Medeco Locksmith in Seattle, WA | Strongbox Lock & Safe Co. of Washington
Medeco lock service in Seattle typically runs $180-$450 depending on whether you need a rekey, cylinder rebuild, or full deadbolt replacement, and we stock genuine Medeco OEM parts for same-day completion on most jobs. What sets our Medeco work apart in Seattle is how we account for the city’s marine climate - the same humidity that swells your door frames each October also corrodes Medeco’s precision brass components, and we’ve learned to diagnose both problems in one visit rather than chasing symptoms. We are independent Medeco specialists, not manufacturer-authorized, with over 15 years of hands-on experience across Seattle’s neighborhoods from Capitol Hill to White Center. Call (888) 545-8474 for a flat price before we roll.
Why Seattle Residents Choose Us for Medeco Service
Dennis Wakefield grew up in the Courthouse Hill neighborhood and has spent the better part of three decades learning every door, deadbolt, and safe in this town. He picked up the trade at Washington County Community College, where a night-course instructor showed him that a well-cut key is as much about precision as patience - a lesson that stuck. That patience matters with Medeco. These locks are unforgiving of sloppy pinning or aftermarket shortcuts.
We carry the full line of Medeco tools and parts locally, including OEM pins, springs, and sidebar components for Biaxial, M3, Maxum, and MTL cylinders. Our technicians complete Medeco-specific training and present ID at your door in uniform. We quote the price before the truck moves. That’s just how this should work.
Seattle’s housing stock - those 1905-1940 Craftsman bungalows and foursquares with original mortise hardware - demands a locksmith who understands both vintage door prep and modern high-security retrofit. We’ve installed Medeco deadbolts in homes where the door frame was older than most of our competitors’ companies, which is why homeowners trust our Residential Locksmith in Seattle expertise. And we back every job with our 90-Day Done Right Promise in writing - no paperwork to file, no argument if something needs adjusting.
Common Medeco Locksmith Problems We Solve in Seattle
- Corroded brass pins and sidebar springs from marine humidity. Seattle’s 150-plus rainy days per year push moisture into exterior Medeco cylinders, particularly on north-facing entries in Fremont and Wallingford. The fine brass pins develop surface oxidation that causes intermittent binding - the key works fine at noon, sticks at 6 a.m. We disassemble, clean with Medeco-specific solvents, and replace with OEM pins and springs.
- Deadbolt misalignment from seasonal frame swelling. Every autumn, we field calls from Capitol Hill and the Central District where swollen wood frames push Medeco Maxum deadbolts hard against strike plates. Repeated forcing strips the hardened steel bolt edge. We adjust strike placement and check bolt throw - sometimes shaving the strike mortise, sometimes recommending seasonal maintenance before the damage sets in.
- Lost master keys forcing full building rekeys. In older Capitol Hill apartment buildings still running 1950s-60s master-key systems, one lost tenant key can legally and practically trigger rekeying across dozens of Medeco Biaxial cylinders. We completed a six-hour job at 1501 10th Ave E - two dozen deadbolts, each disassembled, repinned with new OEM components, master and all units changed out. Patented key control means no shortcuts.
- Worn M3 plug retainers in decades-old mortise locks. Capitol Hill and Central District apartment buildings with original mortise hardware often have Medeco M3 cylinders installed in the 1990s or 2000s. The plug retainer - the small clip holding the cylinder core in place - fatigues after twenty years of daily use. We replace with OEM retainers and inspect for collateral wear.
- ADU conversion keyway isolation. Seattle’s 2019 ADU ordinance created sustained demand for separate Medeco keyways on garage and basement conversions. We regularly install Medeco deadbolts with distinct keyways in Wallingford and Columbia City, ensuring the accessory unit and main house maintain independent access control.
