Medeco Residential Locksmith in Marietta: What to Know First
We provide independent Medeco residential locksmith service in Marietta, typically same-day for standard jobs and within the hour for lockouts. A Medeco deadbolt rekey runs $45-$75 per cylinder; a full high-security lock change with installation runs $280-$420, quoted in writing before we dispatch. This page is for homeowners in Marietta who already have Medeco hardware and need service, replacement, or an upgrade path that preserves their keying investment. Call (762) 252-5919 for a firm price.
How Medeco Products Fail - and How We Fix Them
- Medeco M3 cylinder keyway binding. The M3’s angled key pins and sidebar tolerances collect fine grit from Marietta’s pollen-heavy springs and dry summer dust. The key starts to catch at 10 and 2 o’clock, then sticks entirely. We strip the cylinder, ultrasonic-clean the pin chambers, lubricate with Medeco-specified graphite, and replace the sidebar springs if they’ve taken a set. Rekey adds $20 per cylinder if you want fresh pinning.
- Medeco Biaxial deadbolt throw misalignment. The Biaxial’s dual-locking mechanism depends on precise cam timing between cylinder and bolt. After 8-12 years in Marietta’s humidity-cycling climate, the cam wears or the mounting screws loosen, and the bolt throws only halfway. We measure cam depth with a depth gauge, reset or replace the cam, and shim the strike plate if the door frame has shifted. OEM cams are available; we stock the common Biaxial variants.
- Medeco Maxum 11*603 latch failure on entry doors. The Maxum’s heavy-duty latch uses a dual-spring retractor that corrodes where Marietta’s afternoon thunderstorms leave moisture in the door edge. The latch sticks retracted or won’t extend fully. We replace the retractor assembly with OEM or a tested aftermarket equivalent, then seal the door edge with a proper weatherstrip. Full assembly replacement runs higher than a simple latch swap, but partial fixes fail again in 18 months.
- Medeco key duplication drift. Medeco keys cut on standard duplicators lose the angled cuts and sidebar grooves that make the lock high-security. We see this in Marietta when owners take Medeco blanks to hardware stores. The copy works poorly or damages the sidebar. We cut factory-spec duplicates on a Framon or Code Machine with Medeco-certified angles, or we order factory-cut keys with card verification if you have the key code card.
- Medeco rim cylinder screw post shear. Rim cylinders on Marietta’s older solid-core doors endure torque from over-tightened mounting screws. The brass post cracks, the cylinder spins, and the key won’t retract the bolt. We extract the broken post, install a steel-threaded insert or replace the cylinder housing, and torque to spec. We also check whether the door thickness has compressed over years, which changes the cylinder projection and causes binding.
Our Medeco Residential Locksmith Process
- 1
Call and key identification. We ask for the key head markings - Medeco, M3, Biaxial, Maxum - and the problem symptom. The dispatcher quotes a firm price range based on the likely scenario. Haven Standard Clause 1: the price on the phone is the price on the invoice.
- 2
On-site diagnostic. The technician identifies the exact model, series, and failure point. For Medeco, this means checking cylinder generation (original, Biaxial, M3, X4), sidebar function, and keyway condition. We photograph the hardware before touching it.
- 3
Parts decision with the customer. OEM Medeco parts carry full warranty but cost more. Quality aftermarket cylinders from GMS or Ilco work in Medeco keyways at lower cost but void any remaining Medeco warranty. We state both options in writing.
- 4
Repair or replacement. We perform the work, test all keys through 50 cycles, and verify sidebar engagement on every rotation. Medeco’s pick resistance depends on that sidebar seating fully.
- 5
Documentation and cleanup. You receive the written invoice, a photo record of the completed work, and the 365-Day Done Right Promise. We leave the work area as found.

Why Marietta Homeowners Call Novak Lock & Security Marietta for Medeco Work
Daniel Novak and our technicians have handled Medeco hardware since the Biaxial era. We carry the pin kits, sidebar tools, and key blanks that most Marietta shops route to Atlanta for. When a Medeco part is obsolete, we know which Schlage or Kwikset upgrade path fits the same door prep without new mortising. The 365-Day Done Right Promise applies to every Medeco job. Calls reach a live person at (762) 252-5919, 24 hours. The name on the invoice is the same name on the van. That’s the whole argument.
FAQs
Does servicing my Medeco lock with Novak void the manufacturer warranty?
Medeco’s warranty covers defects in manufacturing, not service by independent providers. As an independent Medeco service provider, we use OEM parts when warranty preservation matters to you, and we document the part serial numbers. If your lock is under Medeco’s original warranty, we can coordinate with them or you can choose our work with aftermarket parts at lower cost. Call (762) 252-5919 and we’ll check your series and purchase date.
Can you get Medeco parts same-day in Marietta?
We stock common Medeco cylinders, cams, and key blanks for M3 and Maxum lines. Biaxial and X4 parts sometimes require a day from our Atlanta distributor. We tell you before dispatch if your job needs a parts run. Same-day rekeying is almost always possible regardless.
Should I repair my Medeco lock or replace it?
Repair makes sense when the cylinder is sound and the failure is in a replaceable component - sidebar springs, cam, latch retractor. Replace when the cylinder body is cracked, the keyway is worn beyond spec, or you need a security upgrade to the M3 or X4 generation. We assess both paths on-site and quote each in writing.
How do I know the technician is qualified for Medeco?
Every Novak technician is background-checked, uniformed, and trained on high-security pin-tumbler systems including Medeco’s angled-cut and sidebar mechanisms. We leave a documented photo record of every visit. Daniel Novak personally reviews any Medeco job that involves cylinder rebuilding or key-code generation.
Is the phone quote the final price?
Yes. Haven Standard Clause 1 prohibits changing the quoted price at the door. The only exception is if you add work after we arrive, and even then we re-quote in writing before starting. The price on the phone is the price on the invoice.
