Medeco Locksmith in San Antonio, NY | Novak Lock & Security
Novak Lock & Security provides independent Medeco locksmith service across San Antonio: rekeys, Medeco repair in Austin and surrounding areas, master key systems, and new high-security installations. We are not a Medeco factory center, and we don’t pretend to be one. What we are is a local shop with the specialty pinning kits and sidebar tooling to decode, rebuild, and rekey Medeco Biaxial, Medeco³, and M3/M4 cylinders on-site, without shipping your hardware off for two weeks. Call (331) 310-8471 for a written price before any work starts.
Why San Antonio Residents Choose Us for Medeco Service
We have been cutting, pinning, and servicing Medeco high-security locks in San Antonio for 15 years. That matters because Medeco cylinders are not Kwikset. They use angled cuts, rotating pins, and sidebars that most general locksmiths won’t touch, and an amateur rekey will leave you with a lock that grinds or doesn’t throw. Daniel Novak, our owner, learned high-security work the old way: apprenticing under a retired locksmith who handled commercial accounts across New York City, then spending years on tenant-turnover rekeys and Medeco retrofits before Novak Lock & Security opened its doors. The name on the van is the same name on the invoice. Every tech we send to a San Antonio job carries genuine Medeco pins and springs, and every job finishes with a documented photo record. We also provide Emergency Locksmith - San Antonio response when time-critical.
Common Medeco Locksmith Problems We Solve in San Antonio

- Medeco Maxum deadbolts that bind or won’t throw. San Antonio’s expansive clay soil shifts with every drought-rain cycle, and door frames in older neighborhoods move out of square seasonally. When the frame drops an eighth of an inch, the Maxum’s bolt hits the strike plate edge and refuses to extend fully. We recut the strike slot and realign the throw rather than forcing the lock.
- Gritty or sticking Medeco Biaxial cylinders. Original Biaxial cylinders from the 2000s are now at the 10-15 year mark. Sidebar springs weaken, pins mushroom from years of key insertion, and the cylinder starts feeling like it’s full of sand. A cleaning and rebuild with genuine Medeco parts brings back the crisp two-finger turn, assuming the housing is still serviceable.
- Medeco³ levers that spin without retracting the latch. This failure shows up constantly on rental properties around Lackland AFB and Fort Sam Houston, where military families cycle through every two to three years. The spline gear inside the key-in-lever version wears out from heavy use. It’s a mechanical failure, not a key issue, and the fix usually means replacing the cylinder assembly.
- Seized Medeco padlocks on gate hardware. San Antonio’s hard water leaves calcium scale on everything near an irrigation system. The shackle springs and ball bearings in exterior Medeco padlocks get fouled, and the key either won’t turn or the shackle won’t pop. We disassemble, clean, and re-lube with a dry lubricant that won’t attract dust.
- Lost Medeco key cards and restricted key blanks. If the previous owner never handed over the factory key card, don’t assume you’re locked out of rekeys forever. We can decode the cylinder and cut new keys from the existing pins, though we will recommend replacing the pins if there’s any sign of tampering or unknown key copies floating around.
Medeco Service in San Antonio: What Local Conditions Mean for Your Equipment
During peak PCS season from May through August, Medeco-equipped rental homes around Lackland AFB and Fort Sam Houston get rekeyed an average of once every 2.2 years, nearly double the national rate for owner-occupied homes. Every incoming military family wants the locks changed before they unpack boxes, and a large share of those properties already have Medeco hardware installed by a previous landlord or tenant. That churn produces a specific wear pattern: cylinders with good shells but exhausted pins, levers with stripped internal gears, and strike plates that have been shimmed and re-shimmed by whoever came before. In the same neighborhoods, the Blackland Prairie clay keeps moving door frames out of square, adding deadbolt binding to the rekey call. One tech visit often handles both: rebuild the cylinder to a new key, then realign the throw so the fresh rekey actually works.
Medeco Models & Products We Service in San Antonio

We service the full Medeco line that appears most often in San Antonio homes and small businesses: the Maxum deadbolt, the original Biaxial cylinder, Medeco³, and the M3 platform that upgrades to M4. That includes key-in-knob and key-in-lever configurations, rim and mortise versions where the housing allows, and exterior padlocks. We stock genuine Medeco pins, sidebars, springs, and key blanks on the truck for same-day service. When a cylinder can be rebuilt cleanly, we rebuild it. When the housing is worn past clean repair, we tell you straight and recommend a new Medeco cylinder rather than a core-only swap, because a worn housing will keep binding on the same door prep no matter what core you drop in.
Medeco Service Pricing in San Antonio
A Medeco rekey in San Antonio typically runs $25 to $35 per cylinder for the labor, plus the cost of Medeco key blanks if you need extra keys cut. A full cylinder rebuild with new pins and springs lands between $45 and $75 per cylinder, depending on the model and how far the internals have degraded. Strike realignment or deadbolt throw adjustment runs $40 to $65 when it’s part of the same visit. You get a firm written price before we dispatch, and that price is the price on the invoice, per Haven Standard Clause 1. No added call-out fee, no number that changes when the tech arrives. Call (331) 310-8471 and ask for a line-item estimate.

FAQs - Medeco Locksmith in San Antonio
Yes. We decode the existing cylinder, read the pin configuration, and rekey it to a new set of Medeco keys cut on-site. The original card just records factory key codes, which speeds up key duplication later. It is not required for us to rekey or rebuild the lock. Call (331) 310-8471 and we’ll walk you through what the tech needs to see.
Your door frame has shifted. After prolonged dry spells break with heavy rain, the expansive clay under older San Antonio homes swells and moves frames out of square, which drags the deadbolt bolt against the strike plate. The lock is usually fine; the alignment isn’t. We recut the strike slot and adjust the throw so the bolt seats without forcing it. If the frame movement is large enough, the door itself may need hinge adjustment. Call (331) 310-8471 for a diagnostic visit and a written repair quote.
At 20 years, the answer depends on the housing. If the cylinder shell is clean and the wear is confined to the pins and sidebar springs, a rebuild with genuine Medeco parts costs under $75 and restores the original feel. If the housing is worn, scored, or has been drilled at any point, a new Medeco cylinder is the honest call. We’ll tell you which one you’ve got, and we’ll price both options before any work starts.
We do, and we do them as flat per-lock pricing, not as a mystery quote. A master key system with Medeco cylinders is a surveyed job: we walk the property, count the doors, map the access levels you need, and give you a written per-lock price plus the cost of the master and sub-master keys. No dispatch-time surprises, because we don’t dispatch on those jobs; we schedule them. Call (331) 310-8471 to set a survey time.
A standard Kwikset or Schlage rekey in San Antonio typically runs $15 to $20 per cylinder in labor. A Medeco rekey runs $25 to $35 per cylinder because the cylinder must be decoded before removal, the pins are precision-angled rather than standard, and the rekey kit is brand-specific. The difference is the security you’re paying to maintain: Medeco keys cannot be duplicated at a hardware store. Call (331) 310-8471 and we’ll quote your exact door count before anyone gets in a van.
