We service, rekey, and install Medeco high-security locks across Rialto’s two distinct housing zones: the 1950s-1970s tract homes of 92376 and the newer 92377 subdivisions north of the 210. What makes our Medeco work different here is simple. We actually know what happens when a Medeco Maxum cylinder gets fitted into a 50-year-old builder-grade knob on a heat-warped door off Foothill Blvd. That’s not a hypothetical for us. It’s a typical Tuesday.
Our team handles Medeco sales & service across Maxum, M3, Biaxial, and KeyMark systems, and we’re an independent shop, not a manufacturer-authorized dealer. For 25 years, the difference has shown up in how we diagnose and pin these cylinders, not in what we claim on a website. Call (855) 791-2710 for Medeco work in Rialto, and you’ll get an honest answer about your hardware before anyone rolls a truck.
Why Rialto Residents Choose Us for Medeco Service
Medeco locks run on tighter tolerances than the Schlage or Kwikset gear most homeowners have handled. The sidebar, the pin angles, the restricted keyway. Get any of it slightly wrong and you’ve got a lock that works today and fails next August. We’ve spent years fixing Medeco cylinders that other shops pinned poorly or, worse, swapped for aftermarket internals that wore out within a season.
Noel Tarkanian, our owner and lead technician, grew up watching his uncle rekey apartment units in Glendale, which means he learned early that a cylinder only works as well as the door it’s mounted in. That matters in Rialto specifically, where doors move with the seasons, just as they do for our Medeco repair in Muscoy calls. We carry genuine Medeco OEM cylinders, pin kits, and restricted blanks for Maxum, M3, and Biaxial. We repair and re-pin existing hardware whenever the cylinder body is sound. Replacement only gets recommended when the sidebar or pin chambers are worn past reliable service, a call we make conservatively and explain clearly.
We work the lock you already have first. That’s the whole approach. If you’re in our Rialto service area, you get that evaluation, not a sales pitch.

Common Medeco Locksmith Problems We Solve in Rialto
- Heat-warped door slabs that bind the deadbolt. Triple-digit Inland Empire summers bake doors until the frame shifts. A Medeco deadbolt that turned smoothly in March starts binding in July. The fix is usually strike adjustment, not cylinder replacement, but it takes a tech who checks the door before touching the lock.
- Santa Ana dust and grit in the sidebar cylinder. The dusty winds that sweep through the 92376 tracts off Foothill Blvd and Riverside Ave leave fine grit in exterior locks. Medeco sidebar cylinders are precision machines. Grit makes key rotation stiff and accelerates pin wear. We clean, lubricate with the right dry film, and re-pin when wear has already set in.
- Medeco cylinders mounted in worn 1960s-70s builder hardware. Those original knob locks in older Rialto homes have oval pin chambers after five decades. Fit a Medeco cylinder into that and the key only catches if you lift the door while turning. We see this constantly in the 92376 core. The fix sometimes means re-pinning, sometimes a full hardware swap.
- Builder-installed Medeco deadbolts in 92377 subdivisions with shallow preps. Newer Rialto construction moves fast. We regularly find Medeco deadbolts that were never properly seated because the door prep was too shallow or the backset non-standard. A simple rekey turns into re-boring and strike reinforcement once we open it up.
- Lost restricted keys with no key control card. Most Medeco owners in Rialto never receive the card, or it’s gone. That doesn’t stop us. We verify ownership, then rekey the cylinder to a new restricted keyway so old keys stop working. More on that below.
Medeco Service in Rialto: What Local Conditions Mean for Your Equipment
Rialto is a working-class Inland Empire crossroads, and the locksmith work here reflects that. The 92376 core still has original 1960s-70s builder hardware on front doors and gates. Those worn pin chambers and sagging jambs are a Rialto-specific pattern you won’t find in a newer master-planned city. In the 92377 subdivisions pushed toward the foothills, builder-installed deadbolts are common, but so are heat-warped slabs and shallow door preps. A routine Medeco rekey in 92376 often turns into a full cylinder or hardware swap once we see what’s underneath. In 92377, the opposite happens: newer hardware, but poor installation. Either way, a Medeco lock is only as good as the door and frame around it, and in Rialto, both need attention before the cylinder itself does.
We saw this on a rekey call off Foothill Blvd in the 92376 core. A Medeco Maxum cylinder had been fitted into a 1970s builder-grade knob lock whose pin chambers were worn oval. The key only turned if you lifted the door. We re-pinned the Maxum, reinforced the strike, adjusted the sagging jamb so the deadbolt lined up cleanly, then keyed the gate to the same restricted keyway. A different call, in a 92377 subdivision off Riverside Ave, involved a builder-installed Medeco M3 deadbolt on a heat-warped door. That one needed a fresh bore and strike plate before the cylinder would seat at all. Both jobs ended with the same result: a Medeco lock that actually functions like one.
