We provide independent Medeco service across Lewisville, TX: rekeys, deadbolt installs, restricted key cutting, and repair of seized or worn Medeco cylinders, plus Medeco in Highland Village and surrounding areas. What makes our Medeco work different here is that we see the same Lewisville conditions every week: settled 1960s and 1970s door frames in the older core that throw a deadbolt out of alignment, and brand-new multifamily buildings near 75067 and 75077 where restricted key systems get handed off to new tenants. We’re not authorized by Medeco, and we don’t need to be. We stock the cylinders, pins, and restricted blanks to do the work right. Call (877) 626-0257 for an estimate over the phone, free.

Why Lewisville Residents Choose Us for Medeco Service
Most locksmiths in Lewisville can cut a Kwikset key. Far fewer can pin a Medeco Biaxial cylinder, service a Maxum deadbolt that’s been fighting a warped North Texas door frame, or walk a property manager through a restricted-key audit after a tenant turns over a unit. That’s the work we do regularly at Medeco sales & service, and it’s the reason we treat Medeco as a specialty, not an add-on.
Russ Thibodeau, our owner, learned the trade through the hands-on program at Tarrant County College, where mechanical precision was drilled into him early. He’s spent more than a decade working locks from basic Schlage entry sets up to Medeco, Mul-T-Lock, and Abloy restricted systems, and he still works the bench himself. We don’t hand Medeco jobs to a junior tech who’s never seen a sidebar lock. If your cylinder comes to us, it gets pinned and checked by someone who knows what a misloaded sidebar sounds like.
We’re independent. That means we’ll tell you when a Medeco cylinder is worth rekeying and when it’s honestly spent. It also means we’re not tied to a dealer program that marks up parts. Genuine Medeco parts, fair labor, and a straight answer.

