Medeco Residential Locksmith in Houston: What to Know First
We provide independent Medeco residential locksmith service throughout Houston, with same-day appointments for most calls and emergency response when you’re locked out. A typical Medeco deadbolt rekey or repair runs $180-$340, and we quote that flat price on the phone before our truck rolls - no bait, no switch. This page is for Houston homeowners who already have Medeco hardware on their doors and need a technician who understands the difference between a Maxum that won’t turn and a dead cylinder that needs pinning, not just drilling. If that’s your situation, call us at (833) 695-3962. A live person answers, 24/7.
How Medeco Products Fail - and How We Fix Them
- Maxum 11*5 series deadbolt - sticky or grinding turn. In Houston’s humidity, the boron alloy bolts can develop surface corrosion that binds in the strike plate, especially on north-facing doors that stay damp through our long spring seasons. We disassemble, clean the bolt carriage, and either dress the strike or replace the bolt with an OEM-spec part. We don’t lubricate and walk away - that just traps more Gulf Coast moisture.
- Medeco3 (M3) keyed knob - key won’t withdraw at neutral position. The sidebar fingers in the M3 interact with six pin stacks, and Houston’s fine caliche dust works into the keyway over years, wearing the sidebar groove. We pull the cylinder, flush with Houdini or similar non-residue cleaner, and replace the sidebar springs if they’ve lost tension. Aftermarket sidebar kits exist, but we use Medeco-spec springs to keep the pick-resistance rating intact.
- Medeco X4 residential grade - key turns freely, no latch retraction. The X4 uses a tailpiece adapter that can shear its brass pin if a homeowner forces the key against a misaligned door. We see this in older Meyerland and Bellaire homes where slab settlement has shifted the door frame. We replace the tailpiece assembly, realign the strike, and test the full throw before we leave. Done right - and backed in writing.
- Medeco Original (pre-2005) - key works, but the lock won’t accept a duplicate. Early Medeco biaxial cylinders used a proprietary key blank with angled cuts that later locksmiths often miscut on standard equipment. We stock the correct 60-series blanks and cut on a Medeco-compatible duplicator. If the warding is too worn, we rekey to a fresh bitting rather than sell you a cylinder you don’t need.
- Medeco deadbolt - latch bolt stuck extended, door won’t close. The auxiliary spring that returns the bolt can fatigue in Houston’s heat cycles, particularly on dark-colored doors that hit 140°F in August. We replace the spring pack with OEM parts; aftermarket springs vary in wire gauge and will fail again in two years. We quote it flat before the truck rolls, and we put it in writing when the job is done.
Our Medeco Residential Locksmith Process
- 1
Call and diagnose. You describe the symptoms. We ask which Medeco line you have - Maxum, M3, X4, or older biaxial - and what the key is doing. We quote a flat price range before we dispatch.
- 2
Arrive and verify. Our technician shows ID at the door in uniform. We confirm the model, check for frame shift or door binding, and inspect for previous repair attempts that may have damaged the cylinder.
- 3
Parts decision. If the cylinder is salvageable, we rekey or repair with OEM-spec components. For a failed M3 sidebar or Maxum bolt, we use Medeco factory parts. For a worn X4 tailpiece, quality aftermarket is available, but we explain the trade-off in warranty coverage and let you choose.
- 4
Repair and test. We cycle the lock fifty times, test with all provided keys, and verify the deadbolt throw clears the jamb without binding. If we installed a new cylinder, we record the key code for your records.
- 5
Written guarantee. You get a printed invoice with the 90-Day Done Right Promise. If anything fails from our workmanship or parts, we come back. No paperwork to file, no argument.
- 6
Cleanup. We remove old parts and debris. You check the work. Then we leave.

What moves the price: double cylinders cost more to rekey; mortise installations in older Houston homes take longer; after-hours or holiday calls carry a flat surcharge we disclose upfront.

FAQs
No - rekeying by a qualified locksmith does not void Medeco’s limited lifetime warranty on mechanical defects, provided OEM parts are used and the cylinder is not drilled or modified. We use factory-spec components and document the work so your warranty stays intact. Call (833) 695-3962 if you need warranty guidance for your specific Medeco line.
Yes - we stock common Maxum, M3, and X4 cylinders, bolts, and sidebar components on our Houston service trucks. For older biaxial or discontinued lines, we source within 24-48 hours from our distributor. If you’re locked out today, we have bypass methods that don’t destroy your cylinder while we wait on a part. Call (833) 695-3962 - we’ll tell you exactly what we have in stock.
Repair is usually cheaper if the cylinder body and housing are sound - a rekey or sidebar spring replacement runs $180-$340 versus $380-$520 for full replacement. We assess this on-site and give you both numbers before any work begins. If the door frame is damaged or the cylinder has been drilled previously, replacement may be the only sound option. Call for a free estimate.
Same day for standard calls, typically within 60-90 minutes for emergencies inside the Loop and most of Harris County. After 10 p.m. and on holidays, we still answer live and dispatch - just with the disclosed after-hours rate. We’ve opened Medeco deadbolts for Houston homeowners at midnight on Christmas Eve; the technician still showed ID and quoted flat before starting.
We do both - new installation and service. As an independent Medeco service provider, we are not affiliated with or authorized by Medeco, but we install their hardware correctly to factory specifications and back our work with the 90-Day Done Right Promise. We also install Schlage, Kwikset, and other brands if you want to compare options for a given door. Call (833) 695-3962 for recommendations based on your specific entry.
