We provide independent Medeco locksmith service across Irvine, including Woodbridge, Turtle Rock, and the Irvine Spectrum area. The one thing that makes our Medeco work here different is this: Irvine’s HOAs and village design standards dictate finish and hardware choices, so a Medeco upgrade isn’t just about security, it’s about passing architectural review. If you’ve got a Medeco deadbolt that won’t throw, a restricted keyway that needs rekeying, or a master key system for a condo building, call us at (866) 497-9415. We’re Medeco sales & service specialists who know the hardware and the local rules.
Why Irvine Residents Choose Us for Medeco Service
We work on Medeco cylinders daily. Not occasionally. Not “we’ve seen one before.” The M3, the Biaxial, the Maxum deadbolt, the interchangeable core, the rim and mortise cylinders on commercial doors. High-security hardware like Medeco and Abloy requires a locksmith who knows it cold, and that’s us. We carry genuine Medeco cylinders, keys, and sidebar components, because those parts are what the security rating depends on. Where OEM adds cost without benefit, like strikes and reinforcement plates, we’ll tell you and use quality aftermarket hardware instead.
Gil Tanner, our owner, learned the trade at Riverside City College and has spent three decades working locks across Southern California. His standard is simple: explain what we did and why. If a Medeco cylinder is worn but the sidebar and pins are still serviceable, we rebuild it rather than sell you a replacement you don’t need. And we’ll always tell you which is the right call for your situation. Serving our Irvine service area means we’ve rekeyed hundreds of Medeco locks in the villages, and we understand the finish requirements those HOAs enforce.

Common Medeco Locksmith Problems We Solve in Irvine
- Restricted keyway keys that can’t be duplicated at a big-box store. Medeco restricted keyways require a carded key and an authorized cutter, which is great for security and miserable when you lose the only remaining key. In Irvine’s condo and rental turnovers, we regularly see owners facing a full cylinder replacement because the carded key is gone. We can rekey the cylinder to a new restricted set or discuss a non-restricted Medeco option after assessing how much control you actually need.
- A deadbolt that reads as “broken” but isn’t. Inland Orange County heat and Santa Ana wind cycles swell and shrink door slabs and jambs. The Medeco Maxum’s hardened bolt drags or the strike misaligns, and the lock feels like it’s failing. Most of the time, the cylinder is fine. The door has shifted seasonally. We reset the strike, adjust the backing screws, and you’re back in business without a new $300 deadbolt.
- Corroded exterior finishes and gummed internals. In the west-side Irvine villages, marine air moves in and accelerates corrosion on exterior hardware. Over years, that corrosion gums the internal pins and sidebar inside a Medeco cylinder. Medeco’s tolerances are tight, so a dry or contaminated cylinder punishes you faster than builder-grade hardware would. We disassemble, clean, lubricate with the right product, and rebuild when the internals are salvageable.
- Loose backing screws and misaligned cams. Original installations in older villages often paired a Medeco upgrade with door prep that was never re-checked. Backing screws loosen, the cylinder works itself out of alignment with the cam, and the key starts fighting you. This is one of the most common things we see in Woodbridge and Turtle Rock. It’s a ten-minute fix on site, not a lock replacement.
- Master key system confusion. Condo buildings and small commercial properties in Irvine often have a Medeco master key system that’s been patched together over years of turnovers. Sub-master keys stop working for certain units, no one remembers which doors were rekeyed when. We map the existing system, identify what’s drifted, and restore it or build a clean rekey schedule so every key works exactly where it should.
