We’re an independent Seattle locksmith shop that services Medeco locks across the city, from Medeco service in White Center and Pioneer Square storefronts to Queen Anne hillside homes. What makes our Medeco work here different is simple: we stock the cylinders, pins, and restricted keyway blanks that Medeco owners actually need, and we know how Seattle’s wet season and shifting hillside door frames beat up high-security hardware. We’re not authorized by Medeco, which means our repair-versus-replace advice is driven by what we find in the door, not by what a manufacturer tells us to sell. Call (855) 473-2502 if you’ve got a Medeco lock that’s fighting you.
Our Medeco sales & service work covers everything from a single deadbolt rekey to a full restricted-keyway system for a commercial building. Norm Eckley, who runs Belmont Lock & Key, has been working on Medeco hardware long enough that he’ll tell you the same thing he tells every customer: “Tell me what you’ve got – I’ve probably seen it before.” And in Seattle, he means it. We serve the whole Seattle service area with the same straight answer on cost and timing that we’d give a neighbor.
Why Seattle Residents Choose Us for Medeco Service
Medeco is not a lock you hand to just any locksmith. The Biaxial and Medeco³ cylinders use angled cuts and a sidebar that most shops never see because most shops never stock the parts. We do. Norm came up through Bates Technical College’s locksmithing program, where an instructor hammered home that high-security work is equal parts puzzle-solving and people work. He never forgot that. When a Seattle homeowner calls with a Medeco Maxum deadbolt that’s gone stiff, our people know how to open it, clean it, and get it turning smooth again without tearing up the door.
Being local matters because Medeco service in Seattle involves weather patterns that a technician three counties away won’t anticipate. We rekey, repair, and maintain Medeco locks across all four Seattle ZIP codes we cover: 98145, 98146, 98148, and 98154, including Medeco in Medina. The full price is quoted on the phone before anyone is dispatched, and that’s the price on the invoice. No call-out surcharge added on arrival.

Common Medeco Locksmith Problems We Solve in Seattle
- Corroded exterior keyways from the wet season. Seattle’s long rainy months put moisture into every exterior keyway, and Medeco’s tight tolerances mean that corrosion shows up as a dragging key long before the lock actually fails. We clean and re-lubricate the cylinder, and if the keyway’s too far gone, we rekey to fresh OEM pins and springs.
- Swollen door slabs and shifted jambs on hillside homes. On the steep streets of Queen Anne and West Seattle, the same house can have a street-level entry and a below-grade basement door, both keyed alike to one restricted Medeco key. When the wet season swells the wooden slab, the deadbolt binds in the strike and the lock gets blamed for what’s actually a frame-alignment problem. We realign and reinforce rather than replacing a sound cylinder.
- Worn or lost restricted Medeco keys. Because the keyway is patented, you can’t just walk into a hardware store for a blank. Blanks must come through the right channel, and rekeying a whole Medeco system is a bigger job than a Kwikset rekey. We stock restricted blanks locally so we can cut and program new keys for most Medeco systems without a multi-week wait.
- Loose Medeco retrofits in 1900s-1920s Craftsman doors. Seattle’s older housing stock includes plenty of four-squares and bungalows with original mortise locks. When someone retrofits a Medeco cylinder into a mortise pocket cut for a smaller lock, it can work loose over time. We see this in the Central District and other old-home neighborhoods regularly, and the fix is usually a proper reinforcement plate and a fresh installation.
- Commercial storefront Medeco systems in Pioneer Square retrofit buildings. Seattle’s seismic retrofit mandates in unreinforced masonry zones often require upgrading door frames and hardware. When contractors upgrade a Pioneer Square storefront, we coordinate with them to make sure the Medeco restricted-keyway system stays functional through the structural work.
