We provide independent Medeco service in Moraga and across Alamo, CA (94507), working on restricted-keyway cylinders, high-security deadbolts, and estate gate locks. What makes our Medeco work here different is that we’re not a dealer pushing replacements. We’re technicians who diagnose a seized sidebar or a dropped gate hinge and tell you honestly whether the cylinder needs cleaning, re-pinning, or replacing. Call (833) 589-8078 for a phone quote before we dispatch anyone.
Alamo’s large-lot estates, gated driveways, and detached outbuildings mean we’re servicing master-key setups and perimeter hardware more often than single front doors. If you own Medeco hardware on a property with three or four access points, you’re exactly the kind of customer we work with most. Our Medeco sales & service work spans older Biaxial cylinders still in service and current Maxum and M3 lines, and we keep genuine pin kits and key blanks on the truck for same-day turnaround.
Why Alamo Residents Choose Us for Medeco Service
Medeco locks aren’t hardware-store fare. The restricted keyway, the sidebar mechanism, the hardened pins, they all require a locksmith who actually understands how a high-security cylinder fails and how to fix it without compromising it. Roland Vásquez, our owner and master locksmith, has spent decades working restricted-keyway systems, and he still approaches a seized Medeco the same way he learned back at City College of San Francisco: read the wear, find the cause, fix it once.
Alamo homeowners call us because we’re local to the Diablo Valley corridor and we know what these properties demand. A gated estate off Danville Boulevard needs a different approach than a Walnut Creek Medeco service call. We show up with genuine Medeco cylinders, pin stacks, sidebars, and restricted blanks on the truck, so we’re not making you wait while someone drives to a supplier. And since we’re an independent locksmith, not a Medeco-authorized dealer, our repair-versus-replace advice is based on what your lock is actually doing. Not on a quota.

Common Medeco Locksmith Problems We Solve in Alamo
- Gate cylinders that bind on misaligned strikes. Alamo’s large estate gates sit on heavy hinges that shift through dry summers and wet winters. The Medeco cylinder itself is often fine; the bolt simply can’t throw because the gate has sagged and the strike is out of line. We true the strike, re-align the gate, and only re-pin the cylinder if the pin stack actually shows wear.
- Dust- and grit-packed exterior cylinders. Diablo Valley summers are hot and dusty, and that fine grit works its way into the keyway and pin chambers. Come winter, the first rains turn that dust into a paste that stiffens the sidebar. We disassemble, clean, and lubricate the cylinder before it fails completely.
- Corroded brass and steel on exposed gate posts. West- and south-facing posts on Alamo properties take afternoon sun and seasonal rain, and sprinkler overspray keeps moisture against the hardware. We regularly see pitting on brass components and surface corrosion on hardened steel that makes the key drag hard enough to snap if forced.
- Undocumented master-key setups on multi-building estates. Alamo properties frequently have a gate, a detached garage, a pool house, and a main entry, all keyed to Medeco restricted blanks. When the original key-control card is lost and nobody remembers the hierarchy, we rebuild the master-key system from scratch and leave the owner with proper documentation going forward.
- Worn sidebars on older Biaxial cylinders. Biaxial hardware installed in the 1990s is still in service on many Alamo homes. After decades of key cycles, the sidebar legs wear past spec and the cylinder starts feeling loose even with the correct key. At that point, replacement is the honest call, and we carry current Medeco Maxum and M3 hardware to swap in.
Medeco Service in Alamo: What Local Conditions Mean for Your Equipment
Here’s the thing about Alamo’s oak-studded estate lots off the private lanes near the hillside edges: the driveway gate is often a quarter mile from the house, and that gate gets far more use and far more weather exposure than any front-door deadbolt. The hot, dry summers bake the cylinder body while dust works into the keyway. Then winter rains hit, the gate post shifts slightly, and suddenly a key that’s turned freely for eight months starts binding. We’ve seen Medeco cylinders on Alamo driveway gates fail not because the lock was poor quality, but because the gate hinge dropped a fraction of an inch over one dry season and the bolt was never going to line up with the strike again, no matter how good the cylinder was. That’s the work we do here more than anywhere else: diagnosing the access point, not just the lock.
And because these estates usually put the gate, the detached garage, and the house on separate keys, Medeco’s restricted blanks mean a hardware store copy was never an option. The real service call on an Alamo property is building one documented master-key hierarchy across every access point. Not rekeying a single knob. That’s what we mean when we say the gate, not the front door, is what locals actually call about.
Medeco Models & Products We Service in Alamo
We service the Medeco Maxum residential deadbolt, the M3 high-security cylinder, older Biaxial cylinders still in place from installations decades ago, and Saranap Medeco service covers the same high-security padlocks commonly used on gates and outbuildings across Alamo. When parts are needed we use genuine Medeco cylinders, pin stacks, sidebars, and restricted key blanks. Aftermarket parts in a high-security cylinder defeat the entire point of the lock, and we won’t install them. We keep the common Medeco pin kits and key blanks stocked locally so most Alamo service calls are completed same day without a second trip to a distributor.
Medeco Service Pricing in Alamo
Medeco service in Alamo typically runs $95 to $220 for cylinder cleaning and lubrication, $120 to $185 for re-pinning a cylinder to a new restricted key, and $240 to $480 for a new Medeco Maxum deadbolt installed. Master-key setups across a full estate property generally range from $350 to $900 depending on how many access points are involved and whether we’re rebuilding an undocumented hierarchy from scratch. The wildcard on Alamo gates is usually strike or hinge work rather than lock work, so we quote the full job before anyone is dispatched, and that price is what you’ll see on the invoice when the work is done. Call (833) 589-8078 for an exact quote on your hardware. Estimates are free.

FAQs – Medeco Locksmith in Alamo
Can you cut a copy of my Medeco key in Alamo?
Yes, we can cut and program Medeco restricted keys provided you have the key-control documentation that came with the original system, because restricted blanks can’t be duplicated without proof of ownership. If the control card is lost, we can verify ownership through a rekey and issue new documentation so future copies are straightforward. Call (833) 589-8078 and we’ll walk you through exactly what we need to see.
My gate lock opens but the bolt won’t move – is the Medeco cylinder bad?
Usually not. The key turns freely, which means the pin stack and sidebar are engaging correctly, so the problem is almost always mechanical alignment, not the cylinder itself. On Alamo estate gates, sagging hinges and stretched chains throw the strike out of line, and the bolt binds against the strike plate. We true the gate or adjust the strike before touching the cylinder, and we’ll tell you plainly if it’s an alignment issue or real cylinder wear.
Can one Medeco key work my house, detached garage, and driveway gate?
Yes, that’s exactly the kind of master-key hierarchy we build for Alamo properties. Medeco’s restricted keyway allows us to key each access point independently while your key operates all of them, and we’ll leave you with a key-control card documenting the setup. For an estate where the gate and garage are a hundred yards from the house, this is usually the most useful thing we do. Call (833) 589-8078 for a walkthrough of what’s involved.
Why does my Medeco deadbolt stick after the first winter rains?
Alamo summers deposit fine dust in the keyway and pin chambers, and when the first rains arrive that dust becomes a gritty paste that stiffens the sidebar and pins. The fix is a full disassembly, cleaning, and proper lubrication of the cylinder, and we recommend doing it at the end of the dry season before the lock gets bad enough to snap a key.
Do I need to be home for a Medeco rekey on a gated Alamo property?
We need you there to verify ownership and provide access to the gate, detached garage, and any outbuildings being keyed, because restricted systems require confirmation of control before we issue new keys. We’ll schedule a window that works for you, and the whole job usually takes under two hours depending on how many access points are on the property.
