Why San Bruno Residents Choose Us for Medeco Service

Medeco isn’t a lock you learn on the job. It’s a high-security system where every pin, sidebar, and keyway has to be exact or the cylinder won’t cooperate. Noel Carver, our owner and lead locksmith, cut his teeth on pin-tumbler work and automotive transponders before spending years on Medeco Biaxial, Maxum, and M3 systems. The difference shows when a San Bruno homeowner brings us a Medeco lock that’s been rekeyed six times and the key no longer centers properly. We don’t guess. We pull the cylinder, read the wear, and tell you whether re-pinning will hold or whether the cylinder body itself is done.

Most locksmiths in the Bay Area cap out at Schlage and Kwikset. We service Medeco sales & service across the full spectrum, from classic Medeco Original cylinders to current Maxum deadbolts. That matters in San Bruno because so many homes here run retrofit Medeco cylinders in doors that were never designed for them. You need a locksmith who understands both the lock and the old door it lives in. That’s us.

We’re also local to the peninsula. We know what the marine layer does to brass cylinders. We know which San Bruno streets still have original mortise hardware. And we know that when your front door won’t lock at 9 p.m., you don’t want to wait until tomorrow. Call (877) 265-4385 and you’ll get someone who knows this city’s hardware, not someone reading from a script.

Common Medeco Locksmith Problems We Solve in San Bruno

• Corrosion and sticking on west-facing doors. San Bruno’s marine layer pushes damp Pacific air into south- and west-facing entryways all year. Inside a Medeco cylinder, that moisture works into the pin chambers and sidebars. The key starts binding, then won’t turn at all. We clean, inspect, and re-pin these cylinders regularly. If the pins are too far gone, we replace them with genuine Medeco parts and lubricate graphite-free so the fix actually lasts.
• Worn mortise bodies in 1950s ranch doors. A huge share of San Bruno homes still carry the first lockset they ever had, an original mortise body that a Medeco cylinder was later retrofitted into. The cylinder itself may be fine, but the mortise body is sixty years old. Latch misalignment, bolt throw problems, and keys that turn without engaging the deadbolt all trace back to that worn case. We keep salvaged mortise cases from local tear-downs and can swap the body without tearing up the door.
• Restricted keyway wear from repeated rekeying. Medeco keys and keyways are precisely machined. After years of use and multiple rekeyings, the keyway itself wears and the original key stops centering. The cylinder needs re-pinning, and sometimes the plug needs replacement. We do both with genuine Medeco hardware, and we’ll cut new keys that actually feel right in the lock, not keys that wobble.
• Deadbolt strike misalignment on settled doors. San Bruno’s older homes sit on ground that shifts. Door jambs settle, and a deadbolt that used to throw cleanly now hits the strike plate edge-on. The cylinder turns fine, but the bolt won’t fully extend. That’s a strike alignment job, not a lock job. We fix the alignment and re-secure the strike so your Medeco deadbolt actually throws to full depth.
• Mixed-brand keying on Medeco retrofits. It’s common in San Bruno to find a Medeco cylinder on the front door and an original mortise lock on the back door. Homeowners want one key for both. That requires a locksmith who can assess the existing keyways and either re-pin both to match or tell you honestly when the old mortise lock can’t accept a Medeco cylinder. We’ll give you that answer upfront, then make it work if it’s possible.

Medeco Service in San Bruno: What Local Conditions Mean for Your Equipment

Here’s something about San Bruno that a generic Medeco page will never tell you. The post-WWII building boom built this city fast, between roughly 1945 and 1965. Those original ranch homes went up with mortise locksets you cannot buy at any big-box store today. Not any Home Depot, not any Lowe’s. The mortise bodies are obsolete sizes, and when one cracks or wears out, the standard playbook is to drill out the door and retrofit a modern deadbolt. That works, but it changes the door forever. Around here, good locksmiths keep something else on the truck: salvaged mortise cases pulled from tear-downs, cleaned up, and ready to accept a new Medeco cylinder. We keep a box of these on every San Bruno call. In newer neighboring cities like Millbrae where standard deadbolts dominate, nobody bothers. Here, it’s the difference between a clean fix and a door full of patch plates. If your home is one of the original ranches off San Bruno Avenue or near the Mills Park stretch, that old mortise lock is more serviceable than you’d think, provided the technician knows what’s in there.