Medeco Service in Irvine: What Local Conditions Mean for Your Equipment
Irvine’s village HOAs and the Irvine Company design standards frequently dictate the approved exterior hardware finish. A Medeco upgrade here often has to match the community’s specified finish and door prep rather than whatever high-security line happens to be on the truck. In the older villages like Woodbridge and Turtle Rock, original builder-grade brass and Kwikset knobs from the 1970s and 80s are now failing en masse. Many HOAs still require matching the community’s approved finish, so what starts as a simple rekey can turn into a hardware-sourcing job. A homeowner calls us for a seized Medeco Maxum deadbolt, and we end up sourcing a replacement knob in the exact antique brass finish the HOA approved in 1983 so the door passes inspection. That’s not a generic Medeco problem or a generic Irvine problem. It’s what happens when you combine a high-security lock line with one of the most design-regulated housing markets in the country. We’ve handled it enough that we know which finishes the villages in ZIP codes 92606, 92612, 92614, and 92616 typically require, and we stock or can source accordingly.
Medeco Models & Products We Service in Irvine
We service the full residential and commercial Medeco range. The M3 cylinder and interchangeable core, which we see most often in Irvine condo and commercial doors. The Maxum deadbolt, the line most common in single-family homes here. The Medeco Original, also called Biaxial, which still shows up in older houses and some small commercial properties. And Medeco high-security rim and mortise cylinders on commercial doors. We also handle keyed-alike and master key configurations across those lines. We use genuine Medeco cylinders, keys, and sidebar components wherever the security rating depends on them. We do not install knockoff Medeco-labeled cylinders or aftermarket key blanks passed off as OEM. Our parts approach is honest: OEM where it matters, quality aftermarket hardware where OEM just adds cost. We keep common Medeco cylinders and key blanks stocked, and anything we don’t have we can typically source within a day or two for Irvine jobs.
Medeco Service Pricing in Irvine
Here’s what you can expect to pay for Medeco work in Irvine. A service call and rekey of an existing Medeco cylinder runs roughly $95 to $190 depending on how many cylinders and whether we’re cutting new keys. Replacing a single Medeco Maxum deadbolt typically lands between $180 and $340 including the cylinder and installation. Media M3 or Biaxial cylinder replacement runs $120 to $250 per cylinder. A master key system setup for a small condo or commercial building starts around $300 to $600 depending on the number of doors and key levels. If you’ve lost a carded restricted key and need a full cylinder replacement, add $60 to $120 per cylinder on top of the cylinder cost. These are honest ranges, not teasers. The full price is quoted on the phone before anyone is dispatched, and that’s the price on your invoice. No call-out surcharge added on arrival. Call (866) 497-9415 for an exact quote, and we’ll walk you through what your specific job will cost before we schedule anything.

FAQs – Medeco Locksmith in Irvine
Only if you have the key card that Medeco issues with restricted keyways. Without that card, no independent locksmith can legally duplicate a restricted Medeco key. If you’ve lost the carded key and need a new one, we’ll assess whether a cylinder rekey to a new restricted set makes sense, or whether a non-restricted Medeco keyway would serve your situation. Call (866) 497-9415 and we’ll walk you through your options.
Usually not. In Irvine, summer heat and Santa Ana dry air swell door slabs and jambs, which misaligns the strike and makes the Medeco Maxum’s hardened bolt drag. The lock reads as failed, but the cylinder is often perfectly fine. We’ll come out, check the door’s alignment, reset the strike, and rekey or rebuild the cylinder only if the internals actually need it.
Most Irvine village HOAs don’t mandate a lock brand, but they do mandate the finish and sometimes the hardware profile. A Medeco deadbolt in polished brass won’t pass review in a community that requires satin nickel or oil-rubbed bronze. Before you buy or install, we check your village’s approved finish list and source the right hardware. It saves you a refused inspection and a redo.
Rekeying changes the internal pins and sidebar so the old key no longer works and a new key does. The cylinder stays in the door. Replacement means the entire cylinder or deadbolt is removed and a new one installed. In Irvine, rekeying is usually the smarter move after a tenant turnover or a lost key, as long as the cylinder internals aren’t worn out. We’re honest about which one your situation needs. Call (866) 497-9415 and we’ll give you a straight assessment.
Yes. We design and install Medeco master key systems for Irvine condos, HOA common areas, and small commercial buildings. We map every door, assign key levels, and hand you a clean schedule so you know exactly which key opens which door. A written scope and flat per-lock pricing before we start.
