Medeco Residential Locksmith in Ashburn: What to Know First
We provide independent Medeco residential locksmith service in Ashburn, typically same-day for lockouts and scheduled within 24-48 hours for installations or rekeys. Most Medeco jobs run $240-$580 depending on the series and whether we’re working with existing hardware or replacing a failed cylinder. The price we quote on the phone is the price on the invoice - Haven Standard Clause 1, in force since 2002.
This page is for Ashburn homeowners who already have Medeco deadbolts, rim cylinders, or padlocks and need service that preserves the security grade they paid for. If you’re locked out in Broadlands, rekeying after a move in Brambleton, or replacing a seized Maxum deadbolt in One Loudoun, we stock the right pins, cams, and key blanks in the van. Call (571) 410-8874 for a written estimate.
How Medeco Products Fail - and How We Fix Them
- Maxum 11*503 / 11*505 deadbolts with sticky or seized thumbturns. The cast zinc housing expands slightly in Ashburn’s summer humidity cycles, and the internal cam tolerances tighten. We see this most in south-facing doors on Brambleton townhomes. We disassemble, clean the cam track, and replace the thumbturn assembly with OEM-spec parts rather than lubricating and leaving - grease attracts dust and the seizure returns in six months.
- Medeco3 (M3) cylinders with keys that catch or require jiggling. The sidebar and slider system is precise to .001 inch; wear or a single bent pin creates intermittent misalignment. We pin-gauge the chamber, replace individual bottom pins if they’re within spec, or swap the full cylinder if the sidebar slot is wallowed. We do not file or force - that voids the UL 437 listing.
- Original Medeco Biaxial cylinders in pre-2015 Ashburn homes. These use angled cuts that wear keyways asymmetrically. After 15+ years, the keyway itself distorts and even new keys wobble. We measure keyway width with a bore gauge; if it’s over .005 inch out of spec, we recommend a cylinder replacement rather than continued rekeying - a rekey on a worn keyway fails again in 18 months.
- Medeco rim cylinders on garage-entry doors with corroded tailpieces. Ashburn’s freeze-thaw and road salt tracked in from Route 7 accelerate steel tailpiece rust. The cylinder turns but the latch doesn’t retract. We replace with stainless tailpieces where available, or brass on jobs where the door prep won’t accept the larger stainless profile.
- Medeco X4 (now discontinued) with keys that won’t retract. The X4 used a different keyway geometry than current lines; blanks are increasingly scarce. We stock limited X4 blanks and can often source them through our wholesale channels, but we flag this upfront - if the cylinder is failing and blanks are exhausted, conversion to Medeco3 or Maxum is the honest recommendation.
Our Medeco Residential Locksmith Process

- 1
Call intake. We ask for the series name (printed on the key bow or cylinder face), the symptom, and door location. This determines what we load in the van - a Maxum rekey needs different pinning kits than an M3.
- 2
On-site diagnosis. Technician inspects the cylinder, tests key operation, and checks door alignment. Misaligned strike plates cause more Medeco failures than owners realize - the bolt binds, and force on the key damages the sidebar.
- 3
Parts decision. We use OEM Medeco pins, springs, and cams for all warranty-sensitive work. For out-of-warranty cylinders where the owner wants cost control, we may offer quality aftermarket equivalents - documented in writing, with the trade-off explained.
- 4
Repair or replacement. Rekeys are done in the van or at our bench; installations include new strike reinforcement if the existing prep is undersized. Every cylinder is hand-cycled 20 times before the key is handed over.
- 5
Documentation. Photo record of the work area, the installed hardware, and the key codes (stored securely). Written invoice with itemized labor, parts, and the 365-Day Done Right Promise printed at the bottom.
- 6
Key verification. We cut and test all keys on-site; you leave with working copies, not promises to mail them later.

Why Ashburn Homeowners Call Novak Lock & Security Ashburn for Medeco Work

We are an independent Medeco service provider - not affiliated with or authorized by Medeco - which means we work for the homeowner, not the manufacturer. Daniel Novak brought this operation to Ashburn after years in the field, and the name on the invoice is the same name on the van.
Our technicians carry Medeco pinning kits, key blanks, and replacement cylinders as standard stock. When a Medeco line is discontinued or backordered, we have the cross-reference knowledge to source compatible hardware or recommend a clean upgrade path. We also service Schlage and Kwikset for homes with mixed hardware - one visit, one invoice, one photo record.
The 365-Day Done Right Promise applies to every Medeco job. Haven Standard Clause 1 applies to every call. Background-checked, uniformed technicians. Live answer, 24/7.
FAQs
Rekeying by a qualified locksmith does not void Medeco’s limited lifetime warranty on mechanical defects, provided OEM parts are used and the cylinder is not modified. We document parts provenance on every invoice for this reason. Call (571) 410-8874 if you need warranty documentation for a claim.
We stock common Medeco3 and Maxum cylinders, pins, and key blanks in our Ashburn van inventory. Obsolete lines like the X4 or certain Biaxial keyways may require 24-72 hours through our wholesale channels - we’ll tell you during the call, not at your door.
Replace if the keyway is worn beyond .005 inch tolerance, if the series is discontinued and blanks are scarce, or if repair costs exceed 60% of replacement. Repair if the cylinder body is sound and the failure is isolated to pins or springs. We measure and report, then quote both options in writing.
Lockouts: typically 25-45 minutes depending on traffic on Route 7 or the Greenway. Scheduled work: usually next business day, sometimes same day if the call comes in before 10 a.m. and the parts are in stock.
Haven Standard Clause 1: the price on the phone is the price on the invoice. The technician is contractually prohibited from changing it. This rule has been in place since 2002. The only exception is if you add scope during the visit - and even then, we stop and re-quote in writing before continuing.