The marine layer compounds it. Medeco cylinders are tight-tolerance machines. Constant damp air from the fog, especially on the south and west side of the house, works into the pin chambers. The result is a high-security lock that seizes up like a cheap Kwikset, and a homeowner who assumes the lock is junk. It’s not. It’s usually moisture and worn pins, both fixable. We see this on Medeco deadbolts and Medeco retrofits all over San Bruno service area, from the older neighborhoods near the BART corridor up toward the hills.

Medeco Models & Products We Service in San Bruno

We work on the Medeco lock you already have, not the one a sales guy wants to sell you. That covers Medeco Original, the classic high-security cylinder that still turns up on older San Bruno doors; Medeco Biaxial, the workhorse we see most often on retrofitted ranch homes; Medeco M3 cylinders, which add a second locking mechanism for bump and pick resistance; and Medeco Maxum deadbolts, the current generation of high-security residential hardware. We stock genuine Medeco pins, springs, and cylinders for fast turnaround, and for the vintage mortise bodies we’ve mentioned, we source salvaged or custom-machined cylinders that match the original door prep. If we can repair it, we will. If the mortise body is cracked or too worn to hold tolerances, we’ll tell you straight and recommend a modern Medeco deadbolt instead of a patch job that’ll fail in a year. Know your hardware, know your options – the rest is just turning a key.

FAQs – Medeco Locksmith in San Bruno

Can you rekey a Medeco lock on a 1950s San Bruno ranch home that still has the original mortise body? Yes, in most cases we can rekey the Medeco cylinder or cylinder assembly without replacing the mortise body underneath. The key is whether the mortise body still holds its tolerances. If it does, we rekey or repin the cylinder and you keep your original door hardware. If it’s cracked or the latch mechanism is sloppy, we’ll recommend a replacement and tell you why. Call (877) 265-4385 for a straight read on your specific door.

Why does my Medeco deadbolt stick only on the west-facing door of my San Bruno home? Because the west side of your house takes the brunt of the marine layer fog and damp Pacific air year-round. That constant moisture gets into the cylinder’s pin chambers and sidebars, causing the pins to bind and the key to stick. The east-facing door, shielded from the dominant damp airflow, stays dry and turns fine. We clean, lubricate graphite-free, and often re-pin the affected cylinder. It’s a recurring call in San Bruno and nearby Pacifica, and it’s fixable. Call (877) 265-4385 to schedule a service visit.

My Medeco key turns but the deadbolt won’t extend – what’s wrong? When the cylinder turns freely but the bolt doesn’t move, the problem is almost always downstream of the cylinder: a worn mortise body, a misaligned strike plate, or a broken tailpiece. This is common in San Bruno homes where the jamb has settled over decades. The fix is alignment work or a mortise body swap, not a new cylinder. We’ll diagnose it on the spot. For same-day help, call (877) 265-4385.

Do you stock replacement Medeco cylinders for older mortise locks that big-box stores don’t carry? We keep genuine Medeco cylinders on the truck, and for the obsolete mortise bodies that San Bruno’s 1950s ranches still have, we also carry salvaged mortise cases sourced from local tear-downs. That means we can often fit a new Medeco cylinder into an original door without drilling or patching. Big-box stores won’t have any of this. Call (877) 265-4385 and describe your lock; we’ll tell you what we can bring.

Can you key my Medeco front door and back door alike if the back has an original mortise lock? Sometimes. If the back door’s mortise body accepts a compatible cylinder, we can key both doors to the same Medeco keyway and cut matching keys. If the old mortise lock can’t accept a Medeco cylinder at all, we’ll tell you honestly and lay out your options, which may include replacing the back lock with a matching Medeco deadbolt. We won’t promise a one-key solution that the hardware won’t support. For an assessment, call (877) 265-4385.
