Medeco Locksmith in Santa Rosa, CA | Preston Locksmith & Security
We provide independent Medeco locksmith service across Santa Rosa, CA, with same-day availability for most residential and our Commercial Locksmith in Santa Rosa calls. The thing that separates our Medeco work here from a generic locksmith shop is simple: we’ve been cutting Medeco keys and rebuilding their high-security cylinders in Sonoma County long enough to know how Santa Rosa’s specific climate and wildfire rebuilding patterns affect these locks. If you need a Medeco Maxum deadbolt rekeyed, a stuck M3 cylinder freed, or a restricted keyway reconfigured, call (409) 405-4485 and you’ll get a written price before we dispatch anyone.
We’re Medeco sales & service specialists, and we cover all of Santa Rosa service area territory, from Coffey Park to Bennett Valley to Rincon Valley. Kevin Yoon, our owner, cut his teeth on Medeco pin stacks years ago and still insists every technician in our shop do the same before they touch customer hardware.
Why Santa Rosa Residents Choose Us for Medeco Service
Medeco locks are a different animal from the Schlage or Kwikset deadbolt at the hardware store. The sidebar mechanism, the angled pin cuts, the restricted keyway: all of it requires specialized duplication equipment and someone who understands why a Medeco M3 cylinder won’t tolerate a key cut two thousandths of an inch off. Most general locksmiths in Sonoma County don’t stock Medeco-specific cutting tools or OEM pin kits. We do.
Kevin Yoon learned high-security lock work hands-on before he ever started this business, and he made sure every technician who works under the Preston name goes through the same training on Medeco, Mul-T-Lock, and Abloy systems. That’s why we’re the call Santa Rosa homeowners make when a contractor installs a new door and suddenly the Medeco deadbolt that worked fine for years won’t turn. We know what’s actually wrong, and we fix it without selling you a new lock you don’t need.
Every job includes The Relay Visibility Guarantee: a live trackable arrival time, before-and-after photos, and a written price confirmed before the first tool comes out of the bag.
Common Medeco Locksmith Problems We Solve in Santa Rosa
- Sidebar and pin wear from wildfire ash and dust. Santa Rosa’s fire seasons, including the Tubbs and Glass fires, left a lot of fine particulate matter in the air. That ash works its way into Medeco M3 and M4 cylinders and causes the sidebar to bind. You’ll notice the key needs jiggling to turn. We disassemble, clean, and replace worn pins with genuine Medeco OEM parts.
- Keyway corrosion from coastal fog and winter rain. West-side Santa Rosa neighborhoods get damp marine air rolling in off the coast, and over a few winters that moisture corrodes the keyway on a Medeco Maxum deadbolt. The key gets stiff. Sometimes it sticks entirely. We clean and lubricate the cylinder with the right products, and if the corrosion has pitted the keyway, we machine a replacement cylinder that preserves your same restricted key system.
- Bent or worn Medeco keys cut on inferior machines. We see this constantly in Santa Rosa: someone gets a spare Medeco key made at a kiosk or a big-box store, and the duplicate is off enough that the sidebar won’t fully align. That key might work a few times, then bind up mid-turn. We cut new restricted keys on our Medeco-specific duplication equipment and verify every one before it leaves the shop.
- Misaligned door strike or sagging hinges that bind the Medeco bolt. Santa Rosa’s expansive clay soils shift with seasonal moisture, and doors settle out of square. When the strike plate is off by even an eighth of an inch, a Medeco deadbolt bolt binds and feels like a lock failure. Often the lock itself is fine. We realign the strike, square the hinges, and the lock works like new.
- Mismatched hardware after wildfire rebuilds. Homes rebuilt after the Tubbs and Glass fires often ended up with mixed lock hardware: a Medeco deadbolt on the front door, a Kwikset on the back, maybe a Baldwin on the garage. Rekeying everything to one Medeco restricted keyway gives you a single key for every door and preserves the high-security investment you already made.
