your cylinder is a real Medeco in good shape, we re-pin and re-lubricate it. Replacement only enters the conversation when the body is cracked, pitted through, or the door prep was never right to begin with.
Roland Vásquez, our owner, learned the mechanical side of locksmithing in the City College of San Francisco security systems program and has spent decades working on high-security cylinders that generalist locksmiths won’t touch. That’s the background behind our Medeco sales & service approach in Danville. We stock the common Medeco pin kits and restricted blanks locally so most Danville jobs don’t wait on a parts order. And because we cover Danville service area calls regularly, we already know which neighborhoods have custom-thickness doors and which have vintage mortise bodies.
One more thing: we’ll tell you honestly when the Medeco cylinder isn’t the problem. In Danville, the door or gate hardware around the lock fails more often than the lock itself.

Common Medeco Locksmith Problems We Solve in Danville
- Seized, dry cylinders on sun-exposed doors and gates. Danville’s hot inland summers bake the lubricant out of Medeco cylinders on south- and west-facing entries. The key binds, the pins drag, and the owner assumes the lock is worn out. Most of the time it’s a re-lube and re-pin job, not a replacement.
- Misaligned bolts blamed on the lock. Seasonal swelling and warping on custom-thickness and oversized estate doors means the Medeco bolt no longer throws cleanly into the strike. The cylinder is usually fine. The strike and jamb need re-setting.
- Hardened-steel pins packed with grit. Gate, driveway-entry, and call-box cylinders in Danville’s hillside communities rarely get routine service. Dust and grit work into the sidebar and rotating pins, and the key gets progressively harder to turn until it stops.
- Medeco cylinders that won’t sit right in old mortise bodies. Downtown Danville’s period bungalows and storefronts often have non-standard backsets and vintage mortise locks. A correct Medeco cylinder still needs adapter or faceplate work before it will function.
- Restricted key systems that stopped matching. We see cases where one door was rekeyed to Medeco but the gate or detached garage stayed on the old keyway. The family has two key rings and thinks the locks are failing. They’re not – the keying system was never finished.
Medeco Service in Danville: What Local Conditions Mean for Your Equipment
Danville’s Medeco work splits along a line you can see on a map. In the 94506 hills and Blackhawk enclaves, the doors are oversized and custom-thickness, built from the 1980s through the 2000s, and standard residential lock kits don’t fit. The recurring call there isn’t a house lockout – it’s a gate or call-box failure at the community entrance where the HOA needs Diablo Medeco service that understands shared access and can match the association’s keying system without breaking the gate operator. The same Medeco cylinder job in that environment means working around door prep that was never standardized and hardware that’s baked by direct afternoon sun.
Downtown, the job flips. Century-old bungalows and storefronts have out-of-spec vintage mortise locks and door thicknesses that don’t match modern specs. Putting a Medeco high-security cylinder into that door means hand-fitting, not swapping. A locksmith who only knows how to bore a 2-1/8″ hole and drop in a residential deadbolt will either walk away or force a retrofit that hurts the door. We don’t. Roland learned on San Francisco’s Victorian flats, so a 1920s mortise body in Danville doesn’t intimidate us, and Medeco service in San Ramon draws on the same old-door expertise. A lock is only as strong as the decision behind it, and the decision here is whether to respect the door you’re working on.
Medeco Models & Products We Service in Danville
We service the full Medeco line that shows up in Danville homes and gates: the Maxum residential deadbolt, the older Biaxial cylinders still running on many estate doors, and the M3 and M4 high-security cylinders used on commercial and multipoint entrances. We also handle key-in-knob and key-in-lever Medeco cylinders on estate and gated-community doors.
For parts, we use genuine Medeco OEM pins, cams, sidebar springs, and restricted blanks. Off-brand internals defeat the point of a high-security cylinder, so we don’t use them. Where the door or jamb is the actual weak link, we install quality aftermarket strike and reinforcement hardware. We stock common Medeco pin kits and restricted key blanks for faster Danville turnaround, and when a cylinder can’t be saved, we tell you before any work begins.
Medeco Service Pricing in Danville
Medeco service in Danville typically runs $120 to $290 for a re-pin and re-lubrication on a single cylinder, depending on the model and whether we’re also re-setting the strike. Full replacement of a Maxum deadbolt runs higher, usually $210 to $420 installed, because we’re fitting the lock to the door rather than the other way around. If the job involves an HOA gate call-box or a shared access system, the price depends on how many cylinders and keys are in scope, and we give you a written number before work starts. The phone quote is the invoice price – no dispatch fee, no call-out surcharge added on arrival. Call (833) 589-8078 for a free estimate on your specific lock.

FAQs – Medeco Locksmith in Danville
Yes, when you have the proper authorization. Medeco restricted keys require a card or letter from the system owner before we can cut additional copies. If you’re the registered owner, bring that documentation and we can cut originals or copies from our restricted blanks. If you’re not the owner, we can’t legally duplicate the key. Call (833) 589-8078 and we’ll walk you through what you need.
It’s often both, which is why we look at the whole assembly. The Medeco cylinder in a gate call-box gets packed with dust and grit from Danville’s dry summers, and the hardened-steel pins bind. But the gate operator’s alignment and the strike on the moving gate arm also drift over time. We’ll diagnose which part actually failed before recommending any repair. Call (833) 589-8078 and we’ll send someone who works on both the lock and the operator.
Probably not. Danville estate doors swell and warp with the heat and winter rains, and the bolt starts riding the strike. The Medeco cylinder itself is usually mechanically sound. We re-set the strike and jamb so the bolt seats cleanly, and we’ll tell you if the lock genuinely needs work. Call (833) 589-8078 for an estimate – most of these jobs don’t require a new lock.
Yes, we do that work regularly. The mortise body on those old Danville bungalows has a non-standard backset and often needs adapter or faceplate work before a Medeco cylinder will sit correctly. We hand-fit the cylinder to the existing body rather than cutting the door apart. If the original mortise body is too far gone, we’ll tell you that plainly and show you options that respect the period hardware. Call (833) 589-8078 and describe your door.
Because the gate cylinder was never included in the rekey. This happens constantly in Danville, especially in hillside communities where the gate is served by a different contractor than the house. The fix is straightforward: we re-pin the gate cylinder to your Medeco keyway and cut matching restricted keys, which is standard Moraga Medeco service for hillside communities. That closes the old key access completely. Call (833) 589-8078 for a flat price per lock.
