Medeco Deadbolt Installation: The Texas Owner’s Guide
Medeco deadbolt installation in Texas typically runs $280-$420 for a complete setup, including the cylinder, strike plate, and proper door prep. We stock Medeco Biaxial and Maxum series hardware on our trucks, and most residential installs are finished within 90 minutes. Same-day appointments are available six days a week across the Houston metro and surrounding counties.
Most owners who call us about Medeco deadbolts fall into two camps: they’ve got a new Medeco cylinder they want properly installed, or their existing deadbolt has started sticking, grinding, or failing to throw fully. In Texas heat, the brass components inside a Medeco cylinder can expand and contract enough to throw off the pin tolerances, especially on south-facing doors that bake all afternoon. We’ve seen this pattern enough to know it by feel.
Which Medeco Models This Applies To
Medeco’s residential line breaks into three series you’ll encounter in Texas homes. The Medeco Maxum 11*5 is the heavy-duty deadbolt most of our customers know by sight: the thick, rectangular faceplate and the keyway with the angled sidebar cuts. The Biaxial series uses the same core technology but with an older key blank system, still common in homes built between 1995 and 2010. The 3 series is the newer residential grade, with a redesigned sidebar and tighter tolerances against picking.
To identify what you’ve got, check the key head for a stamped series number, or look at the deadbolt faceplate for a small Medeco logo and model code. The backset, the distance from the door edge to the center of the cylinder, is almost always 2-3/8″ or 2-3/4″ in residential doors. Get this wrong and the bolt won’t align with the strike. We carry both backsets on every truck.
On OEM versus aftermarket: Medeco’s factory cylinders use proprietary sidebar geometry that aftermarket copies rarely match precisely. For a deadbolt that actually earns its UL 437 rating, we install genuine Medeco cylinders. Strongbox Lock & Safe Co. of Texas is an independent service provider, not affiliated with Medeco, but we’ve handled enough of their hardware to know where the corners get cut.
Signs Your Medeco Deadbolt Installation Is Failing
- The key turns but the bolt doesn’t throw. The tailpiece connecting the cylinder to the bolt mechanism has likely sheared or slipped its set screw. This happens more often on doors that stick in the frame, forcing the user to muscle the key.
- Grinding or catching halfway through the turn. Dirt and humidity have gummed the pin stacks, or the sidebar is dragging against a worn housing. In Galveston and Corpus Christi, salt air accelerates this by half.
- The key works in warm weather but not cold mornings. Brass pins expanding against steel housings create tolerance issues. We’ve tracked this specifically in homes west of Houston where temperature swings hit forty degrees overnight.
- The bolt extends but won’t retract without jiggling. The bolt face is binding in the strike plate, usually because the door has settled or the original install didn’t account for seasonal frame movement.
- The cylinder spins freely in the housing. The retaining clip or cam has broken. On Medeco deadbolts, this clip is specific to the series, a $3 part that takes proper disassembly to reach without damaging the cylinder.
Replacement Cost & What’s Included
| Service | Price Range |
|---|---|
| Medeco deadbolt installation (new door, no prep) | $280-$340 |
| Medeco deadbolt installation (existing bore, standard backset) | $220-$280 |
| Medeco cylinder replacement into existing deadbolt | $180-$240 |
| Strike plate adjustment or relocation | $45-$75 |
| High-security door prep (steel door, composite frame) | $340-$420 |
What drives the range: door material, whether the existing bore matches Medeco’s 1-1/8″ cylinder diameter, and whether the strike needs relocation. Steel doors in newer Texas construction often need a step-bit enlargement. We quote the full price on the phone before we roll, and we stand behind it in writing. Every installation carries our 90-Day Done Right Promise, backed in writing with no extra paperwork.
DIY or Call Us?
There’s a safe middle ground here. You can verify your backset measurement with a tape measure, check that your door edge is square, and confirm the strike plate sits flush. What we don’t recommend: drilling a new bore freehand, chiseling a strike mortise without a proper jig, or forcing a cylinder into a misaligned housing. Medeco’s sidebar mechanism is precise enough that a half-degree of binding will wear it prematurely and void the warranty.
The other risk is door prep on fiberglass or steel entry systems. One slip with a hole saw and you’ve compromised a $2,000 door. We’ve rescued enough of those calls to know the flat price on the phone is cheaper than the fix. If you’re holding a Medeco cylinder and want it installed right the first time, call (844) 697-1013. We’ll walk through your door type and quote before the truck rolls.
FAQs
A properly installed Medeco deadbolt typically lasts 15-20 years in Texas, though coastal humidity and direct sun exposure can shorten that to 10-12. The cylinder itself often outlives the bolt mechanism, which takes the physical wear. If your door is sticking or the frame shifts seasonally, the hardware works harder and wears faster.
Sometimes. A gummed cylinder can be cleaned and relubricated with Houdini Lock Lube. A loose set screw can be tightened. But a sheared tailpiece, cracked cam, or worn sidebar housing means replacement, the parts are proprietary and the labor to rebuild exceeds the cost of a new unit. Call (844) 697-1013 and we’ll tell you straight which path makes sense.
Most Medeco deadbolt installations take 45 to 90 minutes from the time we park. A straightforward swap into an existing bore is closer to 30 minutes. New door prep, steel reinforcement, or strike relocation adds time. We schedule with a window, not a mystery, and we call when we’re en route.
Yes. We carry Medeco Maxum and 3 series deadbolts, both standard backsets, and the full range of cylinder configurations. If you’ve got an older Biaxial system, we may need a day to pull the specific keyway, but we’ll know after two questions on the phone. Same-day installs cover about 90% of the calls we take.
