Medeco Lock Installation & Rekey in Maryland: What to Know First
We provide independent Medeco lock installation and rekey services across Maryland, typically completing residential jobs same-day or next-day with a flat price quoted before we leave the shop. Most Medeco rekeys run $145-$220; new Medeco deadbolt installations range $280-$450 depending on door prep and the series. This page is for Maryland homeowners who already own Medeco hardware and need it installed correctly, rekeyed after a move or staff change, or repaired without the runaround. Call (844) 314-7347 for a free estimate - a live person answers, including Sunday evenings.
How Medeco Products Fail - and How We Fix Them
- Medeco Maxum deadbolts with sticky key rotation. We see this constantly in Maryland’s humidity, especially in waterfront homes from Annapolis to Kent Island. The sidebar pins absorb atmospheric moisture and the precision-milled keyway gums up with oxidized lubricant. We disassemble, clean with non-residue solvent, repack with Medeco-spec lubricant, and cut a fresh key to factory depths if the original shows wear.
- Medeco Biaxial cylinders with sheared sidebar springs. These older cylinders, still common in Baltimore County rowhomes installed in the 1990s, use a dual-angle pin design that demands exact spring tension. When a spring fatigues, the sidebar drops partially and the key turns halfway before binding hard. We replace with OEM Medeco sidebar springs - aftermarket substitutes are too soft and fail again in eighteen months.
- Medeco M3 cylinders with false-set issues after rekeying. The M3’s slider mechanism interacts with the pin stack in ways that don’t forgive sloppy pinning. A tech who treats it like a standard Schlage will create a lock that feels “almost right” but hangs on certain key withdrawals. We pin to Medeco’s factory spacing chart and test every key position through ten full cycles before we sign off.
- Medeco KeyMark cylinders in commercial settings with worn keyways. KeyMark uses a different keyway geometry than the residential lines, and Maryland property managers often call us when a new key won’t seat fully. The brass keyway itself hasn’t failed - the previous tenant’s keys were poorly duplicated on inaccurate machines, gradually wallowing the entrance. We measure with a keyway gauge and either bush the cylinder or replace it, depending on material loss.
- Medeco deadbolts with misaligned strike plates after door settling. Maryland’s clay soils, particularly in Montgomery County and parts of Howard County, shift seasonally. A Maxum installed perfectly in 2015 now requires shoulder pressure to throw the bolt. We don’t just file the strike - we check door frame square, shim hinges if needed, and relocate the strike so the deadbolt throws freely without binding the mechanism.
Our Medeco Lock Installation & Rekey Process
- 1
Call and quote. You describe the lock, the problem, and your Maryland location. We quote a flat price. No dispatch fee, no “starting at” language.
- 2
Tech arrival and ID. Our technician arrives in a marked Strongbox van, uniformed, and presents identification at your door. Gerald Pittman started this practice twenty years ago after a customer in Catonsville mentioned she’d never felt comfortable with the last locksmith who showed up in an unmarked car.
- 3
Diagnostics with you present. We show you the issue - a worn sidebar, a misaligned strike, a cylinder that needs bushing - and confirm the repair before touching tools.
- 4
Parts decision. OEM Medeco components when they matter for warranty or function; quality aftermarket only when they meet the same spec and save you money without compromise.
- 5
Repair, rekey, or install. We work cleanly, protect your door finish, and test every key position repeatedly.
- 6
Written guarantee and cleanup. We leave you with the 90-Day Done Right Promise in writing, new keys counted and labeled, and no debris. The price matches the quote.

FAQs

For emergency situations, we carry enough inventory to complete most residential rekeys and cylinder replacements on the first visit.
Repair is usually cheaper if the cylinder body and bolt mechanism are sound. A rekey or cylinder refresh runs $145-$295; a full new Maxum installation starts around $280. We assess the lock on site and give you both options with real numbers. Call (844) 314-7347 for a free estimate.
