If you own a Medeco lock in Saint Augustine Shores, you already know the problem: most locksmiths won’t touch it, and the ones who will often don’t stock the parts. Kingsley Locksmith provides independent Medeco service across Saint Augustine Shores, and the one thing that makes our Medeco work here different is that we rebuild and rekey original cylinders instead of pushing replacements that would break your street’s uniform builder-era look. We’re not authorized by Medeco, and we’ll be upfront about that, but we work on Medeco mechanical and keyway systems every week and source genuine OEM cylinders and key blanks through legitimate supply channels. Call (855) 360-5957 for a free estimate.
Why Saint Augustine Shores Residents Choose Us for Medeco Service
Medeco locks are not Kwikset. A Medeco cylinder runs on angled cuts and a sidebar that most generalist locksmiths have never rebuilt, and that’s exactly why so many Medeco owners in Saint Augustine Shores end up calling us after another company either refused the job or quoted a full replacement. The same issue drives calls for our Medeco service in Saint Augustine South. We’re independent, which means we don’t answer to Medeco’s authorization program, and it means we can be honest about what your lock actually needs. If the plug and sidebar are sound, we rebuild and rekey the existing cylinder. If they’re not, we say so plainly.
Randall Cofer, our owner and lead locksmith, learned the mechanical side of the trade through the Applied Technology program at First Coast Technical College in St. Augustine, then spent years working on residential deadbolts and commercial access systems across St. Johns County. He’s lived in this county most of his life, and he knows exactly what salt air off the Intracoastal does to a Medeco plug. That’s why we stock OEM Medeco cylinders, keys, and sidebar components for fast turnaround in Saint Augustine Shores. We also offer full Medeco sales & service across our coverage area.

Common Medeco Locksmith Problems We Solve in Saint Augustine Shores
Here are the five Medeco failure patterns we see most often in Saint Augustine Shores, each tied to the local housing stock and climate:
- Seized cylinders from salt air. Thirty-year-old Medeco cylinders on exterior doors in Saint Augustine Shores routinely seize because the salt air off the Intracoastal pits the plug and binds the sidebar. The key sticks, then snaps. This is corrosion, not tampering, and we fix it with an OEM rebuild, not a spray can of lube.
- Loose strike plates and elongated screw holes. Builder-era Medeco deadbolts on concrete-block and stucco homes develop loose strike plates after decades of door slams. The bolt no longer fully seats in the jamb, which means the deadbolt is securing nothing. We repair the jamb and reset the plate so the bolt sits correctly.
- Worn keys that work in one door and fail in the next. Original Medeco keys cut years ago on worn machines no longer lift the pins cleanly. The key works in the front door and jams in the back door. The fix is duplication from the original bitting on Medeco blanks, not another copy of a copy.
- Lost key control on older Biaxial and M3 cylinders. Older Medeco Biaxial and M3 cylinders with restricted keyways often have no key records left by prior owners. When key control is gone, a rebuild isn’t enough, you need a new cylinder to restore restricted keys.
- Builder-era hardware that can’t be replaced without breaking the look. In Saint Augustine Shores, many front-door Medeco sets still match the original tract-home hardware. Homeowners don’t want a mismatched smart lock, so we rebuild and rekey the cylinder and leave the exterior brass untouched.
Medeco Service in Saint Augustine Shores: What Local Conditions Mean for Your Equipment
Saint Augustine Shores is a deed-restricted subdivision of mostly 1970s to 1990s single-family homes, and nearly every door, deadbolt, and builder-grade lockset is now 30-plus years old. That’s a very different working environment from a newer subdivision or an apartment complex. Here, locksmith work is dominated by rekeying and rebuilding aging brass hardware on matching tract-home doors, not by urban lockouts. The salt-laden coastal air and humidity off the Intracoastal accelerate corrosion on exterior locks and hinges in a way inland St. Johns County properties simply don’t see. For a Medeco owner, that means your cylinder’s biggest enemy is not a burglar with a bump key, it’s the pitting that forms on the plug and sidebar after thirty summers of humid, salty air.