Medeco Models & Products We Service in Rialto
We stock and service the full range of Medeco residential and light-commercial hardware in Rialto and offer Medeco service in Bloomington as well.
- Medeco Maxum: The workhorse deadbolt. We keep Maxum cylinders, pin kits, and restricted blanks on hand for rekeys and repairs in 92376 and 92377.
- Medeco M3: The current-generation high-security platform, common in newer 92377 subdivisions. We service M3 deadbolts and handle rekeying to M3 restricted keyways.
- Medeco Biaxial: The older standard, still running in many Rialto rental properties and commercial storefronts along Riverside Ave and Foothill Blvd. We repair and re-pin Biaxial cylinders when the body is sound.
- Medeco KeyMark: The key-control system often spec’d on light-commercial and multi-unit properties. We cut and manage KeyMark keys for property owners and managers.
When it comes to parts, we use genuine Medeco OEM for anything that touches the pin chambers, sidebar, or keyway. Strikes and reinforcement plates we source based on the door’s existing prep. If a door needs a strike that fits the old mortise, that’s what goes on. We don’t force a modern plate into a 1960s frame because it happens to be in the van. The right hardware, fitted right, that’s all security actually is.
Medeco Service Pricing in Rialto
Medeco work in Rialto runs higher than standard Schlage or Kwikset service, and that’s honest. The parts cost more, the pinning takes longer, and the tolerances are tighter. Here’s what to expect:
- Medeco rekey (standard single cylinder): $45-$95, depending on keyway and cylinder condition.
- Medeco rekey with lost key control card: $65-$120, including new restricted keys.
- Medeco cylinder replacement (parts and labor): $90-$180 for standard Maxum or Biaxial, higher for M3 on non-standard prep.
- Full Medeco deadbolt install (new door prep): $150-$280, including new bore, strike reinforcement, and hardware.
- Emergency Medeco lockout service: $75-$150, depending on time of day and whether the cylinder needs re-pinning after entry.
The full price gets quoted on the phone before anyone is dispatched, and that’s the price on the invoice when we leave. No call-out surcharge added on arrival. In this trade, too many Rialto homeowners have been burned by a low “starting at” number that triples by the time the tech packs up. That’s not how we work. Call (855) 791-2710 for an exact quote. Estimates are free, and we’ll tell you whether the cylinder is worth saving before we touch it.

FAQs – Medeco Locksmith in Rialto
Yes. We rekey Medeco cylinders in Rialto without the card all the time. We verify you have lawful access to the property whether that’s a deed, lease, or utility bill with a matching address, then we re-pin the cylinder to a new restricted keyway and cut new keys. The old keys stop working immediately. This works for Maxum, M3, Biaxial, and KeyMark. Call (855) 791-2710 for a quote, and bring whatever proof of address you have.
Heat. Rialto regularly hits triple digits from June through September, and door slabs expand and warp. The strike plate shifts a fraction of an inch and the Medeco bolt, which has tighter tolerances than a standard deadbolt, starts binding against it. It’s rarely the cylinder. We adjust the strike and, if needed, plane the edge so the bolt throws cleanly. If the door’s warped beyond adjustment, we’ll tell you that too. Call us before you force the key, forcing a Medeco key through a bound cylinder is how you break one.
Constantly. The older 92376 tracts around Foothill Blvd and Riverside Ave still have original builder-grade knob locks and single-cylinder deadbolts, and many of those have had Medeco cylinders swapped in over the years. The pin chambers in those 50-year-old locks are often worn oval, which means the Medeco cylinder can’t seat properly and the key only catches if you lift the door. We re-pin what’s serviceable and recommend replacement only when the body is truly done. That’s a judgment call we make with you standing there, not something we decide from the van.
Yes. The 92377 homes north of Base Line Road are newer, but we regularly find builder-installed deadbolts with shallow preps or non-standard backsets. A Medeco M3 deadbolt needs more depth than a standard Kwikset, so sometimes we have to deepen the bore and reinforce the strike. We’ll bring the right jig and do it on the first visit. No call-back dance. If you want Medeco on a newer Rialto door, call (855) 791-2710 and we’ll tell you what the prep needs.
Biaxial is the older standard and still common in Rialto rentals. Maxum is the newer deadbolt line with a stronger bolt and better drill resistance. M3 is the current-generation high-security platform with the most restricted keyway options. For a Rialto rental property, we usually recommend Maxum or M3 depending on tenant turnover and how many copies of the key already float around. The tighter the key control, the fewer rekeys you’ll pay for down the road. Call our office for a recommendation based on your specific property.
