We service Medeco locks across El Cerrito (94530) as an independent shop, not a manufacturer affiliate, and also offer Medeco repair in Albany. Most calls we run here involve Medeco cylinders on older mortise locks or gate hardware that’s been fighting the Bay’s marine damp for decades. If your Medeco key sticks, won’t turn, or the deadbolt won’t throw, call Cypress Lock & Key at (877) 265-4385.
Our techs work on the Medeco lock you already have. That means re-pinning, rebuilding, and rekeying to genuine OEM spec rather than pushing a replacement you don’t need. For El Cerrito’s mix of 1940s-60s mortise locksets and hilly-doorframe settling, that repair-first approach matters.
If you need Medeco sales & service from a shop that stocks the full pin and cylinder line, we’re your local option. We quote the full price on the phone before anyone rolls out. Call (877) 265-4385.
Why El Cerrito Residents Choose Us for Medeco Service
Medeco isn’t a lock you hand to a generalist who’s never opened one. The Biaxial and M3 cylinders use angled cuts and sidebar mechanisms that punish guesswork. We’ve rebuilt enough of them across El Cerrito’s hills and flats to know what fails and why.
Noel Carver, our owner, came up through a locksmithing and security systems program at Fresno City College and has been working on high-security hardware in the Bay Area for close to two decades. Medeco’s tight tolerances are exactly what he likes about them. When a cylinder gets gritty from fog-driven corrosion, the fix is methodical and specific, not a squirt of graphite and a shrug.
We’re independent. That means we stock genuine Medeco pins, cylinders, and restricted key blanks without having to route every job through a manufacturer warranty channel. We service Medeco, Mul-T-Lock, Abloy, Schlage, Kwikset, Baldwin, Yale, and Sargent, so the tech who shows up at your El Cerrito door isn’t learning your lock on the fly. As Noel puts it: “Know your hardware, know your options – the rest is just turning a key.”
We serve all of El Cerrito service area, from the flats along San Pablo Avenue up into the hillside streets where door alignment is a seasonal sport.

Common Medeco Locksmith Problems We Solve in El Cerrito
Medeco hardware is built to resist picking and bumping. The problems El Cerrito throws at it are environmental and structural, not criminal. Here’s what we see week after week:
- Stiff or gritty cylinders from marine corrosion. Original Medeco cylinders on 1940s-60s mortise locks sit in exterior doors that catch fog off the Bay nine months a year. Pins corrode, springs bind, and keys start to stick or refuse to turn. We disassemble, clean, and re-pin rather than condemn the lock.
- Deadbolts that won’t throw after the house settles. El Cerrito sits on Hayward Fault country, and the 2010s quakes plus normal settling leave door frames out of square. The Medeco cylinder is fine, but the bolt contacts the strike plate wrong and won’t extend. We realign the strike and reinforce the jamb so the hardware works again.
- Seized gate and exterior cylinders on hillside lots. Up around Arlington and the Berkeley Country Club area, front steps and side gates face direct weather. Medeco gate cylinders corrode and seize while the interior locks stay smooth. We see this pattern constantly on sloped lots.
- Restricted keyway systems with missing key control cards. Older Medeco systems rely on a card to authorize key duplication. When that card’s gone and pins are worn, getting a new key is a mess. We decode, rebuild, and re-pin the cylinder so duplication works again.
- Worn pins in high-use Medeco Maxum deadbolts. The Maxum line gets put on front doors that get opened four, five, six times a day. Over years, pins wear unevenly. We re-pin to OEM spec rather than replace the entire lock.
Medeco Service in El Cerrito: What Local Conditions Mean for Your Equipment
El Cerrito’s hillside streets like Arlington sit on sloped lots where front-door steps and side gates face the street. That single fact changes how Medeco locks fail here. In a flatland subdivision, a Medeco cylinder on the front door fails from use. In El Cerrito, the first Medeco lock to go is almost always on the gate or an exterior service door, because those get the full brunt of marine fog, winter damp, and sun on the western slopes. The interior-side knob turns fine for years; the gate cylinder seizes solid.
We ran this exact call on a foggy morning in the Arlington area, and we provide Medeco service in East Richmond Heights too: a Medeco Maxum deadbolt on a 1950s ranch home where the bolt wouldn’t throw because the door had settled and the strike was misaligned. After realigning the strike and reinforcing the jamb, we re-pinned the Maxum cylinder to a new restricted keyway. The homeowner also asked us to rekey the side gate Medeco cylinder, which had seized from years of marine damp. Two different failures, one house, both from El Cerrito’s geography. That’s the pattern. Flatland shops don’t expect it. We do.
Medeco Models & Products We Service in El Cerrito
We work on the full Medeco residential and light commercial range that’s common in El Cerrito’s housing stock:
- Medeco Maxum – the heavy deadbolt you see on mid-century front doors, often paired with original mortise locks. We rebuild, re-pin, and realign these.
- Medeco Biaxial – the workhorse high-security cylinder. We cut keys, decode worn pins, and rebuild cylinders to your original keyway.
- Medeco M3 – the newer generation with upgradeable key control. We handle rekeys, key duplication, and cylinder service.
- Medeco Original – the classic that started the high-security name. We service and re-pin these, especially on older mortise locks where the lock body is worth keeping.
All parts we install are genuine Medeco OEM: pins, cylinders, sidebar springs, and restricted key blanks. No aftermarket substitutes. If a cylinder can be re-pinned or rebuilt to spec, that’s what we do. On vintage mortise locks from the 1940s and 50s, the lock body itself is often superior to anything you’d buy new, so we keep it and upgrade the cylinder.

FAQs – Medeco Locksmith in El Cerrito
Usually it’s the door. El Cerrito’s wet winters swell wood and shift frames, so the bolt no longer aligns with the strike plate even though the cylinder turns fine. We check both on-site: if the cylinder rotates smoothly with the door open, the problem is frame alignment, not Medeco internals. Call (877) 265-4385 and we’ll diagnose it properly.
Yes. The mortise lock body from that era is often solid brass and worth keeping. We pull the Medeco cylinder, re-pin it to a new key, and put it back in the original body. You keep the vintage hardware and get modern key control.
Maxum deadbolts on mid-century front doors, Biaxial cylinders on rental and small-commercial properties, and the occasional M3 on newer replacements. Original Medeco cylinders show up on the oldest locks that were retrofitted decades ago.
We can decode and re-pin a restricted cylinder to a new keyway and issue you duplication authorization going forward. If you’ve lost the original key control card, we’ll set the cylinder up so key duplication is controlled again through our shop.
Almost always yes. We disassemble the cylinder, clean the corrosion, replace any worn pins with OEM Medeco parts, and rekey it while we’re there. Hillside gate locks in El Cerrito seize constantly from marine damp, and on-site service is faster than you’d think. Call (877) 265-4385 for a quote.
