We provide independent Medeco service across Half Moon Bay, 94019: rekeying, repair, key duplication, and replacement for Maxum, M3, and Biaxial lines. The difference here is the salt air. Half Moon Bay’s marine layer doesn’t just rust hardware; it seizes high-security cylinders from the inside, and that’s the problem we solve most often in this town. Call (833) 589-8078 for a free estimate. We’ll quote the full price on the phone before anyone gets in a van.
Why Half Moon Bay Residents Choose Us for Medeco Service
Roland Vásquez, our owner, has spent the better part of three decades working locks, and he learned the craft the old way: at City College of San Francisco’s locksmithing and security systems program, then decades of field work across Bay Area neighborhoods. A seized Medeco cylinder takes the same patience as any stubborn mechanism. We bring that patience to every coastside call.
We work on Medeco hardware daily, not occasionally. When someone in Half Moon Bay loses a restricted key or comes back to a second home with a frozen Maxum deadbolt, we’re the shop already stocked with Medeco pin kits and blanks. We don’t make you wait while parts get ordered from a distributor over the hill. And we’re independent: we service Medeco locks without being a Medeco dealer or authorized representative. That means our recommendations are about what your door needs, not what a partnership agreement tells us to sell. One call covers your car, your home, and your emergency. Medeco work is serious; we treat it that way.

Common Medeco Locksmith Problems We Solve in Half Moon Bay
- Salt-air cylinder seizure on north- and west-facing doors. Half Moon Bay’s prevailing wind off the Pacific carries fine salt mist. It works into the hardened pin stacks and sidebars inside Medeco cylinders, pitting surfaces and stiffening movement. A lock that still turns may not be throwing full sidebar engagement. We free these, assess, and re-lubricate with marine-grade product so they stay smooth.
- Vacation-cottage deadbolts that won’t turn at all. Second homes sit empty for months in neighborhoods near Main Street and all through the 94019 corridor. Owners arrive to find the Maxum deadbolt frozen solid. Usually the cylinder isn’t worn out; it’s dry and corroded. We free it, lubricate it, and if the pins have taken water damage, we re-pin rather than replace.
- Restricted key loss. If you lost the only Medeco key to a rental cottage or family home, you’re not just locked out; you’re facing a key-control decision. We re-pin Medeco cylinders to fresh restricted keys and issue new blanks, so whoever found or kept the old key can’t use it. This matters in a town full of seasonal rentals and property managers.
- Wood-framed door alignment failures. Older coastal cottages in Half Moon Bay have wood-framed jambs that swell and shift with damp. A Medeco deadbolt that drags at the strike plate feels like a lock failure, but the cylinder is fine. We true the strike plate, align the bolt path, and often save the hardware entirely.
- Coastal gate and shed cylinder binding. Exterior Medeco gate cylinders near open shoreline and bluffs collect wind-driven moisture and leaf grit. Keys get stiff, then won’t insert. We clean, re-pin if needed, and advise on weather sealing for Medeco hardware that faces the ocean.
Medeco Service in Half Moon Bay: What Local Conditions Mean for Your Equipment
Half Moon Bay’s isolation on Highway 1 is not a small detail. There is no 24-hour locksmith operating within city limits, so when a Medeco lock fails on a Saturday afternoon or a Sunday night, help usually means a technician driving over the hill from San Mateo or Pacifica. Drive time, distance pricing, and unfamiliarity with the coast’s particular hardware problems all pile up. We stock Medeco pin kits and restricted blanks specifically for the 94019 run. This Highway 1 corridor floods with pumpkin-farm traffic in fall and beach traffic all summer; visitors lock keys in cars at surf spots and the Johnston House grounds; rental cottage guests misplace restricted keys that property managers can’t simply copy at the hardware store. Medeco key control means those keys come through a locksmith who can prove authority to duplicate. We keep that process moving in Half Moon Bay because waiting for a shop over the hill isn’t practical when a deadbolt is frozen or a renter is standing in the fog. A lock is only as strong as the decision behind it.
Medeco Models & Products We Service in Half Moon Bay
We service the Medeco Maxum residential deadbolt, the M3 high-security cylinder, the Biaxial deadbolt, and Maxum Pro / 11-series residential deadbolts. Our parts approach is simple: genuine Medeco cylinders, pin kits, and restricted key blanks only. Aftermarket copies of a high-security keyway defeat the point of owning Medeco. We re-pin and re-lubricate sound cylinders; we don’t sell replacements when the existing lock can be restored. Replacement only gets recommended when the body is pitted through or the sidebar is genuinely worn. That’s the honest line, and it’s the same line we’d give a neighbor.
Medeco Service Pricing in Half Moon Bay
What drives Medeco pricing in Half Moon Bay is parts and condition, not mystery. A standard rekey with new restricted keys usually lands between $120 and $220 per cylinder. Replacing a worn Maxum deadbolt runs $250 to $450 installed. Sticky cylinder service and re-lubrication without re-pinning typically runs $80 to $150. If your Medeco deadbolt is frozen and the door is dragging, alignment work adds time. Half Moon Bay’s damp cottages keep us busy with exactly that combination. We quote the full price on the phone before dispatch, and there’s no call-out surcharge added when we arrive. Call (833) 589-8078 for an exact number. Estimates are free.

FAQs – Medeco Locksmith in Half Moon Bay
No. Rekeying Medeco locks requires the correct pin kits, restricted blanks, and a working knowledge of the cylinder design; it does not require dealer authorization. We’re an independent shop, not a Medeco dealer or authorized representative. We use genuine Medeco parts because that’s what keeps the keyway doing its job. Rekeying is the fastest way to take back control of who holds a key. For rekeying a cottage, a front door, or a full set after a tenant leaves, call (833) 589-8078.
The fog belt and salt-laden marine air in Half Moon Bay work into Medeco’s pin stacks and sidebars, causing pitting and stiff movement. The cylinder may need freeing, a thorough clean, and marine-grade lubrication. The pins themselves may still be fine. We open the cylinder, assess internal wear, and tell you if re-pinning will restore function or if replacement is actually warranted. For a stiff or gritty Medeco lock, call (833) 589-8078 and we’ll tell you what you’re dealing with.
Almost always, yes. The failure is usually corrosion and dryness inside the cylinder, not worn-out hardware. We’ve seen this over and over in Half Moon Bay’s second-home stock. A second-home owner on the older cottage blocks near Main Street called after finding the front-door Medeco Maxum frozen solid; the key wouldn’t turn past the first pin. We freed and re-lubricated the cylinder, found the wood door had swelled enough to drag the bolt at the strike, trued the strike plate, and re-pinned the Maxum to a fresh restricted key set so the property manager could hold one controlled key. If your cottage’s Medeco won’t budge, call (833) 589-8078 before assuming it’s dead.
Yes, in most cases. Half Moon Bay’s Main Street and historic-district doors often have vintage mortise locks that aren’t compatible with modern replaceable cylinders without adaptation. We assess the mortise body, the dimensions of the existing cylinder, and the door thickness. We can install a Medeco M3 or Biaxial cylinder in a working mortise body if the dimensions allow, which upgrades the key control without ripping out the original hardware. For an honest assessment of your historic door, call (833) 589-8078.
You re-pin the cylinder to a fresh restricted key and get new blanks cut from the registration card. The old key is then useless. If there’s no registration card and the keyway is restricted, we verify ownership and request the appropriate key-cutting authorization, which is part of the key-control system Medeco owners pay for. We handle this regularly for Half Moon Bay rental owners and property managers. Call (833) 589-8078 and we’ll walk you through what’s needed.
