Medeco Lock Installation & Rekey in Marietta: What to Know First
We provide independent Medeco lock installation and rekey services in Marietta, with most residential jobs completed same-day and commercial master-key projects scheduled within 48 hours. Rekeying a Medeco cylinder typically runs $45-$85 per core, and full deadbolt or mortise installation ranges $280-$520 depending on door prep and hardware grade - every price quoted in writing before we dispatch, per Haven Standard Clause 1. This page is for Medeco owners in Marietta who need a cylinder rekeyed, a new high-security deadbolt installed, or a failed Medeco lock diagnosed without the runaround of a call center that can’t name the part. Call (762) 252-5919; a live person answers.
How Medeco Products Fail - and How We Fix Them
- Medeco Biaxial and Classic cylinders with sticky or grinding key turns. The sidebar slots in these older series collect fine grit from Marietta’s pollen-heavy springs and the red clay dust that tracks in on boots. We disassemble the cylinder, ultrasonic-clean the sidebar and pin chambers, then rekey to a new key code or master key system rather than selling you a cylinder you don’t need.
- Medeco M3 deadbolts with key extraction failures. The angled cuts on M3 keys create lateral torque on the plug face; after 8-12 years of daily use, the plug bore elongates and keys hang up. We measure the bore wear with a plug gauge - if it’s within 0.003″, we rekey with a new sidebar and springs; if it’s beyond spec, we quote an OEM M3 cylinder replacement, never a rekey on a worn housing.
- Medeco X4 residential knobs and levers with latch misalignment. The X4’s standard-duty latch mechanism wasn’t designed for the seasonal humidity swell we see in Marietta’s older frame homes near Whitlock Avenue and the historic district. The door shifts 1/8″ to 3/16″ summer to winter, and the latch binds. We diagnose the frame condition, then either reposition the strike with a mortise box or upgrade to a commercial-grade Medeco latch set - we name which before we cut metal.
- Medeco Logic (CLIQ) electronic cylinders with intermittent communication faults. The battery sled contacts oxidize in Georgia’s high humidity, and the programming port can corrode if the cylinder faces a sprinkler head or gutter drip. We clean the contact array, test draw current with a multimeter, and rekey the mechanical core while the electronics are on the bench - two procedures, one trip.
- Medeco KeyMark interchangeable cores (IC) with control key slippage. The control lug on KeyMark Best-format cores wears where it engages the retaining clip; a sloppy removal risks dropping the core into the door cavity. We inspect the lug engagement depth with a depth gauge, replace the control key if the shoulder’s worn, and rekey the core only after confirming the housing is serviceable - not every tech carries the IC removal tools for this, and forcing it destroys the core.
Our Medeco Lock Installation & Rekey Process
- 1
Call intake with part identification. The dispatcher asks for the Medeco series name, keyway stamp, and what’s failing. If you don’t know, we walk you through reading the cylinder face or key head - no guesswork on what parts to load.
- 2
On-site diagnostic with documentation. The technician photographs the installed hardware, identifies the exact cylinder by part number, and tests function before disassembly. You get a copy of the photo record at job completion.
- 3
Written scope and firm price. We specify OEM Medeco parts versus quality aftermarket equivalents where available, note warranty implications of each, and quote the full price. Haven Standard Clause 1: the price on the phone or on the written scope is the price on the invoice. The technician cannot change it.
- 4
Rekey or installation with bench verification. Cylinder work is done on a portable pinning kit, not over your threshold. New keys are cut on a Medeco-compatible duplicator and tested for shear-line alignment before the cylinder goes back in the door.
- 5
Final function test and key count. We cycle the lock 20 times, verify the deadbolt throw clears the jamb without binding, and count keys against the work order. You sign for the key count; we leave one key tagged for your records.
- 6
365-Day Done Right Promise activation. The warranty is printed on the invoice with a direct callback number. If the key hangs, the bolt drags, or the cylinder loosens, we return and make it right.

Why Marietta Homeowners Call Novak Lock & Security Marietta for Medeco Work
We’ve rekeyed and installed Medeco hardware in Marietta since the mid-2000s, back when the Biaxial was the standard high-security cylinder and the M3 was new. Daniel Novak, our owner, came up through a formal locksmithing program and handles the diagnostic work personally on complex jobs - he identifies the cylinder, pin stack, or actuator at fault before quoting, not after. Our technicians carry Medeco pinning kits, key blanks, and the specific sidebar tools these cylinders require; we’re not ordering parts after we show up. If your Medeco hardware is beyond service or you need a faster solution, we also install and rekey Schlage and Kwikset lines, quoted the same way. The 365-Day Done Right Promise applies to every lock, every brand. The name on the invoice is the same name on the van. That’s the whole argument.
FAQs
No, rekeying by a competent locksmith does not void Medeco’s limited lifetime warranty on mechanical cylinders, provided no aftermarket parts are substituted for OEM components. We use Medeco factory pins, springs, and sidebars on warranty-sensitive jobs and note the part numbers on your invoice for your records. Call (762) 252-5919 if you need warranty documentation assistance.
Most residential Medeco rekeys are completed same-day, often within two to four hours of your call. Commercial master-key projects or multiple-cylinder jobs in properties near Barrett Parkway or the Town Center area are typically scheduled within 24-48 hours. Call (762) 252-5919 for today’s availability - a live person answers.
Repair and rekey is economical when the plug bore is within specification, the sidebar track isn’t wallowed, and the keyway hasn’t been damaged by forced entry attempts. We measure these three points during diagnostic and tell you which side of the line your cylinder falls on. Replacement makes sense when the housing is worn or you need to upgrade from Biaxial to M3 or X4 security levels. The written quote shows both paths when both are viable.
We stock Medeco key blanks, pinning kits, and common cylinders for same-day residential work. Specialty items - Logic batteries, restricted keyway cylinders, or large-format interchangeable cores - may require 24-48 hour ordering. We tell you which category your job falls into during the initial call, not when the technician is standing at your door.
Yes. Haven Standard Clause 1 prohibits our technicians from changing the quoted price at your door. The only exception is if you add scope after quote - for example, deciding to rekey three additional cylinders once we’re on site. Even then, the addition is quoted in writing before work proceeds. Call (762) 252-5919 for a firm, free estimate.
