We’re an independent Medeco locksmith serving San Lorenzo, CA. We pin, re-key, rebuild, and install Medeco cylinders and deadbolts across 94580, including restricted-keyway systems most shops won’t touch. What makes our Medeco work different here: San Lorenzo’s housing stock went up in one tight postwar build-out, so the same builder-grade door prep shows up on thousands of nearly identical tract homes. That means we know exactly what a Medeco retrofit looks like on your door before we even arrive. Call (877) 265-4385 for a free estimate.
Why San Lorenzo Residents Choose Us for Medeco Service
Medeco isn’t a side project for us. We work on the lock you already have, and over the years that’s meant pinning, re-coring, and rebuilding Medeco cylinders on East Bay tract-home doors that were never designed for high-security hardware. The restricted keyway systems especially: most big-box shops won’t touch them because the key blanks are controlled and the pinning takes patience. We’re an independent shop, not tied to Medeco, so our only obligation is getting the cylinder to work with the door you actually have.
We’re local to San Lorenzo. Noel Carver, our owner, has been running calls in this part of the East Bay for nearly two decades, and the thing customers mention most is that he shows up calm. No drama about the lock being “beyond repair,” no upsell pressure. Just a clear read of the problem and a clean fix. Medeco sales & service is a core part of what we do, and the tract-home doors in San Lorenzo are about half of that work. When you call, you get someone who’s already re-keyed your neighbor’s identical floor plan.

Common Medeco Locksmith Problems We Solve in San Lorenzo
- Retrofitted Medeco cylinders in original 1950s-70s mortise and builder-grade deadbolts. The wood slabs on these ranch homes have swollen and shifted over five decades. The Medeco cylinder itself is fine; the bolt drags or won’t throw until the strike is repositioned. We fix the alignment before touching the cylinder.
- Sticking deadbolts in damp East Bay winters. San Lorenzo gets rainless summers and damp winters, which means exterior locks face seasonal moisture rather than freeze damage. The finish weathers, the strike drifts, and the deadbolt sticks. Usually the cylinder isn’t the culprit, and we’d rather tell you that than sell you a rebuild you don’t need.
- Broken key control on rental-turnover Medeco cylinders. Restricted-keyway Medeco cylinders are common on rental properties in 94580. When the previous tenant’s keys and key-control card walk off, the cylinder works but key control is gone. We rebuild and re-key it so the old keys become useless.
- Worn pin chambers and keyway debris on heavily cycled front-door cylinders. Older tract homes in San Lorenzo see decades of daily use. Keys start to catch or stick even after a routine re-key. We clean, re-pin, and replace worn springs with genuine Medeco components.
- Medeco retrofits on aging garage side-doors. Many San Lorenzo homes have original garage side-doors with hardware that’s barely holding the jamb together. We can tell you straight whether the door is worth retrofitting with a Medeco high-security deadbolt or whether the slab itself needs work first. If the door can’t hold the core, we’ll say so.
Medeco Service in San Lorenzo: What Local Conditions Mean for Your Equipment
San Lorenzo is unincorporated and master-planned, built out almost entirely in the tight postwar window between the 1950s and 1970s. There’s no real downtown to speak of, and the work here isn’t driven by commercial storefronts. It’s driven by resale churn and rental turnover along the 94580 corridors: the same few original knob-lock and builder-grade deadbolt setups appearing again and again across the tract. For Medeco owners that’s actually an advantage. A retrofit here is a known, repeatable pattern rather than a one-off measure-and-fit. On a stretch of tract homes off Hesperian Boulevard, a homeowner called because the Medeco Maxum deadbolt on a 1960s ranch front door had started catching halfway. For those seeking Medeco in San Leandro, similar retrofit issues are common in nearby postwar tracts. The cylinder was fine, but the swollen wood slab and settled strike had thrown the bolt out of line. We reset the strike, reinforced the jamb, and re-cored and re-keyed the Maxum to a fresh restricted key while we were in it. The neighbor two doors down, same floor plan and same builder deadbolt, booked the same swap the same week. That’s how word of mouth moves here: one re-key cascades into a whole block.
Medeco Models & Products We Service in San Lorenzo
We pin and rebuild the Medeco Original classic deadbolt, the Biaxial cylinder, the M3 (Medeco3) high-security cylinder, and the Maxum deadbolt. We use genuine OEM Medeco pins and springs, and we use OEM or quality aftermarket cylinders only where the original body truly can’t be saved. If a vintage mortise or worn builder deadbolt won’t reliably hold a Medeco core, we tell you straight and recommend the replace rather than sell a re-key that won’t last. We stock the common Medeco pin kits and key blanks locally so San Lorenzo calls don’t wait on parts shipping.
Medeco Service Pricing in San Lorenzo
Medeco service in San Lorenzo is priced by the job, not by a teaser rate that changes when the tech arrives. Our work includes the specific Medeco model or cylinder type you have, its condition, and whether we’re re-keying, rebuilding, or doing a fresh install to a high-security deadbolt. A full re-key is often the most cost-smart move when a tenant leaves or a key set goes missing: you change who has access without buying new hardware. A free estimate includes a straight read on whether your existing door can hold a Medeco core or needs strike or jamb work before the lock goes in. The number we quote on the phone is the number on the invoice – no dispatch surcharge, no arrival fee surprise. Call (877) 265-4385 for an exact quote, and we’ll walk you through what your San Lorenzo door actually needs.

FAQs – Medeco Locksmith in San Lorenzo
Yes. We re-key Medeco cylinders in San Lorenzo all the time for exactly that reason: rental turnover along the 94580 corridors is constant, and unreturned keys break key control. We re-pin the cylinder to a fresh restricted key and clear the old key’s access. If the key-control card is gone, we handle that too. Call (877) 265-4385 and we’ll schedule it.
Usually not. Damp East Bay winters cause the wooden door slabs on San Lorenzo ranch homes to swell, and the strike plate drifts just enough that the bolt drags. The Medeco cylinder itself is often fine. We check the alignment first and only rebuild the cylinder if it’s actually worn. Call (877) 265-4385 and we’ll give you a straight diagnosis.
In most cases, yes. The original mortise and builder-grade cylindrical bodies in San Lorenzo’s tract homes are standardized enough that a Medeco retrofit is predictable. The bigger question is whether the door slab and strike still hold alignment after decades of settling. We measure and tell you before we cut anything. Call (877) 265-4385 for a free estimate.
Yes. We do it often, and we’ll tell you straight if the door slab or jamb needs reinforcement before the Medeco deadbolt goes in. On older San Lorenzo tract homes, the garage side-door is sometimes the weakest entry point, and a high-security deadbolt only helps if the door behind it is solid. We handle both the hardware and the honest assessment. Call (877) 265-4385 to schedule.
Yes, and it happens here more than anywhere else we work. San Lorenzo’s identical postwar floor plans mean one Medeco swap often turns into two or three on the same block. We’ve re-keyed entire stretches of tract homes after a single neighbor recommended us. Call (877) 265-4385 and we can coordinate a block-wide re-key.
