Medeco Locksmith in Decatur, GA | Novak Lock & Security Atlanta
Independent Medeco service across Decatur typically runs $180-$420 depending on whether you need a rekey, cylinder swap, or full deadbolt installation, and most calls are completed same-day. What separates our Medeco work here is Decatur itself: this city’s pre-WWII craftsman bungalows with original mortise boxes and its brutal summer humidity create failure patterns you won’t see in newer suburbs. We stock OEM Medeco cylinders and restricted key blanks for the Maxum, M3, and M4 lines, and we quote every job in writing before dispatching. Call (470) 944-6813 for a firm price.
Why Decatur Residents Choose Us for Medeco Service
Daniel Novak picked up the fundamentals at Los Angeles Trade-Technical College, then spent the better part of two decades working locks and commercial keyways across the country before building Novak Lock & Security in 2002. His crew has served Atlanta for years, from rekeying row houses in Inman Park to swapping Grade 1 hardware near Midtown. The name on the van is the warranty.
We are not a Medeco-authorized dealer. That matters for Decatur homeowners because manufacturer-authorized channels often restrict part sourcing, keyway customization, and service options for older Medeco models. As an independent locksmith, we source OEM Medeco cylinders, keys, and wear parts directly, and when Medeco discontinues a line, we match high-quality aftermarket replacements to the lock’s tolerances without waiting on factory approval.
Every Novak technician is background-checked and uniformed, and every visit produces a documented photo record left with the customer. Calls are answered by a live person 24/7, and every price is quoted in writing before anyone turns a cylinder. Haven Standard Clause 1: the price on the phone is the price on the invoice.
Common Medeco Locksmith Problems We Solve in Decatur

- Pin-tumbler wear and keyway contamination from humid summers. Decatur’s humidity routinely pushes 80% for weeks, and airborne pollen and dust settle inside Medeco’s precision pin chambers. The result is sticky operation and keys that won’t turn smoothly. Homeowners often call reporting a “broken lock” when the hardware is structurally sound. We disassemble the cylinder, clean the chambers, and re-lubricate with Medeco-compatible compounds rather than replacing good hardware.
- Restricted key duplication failures. Medeco’s M3 and M4 restricted keyways require the owner’s duplication card for copies. We regularly field panicked calls from Oakhurst and Winnona Park where the original Medeco key is lost and no card exists. Without that card, big-box stores and generic locksmiths are legally blocked from cutting replacements. We can rekey the lock to a new keyway and issue fresh restricted keys, or in some cases source card-verified duplicates through our independent supply channels.
- Deadbolt throw binding from seasonal frame swelling. Decatur’s old-growth pine and fir door frames absorb moisture and expand nearly an eighth of an inch in peak summer. A Medeco Maxum deadbolt that throws smoothly in March binds against its strike plate by July. The lock itself is fine. We adjust strike plates, plane door edges, and realign hardware rather than selling unnecessary replacements.
- Electronic Medeco module faults. Medeco eCylinder and electronic access modules in mixed-use buildings near Decatur’s downtown suffer battery corrosion and firmware lock-ups after repeated heat-humidity cycles. The mechanical cylinder often still works fine. We replace the electronic module with OEM or compatible parts and reprogram credentials, saving the cost of a full lock replacement.
- Mortise lock adaptation for historic homes. Decatur’s preservation-minded homeowners in neighborhoods like Oakhurst and Winnona Park want Medeco-grade security without destroying original mortise boxes that have operated for 90-plus years. We retrofit Medeco cylinders into existing mortise hardware, machine adapters where needed, and preserve the original door prep.
Medeco Service in Decatur: What Local Conditions Mean for Your Equipment
Decatur’s historic preservation culture shapes Medeco work here in ways that simply do not apply in surrounding DeKalb County. In Oakhurst and Winnona Park, homeowners routinely call us to adapt Medeco high-security retrofits to original mortise lock boxes rather than cutting new bore holes for standard deadbolts. This skill is irrelevant in the newer subdivisions where 2-1/8 inch door prep is already standard. Our tech was called to a 1928 craftsman bungalow on South McDonough Street where the owner’s Medeco Maxum deadbolt would not throw fully during July’s humidity. The original fir door frame had swelled nearly an eighth of an inch, binding the bolt against the strike plate. We adjusted the strike plate and planed the door edge rather than replacing the Medeco cylinder, and the lock operated smoothly without any hardware replacement. That call cost the owner $145. A less experienced technician might have quoted $380 for a full deadbolt replacement the lock did not need.

FAQs - Medeco Locksmith in Decatur
No. Medeco’s restricted keyway system legally blocks duplication without the owner’s card. If your card is lost, we rekey the lock to a new keyway and issue fresh restricted keys. Call (470) 944-6813 for a firm quote; estimates are free.
Usually not. In Decatur, seasonal frame swelling from humidity causes more Medeco “failures” than actual hardware defects. We diagnose whether the bolt, the strike plate, or the door frame is the problem, and we adjust rather than replace when the lock body is sound. Call (470) 944-6813 and we’ll walk through the symptoms before dispatching.
Yes. We retrofit Medeco cylinders into existing mortise boxes and machine adapters where the original keyway differs from modern specs. The original door prep stays intact. Decatur service area coverage includes all historic neighborhoods.
Yes. We rekey Medeco cylinders to new pin combinations and issue fresh restricted keys. The old key becomes inoperable. Agnes Scott’s late-August move-in season keeps us busy with exactly this request from landlords on East College Avenue and South McDonough Street. Call (470) 944-6813 to schedule before the rush.
Yes. We replace corroded battery contacts, swap failed modules, and reprogram credentials for Medeco eCylinder and electronic access systems. The mechanical cylinder usually survives; the electronics are what fail after heat-humidity cycling.