We saw this firsthand on a ranch home near the Shores’ Intracoastal side, similar to the Medeco service in Villano Beach we provide. An original Medeco Maxum deadbolt would not turn past halfway, and the salt air had pitted the plug and sidebar so badly that lubrication was useless. We pulled the cylinder, rebuilt it with OEM Medeco internals, rekeyed the front and back doors to one new restricted key, and left the original brass knob-and-deadbolt look untouched so it still matched the rest of the street. That is the kind of repair that makes sense here, and it’s one reason we stock OEM Medeco parts for Saint Augustine Shores service calls.
Medeco Models & Products We Service in Saint Augustine Shores
We work on the full range of Medeco mechanical high-security systems. That includes the Medeco Maxum deadbolt, the residential high-security deadbolt many Saint Augustine Shores homes had installed in the 1980s and 1990s. We also service Medeco M3 and M4 cylinders with their patented keyway systems, the older Medeco Biaxial cylinder that still guards a lot of commercial and residential doors in the area, and the classic Medeco Original pin-tumbler high-security cylinder. On any of these, our approach is the same: we use genuine OEM Medeco cylinders, keys, and sidebar components because Medeco tolerances do not tolerate import knockoffs. If the plug and sidebar are sound, we rebuild and rekey rather than push a replacement. We replace only when corrosion or keyway loss makes a rebuild unreliable. Most common Medeco parts are stocked locally for fast Saint Augustine Shores turnaround, and Saint Augustine Shores service area coverage means we’re nearby when you need us.
Medeco Service Pricing in Saint Augustine Shores
Medeco work costs more than standard Kwikset or Schlage service for one simple reason: the parts are more expensive, and the labor is more skilled. A basic rekey of a Medeco cylinder in Saint Augustine Shores typically runs $35 to $75 per cylinder, while a full cylinder rebuild with OEM sidebar components can run $90 to $180 depending on the model and extent of corrosion. If you need a new Medeco Maxum deadbolt installed, plan on $180 to $350 for the hardware plus installation. Every job is different, which is why we give a full price on the phone before anyone is dispatched. That quote is the price on the invoice, no call-out surcharge added when the tech arrives. Call (855) 360-5957 for a free estimate and we’ll tell you exactly what your Medeco lock needs.

FAQs – Medeco Locksmith in Saint Augustine Shores
My Medeco deadbolt key barely turns in Saint Augustine Shores humidity. Can it be rekeyed or rebuilt, or do I need a new cylinder?
In most Saint Augustine Shores cases, the cylinder can be rebuilt. The sticking is almost always corrosion on the plug and sidebar from salt air off the Intracoastal, not worn pins or tampering. We pull the cylinder, clean and rebuild it with OEM Medeco internals, and rekey it if needed. Replacement only becomes necessary when the plug or sidebar is pitted beyond reliable repair. Call (855) 360-5957 and we’ll tell you which route your lock needs before we send anyone out.
Can you rekey a Medeco lock to match a new restricted key without replacing the whole deadbolt?
Yes, as long as the cylinder is in rebuildable condition and the keyway is still under your control. We build the new restricted key from the original bitting on Medeco blanks, then rekey the cylinder to match. If key control was lost under a previous owner, we’ll need to install a new cylinder to restore restricted keys. The quote covers exactly what’s needed, no upsell at the door.
Will a Medeco high-security deadbolt fit the existing door prep on a 1980s Saint Augustine Shores concrete-block house?
Most of the time, yes. The Medeco Maxum deadbolt uses a standard 2-1/8-inch cross bore and 1-inch edge bore, which matches the prep on most 1980s concrete-block and stucco homes in Saint Augustine Shores. Where we run into trouble is worn strike plates and elongated screw holes, not the prep itself. We repair those as part of the install.
Do you stock Medeco keys in Saint Augustine Shores, or will I have to wait for key duplication?
We keep OEM Medeco key blanks and common cylinder components stocked locally, so most key duplication and rekey work in Saint Augustine Shores is done same-day. Restricted keyways like M3 and M4 may require cutting from the original bitting rather than copying a worn key, which we handle in-field. Call (855) 360-5957 for a free estimate.
Can you rekey a Medeco cylinder and leave the door hardware looking like the original builder-era style?
That is exactly what we do most often in Saint Augustine Shores. Because so many homes in this deed-restricted subdivision still have original brass knob-and-deadbolt sets, we rebuild and rekey the Medeco cylinder while leaving the exterior hardware untouched. You get one new restricted key and the same street-facing look. Call (855) 360-5957 and we’ll walk you through it.
