We provide independent Medeco locksmith service across Pacifica, from Linda Mar up through Pedro Point, Rockaway, and Vallemar, and also offer Medeco service in South San Francisco. The thing that makes our Medeco work here different is simple: we know how Pacifica’s salt fog and blowing sand attack these cylinders, and we stock what it takes to fix them without waiting on parts. Call Cypress Lock & Key at (877) 265-4385 for Medeco repair, rekeying, and replacement in Pacifica.
We are not a Medeco authorized dealer or factory affiliate. We’re an independent locksmith shop with deep hands-on experience across the Medeco line: Biaxial, Maxum, M3, and eCLIQ. If your Medeco lock is seizing, binding, or refusing to turn on a coastal door, we diagnose the actual cause and fix it right the first time. Medeco sales & service is something we do daily, not occasionally.
Why Pacifica Residents Choose Us for Medeco Service
Medeco locks are not like a Kwikset or Schlage cylinder you can swap out with whatever is on the truck. The rotating pin tumbler stack, hardened keyway, and sidebar tolerances demand a locksmith who knows the brand inside out. Our techs work on these systems regularly, and we carry Medeco OEM cylinders, keys, and sidebars in stock so a Pacifica job doesn’t stall waiting for a part to ship.
Noel Carver, owner of Cypress Lock & Key, completed a locksmithing and security systems program at Fresno City College and has spent nearly two decades on calls in coastal Northern California. He knows the difference between a Medeco that needs marine-grade lubrication and one whose tumbler stack is pitted beyond saving. That matters when your ocean-facing deadbolt seizes on a damp Pacifica morning and you need someone who won’t just tell you to replace the whole lockset.
We handle Medeco as part of a full spread of lock brands including Schlage, Kwikset, Baldwin, Yale, Sargent, Mul-T-Lock, and Abloy, and we also provide Medeco service in Broadmoor. That matters because most Pacifica homes mix brands between doors, gates, and storage. We service the lock you already have instead of upselling you into hardware you didn’t ask for.

Common Medeco Locksmith Problems We Solve in Pacifica
- Key goes in but won’t turn on an ocean-facing door. We see this constantly in Rockaway and Pedro Point, where salt fog and blowing sand pack into the cylinder. The rotating tumblers gum up, the key can’t lift the pin stack correctly, and the sidebar won’t release. We pull the cylinder, clean it, lubricate with marine-grade product, and re-pin if needed.
- Salt-corroded keyway and sidebar. Marine air in Pacifica pits the hardened keyway and sidebar surfaces over time. A Medeco key that works fine on an inland door will stick or fail on a beach-facing lock because the sidebar doesn’t seat cleanly. We replace pitted sidebars and keyways with genuine Medeco OEM parts when security integrity depends on it.
- Strike plate and finish pitting on older canyon homes. Medeco’s plated brass and steel components corrode faster on coastal door slabs. Many 1940s-1970s Pacifica homes still have original undersized mortise strike plates that work loose and misalign. We install reinforced strikes and weather seals around the Medeco cylinder to stabilize the door.
- Medeco eCLIQ electronic failures in damp conditions. Beach-side condos near Sharp Park and Linda Mar put eCLIQ cylinders through battery drain and moisture ingress at the reader housing. When the seal degrades, the gate faults and the cylinder stops responding. We diagnose whether it’s the battery, the seal, or the cylinder electronics before recommending replacement.
- Rekeying Medeco locks after a tenant or contractor change. Pacifica has a steady stream of rental turnover, especially in the multi-unit buildings near the beach. We rekey Medeco Biaxial and M3 cylinders to fresh keys without replacing the hardware, so landlords and property managers keep high-security locks on the door without eating a full replacement cost.
Medeco Service in Pacifica: What Local Conditions Mean for Your Equipment
Pacifica’s coastal canyons funnel persistent marine fog and blowing sand against doors in ways a flat, inland neighborhood never sees. The ocean-facing side of a door takes a beating that the interior side simply doesn’t. A Medeco Maxum deadbolt on a Pedro Point or Rockaway front door can be seized solid on the salt side within one season while the inland side of the same lock still looks and feels brand new. The grit and salt work their way into the rotating tumbler stack and the sidebar channel, and once that happens, no amount of wiggling the key will make it turn.
We’ve pulled Medeco cylinders from Pacifica doors where the outside face was pitted and gray, but the interior tailpiece and thumbturn were untouched. That asymmetry tells us exactly where the failure started. The fix isn’t just any lubricant or any replacement part. It’s a marine-grade cleaning, a check of the sidebar channel for pitting, and often a re-pin with fresh tumbler pins because the old ones are so scored they bind under tension. We also look at the strike plate and door alignment. Steep canyon driveways and settling foundations in Pacifica homes can shift a door slab by a few millimeters, which is enough to bind even a perfectly serviced Medeco cylinder.