Medeco Service in Seattle: What Local Conditions Mean for Your Equipment
Here’s the thing about Seattle that most generic Medeco advice misses: it’s the wet season, not cold, that kills exterior cylinders here. Months of rain and high humidity corrode keyways, swell wooden door slabs so deadbolts bind, and turn a small misalignment into a lock that won’t throw. In the Sun Belt, locksmiths schedule for heat damage. Here, we schedule for moisture. Norm grew up near the Key Peninsula and learned early that anything metal left outside in western Washington is going to fight you eventually, which is why we also offer Medeco repair in Yarrow Point. A homeowner on a steep Queen Anne street called us because her street-level Medeco Maxum had gone stiff while the below-grade basement door, keyed alike to the same restricted key, still turned fine. We found the street door’s wooden slab had swollen from the wet season and the jamb had shifted. We realigned the strike, reinforced the frame, cleaned and re-lubed the Maxum cylinder, and rekeyed both doors back to one Medeco key. That’s not a lock failure. That’s a Seattle door problem, and you can’t fix it by swapping the cylinder.
Medeco Models & Products We Service in Seattle
We work on the full Medeco high-security range: the Maxum deadbolt, the M3 cylinder in both original and patented-keyway versions, Biaxial and Medeco³ cylinders, and Medeco KeyMark restricted commercial keyway systems. For any patented keyway, we use genuine Medeco OEM cylinders, pins, springs, and restricted key blanks. For non-security trim like strikes and reinforcement plates, we use quality aftermarket hardware where it makes sense. On a sound Medeco cylinder, we rekey, clean, and re-lube rather than selling a replacement. We recommend replacement mainly when the body is cracked, the keyway is worn out, or the door has moved enough that the cylinder can’t be aligned. Because we stock Medeco parts locally in Seattle, turnaround on a standard rekey is usually same-day, not a catalog-and-wait.
Medeco Service Pricing in Seattle
Medeco service in Seattle typically lands between $150 and $450, depending on what you’re dealing with. A straightforward rekey of a single Medeco cylinder runs on the lower end. A full restricted-keyway system rekey for a commercial storefront is a different job entirely and costs more. Replacing a Medeco Maxum deadbolt sits mid-range, while door reinforcement and frame realignment add cost on top of the lock work. The honest answer is that we quote the full price on the phone before anyone is dispatched, and it’s the price on the invoice. No added call-out surcharge when we arrive. Call (855) 473-2502 for a free estimate on your specific Medeco lock, and we’ll tell you what it’ll cost before you commit to anything.

FAQs – Medeco Locksmith in Seattle
Yes, and this is exactly why we stock restricted Medeco key blanks locally. Because the keyway is patented, you can’t get blanks at a hardware store. We can cut and program new keys for most Medeco restricted systems in a single visit. Call (855) 473-2502 and tell us the keyway type stamped on your key, and we’ll confirm we can cut it before you come in.
Usually not. What you’re feeling is almost always the door slab swelling from Seattle’s wet season and torquing the bolt against the strike plate. The Medeco cylinder itself is probably fine. We realign the strike, reinforce the frame if needed, and clean and re-lube the cylinder. That’s typically a $150-$250 call, far less than replacing a perfectly good high-security deadbolt. Call (855) 473-2502 and we’ll diagnose it over the phone before we dispatch.
In Seattle’s 1900s-1920s Craftsman homes, the original mortise lock is often in decent shape but the keyway is worn and easily picked. Converting to a Medeco mortise cylinder gives you a restricted keyway and much better pick resistance without tearing out the original hardware. The catch: the mortise pocket was usually cut for a smaller lock, so the retrofit has to be done carefully or it’ll work loose. We reinforce the pocket and install fresh hardware. Call (855) 473-2502 for an honest assessment of whether your specific door is a good candidate.
We can, with a caveat. Medeco uses a different keyway than Schlage or Kwikset, so a single physical key won’t operate all three. What we do instead is create a master key system or a keyed-alike set within each brand, then put them on the same keyring. If you’re in Seattle and want one-key convenience with high security on your main entry, that’s the practical route. Call (855) 473-2502 and we’ll map out what it looks like for your doors.
If the building is in Seattle’s unreinforced masonry retrofit zone, the door frame and hardware may be scheduled for upgrade as part of the seismic mandate. Don’t replace the Medeco lock in isolation; coordinate the lock work with the frame reinforcement so you don’t pay twice. We work with contractors on Pioneer Square storefronts regularly and can handle the Medeco repair in Clyde Hill and the Medeco side while the structural work happens. Call (855) 473-2502 and we’ll look at the full picture.
