If you need Medeco locksmith service in Mentone, here’s the short version: we’re an independent shop that services, rekeys, and installs Medeco high-security hardware across the 92359 ZIP code, and the work here often looks different than Medeco repair in Redlands or other nearby towns. Mentone’s horse properties and half-acre lots mean a Medeco key system frequently has to span a house, a tack room, a gate, and a detached garage. We handle that. Call (866) 497-9415 and we’ll tell you what a fix will take before anyone rolls out.
Why Mentone Residents Choose Us for Medeco Service
Medeco locks are not Kwikset. The cylinders use a patented pin-and-sidebar design, restricted keyways, and key-control numbers that make unauthorized duplication flat-out impractical. A lot of general locksmiths won’t touch them because the tooling and knowledge aren’t there. We work on Medeco’s high-security cylinders every week: picking, servicing, and rekeying Medeco deadbolts and rim cylinders, including the Maxum line, the M3, and the older Biaxial keyway systems. Medeco sales & service is not an add-on for us; it’s part of the regular rotation.
Gil Tanner, our owner, has spent the better part of three decades working locks across the Inland Empire, including Medeco in Yucaipa and surrounding communities. He’s the first one to say that a lock is only as good as the installation behind it. That matters out here in Mentone, where door frames settle, gates sag, and a deadbolt that doesn’t align right will bind in the first heat wave. We service what Medeco designed, but we also check the mount, the strike plate, and the alignment. On a property off Mentone Blvd with a grading issue, that’s the difference between a lock that works for ten years and one that jams every June.

Common Medeco Locksmith Problems We Solve in Mentone
- Restricted keyways that can’t be copied at the hardware store. Medeco keys are cut on a different angle system and protected by key-control numbers. When a horse property owner loses the last working key, a quick copy isn’t possible. We rekey or rebuild the cylinder so you have a working restricted key system again, with the key control restored.
- Sticking or binding cylinders on gates and sheds. The hot, dry summers and dusty Santa Ana winds in Mentone are hard on exposed hardware. Pin tumblers on Medeco gate and shed cylinders collect fine dust, lubricants dry out, and keys start to bind. We disassemble, clean, and lubricate with the right product, not WD-40 out of a can.
- Older Medeco cylinders with no working key on record. We see this constantly on ranch homes and tack sheds that changed hands over the years. The previous owner had a Medeco cylinder installed, the key vanished, and now nobody knows what’s pinned in there. We decode the cylinder and rekey it. No need to rip the whole lock out.
- Single-cylinder Medeco deadbolts with reachable glass. A Medeco deadbolt is only as strong as the door it’s mounted in. On older Mentone ranch homes with single-cylinder deadbolts and a sidelight or window within arm’s reach, the classic thumb-turn bypass is a real risk. We upgrade to double-cylinder where code allows, or add reinforcement to the frame and glass.
- Mismatched Medeco hardware across multiple buildings. A house key, a shed key, a tack room key, a gate key: it gets old fast. We rekey multiple Medeco cylinders on different buildings to a single restricted keyway so one key runs the whole property. More on that below.
Medeco Service in Mentone: What Local Conditions Mean for Your Equipment
Here’s the thing about Mentone that a generic Medeco page won’t tell you. This is a rural-residential foothill community with half-acre lots, horse properties, and older ranch homes. The buildings are spread out. A single property can have a mid-century house, a detached garage, a tack room, an arena gate, and maybe a second shed, each with its own lock and its own key. When a Medeco owner here wants a unified system, it’s not a simple rekey; it’s a multi-cylinder project that has to account for old single-cylinder deadbolts on the house, weathered gate hardware along Crafton Ave, and an outbuilding that probably still has the original builder’s lock from the 1970s. We plan for that. We bring the cylinders, pins, and key blanks to convert everything to one Medeco keyway in one trip, and we account for the fact that addresses out here aren’t always clearly posted on Mentone Blvd. We find you by the gate, not the number.
Medeco Models & Products We Service in Mentone
We service the Medeco Maxum deadbolt line, the Medeco Original high-security cylinder (often called the M3), and the Biaxial and m3 keyway systems. On mortise and rim cylinder applications, we handle Medeco Maxum variants as well. Our preference is genuine Medeco OEM cylinders, plugs, and key blanks. Those keep the restricted-keyway and key-control integrity intact. For older or discontinued Medeco lines, we’ll use quality aftermarket cylinders only where they match the security level of what’s coming out. We keep common Medeco key blanks and pin kits on the truck for fast Turnaround in Mentone and the surrounding foothills. When a cylinder can be decoded and rekeyed, we say so. When it’s better to replace the unit, we say that too. The goal isn’t selling you hardware; it’s a system that works.
Medeco Service Pricing in Mentone
Expect a Medeco rekey in Mentone to run between $65 and $130 per cylinder, depending on the keyway and the condition of the existing pins. A new Medeco Maxum deadbolt installed typically lands in the $280 to $450 range. Master key setup, where one key opens everything but individual keys can be restricted, is a bigger project: $350 and up depending on how many cylinders are involved and whether they’re existing Medeco or new hardware. What drives the price in Mentone is usually the number of buildings and the distance between them. We quote the full price on the phone before we dispatch, and that’s the price on the invoice. No call-out surcharge added at the door. Call (866) 497-9415 for an exact number on your setup.

FAQs – Medeco Locksmith in Mentone
Yes, if you are the registered key-control holder, we can cut a replacement Medeco key. If the key-control card is lost or you bought the property and the original paperwork never transferred, the key may not be duplicable under Medeco’s system. In that case, we decode the cylinder and rekey it so you have a fresh, working key-way and new keys in hand. It’s usually the faster path anyway. Call (866) 497-9415 and we’ll run you through what your specific lock needs.
Heat and dust. Mentone’s inland summers are brutally dry, and the Santa Ana winds push fine grit into uncovered cylinders. The lubricant inside the pin chambers dries out, the pins start to drag, and the key binds. It’s not a defect in the Medeco cylinder; it’s maintenance that hasn’t happened. We clean the cylinder, re-lubricate with a proper pin lubricant, and re-install. It’s a quick job, usually under 30 minutes per cylinder. If you’re noticing it now, call (866) 497-9415 and we’ll get it done before it gets worse.
Yes. This is one of the most common jobs we do in Mentone. We decode the existing Medeco cylinders across all your buildings, then repin them to a single Medeco keyway so one restricted key turns every lock on the property. If some outbuildings still have old, non-Medeco hardware, we can replace those with Medeco or Medeco-compatible cylinders during the same visit. One key, every building, same trip.
Depends on the condition of the cylinder and the housing. If the Medeco cylinder is mechanically sound, not too pitted, and the sidebar still engages cleanly, a rekey makes sense. It’s cheaper and keeps the restricted-keyway integrity. If the bolt is loose, the finish is gone on a weathered exterior door, or the Mortise cylinder has been drilled before, we’ll tell you straight: replacement is the better call. We don’t push replacements for the sake of it. Call (866) 497-9415 and we’ll tell you which way your lock should go.
Yes. A Medeco cylinder on a tack shed 200 feet from the house is still a Medeco cylinder, whether we’re working in Mentone or providing Medeco service in Calimesa. We bring everything in the truck, so we don’t need to run back or ask you to carry locks to the road. We’ll ask for your property’s gate code or driveway marker, because Mentone addresses off Mentone Blvd and Crafton Ave aren’t always obvious from the road. The job is the same work; the logistics just take a little longer. Call (866) 497-9415 and we’ll plan for your layout.
