We’re not a Medeco dealer and we don’t pretend to be. What we are is a crew that has taken apart, re-pinned, and resurrected enough Medeco cylinders to know them from the inside out. Medeco sales & service is a core part of what Glendale Lock & Key does, and in Upland that means working on locks that have lived through fifty Santa Ana seasons and a hundred degree Julys.

Why Upland Residents Choose Us for Medeco Service

Most locksmiths in this area can rekey a Schlage. Far fewer can sit down with a sticky Medeco Original cylinder from a 1940s bungalow, diagnose worn springs and a misaligned strike, and have it turning smoothly again in the same visit. Noel Tarkanian, our owner and lead technician, learned pin-tumbler mechanics from his uncle’s apartment rekeys growing up in Glendale, then put in formal training through the locksmithing and security technology coursework at Glendale Community College. He’ll name the cylinder, point out the tolerance issue, and fix it. No drama.

We carry OEM Medeco parts whenever they’re available: pin kits, springs, tailpieces, strike plates. When a discontinued Original cylinder needs aftermarket springs, we source ones that meet or exceed spec rather than whatever fits. That matters in Upland, where the housing stock spans from 1920s Craftsman mortise locks to electronic keypad deadbolts on east-side tract homes. Same technician, same truck, both jobs. Our Upland service area covers 91784, 91785, and 91786.

Common Medeco Locksmith Problems We Solve in Upland

• Summer deadbolt binding from frame warp. Upland’s hot, dry summers and Santa Ana wind events pull moisture out of wood door frames. The frame bows, the bolt no longer lines up with the strike, and a Medeco Maxum deadbolt that worked fine in March suddenly won’t throw without a fight. We realign the strike, shim the hinge if needed, and restore clean operation. Sometimes the lock was never the problem. The door moved.
• Sticking keys in original Medeco locks on downtown bungalows. The 1920s-40s homes near Euclid Avenue often still have their original mortise locksets with Medeco cylinders that are decades old. Worn pins and tired springs make keys stick, drag, or fail to turn entirely. We re-pin these on-site with OEM or matching-spec parts and cut spare keys before we leave.
• Battery corrosion and keypad wear on foothill smart locks. The hillside properties in San Antonio Heights see bigger temperature swings and more dust than the valley floor. Medeco electronic keypad locks up there fail more often from corroded battery terminals and worn keypad membranes than from anything mechanical. We clean terminals, replace membranes where possible, and reprogram as needed.
• Key breakage in commercial M3/M4 cylinders. Older commercial buildings in Upland often have Medeco M3 or M4 cylinders that have never been lubricated. Debris builds up in the keyway, the key gets harder to turn, and eventually it snaps. We extract the broken key, flush the cylinder, and re-pin if the damage goes deep. Most of these cylinders are still worth saving.
• Lost or un-duplicable restricted keys. Medeco restricted keyways can’t be copied at a hardware store, and Upland homeowners discover this at the worst possible moment. We hold the key blanks locally, verify ownership, and cut replacements the same day. You don’t have to mail a form to the factory and hope.

Medeco Service in Upland: What Local Conditions Mean for Your Equipment

The Euclid Avenue corridor holds a concentration of 1930s-50s homes with original Medeco mortise locks using restricted keyways that big-box stores can’t touch. These aren’t just old locks. They’re high-security hardware installed before Upland’s orange groves gave way to tract housing, and many still work as well as they did when they were installed. The catch is that they need a locksmith with the right key blanks, the right pin kits, and the patience to service a seventy-year-old mortise body rather than drill it out and sell you something new. We keep that patience and those parts on the truck.

Last Santa Ana week, we took a call at a 1940s Spanish Colonial bungalow just east of Euclid. The original Medeco mortise lock had jammed solid. The door jamb had warped in the dry wind and the bolt was binding against the strike plate. We adjusted the strike, re-pinned the cylinder with OEM springs, and cut two spare keys on-site. The century-old hardware never came off the door. That’s the job done right in Upland.

Medeco Models & Products We Service in Upland

We work on the full Medeco lineup you’re likely to find in Upland homes and small commercial spaces. The Maxum deadbolt is common on foothill estate doors and newer east-side builds. The M3 and M4 cylinders show up on office suites and commercial storefronts throughout the city. The Original high-security cylinders and mortise locks are what we pull from downtown bungalows, and KeyMark systems appear in some HOA gate access and multi-unit settings. High Security Locks, Lock Rekey, and Smart Lock Installation are the three services that come up most on Medeco calls.

Parts policy: OEM whenever possible, especially for restricted keyways and high-security pin kits. For discontinued vintage Medeco Original cylinders, we source aftermarket springs and pins that meet or exceed factory spec. We recommend repair over replacement whenever the cylinder body and keyway are intact. Preserving the security you already paid for beats selling you something you don’t need.

FAQs – Medeco Locksmith in Upland

Can you cut keys for my Medeco lock on Euclid Avenue that the hardware store says they can’t duplicate? Yes, we can. Hardware stores don’t carry Medeco restricted keyway blanks, and they’re not authorized to order them. We stock common Medeco blanks locally and can verify ownership, cut the key, and test it in your lock the same day. Call (855) 791-2710 and describe the keyway; we’ll tell you if we have the blank on the truck.

Why does my Medeco deadbolt stick only in summer and winter? Upland’s climate is brutal on wood doors. Dry summer heat and Santa Ana winds pull moisture from the frame, which warps and shoves the strike plate out of alignment. Winter rain swells the door back, but often in a slightly different position. Your Medeco cylinder is usually fine when this happens. The fix is strike plate adjustment, hinge shimming, or minor frame work. We diagnose the actual cause rather than replacing a cylinder that isn’t the problem.

Do you service Medeco smart locks in San Antonio Heights? Yes. We work on Medeco electronic keypads and smart deadbolts throughout the foothills, including San Antonio Heights and the gated communities north of Foothill Blvd. Battery terminal corrosion from temperature swings and keypad membrane wear from dust are the two most common failure points we see up there. Call (855) 791-2710 for an exact quote; estimates over the phone are free.

My Medeco M3 cylinder is stiff. Can it be repaired or does it need replacement? Most stiff M3 cylinders are repairable. The usual culprits are debris in the keyway, dried-out lubricant, or worn pins. We flush the cylinder, re-pin with OEM parts if needed, and re-lubricate. Replacement is only necessary when the cylinder body itself is cracked or the keyway is physically deformed. We’ll show you the inside before we recommend anything.

Are you authorized by Medeco? No, and we’re straightforward about that. We’re an independent locksmith. Our Medeco knowledge comes from hands-on service work on real cylinders in real Upland homes, not from a manufacturer credential. If your system requires dealer-level card access programming or factory key control administration, we’ll say so honestly. For repair, rekey, key cutting, and installation, we handle it in-house.