Medeco Service in Seattle: What Local Conditions Mean for Your Equipment
Seattle’s 2019 ADU ordinance led to a boom in basement and garage conversions, many of which require Medeco deadbolts with separate keyways to isolate the accessory unit from the main house - a niche installation we handle regularly in neighborhoods like Wallingford and Columbia City. But the ordinance also created a secondary effect few homeowners anticipate: these converted spaces often use exterior-grade Medeco hardware on interior doors that were never meant to carry that load, or they place Medeco deadbolts on outbuilding doors that face directly into Seattle’s prevailing southwesterly rains. The moisture exposure is worse than the original designer planned for. We’ve learned to spec Medeco MTL cylinders with additional weatherization for these applications, or to recommend protected strike configurations that keep water from pooling in the keyway. A Medeco installed without accounting for Seattle’s specific moisture patterns will fail faster here than in Spokane or east of the Cascades - not because the lock is deficient, but because the installation context demands more foresight than a catalog drawing provides.
Medeco Models & Products We Service in Seattle
We work on the full Medeco product line: Biaxial cylinders (the classic angled-pin design), M3 KeyMark with its slider system, Maxum residential deadbolts, and MTL (Micro Torque Lock) commercial cylinders, making us a versatile Commercial Locksmith in Seattle as well. Our Seattle van stocks OEM pins, springs, sidebars, and plug retainers for all four families - most jobs complete without ordering parts.
Our stance on parts is straightforward: genuine Medeco OEM only for replacements. Aftermarket components void the patented key control that makes a Medeco worth installing in the first place. That said, Medeco cylinders are rebuildable. We often reline or repin on-site rather than replace the full hardware, which saves money when the shell and bolt are sound. We’ll tell you honestly which path makes sense after we see it.
We also handle Medeco sales & service for new installations, master key system design, and rekeying after tenant or personnel changes. If you’re unsure which Medeco family fits your door prep, we bring samples to the estimate.
Medeco Service Pricing in Seattle
Medeco work costs more than standard lock service because the parts are patented, the pinning requires specialized tooling, and the tolerances are tighter. Here’s what Seattle homeowners typically see:
- Medeco rekey (single cylinder): $180-$260
- Medeco cylinder rebuild / repin with OEM parts: $220-$340
- Medeco deadbolt replacement / new install: $320-$450
- Master key system rekey (multi-cylinder): $180-$260 per cylinder, with volume pricing for full buildings
- Strike plate adjustment or seasonal alignment service: $89-$150 when bundled with other work
What drives cost: cylinder accessibility (mortise hardware takes longer than standard bored prep), parts needed (OEM pins versus full plug replacement), and whether we’re working from a functioning key or decoding from scratch. Every estimate is free, and we quote flat price on the phone before dispatching. Seniors and veterans receive a permanent 5% discount. Call (888) 545-8474 for your exact figure - estimates cost nothing.

FAQs - Medeco Locksmith in Seattle
No. Medeco’s patented keyway and angled-pin design are physically incompatible with Schlage key blanks. We can, however, install a separate Schlage deadbolt on a different door if you want one key for daily use and Medeco security on a primary entry. Call (888) 545-8474 and we’ll walk through your door layout.
Seattle’s autumn moisture swells wood door frames, pushing the Medeco bolt against the strike plate with enough force to bind the mechanism. The lock itself is likely fine - the frame has moved. We adjust strike alignment and check bolt throw; if you’ve been forcing it, we also inspect for stripped bolt edges. Seasonal adjustment is a routine Seattle service call. Call (888) 545-8474 before the binding damages the cylinder.
Usually not. We can decode the lock and generate a new working key, then rekey to a fresh combination so the lost key no longer operates it. Replacement only makes sense if the cylinder itself is damaged or obsolete. The job takes 45-90 minutes on-site with our Medeco-specific decoding tools. Call (888) 545-8474 for a flat quote - no truck roll until you know the price.
Yes. Seattle’s ADU ordinance created ongoing demand for separate keyways on converted basements and garages. We install Medeco deadbolts with isolated keying in Wallingford, Columbia City, and across the city, ensuring your tenant or family member has independent access without compromising your main house security. We handle the door prep, strike installation, and key control documentation. Call (888) 545-8474 to schedule a free estimate.
Medeco padlocks use the same precision brass pins and sidebar springs as their door cylinders, and Seattle’s persistent moisture corrodes these components faster than in drier climates. Exterior padlocks on boat sheds, storage units, and ADU gates are particularly vulnerable. We recommend annual cylinder cleaning or specifying stainless-steel-body Medeco padlocks for exposed applications. If yours is already binding, we disassemble, clean, and repin with OEM parts on-site.
