Medeco Locksmith in Fontana, CA | Dunmore Locksmith
We provide independent Medeco specialists across Fontana’s residential neighborhoods and warehouse corridor, with same-day appointments available most days. The one thing that makes our Medeco work here different is how often we’re aligning deadbolts on heat-warped 1950s ranch doors in the morning and rekeying restricted keyways for fleet yards off Slover Avenue by afternoon. That’s Fontana’s split personality, and we’ve been handling both sides since 2007. Call (910) 714-4287 for a free estimate – we’ll quote your exact price before anyone is dispatched.
Why Fontana Residents Choose Us for Medeco Service
Perry Osgood, who runs Dunmore Locksmith, grew up in LA’s Palms neighborhood watching his uncle re-key apartment buildings. He learned early that this trade runs on trust, not torque. After locksmithing coursework at Los Angeles Trade-Technical College and two decades working locks across the city, he built Dunmore on a rule he still enforces: every technician we send is someone Perry would send to his own mother’s house.
That matters with Medeco. These aren’t hardware-store locks. The restricted keyways, rotating-pin ARX platforms, and Biaxial pick-resistant cylinders are precision equipment – and Fontana’s inland valley conditions punish precision equipment harder than coastal cities 40 miles west. We’ve serviced Medeco hardware on everything from original ranch-home doors near old downtown Fontana to fleet-padlock systems at distribution centers along the I-10 corridor. We stock genuine Medeco OEM cylinders, pins, and restricted key blanks for Biaxial, ARX, and Maxum platforms. We won’t substitute generic parts on a Medeco door because the tolerances are the entire security story.
Every job carries our 365-Day Done Right Promise: written guarantee, and if the repair fails, we return at no charge. You’ll know your technician’s name and see their photo before they arrive. The price goes in writing before any work starts – no exceptions.
Common Medeco Locksmith Problems We Solve in Fontana
- Heat-warped door frames jamming Medeco Maxum deadbolts. Fontana’s 105°F+ summer highs swell wood and composite door slabs, pushing deadbolts out of strikeplate alignment. The cylinder turns freely but the bolt won’t throw fully or binds hard. We realign or reinforce strikes and replace worn bolt bodies with correct OEM Medeco parts – not generic assemblies that compromise your restricted keyway.
- Dry heat and valley dust seizing Biaxial and ARX rotating pins. Fine Inland Empire particulate infiltrates exterior cylinders, and 105-degree days bake out factory lubricant. The pins grind instead of rotating. We disassemble, clean with solvent, and relubricate with dry-film products formulated for high-dust, high-heat environments – standard procedure on warehouse and retail doors along the Slover/Cherry logistics belt.
- High-security cylinders outliving cheap deadbolt bodies on aging tract homes. Fontana’s 1980s – 2000s stucco developments installed contractor-grade hardware that’s now failing while the Medeco cylinder itself is still sound. We see this in neighborhoods with high renter turnover – the restricted keyway survives, but the bolt assembly is misaligned, corroded, or worn past function. We replace the body with genuine Medeco OEM, keeping your existing key and keyway intact.
- Fleet and semi-truck Medeco padlocks failing from road exposure. The logistics corridor running along Slover and Cherry generates enough commercial traffic that our vans carry Freightliner and Kenworth key blanks as standard inventory. Medeco kingpin locks and trailer padlocks take chemical spray, salt, and weather exposure that seizes cylinders or corrodes shackles. We service or replace the cylinder rather than duplicating a key for a lock that’s no longer secure.
- Restricted keyway systems needing expansion or rekeying after personnel changes. Fontana’s warehouse and distribution density means master key systems change hands frequently – new fleet managers, new tenants, new security protocols. We rekey Biaxial and ARX cylinders to new combinations, add or remove master key levels, and cut new restricted keys from blanks we stock locally. No waiting for factory shipment.
Medeco Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s warehouse belt along Slover and Cherry has enough semi-truck and fleet traffic that experienced locksmiths here keep Freightliner and Kenworth key blanks on the van as standard inventory. That’s not true in Upland. It’s not true in Redlands. And it shapes how Medeco in San Bernardino and nearby cities differs from how we handle it here in a way no generic page captures.
