Lodestar Locksmith provides independent Medeco service across Mercer Island and Eastgate Medeco service, from Maxum deadbolts to M3 and M4 high-security cylinders and KeyMark systems. What makes our Medeco work here different is simple: we know how this island’s salt air, 1960s door prep, and I-90-only access affect your hardware. We’re not authorized by Medeco and we say so plainly, but we know their cylinders at the sidebar level. Call (855) 382-0943 for a free estimate.
Why Mercer Island Residents Choose Us for Medeco Service
Norm Eckley, our owner, cut his teeth on commercial Medeco hardware across Pierce County and Medeco in Newcastle before Lodestar ever took its first Mercer Island call. He grew up in Tacoma’s Hilltop neighborhood, where half the deadbolts on his block hadn’t turned right since the Carter administration, so he learned early that a lock isn’t just a lock: it’s the door, the frame, the strike, and the key control behind it. When a Mercer Island homeowner calls about a Medeco cylinder that won’t release its key on a waterfront entry, we know the salt corrosion pattern before we arrive. That’s the difference between a shop that swaps cylinders and one that fixes the whole assembly.
We stock genuine Medeco OEM cylinders, sidebar pins, and keys for restricted and patented keyways. Aftermarket blanks break the key-control chain Medeco owners pay for, so we don’t use them. And because Medeco work on this island often runs on a move-in or a lost-key deadline, we batch our Medeco sales & service route along Island Crest Way and West Mercer Way to cut bridge traffic out of the equation where it counts.
Rekeying a Medeco cylinder: new security without new hardware. Half our calls on the island end in a re-pin, not a replacement, because the cylinder itself is still sound. We’ll tell you straight when a Maxum is worth rebuilding and when it’s done. Call (855) 382-0943 and we’ll give you that answer before a van rolls.

Common Medeco Locksmith Problems We Solve in Mercer Island
- Salt-corroded cylinders on waterfront entries. Lake Washington and Puget Sound air pits exterior Medeco plugs and cams. A deadbolt that turned freely in spring can seize by the first wet winter on an unsheltered east-facing door. We rebuild and re-lubricate before recommending replacement: a corrosion-bound Maxum or M3 doesn’t always need to be thrown away.
- Dragging bolts in swollen 1960s and 70s door preps. Medeco Maxum and M3 installations on original Mercer Island doors often sit in swollen wood stiles and worn strike mortises. The bolt drags, the cylinder binds, and the lock itself is fine. The door is the problem. We re-cut the strike, reinforce the jamb, and free the cylinder.
- No key-control card after a move-in or sale. Restricted-keyway Medeco cylinders on island properties frequently arrive with no control card and no record of who holds copies. A re-pin to a fresh restricted keyway restores real key control, and we issue new cards on site.
- Strike tears out while the sidebar holds. Hardened Medeco deadbolts defeat picks, so forced entry goes after the frame instead. On older hollow-core and thin-jamb doors, the strike plate rips out and the cylinder survives. Door reinforcement fixes what the lock can’t.
- Dead batteries on Medeco eCyl electronic cylinders. Second homes and vacation properties on the island strand their owners at the gate on the first seasonal visit. Corroded contacts and dead eCyl batteries are a spring and fall constant here. We replace, re-program, and get you through the gate.
Medeco Service in Mercer Island: What Local Conditions Mean for Your Equipment
Mercer Island has essentially no commercial locksmith storefront serving its residential stretches, and the only road on or off the island is I-90 over the floating bridge. That means any Medeco restricted-key blank or cylinder we don’t have on the van is a bridge round-trip. So we schedule island Medeco work in batches around the Island Crest Way and West Mercer Way corridors, because those are the only practical north-south routes and bridge traffic backs up fast. What that means for your equipment: when a waterfront Medeco Maxum seizes in January, the fix isn’t just the cylinder; it’s getting the right sidebar pins and a fresh restricted blank onto the island without two hours of I-90 standstill. We arrange our whole call flow around that constraint. A shop in Seattle or Medeco in Bellevue doesn’t think that way, because they don’t have to.
Medeco Models & Products We Service in Mercer Island
We service Medeco Maxum deadbolts, KeyMark and KeyMark SL cylinders, M3 and M4 high-security cylinders in original and patented-keyway versions, and Medeco eCyl electronic cylinders. For restricted or patented keyway work, we use only genuine Medeco OEM cylinders, sidebar pins, and keys so your key control stays valid and the manufacturer’s keyway protections aren’t broken by aftermarket blanks. On worn but structurally sound cylinders we rebuild and re-lubricate before recommending replacement, because a Maxum or M3 that’s just corrosion-bound doesn’t need to be thrown away. We carry the most common Medeco parts on the van for same-day Mercer Island turnaround, and we know exactly what a bridge run costs when we don’t have it.
Medeco Service Pricing in Mercer Island
Medeco work on Mercer Island is priced by the job, not by a teaser rate. A straightforward rekey of a restricted cylinder runs lower than a full replacement; a Maxum re-pin with new control cards sits in the middle; an eCyl replacement and programming lands higher. The variables are the cylinder’s condition, whether key control needs to be rebuilt, and whether the door prep needs reinforcement. Your free estimate includes a phone breakdown of what we’ll do and what it costs before anyone is dispatched, and that’s the price on the invoice. No call-out surcharge added on arrival. Call (855) 382-0943 for an exact quote on your Medeco hardware.

FAQs – Medeco Locksmith in Mercer Island
Yes, for keyways where you hold valid key-control cards. For restricted Medeco keyways, duplication requires proof you’re authorized to order blanks, and we verify that before we cut anything. If the cards are lost or the previous owner kept copies, we re-pin to a fresh restricted keyway and issue new cards. Call (855) 382-0943 and we’ll check your keyway before you drive anywhere.
Salt-laden air off Lake Washington corrodes the plug and cam faster on the weather side. The same lock on the protected side of the house doesn’t see that exposure. We see this pattern on Mercer Island waterfront entries every winter: the fix is a clean, re-lubricate, and often a cam replacement, not a new deadbolt. Call (855) 382-0943 and we’ll assess it on site.
Usually not. The original door prep on mid-century island homes swells with winter moisture and the strike mortise wears, so the bolt binds against the jamb even when the Maxum cylinder is fine. We free the bolt path, re-cut the strike, and reinforce the jamb before we touch the cylinder, because throwing out a sound Maxum wastes your money. Call (855) 382-0943 for an exact diagnosis.
Yes. Mercer Island’s only road access is I-90 over the floating bridge, so our scheduling treats every island Medeco job as a bridge crossing. We batch calls along Island Crest Way and West Mercer Way to avoid midday bridge backups and keep part shortages from becoming a two-hour round trip. It’s why we carry the most common Medeco parts on the van.
Yes, that’s a re-pin across all cylinders to a single restricted keyway, and it’s regular work on Mercer Island where gates, pool houses, and outbuildings multiply the cylinders. We’ll need the control cards for the existing keyway, or we’ll re-pin from scratch and issue fresh cards. Call (855) 382-0943 and we’ll scope it before you commit.
