Medeco Locksmith in San Antonio, CA | Strongbox Lock & Safe Co.
Medeco lock service in San Antonio typically runs $180-$420 depending on whether you need rekeying, cylinder replacement, or full mortise hardware sourcing for historic properties. We’re Strongbox Lock & Safe Co., a Residential Locksmith in San Antonio and an independent Medeco service provider - not manufacturer-affiliated - and we’ve worked these locks across San Antonio’s shifting clay soils and century-old door frames for over 42 years. The same foundation movement that makes your front door stick in August is what throws Medeco deadbolt alignment out of spec here, and we stock the OEM-compatible cylinders and antique mortise components to fix it without a second trip. Call (877) 664-8139 for a flat price before we roll.
Why San Antonio Residents Choose Us for Medeco Service
We’ve rekeyed Medeco cylinders in Alamo Heights bungalows and replaced mortise locksets in King William limestone mansions where the Historic Design and Review Commission had to sign off on every screw. That range of work teaches you what catalog specs don’t: how a Medeco Biaxial pin tolerates the grit that blows in off I-10 during drought season, or why a Maxum deadbolt binds when a 1920s door frame swells after October rains.
Gil Navarro grew up in Boyle Heights and learned this trade at Los Angeles Trade-Technical College, where a night-class instructor told him a locksmith’s real job is making people feel safe again. He’s never forgotten that. Gil built Strongbox on flat prices quoted before the truck moves, no surprise charges on the invoice, and the 90-Day Done Right Promise backed in writing. Our technicians are background-checked, uniformed, and show ID at every door in San Antonio - because the person who opens your locks should be the most verifiable person you ever hire.
We carry Medeco sales & service parts in our San Antonio inventory, not just what fits common Kwikset backsets. That means same-day resolution for most Medeco calls rather than a two-week special-order wait.
Common Medeco Locksmith Problems We Solve in San Antonio
- Deadbolt throw binding after seasonal rain. San Antonio’s Vertisol clay soils rehydrate in fall, swelling wood frames in the 78201-78210 corridor until the Medeco Maxum’s one-inch throw scrapes the strike plate. We file and reset strikes, or relocate them when frame shift is severe - we don’t just force the bolt and chew up your cylinder.
- Original mortise locksets failing in pre-1960 homes. The 1910s-1940s bungalows on San Antonio’s West Side (78207) often still run skeleton-key mortise boxes. When a Medeco rim cylinder was retrofitted decades ago, we source period-correct cast-iron strikes and antique-spec spindles rather than destroying the door with modern bore-hole hardware.
- Keyway contamination from caliche dust and pollen. San Antonio’s sustained 100°F+ summers bake fine dust into Medeco keyways. The Biaxial’s angled pins are particularly sensitive; we flush with proper lubricants, not WD-40, and cut new keys on Medeco-specific duplicators when wear has rounded the bitting.
- HDRC compliance stalls on historic district hardware. In King William (78204), replacing a failed Medeco mortise with an off-the-shelf deadbolt can trigger a Historic Design and Review Commission violation. We source or replicate period-appropriate profiles - often from salvage yards or specialty foundries - so your lock functions and your certificate of appropriateness stays clean.
- Master key system degradation in multi-unit rentals. San Antonio’s older duplex and fourplex stock near Dignowity Hill (78203) runs Medeco 32 series master keying that drifts out of spec after decades of tenant turnover. We decode existing systems, replace worn bottom pins, and rebuild master charts without scrapping the entire keyway hierarchy.
Medeco Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio’s expansive clay soils - the same Vertisol that cracks driveways across Bexar County - rack door frames on a seasonal cycle you can set a calendar by. In deep summer, frames shrink and gaps open; deadbolts rattle and latches slip. After the first hard fall rain, that clay rehydrates and swells, compressing frames until a Medeco Maxum’s hardened bolt won’t throw at all. We’ve learned to diagnose this as structural, not mechanical. In the 78207 West Side bungalows and the limestone vernacular homes of Dignowity Hill, we’ll often recommend a strike relocation or frame shim rather than selling you a cylinder you don’t need. Layered onto this, the King William Historic District carries HDRC oversight that can require period-correct mortise hardware replication - a combination of soil mechanics and preservation compliance that defines locksmith work in San Antonio in a way no neighboring city replicates. Your lock isn’t broken. Your ground is moving. We account for both.
Medeco Models & Products We Service in San Antonio
We work the full Medeco residential and light commercial line: Maxum deadbolts, Biaxial rim and mortise cylinders, the 32 series master key systems, and original Medeco High Security padlocks. Our San Antonio inventory stocks OEM-compatible cylinders, cams, and tailpieces - we don’t substitute aftermarket clones that void your key control. For the antique mortise sets common in San Antonio’s pre-1960 housing stock, we machine custom adapters when standard Medeco cams don’t interface with century-old lock bodies. If your system uses restricted Medeco keyways, we verify ownership before duplicating. Most standard cylinder swaps and rekeys ship from our local stock same-day; specialty mortise components for HDRC-compliant work may need 48-72 hours for sourcing.

FAQs - Medeco Locksmith in San Antonio
No. Strongbox Lock & Safe Co. is an independent Medeco service provider. We are not manufacturer-authorized or affiliated, which means we work on Medeco hardware you’ve already purchased or sourced elsewhere, and we use OEM-compatible parts rather than factory-direct distribution channels.
We stock OEM-compatible cylinders, cams, and pins that match Medeco specifications for key control and pick resistance. For antique mortise work in San Antonio’s historic districts, we sometimes machine custom components when original Medeco cams don’t interface with period lock bodies - always disclosed before work begins.
Most rekeys and cylinder swaps finish in 45-60 minutes on-site. Same-day scheduling is available for standard calls. HDRC-compliant hardware sourcing for King William or Dignowity Hill properties may extend to 48-72 hours for specialty components. Call (877) 664-8139 - we’ll give you a real arrival window, not a four-hour guess.
We service Maxum deadbolts, Biaxial cylinders (rim and mortise), 32 series master key systems, and Medeco High Security padlocks. If your system uses a restricted or proprietary keyway, bring proof of ownership - we verify before cutting any controlled duplicate.
Medeco’s hardened steel construction and patented key control justify a premium over basic deadbolt service, but the range above is what we actually charge - not an opening bid that triples on arrival. For exact pricing on your specific Medeco hardware and door condition, call (877) 664-8139. Estimates are free.
