We service Medeco deadbolts, cylinders, and high-security locks across Four Corners, DC, as an independent locksmith shop, not a factory-authorized dealer. What sets our Medeco work apart here is that we actually understand how Four Corners homes age. If your Medeco key binds in the deadbolt or the sidebar hangs up, call (855) 382-1343 and we’ll diagnose it without the manufacturer-speak.
Why Four Corners Residents Choose Us for Medeco Service
Russell Tapp, who leads our shop, grew up a few miles from Wolf Trap and has spent his whole life in this area. He apprenticed under a seasoned locksmith before going out on his own, and today he’s the person this side of Montgomery County calls when a Medeco Maxum starts fighting the key, whether they need Medeco in Silver Spring or closer in. We’re not a franchise, and we don’t push replacements when a rekey is the honest answer.
Four Corners is a heavily residential pocket off University Boulevard, full of post-war colonials and split-levels with original or first-replacement entry doors. We work on Medeco hardware in those homes every week. We carry OEM Medeco cylinders, pins, and keys for residential work, and our Medeco sales & service knowledge covers everything from Biaxial to M4. One call to (855) 382-1343 gets the right person on the door.

Common Medeco Locksmith Problems We Solve in Four Corners
Medeco locks are well built, but they live in Four Corners houses that move. Here’s what we fix most often:
- Key-control sidebar wear. Medeco’s rotating pin tumblers and sidebar can bind after years of use. When a Four Corners door swells in July, the bolt drags against the strike, and that extra friction wears the cylinder cam. The key starts to feel gritty. We rekey or replace the cylinder with OEM pins before the sidebar fails entirely.
- Strike-plate and bolt misalignment. The freeze-thaw cycle here is relentless. Doors swell humid and shrink dry, and the deadbolt that threw smoothly in September starts scraping in January. We realign the strike plate and adjust the bolt throw, which often saves an expensive cylinder replacement.
- Frozen or stiff pins from humidity. Mid-Atlantic summers push moisture into older Medeco cylinders on exterior doors. Pins stick. Keys resist going in or come out feeling rough. We clean and lubricate the cylinder, then rekey if the pins are too far gone.
- Lost key-control keys. Medeco’s restricted keyway means a lost key isn’t just a trip to the hardware store. We verify ownership, then rekey the cylinder and issue new controlled keys, preserving your key control rather than duplicating into a compromised system.
- Deadbolt replacement on aging doors. Many Four Corners homes still have original builder-grade door slabs. When a Medeco Maxum is paired with a door that’s been patched and shimmed for forty years, the strike plate often won’t hold proper alignment. We replace the lock with a properly fitted unit and realign the strike, not just screw a new cylinder into a bad hole.
Medeco Service in Four Corners: What Local Conditions Mean for Your Equipment
Here’s something specific to Four Corners. Because our ZIP, 20901, straddles the Montgomery County and Prince George’s County line near Medeco service in Hillandale, this is one of those transitions zones where older single-family homes didn’t get the security upgrades that denser, newer developments did. A lot of the original builder-grade hardware off Four Corners itself was never touched. So when a homeowner calls us to rekey one Medeco deadbolt, the visit often turns into replacing two or three worn locksets on the same house, once they see how loose their existing entry hardware actually is. It’s not an upsell. It’s just what decades of freeze-thaw cycles and swelling door slabs do to Schmidt-era locks. The Medeco may be the only lock on that door that’s still doing its job.
That reality shapes our entire approach to Medeco work in Four Corners. We check the strike plate, the door slab, and the cylinder depth before we start turning pins. The goal is a Medeco lock that works in January and July, not just the day we leave.
Medeco Models & Products We Service in Four Corners
We work on the Medeco line most Four Corners homes actually have: Maxum deadbolts, M3 and M4 high-security cylinders, Biaxial locks, and the Uni-Bar deadbolt that some older remodels used. Our approach is repair-first. We use OEM Medeco cylinders and keys whenever available to protect key control and keep your warranty valid. If a Biaxial or Maxum cylinder is worn but serviceable, we rekey it. If the cylinder body or sidebar is cracked, we replace it with a new Medeco cylinder matched to your existing keyway. We keep common residential Medeco components stocked locally, so most Four Corners appointments finish in one visit.
Medeco Service Pricing in Four Corners
What you’ll pay depends on the model and the failure. A Medeco rekey on a Maxum deadbolt in Four Corners typically runs $125 to $220 per cylinder, including new controlled keys. Cylinder replacement for a Biaxial or M3 is usually $180 to $300, and a full Maxum deadbolt installation with door preparation falls between $250 and $450. Humid-season pin cleaning and lubrication is the least expensive fix, often under $100.
There’s no call-out surcharge added when we arrive. The quote you get on the phone, before anyone is dispatched, is the price on your invoice. Call (855) 382-1343 for an exact number, and we’ll walk through your lock over the phone. Estimates are free.

FAQs – Medeco Locksmith in Four Corners
Yes. The key-control card proves authorization for new key cuts through Medeco’s restricted channels, but rekeying the cylinder is different work. We verify you own or control the property, then rekey the existing cylinder with OEM Medeco pins and cut new controlled keys to the new bitting. You don’t need the card for a rekey. Call (855) 382-1343 and we’ll tell you exactly what we need from you.
Because your door is moving. Four Corners sits in the Mid-Atlantic freeze-thaw zone, and wood door slabs from the 1950s through the 1980s shrink noticeably in January. The deadbolt slips out of alignment with the strike plate, and that drag makes the key bind and the thumbturn feel frozen. We realign the strike and retension the lock; it usually solves the winter sticking for good. Get the seasonal fix before the sidebar wears out. Call (855) 382-1343 for an estimate.
We do, and it’s one of the more common upgrades on University Boulevard colonials. The trick with a 1960s door slab is that the door has to be routed and the strike reinforced, or the Medeco hardware sits askew and never throws clean. We install Maxum and M3 cylinders on these doors regularly, with proper door preparation so the lock survives every season. Call (855) 382-1343 and we’ll tell you if your door is a good candidate.
That depends on the keyway. Medeco restricted keys can only be duplicated through authorized channels with the key-control card. We’re an independent service provider, so we don’t duplicate restricted Medeco keys. But we can rekey the cylinder and cut new controlled keys through our OEM parts source, which is often the better security move if keys are unaccounted for. We’ll walk you through the options on the phone at (855) 382-1343.
Biaxial and M3 both use rotating tumblers for pick resistance, but the M3 adds a slider mechanism that binds differently and resists bumping at a higher level. The sidebar wears differently too. For a Four Corners home that’s mostly concerned with key control and basic forced entry, either works. If you want the newer keyway and stronger resistance to physical attack, we usually point people to the M3. The right lock, installed right, everything else is just noise.
