Medeco Locksmith in Katy, TX | Novak Lock & Security Katy
Medeco lock service in Katy typically runs $180-$420 depending on whether we’re rekeying an existing cylinder, replacing a silt-damaged plug, or installing a new Maxum deadbolt in a standard tract-home door prep. Most calls in Katy are same-day, and every job starts with a written price quoted by phone that the technician cannot change on arrival - Haven Standard Clause 1. For businesses, see our Commercial Locksmith in Katy. Call (832) 402-8386 for a firm quote before anyone is dispatched.
We’re Novak Lock & Security Katy, an independent Medeco service provider - not manufacturer-authorized, not franchise-affiliated. We’ve cut Medeco keys, decoded rotating pin stacks, and rebuilt Medeco cylinders across this city since long before the latest master-planned community broke ground. Our truck stocks OEM Medeco pins, springs, sidebars, and key blanks because the rotating-pin geometry Medeco uses doesn’t tolerate soft aftermarket internals.
Why Katy Residents Choose Us for Medeco Service
Katy is a strange market for a locksmith. The housing stock is almost comically uniform - Perry Homes, Lennar, D.R. Horton, all using the same Kwikset SmartKey deadbolts in the same 2-1/8″ door bores. When a homeowner in Seven Meadows or Grand Lakes decides to upgrade, the Medeco Maxum or M3 drops straight in. A Katy Residential Locksmith like us handles this swap routinely. No door modification. No filler plates. We know this because we’ve done it hundreds of times.
Daniel Novak, our owner, grew up in Culver City watching his uncle rekey apartment complexes - enough to know the trade rewards diagnosis more than force. He trained at West Los Angeles College, where the locksmithing coursework was hands-on and short on theory that collapses under a real service call. For the last several years he and his crew have served Katy, including jobs at LaCenterra at Cinco Ranch where he’s rekeyed ground-floor retail and residential units above the shops. He still keeps a worn Medeco spec sheet in his truck. Not because he needs it - because he likes having the numbers in front of him when he’s explaining a cylinder upgrade. Name the part, name the price, describe what was found.
We’re independent, which matters for Medeco work. We can match a Medeco cylinder to whatever deadbolt, rim, or mortise hardware your door already has. No proprietary package pushed. No warranty pitch tied to a manufacturer’s preferred installer list. Just the lock you need, quoted in writing before we start, with a documented photo record left when we leave.
Common Medeco Locksmith Problems We Solve in Katy

- Corroded rotating pins from Gulf Coast humidity. Katy’s humidity routinely climbs above 80%, and that moisture finds the hardened steel rotating pins inside Medeco cylinders. The key feels gritty. Sticks halfway. We see this most on west-facing Maxum deadbolts that bake in afternoon sun, then cool into evening condensation. We pull the plug, replace corroded pins with OEM parts, and lubricate with Medeco-specified graphite - never oil, which traps moisture.
- Silt-packed cylinders in post-Harvey flood zones. Subdivisions west of Barker Reservoir - streets that took controlled reservoir releases during Harvey - still produce “flood-zone flips” where fine silt packed into Medeco pin chambers and sidebar grooves. The key inserts, but won’t turn fully. Decoding jams the plug. We don’t waste your money repinning a silt-packed cylinder; we replace with new OEM and rekey to your existing key.
- Swollen door frames misaligning strikes. Katy’s wet season swells wooden frames and shifts strike plates. The Medeco deadbolt is fine. The cylinder is fine. The bolt simply can’t enter a strike that’s moved 1/8″. We realign, shim, and test - reporting what we found, not inventing a lock failure.
- Worn key blanks on older Classic and M3 cylinders. Keys recut one too many times, or cut on the wrong blank initially, develop shallow bitting that no longer lifts rotating pins to the correct shear line. The homeowner thinks the lock failed. Usually it’s the key. We cut a new OEM blank from factory specifications and test before we leave.
- Builder-grade preps that almost fit. Those uniform Katy tract homes? The door bore is standard, but the backset or cross-bore depth sometimes varies by builder batch. A Medeco Maxum that drops into a Perry Homes build in Firethorne may need a minor adjustment in a D.R. Horton build from the same year. We’ve seen enough of them to know which batches need what.
Before
AfterMedeco Service in Katy: What Local Conditions Mean for Your Equipment
Here’s a Katy-specific pattern that doesn’t show up in locksmith forums for Houston or Sugar Land. Because Katy’s dominant housing stock is near-identical post-2000 tract construction - Perry, Lennar, and D.R. Horton homes with the same builder-grade door preps - a Medeco Maxum or M3 cylinder usually drops into the existing bore without door modification. That’s why so many Katy homeowners upgrade to Medeco rather than a cheaper brand when their SmartKey deadbolt starts binding. The labor cost is lower because we’re not routing, filling, or re-drilling. The security gain is higher because Medeco’s rotating-pin system resists picking and bumping that standard cylinders don’t. And in neighborhoods like Cinco Ranch, where HOA covenants sometimes specify “substantially similar” exterior hardware, a Medeco Maxum in brushed nickel often satisfies the architectural committee where a smart lock with a camera wouldn’t.
The flood factor is equally specific to Katy. In 2017, Harvey’s controlled releases from Barker Reservoir inundated subdivisions that had never flooded before. Locksmiths working those homes discovered that even brief submersion deposits fine silt inside SmartKey cylinders - and inside Medeco cylinders too - that causes re-keying tools to jam. Many homes quietly needed full lock replacements rather than simple rekeying. We now anticipate this any time a post-Harvey flood-zone flip comes on the market. If your home is in that zone and your Medeco key started sticking after any water event, tell us when you call. We’ll bring a replacement cylinder, not just a pinning kit.
Medeco Models & Products We Service in Katy

