We provide independent Medeco cylinder service, rekeying, and deadbolt installation across Katy, TX. What makes our Medeco work here different is simple: most of the Medeco locks we touch in Katy were installed to fix a specific local problem, not as an upgrade someone read about in a catalog. If you need a Medeco cylinder serviced, rekeyed, or installed in Katy, call (833) 589-8049 for a straight answer and an honest price.
Why Katy Residents Choose Us for Medeco Service
We work on Medeco cylinders and hardware every week in Katy, from Biaxial retrofit deadbolts in older Cinco Ranch homes to Maxum high-security sets on new builds along the I-10 corridor. That means we know the pin stacks, the keyway families, and the restricted-key paperwork that most general locksmiths don’t. We’re an independent Medeco service provider, not authorized, sponsored, or endorsed by Medeco. That independence matters: it means our recommendation is based on what the lock actually needs, not what a manufacturer program tells us to sell. Glen Pickett, our owner and lead locksmith, trained in locksmithing and security systems at Alvin Community College, and he’s spent decades working locks across this area before founding Knight Locksmiths. We stock OEM Medeco cylinders, tumblers, springs, and restricted key blanks specifically for fast turnaround in Katy, and our full Medeco sales & service page explains our parts policy in detail.

Common Medeco Locksmith Problems We Solve in Katy
- Humidity-bound cylinders on exterior doors. Gulf Coast humidity works its way into Medeco’s hardened exterior finishes and the small springs and tumblers inside the cylinder. You notice it as a key that goes in fine but turns hard, especially on porch doors and rear garage-entry doors in Katy. We disassemble, clean, and re-lubricate with aerospace-grade lubricant, then test the cylinder off the door before re-installing.
- Deadbolt misalignment from seasonal wood movement. Katy homes built in the 1990s and later often have wood door slabs that absorb moisture all summer and dry out in winter. A Medeco deadbolt that lined up in October can drag against the strike plate in August. The cylinder feels frozen but it’s the door. We re-set strikes, adjust hinge reveals, and realign bolt paths.
- Lost or bent restricted Medeco keys. Biaxial and M3 keys use controlled blanks. You can’t grab a copy at a kiosk or big-box key machine. When a restricted key gets lost or bent, the cylinder needs re-pinned or re-keyed by someone with legitimate restricted-blank access. We handle that paperwork and key control the right way, not a shortcut way.
- Medeco cylinders retrofitted into builder-grade housings. We see this a lot in Katy’s master-planned communities: a nice Medeco cylinder dropped into the cheap Kwikset deadbolt housing the builder installed. The housing loosens, spins, or can’t throw the bolt fully because the underlying bolt isn’t engineered for the cylinder’s torque. We replace the whole deadbolt assembly when that’s what’s called for.
- Storm-season corrosion from wind-driven rain. Spring and fall storm lines in Katy push rain horizontally against exterior hardware. Medeco’s finish is durable, but the O-ring and tailpiece seals degrade over time. We replace worn gaskets and install weather-rated collars on exposed cylinders before corrosion reaches the pin chamber.
Medeco Service in Katy: What Local Conditions Mean for Your Equipment
Here’s the thing about Medeco in Katy that doesn’t show up in any manufacturer manual: in master-planned phases like Cinco Ranch, the builder keyed every home in a section alike. So when a homeowner upgrades to a restricted Medeco cylinder for real security, that single swap is often the first time their key stops working in a neighbor’s door. It’s a strange local reality, but it means Medeco work here frequently starts with a call that sounds like “my key opens the wrong house.” We pulled a shared builder-grade deadbolt from a Cinco Ranch Medeco service customer a few months back after she realized her key still opened the neighbor’s door, installed a Medeco Maxum high-security cylinder with restricted keys, and re-keyed the rear garage-entry door to match. Because her wood slab had warped from humidity, we also re-set the strike so the Maxum bolt threw cleanly every time. She left with two restricted keys and a front door that no phase-neighbor can open. That’s the actual job, the way it actually plays out in Katy.
Medeco Models & Products We Service in Katy
We provide Medeco service in Fulshear and across the full Medeco residential and light-commercial line in the 77450, 77491, 77492, and 77493 ZIP codes. That covers Medeco Biaxial deadbolt cylinders, Medeco Maxum high-security deadbolts, Medeco M3 patented-keyway cylinders, and the older Original or Classic pin-tumbler cylinders still found in some Katy homes. For every Medeco job, we use OEM cylinders, tumblers, springs, and restricted key blanks. Aftermarket Medeco-compatible parts compromise the pick- and bump-resistance that’s the whole reason to own Medeco in the first place. We’ll tell you honestly when a cylinder is repairable versus when the cost of new OEM internals makes a fresh Medeco cylinder the better financial call. Our Katy service truck carries the most common Medeco deadbolt finishes in satin nickel and aged bronze, so most installs don’t wait on a parts order.
Medeco Service Pricing in Katy
What drives the cost is the scope, not guesswork: a simple cylinder cleaning or re-lubrication runs $45 to $85. Rekeying a Medeco Biaxial or M3 cylinder with restricted blanks typically runs $35 to $65 per cylinder plus keys. Full deadbolt replacement, including a new Medeco Maxum high-security set with labor, runs $220 to $380. A full-house rekey, multiple cylinders, restricted key control setup, or door realignment work pushes the total higher. Our estimate is free and the price we quote on the phone before dispatch is the price on the invoice. No call-out surcharge added on arrival, no bait price. Call (833) 589-8049 for an exact number on your specific job in Katy.

FAQs – Medeco Locksmith in Katy
No. We’re an independent Medeco service provider. That’s not a disadvantage, it’s a distinction. We work on Medeco cylinders and restricted key systems every week in Katy, including Medeco in Pecan Grove, and we use OEM Medeco parts exclusively for Medeco cylinders. We aren’t tied to any manufacturer incentive, so our recommendation on repair versus replace comes from what the lock actually needs.
Yes, storm-driven rain is the single biggest environmental threat to exterior Medeco hardware in Katy. The hardened finish resists corrosion, but the O-ring seals and tailpiece gaskets dry out and crack over time, especially on west-facing doors that catch the strongest spring storm lines. When water gets past the gasket, it carries dissolved salts and minerals into the pin chamber, causing bind and sticky keys. We replace the seals and install weather-rated collars before the cylinder internals are compromised. Call (833) 589-8049 before the next storm front knocks out your deadbolt.
A single-cylinder rekey or re-lubrication usually takes 20 to 40 minutes on site. Full deadbolt replacement, including a Maxum high-security set, takes an hour to 90 minutes. Door realignment to fix a humidity-warped slab extends the job. If you’re in Katy proper, most appointments are scheduled same-day, and we quote the exact window when you call.
Biaxial, Maxum, M3, and the older Original or Classic pin-tumbler cylinders. If you’ve got a Medeco cylinder still in service from a 1990s-era Katy home and you’re not sure which model it is, bring it in or send a photo. We’ll identify it and tell you whether restricted keys are still available for that keyway family.
Plan on $220 to $380 for a new Medeco high-security deadbolt with restricted keys, installed, in Katy. If you want the rear garage-entry door and any secondary lock re-keyed to match, that’s additional per cylinder. Call (833) 589-8049 and we’ll give you a flat price before anyone gets in a truck. Estimates are free.
