Medeco Locksmith in Fremont, CA | Preston Locksmith & Security
We provide independent Medeco locksmith service across Fremont, California – rekeys, repairs, rebuilds, and replacement cylinders for Medeco Maxum, Biaxial, M3, and Original lines. We’re not authorized or endorsed by Medeco, and we’ll tell you that straight. What we are is a shop that cuts, pins, and rebuilds these cylinders every week, and we know exactly how Fremont’s fog, temperature swings, and 1960s – 70s housing stock affect them. If your Medeco key has started sticking or your cylinder won’t turn cleanly, call (409) 405-4485 and we’ll give you a written price before anyone leaves the shop.
Why Fremont Residents Choose Us for Medeco Service
Medeco locks are not like the hardware-store deadbolts most locksmiths cut their teeth on. They carry restricted keyways with angled cuts, hardened inserts, and sidebar mechanisms that reject anything that isn’t precisely right. Most residential locksmiths in Fremont rarely touch them. We do it daily. Kevin Yoon, owner at Preston Locksmith & Security, learned rekeying and cylinder work hands-on years before starting this shop, and he made a point of getting deep into Medeco, Mul-T-Lock, and Abloy platforms because Fremont homeowners and small-business owners kept asking for locks that actually hold up. So we stock genuine Medeco OEM cylinders, key blanks, and rebuild kits, and we keep them ready for same-day turnaround across Fremont. Real price on the phone. Same price at the door. That’s it.
Every job gets a written quote before work begins, a live trackable arrival time, before-and-after photos, and the 365-Day Done Right Promise: if it’s not done right, we make it right – in writing, on every invoice.

Common Medeco Locksmith Problems We Solve in Fremont
- Sticking or non-turning keys from fog and coastal air: Fremont’s overnight marine layer settles into lock cylinders. Over years, that moisture breaks down the factory lubricant inside Medeco Biaxial and M3 cylinders, leaving behind a gummy film that makes keys bind or refuse to turn. We pull the cylinder, clean the pin chambers, re-lubricate with a dry film lubricant, and re-pin if any wear shows up.
- Restricted keyway wear and failed key pinning: Medeco keys use angled cuts that contact pins differently than standard keys. When someone gets a copy cut on an aftermarket blank or a worn cutter, it slowly damages the pin stack. We re-pin using OEM Medeco pins and cut fresh restricted keys on the correct blanks.
- Sidebar binding on M3 and Biaxial cylinders: The sidebar and its tiny springs are the heart of Medeco’s pick resistance, but they’re also the first components to fail when dust or grit works its way inside. Homes near Fremont’s construction corridors and main boulevards see this more often. We strip, clean, and rebuild the sidebar assembly, and we’ll tell you plainly if replacement is cheaper than repair.
- Hardened faceplate and housing damage from forced entry: Burglary attempts on street-facing doors in older Fremont neighborhoods often leave the hardened Medeco faceplate intact but the internal housing cracked or the strike plate bent. We assess the cylinder, repair what’s salvageable, and replace what isn’t – with OEM parts when the integrity matters.
- Full deadbolt replacement on original 1960s – 70s door jambs: Newer Medeco Maxum deadbolts want a full 1-inch throw. Many older Fremont ranch homes were framed for shorter throws, so the bolt never extends fully into the strike pocket. We adjust or reinforce the strike plate so the deadbolt actually does its job. That’s the difference between a lock that looks secure and one that is.
Medeco Service in Fremont: What Local Conditions Mean for Your Equipment
Fremont has one structural quirk that shows up in Medeco work more than almost any other city in the Bay Area: the sheer volume of original 1960s and 1970s ranch homes with wood-frame door jambs that were never built for modern deadbolt geometry. A Medeco Maxum deadbolt is engineered around a full 1-inch throw. But on many of these older Fremont frames, the strike plate sits slightly forward, the jamb has settled, or the original cutout is too shallow – and the bolt never reaches its full depth. That means the deadbolt feels locked from the outside, but the actual load-bearing surface is only half what Medeco designed. It is a false sense of security, and it is extremely common in neighborhoods like Irvington, Glenmoor, and the older streets off Fremont Boulevard. We carry reinforced strike plates and longer screws as standard equipment because this scenario comes up on more than half of our Medeco replacements in Fremont. This is not a fix you’ll see listed on a generic Medeco service page, and it is the single biggest reason we recommend a quick in-person assessment even when the lock itself seems fine.

FAQs – Medeco Locksmith in Fremont
Can you rekey a Medeco lock to a different key in Fremont?
Yes. We re-pin Medeco cylinders with OEM Medeco pins and cut fresh restricted keys on the correct blanks through our Rekey Locks in Fremont service, usually in under an hour. If you’re not sure whether you want a full rekey or just a key copy, call (409) 405-4485 and we’ll help you pick the right option for your Fremont home or business.
My Medeco key is sticking – does that mean the lock is failing?
Not necessarily. It often means the factory lubricant has broken down from Fremont’s coastal humidity, or the key itself has worn down enough to stop aligning with the pins. We clean, re-lubricate, and inspect first. If the cylinder needs rebuilding, we’ll tell you before doing it. Call (409) 405-4485 and we’ll walk through what you’re seeing.
Do you stock Medeco high-security cylinders for immediate replacement?
Yes. We keep common Medeco Maxum, Biaxial, and M3 cylinders in stock for same-day replacement in Fremont. If we don’t have the exact finish or tailpiece on the truck, we can usually have it within one business day. Estimates are free.
Can you create a master key system using Medeco locks for my Fremont business?
Yes. We build Medeco master key systems for Fremont Commercial Locksmith clients including offices, retail stores, and small multi-unit buildings. This starts with a survey of your doors and a written scope, then we cut, pin, and deliver the system in one rollout. Call (409) 405-4485 to schedule a no-charge walkthrough.
What should I do if my Medeco lock was damaged in a break-in attempt?
Call us. Even if the faceplate looks intact, the internal housing or sidebar may be cracked. We’ll inspect the cylinder, repair what can be repaired, replace what can’t, and get the door securing properly the same day in Fremont. Pricing is given before we touch a single pin.
