We provide independent Medeco locksmith service across Sunnyvale, TX – rekeying, repair, and installation of Medeco Maxum deadbolts, M3 cylinders, and commercial mortise hardware – plus Medeco service in Travis Ranch. What sets our Medeco work apart here is the shape of Sunnyvale itself: acreage properties, perimeter gates, and outbuildings mean a Medeco call often starts at a gate padlock or workshop cylinder rather than the front door. We’re Stalwart Locksmith, led by Russ Thibodeau, and we carry genuine Medeco cylinders, pins, and restricted key blanks for same-week service in the 75182 ZIP. Call (877) 626-0257 for a free estimate before you roll a truck.

Why Sunnyvale Residents Choose Us for Medeco Service
Medeco isn’t a sideline for us. Our bench sees Medeco cylinders come through for decoding, re-pinning, and retrofitting every week, which means a Sunnyvale homeowner with a Maxum deadbolt or an M3 rekey isn’t getting a tech who fumbles through it. We’re an independent shop – no manufacturer authorization claimed, just daily hands-on work with the hardware itself. Medeco sales & service is a core part of what we do, from restricted keyway rekeys to fresh installations.
Russ Thibodeau came up through the vocational locksmithing program at Tarrant County College and has spent more than a decade on North Texas locks, including the kind of high-security cylinders most general locksmiths pass on. He’s built our shop around a simple standard: if the cylinder pins cleanly and the key turns, we re-key and adjust. If the hardware has moved or seized, we fix the mounting. We don’t push replacements that aren’t needed. That matters in Sunnyvale, where a gate padlock and a house deadbolt might both carry Medeco keyways and both need to work on one restricted key.

Common Medeco Locksmith Problems We Solve in Sunnyvale
- Restricted keyways and lost keys: On acreage properties, spare keys get handed to gate crews, contractors, and family members. When one of those keys doesn’t come back, a simple hardware-store copy isn’t possible. We decode the existing cylinder, re-pin it, and issue fresh restricted keys through the proper controlled blank – so the security you paid for isn’t quietly erased.
- Gate padlocks that seize in North Texas heat: Outdoor Medeco padlocks and rim cylinders on Sunnyvale gates collect grit, dust, and heat from long private lanes. After a summer of that, the shackle binds and the pin chambers gum up. Usually the cylinder is fine – it needs disassembly, cleaning, and re-lube rather than replacement.
- Deadbolts that stick or bind after dry summers and clay movement: Expansive clay soil under Sunnyvale shifts gate posts and door slabs. A Medeco Maxum that threw smoothly in spring starts binding after a dry summer or a heavy storm season. The cylinder hasn’t failed; the strike and bolt no longer line up. We realign, adjust, and get it smooth.
- Improperly pinned cylinders from past work: We occasionally open up a Medeco on an older Sunnyvale home and find mis-keyed pins or sloppy installation from a previous tech. The key turns stiffly or not at all after hardware shifts. We re-pin to factory spec with genuine Medeco pins.
- Mixed hardware across house, shop, and gate: Sunnyvale properties often have three or more Medeco cylinders on different structures. When they’re keyed to different keys, it’s a headache. We key everything to one restricted system so one key works everywhere on the parcel.
Medeco Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale sits inside the Dallas – Fort Worth metroplex but doesn’t feel like it. It’s one of the smallest, most rural-feeling towns in the metro, and that changes what Medeco service looks like here. A call that starts as “my deadbolt won’t turn” often becomes a gate padlock rekey, a workshop cylinder decode, and a front-door adjustment on the same trip, similar to how we handle Medeco in Balch Springs. The address frequently isn’t visible from the road, and the first locked thing we pass is usually a perimeter gate, not a front door. We confirm gate access before we roll so we’re not sitting at the wrong end of a private lane.
North Texas heat and expansive clay also do predictable things to high-security hardware. Gate posts shift. Door slabs settle. A Medeco cylinder that was perfectly pinned in spring binds by August because the latch no longer lines up with the strike. That’s not a cylinder failure – it’s the ground moving under the house. We’ve worked enough Sunnyvale acreage and older town-core homes to know the difference, and it saves you a replacement quote you didn’t need.
Medeco Models & Products We Service in Sunnyvale
We service the full Medeco line most common on Sunnyvale residential and light commercial properties: the Medeco Maxum deadbolt, Medeco M3 (Medeco3) keyway cylinders, Medeco Original (Original Biaxial) cylinders, and commercial mortise and rim cylinders. For restricted-keyway work, we use genuine Medeco cylinders, keys, and pins – anything less breaks the key control you paid for. For non-restricted mechanical parts like strikes, reinforcement plates, and hinges, we fit quality aftermarket hardware where it makes sense. If your Medeco cylinder still pins and turns cleanly, we re-key and adjust rather than upselling a replacement. That’s the standard Russ runs the shop by.
Medeco Service Pricing in Sunnyvale
Forney Medeco service pricing is comparable to what we offer here: Medeco service in Sunnyvale typically runs $85 – $145 for a standard rekey on a single cylinder, with each additional cylinder keyed to the same system adding less. A seized gate padlock or rim cylinder that needs disassembly, cleaning, and re-pinning usually falls in the $110 – $180 range. New Medeco Maxum deadbolt installations run higher, and we quote those by the specific hardware and prep work involved. The price we give you on the phone is the price on the invoice – no call-out surcharge added when we arrive, no bait pricing. Call (877) 626-0257 and we’ll give you a firm number before anyone is dispatched.