On one steep Pedro Point driveway, we responded to a homeowner whose ocean-side entry door had a Medeco Maxum deadbolt that would accept the key but not rotate. The rotating tumbler stack was grit-packed and the sidebar was corroded from months of salt fog. We pulled the cylinder, cleaned and re-lubricated it with marine-grade product, replaced the pitted strike with a reinforced one, and re-pinned the lock to a fresh key. The lock worked on the salt side without a full swap. That’s the kind of repair that keeps a good Medeco in service instead of in the landfill.
Medeco Models & Products We Service in Pacifica
We service the full Medeco line that Pacifica homeowners and small businesses actually use. That includes the classic Medeco Biaxial with its 5-pin rotating tumbler stack, the Medeco Maxum deadbolt line, the M3 and Original high-security cylinders, and the Medeco eCLIQ electronic key system. Each has its own failure profile in coastal conditions, and we treat them accordingly.
Our parts approach is straightforward. We use genuine Medeco OEM cylinders, keys, and sidebars anywhere security integrity depends on it. Around them, we use quality aftermarket hardware: reinforced strikes, weather seals, and mounting plates. If a Medeco cylinder is only gritty or slightly misaligned, we clean it, lubricate it with marine-grade product, and re-pin it. We recommend full replacement only when the tumbler stack or keyway is genuinely pitted or seized beyond service. We stock what Pacifica calls need most, so most Medeco jobs are same-day.
Medeco Service Pricing in Pacifica
Medeco service in Pacifica typically runs between $95 and $280 depending on what the lock needs. A standard service call with cylinder cleaning, marine-grade lubrication, and inspection usually lands in the $95-$150 range. Rekeying a Medeco Biaxial or M3 cylinder to a fresh key adds key costs and runs $25-$45 per cylinder. Replacing a pitted sidebar or keyway with OEM parts runs higher, often $165-$280 depending on the model. A full Medeco Maxum deadbolt replacement with new hardware and installation typically falls between $220 and $400.
What drives the cost is the condition of the cylinder. A gritty lock that needs cleaning and lubrication is cheap. A lock that’s been grinding for six months and needs a new sidebar, keyway, and re-pin costs more. We quote the full price on the phone before anyone is dispatched, and that’s the price on the invoice. No call-out surcharge added on arrival.

FAQs – Medeco Locksmith in Pacifica
Usually not. The most likely cause is that salt fog and blowing sand have packed into the rotating tumbler stack and the sidebar channel, binding the mechanism. We clean and re-lubricate the cylinder with marine-grade product in most cases, and the lock turns again. If the keyway or sidebar is deeply pitted, we replace those parts with Medeco OEM components. Call (877) 265-4385 and we’ll tell you what we’re likely looking at before we head out.
We can rekey a Medeco Biaxial to a fresh key without replacing the hardware, as long as the cylinder itself is still serviceable. The rotating pin tumbler stack is re-pinnable and the existing keyway can be rekeyed. If the cylinder is pitted or seized beyond service, replacement is the honest recommendation. We’ll tell you which one applies to your lock.
Because the ocean side is where the salt fog, blowing sand, and damp onshore wind do their work. The exterior cylinder face, keyway, and sidebar get hit by everything Pacifica’s coastal air carries, while the interior thumbturn and tailpiece stay clean. The fix is servicing the exterior cylinder specifically: cleaning, marine-grade lubrication, and inspecting the sidebar channel for pitting. This is a pattern we see on ocean-facing doors throughout Pacifica, not a random failure.
Medeco eCLIQ cylinders can work in coastal conditions, but the housing seal and battery compartment need more attention than they do inland. Damp air and salt intrusion cause battery drain and reader faults when the seal degrades. If your eCLIQ is failing intermittently at a Sharp Park or Linda Mar condo, we diagnose whether it’s the battery, the seal, or the cylinder electronics. We’ll give you a straight answer on repair versus replacement. Call (877) 265-4385 for a free estimate.
If your Pacifica canyon home still has its original 1940s-1970s mortise lock, it’s worth having us look at it. The old hardware is often undersized for coastal exposure and can’t hold a modern high-security cylinder properly. A Medeco Maxum deadbolt with a reinforced strike plate gives you better security and better salt-air durability, similar to the Medeco in Colma installations we service. We can tell you whether your door will accept the upgrade without major rework. Call (877) 265-4385 and we’ll walk you through it.
