Cypress Lock & Key handles the full Medeco line: Maxum deadbolts, Biaxial cylinders, M3 restricted keyways, and the classic Original high-security cylinder. We service what’s already on your door, and we do it across Pleasant Hill without sending you to a manufacturer-authorized shop that may be two cities away. Medeco sales & service is a core part of what we do, not a side line.

Why Pleasant Hill Residents Choose Us for Medeco Service

Medeco cylinders are not Schlage or Kwikset. The rotating-pin design that makes them pick-resistant also makes them sensitive to improper servicing. You can’t just dump WD-40 into a Biaxial and call it fixed, and you can’t cut a duplicate Medeco key on the machine at the hardware store.

We’ve spent years installing, re-keying, and repairing Medeco high-security cylinders and restricted-keyway systems across Contra Costa County as an independent shop, including Contra Costa Centre Medeco service. No manufacturer authorization, no dealership agreement. Just deep familiarity with how Medeco’s rotating-pin designs actually behave in the field. When we say a Medeco cylinder needs rebuilding rather than replacing, it’s a judgment earned on real doors, not a sales script.

Noel Carver, our owner and lead locksmith, completed a locksmithing and security systems program at Fresno City College and has been running calls in this part of the state for close to two decades. The thing customers mention most is that he shows up calm and reads the problem before reaching for a drill. That matters on a high-security lock where a hasty repair can turn a $150 rekey into a $400 cylinder replacement. If you’re in Pleasant Hill, we’re your local option for Pleasant Hill service area coverage with genuine Medeco parts on the truck.

Common Medeco Locksmith Problems We Solve in Pleasant Hill

• Rotating-pin chambers gumming up on exterior Maxum and Biaxial cylinders. Pleasant Hill’s hot, dry summers followed by mild, wet winters push fine dust and moisture into cylinder bodies. The key inserts but won’t turn smoothly because those pins aren’t rotating the way they should. We disassemble, clean, and re-lubricate with the right product for Medeco’s tight tolerances, not a general-purpose spray.
• Seasonal wood-door swell throwing the deadbolt out of strike alignment. This is the number-one Medeco call we get in Pleasant Hill, and the cylinder is rarely the culprit. The original single-cylinder deadbolt on a 1960s townhome or ranch entry binds because the wood frame has moved through the wet season. The fix is strike and door-edge adjustment, not a cylinder swap. We see it every spring.
• Worn or missing pinning cards and lost restricted keys on Biaxial and M3 systems. When control keys walked off decades ago, you can’t just duplicate from a spare. We decode the cylinder, map the pinning, and rebuild the keying from scratch. Then we issue new restricted keys and new cards. It takes longer than a standard rekey, but it keeps your controlled keyway intact.
• Vintage mortise-style or early tubular locksets in older Pleasant Hill ranches that were never designed for a modern high-security cylinder. The Medeco core won’t seat without hand-fitting or pocket adaptation. We’ve done this often enough in the Gregory Gardens area and the blocks near downtown that we know what the door prep looks like before we arrive.
• Builders who installed Medeco hardware but never explained the key-control system to the new owner. You bought a Pleasant Hill townhome with a Medeco Biaxial on the front door and no idea that keys are restricted, meaning you can’t get duplicates without the proper card. We rekey the cylinder, set you up with new restricted keys, and walk you through how the system works. No upsell, just information.

Medeco Service in Pleasant Hill: What Local Conditions Mean for Your Equipment

Here’s what actually decides whether a Medeco retrofit works in Pleasant Hill, and it’s not the lock itself.

Pleasant Hill’s downtown-adjacent and Gregory Gardens ranches often still hold original mortise-style or early tubular locksets whose door prep doesn’t match a modern deadbolt bore. A drop-in deadbolt swap assumes a 2-1/8-inch cross bore and a 1-inch edge bore. Those older doors frequently have neither. So a Medeco upgrade here frequently means fitting a high-security cylinder into an adapted or re-machined pocket, done by hand on-site, rather than the clean deadbolt installation that a newer subdivision on the city’s edges would allow. This is the single biggest difference between Medeco repair in Pacheco or Pleasant Hill and Medeco work in a neighboring city like Walnut Creek, where decades of teardowns have erased much of that original door prep.

Add in the seasonal wood-swell cycle and you have a specific local picture. The hot, dry summers and wet winters cause wood doors and frames to swell and stick. A Medeco cylinder with tight internal tolerances will show that misalignment faster than a sloppy builder-grade knob would. Most of our Medeco calls here are not failed cylinders. They’re failed door geometry that happens to be wearing a Medeco.

We had a Gregory Gardens homeowner call because her front-door key would turn halfway and stop. She assumed the Medeco Maxum had failed. What we found was a 1950s ranch door with the original mortise-style prep, a jamb that had swelled through the wet season, and a Maxum bolt binding hard against a strike plate that had shifted a quarter-inch over sixty years. We pulled the cylinder, cleaned and repinned it, re-machined the strike to the new bolt line, and reinforced the jamb face. Her restricted keyway and original hardware stayed, and the door threw clean. That’s the kind of Medeco work Pleasant Hill actually needs.

Medeco Models & Products We Service in Pleasant Hill

We service the full Medeco residential and light-commercial line that shows up on Pleasant Hill doors:

• Medeco Maxum deadbolt: the heavy-duty single-cylinder deadbolt common on upgraded ranch and townhome entries. We rebuild, rekey, and reinstall these regularly.
• Medeco Biaxial cylinder: the classic rotating-pin, pick-resistant core found on many mid-century retrofits. We stock Biaxial pins and restricted blanks.
• Medeco M3 (Medeco3) restricted keyway: the current restricted system with key-control cards. We can rekey, issue new keys, and rebuild without your original card.
• Medeco Original (classic) high-security cylinder: older units still in service on some Pleasant Hill homes. Parts are harder to source; we know which components remain available and which need a retrofit path.

Our parts stance is straightforward. We use genuine Medeco cylinders, pins, and restricted key blanks for anything touching a high-security core. We only reach for quality aftermarket deadbolt bodies or strike hardware where the door prep is the problem rather than the lock. If a Medeco cylinder can be cleaned, repinned, or rebuilt to keep its restricted keyway intact, we rebuild it. Replacement is a last resort, not a default.