Medeco Service in Santa Rosa: What Local Conditions Mean for Your Equipment
Santa Rosa’s wildfire history left something most people don’t think about until their lock acts up: rebuilt and renovated homes across Coffey Park, Fountaingrove, and the hills off Mark West Springs Road got new doors and hardware installed by contractors who weren’t Medeco specialists. We regularly see homes where a perfectly good Medeco M3 deadbolt was removed during a door replacement and reinstalled without proper strike alignment, or where new Schlage hardware was dropped in next to an existing Medeco restricted system. The homeowner is left with two different keyways, a deadbolt that grinds when they turn the key, and no idea which key goes where. That’s a fix we’ve done hundreds of times. We Santa Rosa Rekey Locks to one Medeco restricted keyway, realign the strikes, cut fresh restricted keys, and leave the house with a single ring that operates every door. We were called to a home in the Coffey Park neighborhood where a Medeco M3 deadbolt had become nearly impossible to turn after the homeowner’s contractor installed a new front door. Our technician found the strike plate misaligned by an eighth of an inch, binding the bolt; we adjusted the strike, cleaned and lubricated the sidebar, and cut two new restricted keys on our Medeco-specific machine so the family had spares that actually worked.
Medeco Models & Products We Service in Santa Rosa
We work on the full Medeco high-security range: the original Medeco Biaxial cylinders, the M3 and M4 high-security cylinders, the Maxum deadbolt line, and KeyMark restricted keyway systems. For any restoration work, we use genuine Medeco OEM pins, springs, and sidebar components. Aftermarket cylinders only come into play for lower-security applications where the customer explicitly wants a budget option. We keep a stocked inventory of Medeco parts in our Santa Rosa service vehicles, which means most repair and rekey jobs don’t wait on parts to ship. On the rare occasion we need something outside stock, we tell you upfront and give you a firm timeline before you commit.
Medeco Service Pricing in Santa Rosa
Rekeying a standard Medeco cylinder to a new key typically runs $25 to $45 per cylinder. Cutting a new restricted Medeco key from your existing key runs $10 to $25 per key, depending on the keyway type. Repair work, like cleaning a corroded cylinder or replacing worn pins, generally lands between $75 and $180. New Medeco Maxum deadbolt supply and installation sits in the $180 to $340 range depending on finish and keyway options. What drives the final number is the condition of your existing hardware and whether you need new keys cut. A free estimate from us means an actual number, not a range that swells later. Call (409) 405-4485, tell us what you’re dealing with, and we’ll quote the real price before anyone gets in the truck. Real price on the phone. Same price at the door. That’s it.

FAQs – Medeco Locksmith in Santa Rosa
Yes, in most cases, but we need to verify you’re authorized to have keys cut for that lock. If you own the property and can demonstrate that, we can cut Medeco M3 keys on our specialized duplication equipment. The key control card helps speed things up, but its absence isn’t usually a dealbreaker. Call (409) 405-4485 and we’ll tell you exactly what you need to show us.
Gritty operation in Santa Rosa almost always means fine particulate matter inside the cylinder. Wildfire ash, dry summer dust, and road grit all find their way into the keyway and eventually into the pin chambers. A Medeco cylinder lives or dies by precision tolerance, and grit scores the pins over time. We disassemble the cylinder, ultrasonic clean the components, replace any worn pins with Medeco OEM parts, and re-lubricate. The lock should turn smoothly again. If it doesn’t, we’ll tell you honestly whether repair or replacement makes more sense.
Probably not. When a Medeco key turns fully but the door won’t open, the usual culprit in Santa Rosa is a misaligned strike plate or a door frame that’s settled out of square. Our expansive clay soils shift with seasonal moisture, and a door frame that moved even slightly can bind the deadbolt. We start by checking the strike alignment and hinge geometry before touching the lock. Nine times out of ten, that’s the fix. Call us at (409) 405-4485 and describe what you’re seeing. We’ll give you an honest read over the phone and a fair price for the repair.
Yes. We design and cut master key systems for Medeco restricted keyways regularly. You get a hierarchy: each employee key opens only what it should, and your master key opens everything. We map the system, cut the keys on our Medeco-specific equipment, and deliver a written record of which key operates which door. This is scheduled work with a written scope and a flat per-lock price, not a dispatch-and-see job. Call (409) 405-4485 for a written quote.
We stock common Medeco M3 and M4 cylinders, Maxum deadbolts, and OEM pin kits in our Santa Rosa service vehicles. Most replacement work happens same-day. If you need a cylinder in a less common keyway or an unusual finish, we can usually get it within a few days and we’ll tell you the timeline before you pay for anything.