Common Medeco Locksmith Problems We Solve in Lewisville
Here’s what actually comes through our door from Lewisville addresses, week after week.
- Seized or stiff-turning cylinders on sun-facing doors. West and south exposure in Lewisville means 100°F summer afternoons baking brass cylinders until the factory lubricant turns to varnish. We disassemble, clean, re-lubricate, and rekey a seized Medeco M3 or Biaxial back to like-new rotation without replacing the whole lock.
- Deadbolt that no longer throws cleanly into the strike. Lewisville’s clay soil moves, and the older doors around downtown and the 75057 ZIP have had fifty years to settle out of square. A Medeco Maxum bolt dragging on the strike plate is usually a door alignment problem, not a lock problem. We reset the strike, adjust the slab, and restore clean operation.
- Worn or bent restricted keys that stick halfway. Medeco keys carry angled cuts and sidebar tracking. After years on a keyring, the tip rounds off, the key hangs in the stack, and the owner thinks the lock is failing. We cut fresh restricted keys from code or by hand and confirm the cylinder’s pinning before you leave.
- Lost key cards and uncontrolled duplicates. We get calls from Lewisville homeowners and business owners who bought a Medeco system, moved in, and realize the previous owner’s brother still has a key. If you can’t account for every key on a restricted system, the system isn’t restricted anymore. We rekey the cylinders, produce a fresh set, and document the new key control list.
- Retrofitting Medeco into builder-grade entry sets. The 1980s-to-2000s subdivisions around Lewisville came with brass Kwikset and Weiser knobs. We swap the cylinder for a Medeco high-security core, keep the existing trim where it makes sense, and give the door real pick-and-bump resistance without replacing every piece of hardware on it.
Medeco Service in Lewisville: What Local Conditions Mean for Your Equipment
Lewisville sits right where I-35E, SH-121, and the Sam Rayburn Tollway cross, and the housing stock reflects that growth. A single route for us can start in a 1960s brick ranch near Old Town and end at a build-to-rent community near 75067 or 75077, with Medeco service in Double Oak just as accessible. Those older ranch doors have settled and shifted for decades, so a “simple rekey” often becomes a strike-plate adjustment and a deadbolt realignment before the new keys will even turn smoothly. The frames are out of square, the hinges have worn, and a Medeco bolt, which is cut with tight tolerances, won’t tolerate the misalignment a loose Kwikset might shrug off. In the newer construction, the lock hardware is fresh but the key control is often a mess: multiple master keys floating, no record of who holds what, and a property manager who inherited a system from the original builder. That split, settled Old Town doors on one end of the route and brand-new restricted key handoffs on the other, is the most Lewisville-specific part of our Medeco work. It means our techs carry door-shimming tools and a full key-pinning kit in the same truck, every day.
Medeco Models & Products We Service in Lewisville
We work on the full Medeco line that’s common in Lewisville: the Maxum deadbolt, M3 cylinders with the patented keyway, Biaxial deadbolts and rim cylinders, and the Maxum 11WC commercial mortise cylinders you’ll find on storefront doors along the 121 corridor, with Medeco in Hickory Creek covered on our routes as well. For anything that stays on a Medeco system, we use genuine Medeco cylinders, pins, and restricted key blanks. We don’t sub in aftermarket cylinders and call it equivalent. Around the lock, where it’s about performance rather than key control, we use quality aftermarket strikes, reinforcement plates, and hinges to keep the cost reasonable. The bench stock we carry for Lewisville routes covers the common Medeco pinning kits and blank profiles, which is why we can usually turn a rekey around the same day rather than ordering parts and coming back.
Medeco Service Pricing in Lewisville
Medeco work costs more than a standard Schlage or Kwikset rekey, and the reason is straightforward: the cylinders are tighter-tolerance, the key blanks are restricted and traceable, and the work takes longer to do correctly. A Lewisville Medeco rekey typically runs from $45 to $95 per cylinder, depending on whether we’re pinning a standard 5-pin Biaxial or an M3 with sidebar coding. A new Medeco Maxum deadbolt installed tends to land between $225 and $410, including labor and a fresh restricted key set. When a door frame has settled, and we’re realigning the slab and resetting the strike, that adds $60 to $140 depending on what’s out of square. We quote the full price on the phone before anyone rolls a truck, and that quote is the invoice price. No dispatch fee, no surcharge added at the door. Call (877) 626-0257 for an exact estimate.

FAQs – Medeco Locksmith in Lewisville
Yes. We cut Medeco restricted keys on our own code equipment and maintain the key-control records that keep the system meaningful. If you have a valid key card for your system, we cut to it. If you don’t, we rekey the cylinder and start a fresh control list. Call (877) 626-0257 to confirm your keyway before you drive over.
Summer stiffness in Lewisville is usually the lock, not the door. North Texas UV and triple-digit heat bake the brass and dry out the internal lubricant until the Bible pins drag. We clean, re-lubricate, and rekey the cylinder, and check the door alignment while we’re there. Call (877) 626-0257 for an exact quote.
In most cases, yes. We swap the original cylinder for a Medeco high-security core and keep the existing trim when it’s in decent shape, which gives you pick resistance and restricted keys at about a third the cost of replacing every lock on the house. We’ll assess the hardware and tell you if the knob or deadbolt body is worth keeping. Call (877) 626-0257 for an exact quote.
A Medeco rekey involves angled pin cuts, sidebar tracking, and a restricted keyway, so it takes longer and demands more precision than a standard Schlage or Kwikset rekey. We also record every key cut and update the control ledger, which is what makes the restricted system enforceable. If your Medeco system’s records are already scattered, we rekey and rebuild the key list from scratch. Call (877) 626-0257 for an exact quote.
Yes. We rekey, expand, and audit Medeco master-key systems for Lewisville businesses, from single-storefront offices to multi-door commercial buildings. We document every cylinder, produce a fresh master and change-key schedule, and hand over a clean key-control log. Management gets the master; employees get what they need; nobody gets keys you can’t account for. Call (877) 626-0257 to schedule a survey.