FAQs – Medeco Locksmith in Sunnyvale
Can you re-key a Medeco lock in Sunnyvale, or do I have to go through Medeco? You can absolutely work with an independent locksmith, and that’s what we are. We’re not manufacturer-affiliated or authorized by Medeco – we’re a local shop that specializes in their hardware. We stock Medeco pins, key blanks, and cylinders for restricted keyways, and we re-key them daily. You don’t need to ship anything to the manufacturer or wait on a dealer. Call (877) 626-0257 and we’ll tell you exactly what your rekey involves.
My Medeco gate padlock on a private lane won’t turn after the summer – is it ruined? Usually not. North Texas heat, grit, and blowing dust work their way into the shackle and pin chambers on outdoor padlocks, and after a season of that the key binds or won’t insert cleanly. We take the padlock apart, decode the cylinder if needed, clean out the grit, re-pin or re-lube, and get it turning smoothly again. Replacement is the last resort, not the default. Call (877) 626-0257 and we’ll quote the repair over the phone.
Why does my Medeco deadbolt stick only in certain seasons? It’s the clay under your house. Sunnyvale sits on expansive soil that swells with moisture and shrinks in drought. When it moves, your door slab and strike plate shift a fraction of an inch – enough to make a precisely machined Medeco bolt bind against the strike. The cylinder isn’t the problem; the mounting has moved. We realign the strike, adjust the deadbolt, and it throws cleanly again.
Can I get one restricted Medeco key to work on my house, shop, and gate? Yes, and this is one of the most common requests we get on Sunnyvale acreage properties. We key all your Medeco cylinders – house deadbolt, shop padlock, gate cylinder – to a single restricted system. One key turns everything, and the restricted keyway means nobody’s running it to a hardware store for an unauthorized copy. We’ll walk you through the key count you need and quote the full job before we start.
Do you install Medeco high-security deadbolts on older Sunnyvale homes near the town center? We do. The older homes near the town center often have thinner door slabs and pre-bored holes sized for standard deadbolts, so a Medeco Maxum installation sometimes needs door prep and strike reinforcement. We handle that without a second contractor. We’ll inspect the door, tell you what’s actually needed, and quote the install flat before we begin. Call (877) 626-0257 for a free estimate.
