Medeco Locksmith in Portland, NY | Novak Lock & Security
We provide independent Medeco service across Portland, from rekeying a single Biaxial deadbolt to building a master-key system for a house with a backyard ADU. The thing that makes our Medeco work here different is simple: we service the cylinder in place, accounting for how Portland’s rainy season swells old fir door frames and binds mechanically sound bolts. If you need a Medeco lock rekeyed, repaired, or integrated, call our Portland Emergency Locksmith line at (331) 310-8471 for a written price before anyone is dispatched.
Novak Lock & Security has worked on Medeco 3, Biaxial, and M3 systems in Portland homes for over a decade. We are not a Medeco factory-authorized dealer and we don’t pretend to be. What we are is experienced, independent, and stocked with genuine Medeco pin kits and springs for same-day work. Daniel Novak, our owner, learned the trade in New York’s five boroughs and brings that straight-answer discipline to every Portland job. The name on the van is the same name on the invoice.
Why Portland Residents Choose Us for Medeco Service
Most locksmiths in Portland will swap a Medeco cylinder for a generic Schlage or Kwikset because they don’t carry the pin kits or understand the key control. We don’t do that. A Medeco cylinder is a deliberately engineered mechanism, the tumblers rotated to precise angles, the sidebar requiring exact alignment. We carry genuine Medeco tumblers, springs, and pins for all three generations, and we rebuild or repin whenever the cylinder body is sound. Replacement is a last resort, not a first upsell.
In Portland specifically, that matters because so much of the close-in eastside housing stock runs on original mortise hardware. Homeowners in Irvington, Richmond, and Sellwood don’t want a century-old Corbin lockset ripped out for a modern cylindrical deadbolt. They want the Medeco cylinder serviced inside that original body, or a discreet retrofit that preserves the escutcheon. We do exactly that, and we photograph everything before and after so there’s a documented record of what was touched. Daniel has spent two decades working doors and deadbolts in old buildings. That’s the experience Portland’s pre-war bungalows actually need.
Common Medeco Locksmith Problems We Solve in Portland

- Deadbolt won’t throw, though the key turns fine. In Portland’s October-to-May rainy season, old-growth fir door frames absorb moisture and swell. The Medeco cylinder is mechanically fine, but the bolt rubs against a warped or misaligned strike plate. We mortise the pocket deeper rather than sell you a new lock.
- Sticky, gritty key feel after autumn storms. Fine silt and pine needle debris from Portland’s storm season works into Medeco 3 plug springs. The fix is ultrasonic cleaning of the cylinder and fresh lubricant, not a repin and not a replacement.
- Key turns but bolt doesn’t throw in older Biaxial retrofits. Worn sidebar springs fail to retract fully on 1980s and 90s Biaxial installations around Portland. It presents like a broken cylinder; it’s actually a spring replacement. We diagnose by feel, not by guess, and we tell you which one it is before quoting.
- Frozen tumblers in detached garage or ADU M3 cylinders. Portland’s freeze-thaw cycles below 28°F collect moisture inside the plug of cylinders on outbuildings. The lock seizes. We de-ice and re-lubricate before any rekeying work begins, an order of operations that prevents damage.
- Master-key integration after an ADU build. Portland’s relaxed ADU rules mean a backyard cottage with its own Medeco deadbolt must be tied into the main house key without compromising the restricted keyway. We build small master-key hierarchies that respect Medeco’s key-control logic.
Medeco Service in Portland: What Local Conditions Mean for Your Equipment
Portland’s 2021 ADU reforms did more than add housing stock; they created a specific locksmithing problem that no national Medeco documentation addresses. When a homeowner adds a backyard cottage to a single-family lot, that structure gets its own independently keyed Medeco deadbolt, a cylinder with a restricted keyway and its own key-control card. The owner now has two high-security locks on one property that should, ideally, open with one key. Building that master-key hierarchy without breaking the restricted keyway means cutting a new Medeco master key to spec, pinning the second cylinder to accept both its own key and the master, and documenting every step so the key-control trail stays intact. In Irvington or Richmond, where the main house is often a 1920s bungalow with an original mortise lockset, we’re doing that integration inside hardware that predates Medeco by half a century. That is not a scenario a technician in Beaverton or Lake Oswego sees with anything like this frequency.
Medeco Models & Products We Service in Portland

We work on the full span of Medeco hardware found in Portland residential and light commercial settings. Medeco 3, the classic pin-tumbler high-security cylinder, shows up most often in older bungalow retrofits and small apartment buildings. Medeco Biaxial, with its rotating-tumbler upgrade, is common in 1980s and 90s commercial installs across Portland’s inner eastside. Medeco M3 appears on newer builds and ADUs, with its sidebar and slider providing the advanced key control Portland property owners increasingly ask for when adding a rental unit. Medeco KeyMark restricted keyway cylinders serve multi-unit buildings and small businesses that need controlled key duplication.
On parts, our stance is straightforward. We stock genuine Medeco pin kits, tumblers, and springs for all three generations. Aftermarket blanks get used only for cosmetic or non-critical keys. Given Medeco’s key-control licensing, we rebuild or repin whenever the original cylinder body is sound, and we only recommend replacement when the plug or sidebar is physically worn beyond tolerance. That keeps your Medeco investment alive and keeps the key-control chain intact.
Medeco Service Pricing in Portland
Medeco work costs more than standard lock work because the parts cost more and the labor requires more care. Here’s what you can expect, written in plain dollars.

What drives cost here is the cylinder generation, the condition of the original hardware, and whether we’re working inside a pre-war mortise lockset that needs careful disassembly. Every estimate is free and in writing before work starts. Haven Standard Clause 1: the price on the phone is the price on the invoice. Call (331) 310-8471 and we’ll give you a firm number.

FAQs - Medeco Locksmith in Portland
Your cylinder is fine. What’s happening is that Portland’s rainy season has swollen the old-growth fir door frame, and the bolt is now binding against the strike plate rather than sliding cleanly into the pocket. We see this every November through April in pre-war bungalows across Richmond, Sellwood, and Irvington. The fix is mortising the pocket deeper, and often adjusting the plate, not replacing the Medeco. Call us for a diagnostic; the service call is $49, applied toward any repair you approve.
Yes. The original key-control card makes the process faster and preserves the formal key-control chain, but it’s not a requirement. We can decode the existing cylinder, cut new keys, and rekey to a fresh bitting without the card. We’ll document the new key information and hand you a record when we leave. Call (331) 310-8471 and we’ll quote the rekey over the phone.
No. We don’t rip out original mortise locksets in Portland’s historic character districts. A proper Medeco retrofit on a pre-war bungalow means either servicing the original mortise cylinder in place or installing a Medeco cylinder in a discreet rim or deadbolt that preserves the original escutcheon and hardware. Our techs have done this on Craftsman bungalows across the eastside, and the original Corbin or Yale hardware stays where it belongs. You get Medeco key control, the house keeps its character.
No. That grit is debris, fine silt and pine needle dust from Portland’s autumn wind and rain working into the plug springs. It’s a condition, not a defect. We disassemble the cylinder, run it through an ultrasonic cleaner, lubricate the pins and sidebar, and reassemble. The cylinder feels new again. $35-$60 per cylinder. Call (331) 310-8471 for a firm quote.
Yes, and this is one of the most common requests we field in Portland since the ADU rules changed. We pin the ADU cylinder to accept both its own key and a new master key, cut the master to Medeco’s spec, and document the new key hierarchy so your key control stays clean. Expect $150-$300 per cylinder depending on generation and existing hardware. Call us for a written quote before anyone is dispatched.