Our Medeco master-key and access-control jobs in Fontana often start with a fleet manager who needs one restricted keyway across dozens of trailers, yard gates, and warehouse doors – not a single office lock. The ARX rotating-pin platform and Biaxial restricted keyways are built for exactly this: key control so tight that unauthorized duplication is functionally impossible, even across a large facility with multiple access levels. We’ve installed Medeco master key systems where the general manager carries a grand master, shift supervisors carry area masters, and individual drivers carry change keys that open only their assigned trailers. When someone quits or a contract ends, we rekey the affected cylinders same-day from blanks already in our Fontana inventory. The logistics density that makes Fontana unique also makes speed essential – a yard full of idle trailers because of a key-control breach costs more than any locksmith invoice.
This same corridor’s dust and dry heat mean those exterior cylinders need more frequent service than indoor office installations. We account for that in our maintenance recommendations.
Medeco Models & Products We Service in Fontana
We handle the full Medeco mechanical line with OEM-compatible parts stocked for Fontana turnaround:
- Medeco Maxum deadbolt series – residential high-security, often installed on upgraded Fontana ranch-home doors or as replacement for failed contractor-grade hardware in tract developments.
- Medeco Biaxial and Biaxial Plus cylinders – restricted keyway systems for commercial master key applications; we stock blanks and pins for same-day rekeying.
- Medeco ARX rotating-pin deadbolts and knobs – the current flagship for high-traffic commercial doors; we service pin assemblies and replace worn cylinders with factory-matched units.
- Medeco Classic / Original series – still in service on older Fontana commercial doors; we maintain these with correct vintage-compatible parts rather than forcing incompatible retrofits.
We are an independent locksmith, not a Medeco dealer or authorized service center. Our expertise comes from years of field service, not factory certification. When a cylinder’s body or pins are worn past reliable function, we tell you honestly: replacement with the correct OEM part preserves your security rating. A cheap rekey on a damaged cylinder defeats the purpose of buying Medeco in the first place.
Medeco Service Pricing in Fontana
Rekeying a standard Medeco Biaxial or Classic cylinder on a residential door in Fontana typically runs $145 – $220. Replacing a Medeco Maxum deadbolt body while retaining the existing cylinder and key ranges $180 – $280. Commercial master key rekeying with restricted blanks starts around $95 per cylinder for straightforward pin changes, scaling with hierarchy complexity and quantity. Fleet padlock cylinder service or replacement runs $75 – $150 per unit depending on shackle condition and access difficulty.
What drives cost: cylinder type (ARX rotating-pin assemblies take longer to service than standard pin-tumbler), whether we need to extract a broken key or drill a seized core, and whether the door frame needs strike realignment or reinforcement to match. Every estimate is free. The full price is quoted on the phone before anyone is dispatched, and that price matches the invoice – no call-out surcharge added on arrival, no after-the-fact totals. Call (910) 714-4287 for your exact quote.

FAQs – Medeco Locksmith in Fontana
No – not without drilling or destroying the cylinder. Medeco’s restricted keyway design requires the existing key to read the pin depths before we can cut a new working key or rekey to a new combination. If your key is lost, we replace the cylinder with a new OEM unit and key it to fresh restricted blanks we stock. Call (910) 714-4287 – we’ll confirm your model and quote the replacement before dispatching.
Wood and composite door frames swell in Fontana’s 105°F+ heat, pushing the strikeplate out of alignment with the bolt. The Medeco cylinder turns; the bolt just has nowhere to go. We realign or relocate the strike, and sometimes reinforce the frame to prevent recurrence. Dry valley dust also degrades lubricant inside the cylinder – we clean and relubricate with dry-film products formulated for this climate. Call (910) 714-4287 and we’ll schedule before the next heat wave.
Yes – we stock Biaxial and ARX restricted blanks for same-day cutting and rekeying. Fleet yards and distribution centers along the Slover/Cherry corridor are exactly the Fontana locations where we’ve built master key systems with multiple hierarchy levels. We cut on-site from existing codes or create new combinations as needed. Call (910) 714-4287 to confirm your keyway profile.
Yes, if you want key control – the ability to know exactly who has a working key and prevent unauthorized duplication. Many Fontana tract homes in high-turnover neighborhoods have been rekeyed multiple times with standard hardware; anyone with an old key from a previous tenant, contractor, or realtor still has access. A Medeco restricted keyway ends that. We often install Maxum deadbolts on these homes, sometimes reusing an existing Medeco cylinder if the bolt body is what’s actually failing. Call (910) 714-4287 for a free assessment of your current hardware.
