We provide Medeco sales & service across Fremont, from a $150 re-pin to a full restricted-keyway retrofit. The thing that sets our Medeco work apart here is simple: Fremont’s housing stock splits cleanly between 1950s-70s tract homes that need door prep before a high-security cylinder will even seat, and Mission San Jose estates where Medeco restricted systems are already installed and need re-carding, not retrofitting. Most locksmiths treat those as the same job. They are not.
Roland Vásquez and our team at Citadel Locksmith work on Medeco Maxum, M3, Biaxial, and Classic cylinders every week. We are an independent Medeco service provider, not a factory-authorized dealer, and we carry OEM pins, cams, cylinders, and restricted key blanks so the key control actually holds. Call (833) 589-8078 for a free estimate. Your exact price is quoted on the phone before anyone is dispatched, and that is the price on the invoice.
Why Fremont Residents Choose Us for Medeco Service
Medeco is not a brand you trust to a generalist. The rotating-pin-and-sidebar design on the M3 and the Biaxial pin stack are specific pieces of engineering, and a technician who has never opened one will either drill it unnecessarily or pin it wrong. We open, re-pin, and re-key them regularly. Not all locksmiths speak Medeco or Abloy. We do.
Fremont’s mix of housing also means we arrive prepared for two very different scenarios on any given day. A 1961 ranch in 94538 with an original hollow-metal entry set might need strike realignment and a wrap plate before a Maxum deadbolt will throw clean. A 1970s estate gate off Mission Boulevard in 94539 might just need a re-pin and fresh restricted keys. Roland learned the mechanical side of this trade at City College of San Francisco and has spent three decades working locks in the Bay Area, including plenty of Fremont doors that other shops gave up on. A lock is only as strong as the decision behind it.

Common Medeco Locksmith Problems We Solve in Fremont
Here is what we actually see on Fremont doors, tied to how this city is built and how its weather behaves:
- Stiff or seized cylinders on east- and west-facing doors. Fremont’s dry East Bay summers push UV and fine dust into exposed exterior cylinders. Rotating pins lose lubrication and start to grab. Most people assume the cylinder is failing. Usually it is a dry, dusty pin stack that needs cleaning and re-lubing, not replacement.
- Intermittent bolt throw on retrofitted estate hardware. Grandfathered brass entry sets on 1960s-70s Mission San Jose homes often use mortise bodies that were never designed for a Medeco cylinder. The cam or faceplate fit ends up slightly off, and the bolt sticks partway. We true the strike and cam fit without touching the visible door face.
- Seized tumblers on gate and side-yard locks. Winter storms here are mild by any standard, but the moisture they push into poorly sealed gate cylinders on large Mission San Jose and Palomeras lots is enough to seize tumblers. Gate cylinders sit exposed all year. A re-key plus a proper weather seal fixes it.
- Binding at the strike on 1950s-70s tract homes. Decades of settling leave original single-cylinder deadbolt prep out of square. A Medeco cylinder installed without strike realignment will bind at the plate every time. We re-bore, true the strike, and seat it square.
- Worn keys from regular use in tech-corridor households. Fremont commuters run keys in and out of doors, gates, and mailboxes constantly. Medeco keys hold up well, but worn key shoulders and dulled cuts cause ignition-like resistance in the cylinder. We cut fresh OEM-restricted blanks and re-pin if needed.
Medeco Service in Fremont: What Local Conditions Mean for Your Equipment
Fremont’s ZIPs split the Medeco market down the middle. In 94536 and 94538, most homes are 1940s-70s tract or ranch builds with builder-grade entry sets. Those doors were prepped for a basic single-cylinder deadbolt, and a Medeco Maxum will not seat square into them without re-boring, a wrap plate, and strike work. That is the retrofit side of our Medeco work. In 94539 and 94555, the story flips entirely. Mission San Jose estates and newer Warm Springs tech-worker housing often already have Medeco restricted-keyway or master-key systems installed. Those jobs are about re-pinning, re-carding, and key control, not carpentry. If you live in Fremont and want Medeco, the first question is which kind of job your ZIP actually needs. We quote both accurately because we do both weekly.
Medeco Models & Products We Service in Fremont
We service the Medeco Maxum deadbolt, the M3 high-security cylinder, Biaxial cylinders, and the original Classic rotating-pin deadbolt. For every one of those, we use OEM Medeco pins, cams, cylinders, and restricted key blanks. That matters. A high-security pinning scheme only holds if the parts are genuine. We use quality aftermarket hardware only where it does not touch the Medeco cylinder itself: strikes, reinforcement plates, and door prep. We repair and re-pin a sound Medeco cylinder whenever the body and sidebar are intact. Replacement is the last option, not the first pitch. For Fremont turnaround, we stock common Medeco pin kits, key blanks, cams, and tailpieces locally, so most re-pins and re-keys happen same visit.
Medeco Service Pricing in Fremont
Here is what Medeco work typically costs in Fremont. Your exact price gets quoted on the phone before we dispatch, and that is the number on your invoice:
- Medeco re-key or re-pin (standard cylinder): $85 to $160 per cylinder
- Restricted keyway re-key with new OEM key blanks: $120 to $220
- Medeco Maxum deadbolt installation (with door prep): $240 to $450 depending on wrap plate and strike work
- Existing Medeco cylinder repair or cleanup (no parts): $75 to $130
- Gate or side-yard Medeco cylinder replacement: $190 to $350 including weather seal
What drives the cost is door prep, strike condition, and whether you need restricted keys cut from a card or code. There is no call-out surcharge added on arrival. The quote you get on the phone is the price you pay.

FAQs – Medeco Locksmith in Fremont
Can you re-key a Medeco lock in Fremont without the original key or key card? Yes. We can re-key most Medeco cylinders without the original key or card by decoding the existing pins or replacing the pin stack and sidebar as needed. If the cylinder is not damaged, we re-pin it and cut fresh OEM restricted keys on site. Call (833) 589-8078 and we will tell you exactly what your lock needs.
My 1960s tract home in 94538 has a builder deadbolt – can a Medeco Maxum go straight in? Usually not without prep. Original tract-home doors settled over decades, and the deadbolt prep is often out of square for a modern high-security cylinder. We re-bore, add a wrap plate where the thin door edge needs it, and true the strike so the Maxum throws clean. It is a standard retrofit for us in Fremont.
Why does my Medeco deadbolt feel stiff on an east-facing door in summer? Fremont’s dry summer heat bakes the sun-facing side of your door. Dust works into the cylinder, the factory lubrication evaporates, and the rotating pins begin to grab. It feels like a failing lock, but in most cases it is a dry pin stack. We clean, lubricate, and re-pin only if needed. A quick phone quote will confirm: (833) 589-8078.
Do you install Medeco high-security hardware on Mission San Jose estate gates and side-yard doors? Yes. Large Mission San Jose and Palomeras lots put gate and side-yard cylinders out in the weather, and those are the locks that seize after winter moisture. We provide Union City Medeco service nearby and install Medeco gate cylinders with proper weather sealing and re-pin existing hardware while retaining the estate door’s original brass face. That visible-face preservation is a big part of the work we do in 94539.
Are you authorized by Medeco? No. We are an independent Medeco service provider. We service Medeco cylinders with genuine OEM parts and restricted key blanks because we know the architecture, not because we carry a factory authorization. If you need repair, re-pinning, or retrofit, we can help. Call (833) 589-8078 for a free estimate.