We stock and service the Medeco lines that actually appear on Katy doors:
- Medeco Maxum - residential grade, single- and double-cylinder deadbolts. The most common upgrade from Kwikset SmartKey in Katy tract homes. We stock single- and double-cylinder versions in common finishes.
- Medeco M3 / M100 - hardened high-security deadbolt with rotating pin tumblers. Specified by some Katy commercial tenants and homeowners who want the highest pick resistance available in a mechanical lock.
- Medeco Classic / Medeco Original - older retrofit cylinders still on many 1990s-2000s Katy homes, especially in the original Cinco Ranch sections. We carry key blanks and can rebuild or replace.
- Medeco eCylinder / Medeco CLIQ - electronic cylinder, keypad or fob-controlled. Showing up on newer custom builds and small commercial suites in mixed-use developments near I-10. We service and reprogram; we don’t install access-control networks.
Our approach is OEM-first. Medeco’s rotating-pin geometry is unforgiving of soft aftermarket internals. When a cylinder is silt-packed, corroded, or the sidebar teeth are worn flat, we tell you honestly that replacement is the better spend. We don’t repin a cylinder that will fail again in a month. That’s Haven Standard Clause 3: document what you found, recommend what lasts.

FAQs - Medeco Locksmith in Katy
Gulf Coast humidity has likely corroded the rotating pins inside your cylinder, or water infiltration has carried fine silt into the pin chambers. Both conditions cause the key to insert but not rotate fully. We pull the plug, inspect for corrosion or debris, and replace with OEM parts if needed. Call (832) 402-8386 - we’ll quote the repair range before we head out.
We can rekey any Medeco cylinder to match your existing Medeco key, provided the keyway is compatible. You don’t need new locks unless the cylinder itself is damaged beyond repinning. We verify this before ordering parts. For a free compatibility check, call (832) 402-8386 with your key in hand.
Almost certainly yes. Perry Homes in Seven Meadows used standard 2-1/8″ door bores with 2-3/4″ backsets in that era. The Medeco Maxum drops into the same prep. We’ve done this exact swap dozens of times in Seven Meadows and similar Katy MPCs. The door doesn’t get cut. The upgrade takes about 45 minutes. Call (832) 402-8386 for a firm installed price.
Both, depending on exposure duration. Brief submersion often deposits fine silt that jams the sidebar groove and pin chambers - cleanable in theory, but the silt is abrasive enough that repinning usually fails within weeks. Extended submersion corrodes the hardened steel rotating pins directly. We assess each cylinder individually and recommend replacement when the damage will outlast a repair. If your home is in a post-Harvey flood zone, mention it when you call.
Yes, if you have at least one working key. We decode the existing key’s bitting and cut new OEM blanks to match. If you’ve lost all keys, we can decode the cylinder itself and create a new key - a more involved process that costs more but doesn’t require lock replacement. Either way, we quote the full price before starting. Call (832) 402-8386 with details.
