We provide independent Medeco locksmith service across Novato, from the 1950s tracts near downtown to the gated hillside properties off the 94947 ridges. What makes our Medeco work different here is that we handle both failure modes this city throws at high-security hardware: sun-baked cylinders on exposed ridgelines and rain-swollen doors on the flatlands that bind deadbolts every winter. We rekey, rebuild, and repair Medeco equipment—from Novato to Medeco service in Woodacre—without pushing you toward a new system when the existing one can be saved. Call Cypress Lock & Key at (877) 265-4385 for a straight diagnosis and an upfront estimate.
Why Novato Residents Choose Us for Medeco Service
Medeco’s restricted keyways and rotating-pin-tumbler platform are not something every locksmith sees weekly. We do. Our bench has worked through Medeco Maxum deadbolts, M3 and M4 cylinders, KeyMark retrofits, and commercial rim and mortise cylinders on enough Novato properties to know exactly which internal components wear first and which ones get gummed with old lubricant after a few hot inland summers. Because we’re an independent shop, not a manufacturer-authorized dealer, we can rebuild a sound cylinder with genuine Medeco pins, springs, and sidebars instead of telling you the whole lock needs replacing. Noel Carver, our owner and lead locksmith, has been running calls in this part of Marin for close to two decades, and the approach on every Medeco job is the same: identify what’s actually failing, fix that, leave the rest alone. That’s the difference between a parts-swapper and a locksmith. For broader context on our Medeco work, see our Medeco sales & service page.

Common Medeco Locksmith Problems We Solve in Novato
- Key binds in an otherwise healthy cylinder. Sun and heat on Novato’s inland ridges oxidize exterior Medeco cylinders faster than you’d see in Sausalito or Mill Valley. The key starts binding even when the pin stack is fine because the housing has stiffened and the rotating pins no longer turn freely. We disassemble, clean, re-lubricate with the right product, and reassemble.
- Mushy or jiggly key feel. Medeco rotating pins and sidebar components are precise. When they wear or pick up old lubricant residue, a key that used to turn crisp starts feeling vague. That’s a service call, not a lock replacement. We install fresh springs and sidebars as needed and restore the original feel.
- Deadbolt won’t throw on a flatland tract door. Winter rain swells the wooden doors on Novato’s 1950s-70s housing stock, pushing the misalignment into the Medeco deadbolt throw. The hardened bolt jams against the strike. The fix is often a realignment plus a strike adjustment, not new hardware.
- Lost or stolen restricted keys with no security card. This happens more than people expect. The original installer is gone, the card is missing, and the homeowner is stuck. Medeco restricted blanks can’t be duplicated at a hardware store. We do a controlled rekey, issue new keys, and document the new key control setup so it doesn’t happen again.
- Shared driveway gate hardware that’s seized. Hilltop and canyon properties off the 94947 ridges often run one gate for several homes. When that gate hardware oxidizes and the Medeco cylinder on the house binds in the same season, you need someone who can address both without compromising the restricted keyway. That’s a two-part job we’ve done repeatedly.
Medeco Service in Novato: What Local Conditions Mean for Your Equipment
Novato sits in a warmer, sunnier inland pocket of Marin, shielded from the fog that keeps Sausalito and Mill Valley cooler and damp. That means exterior Medeco cylinders and gate hardware here bake and oxidize harder than anywhere else in the county. At the same time, the winter rains swell the wooden doors on those flatland postwar tracts along the 101 corridor, throwing deadbolts out of alignment from moisture, not heat. The same Medeco deadbolt can fail two entirely different ways within one city depending on whether it’s mounted on a sun-exposed ridgeline home off the 94947 hills or a 1960s rancher near downtown. No neighboring Marin city has this split. When we get a stiff Medeco key in Novato, we don’t assume wear. We ask where the property sits and whether the door faces the afternoon sun or the winter rain. Know your hardware, know your options – the rest is just turning a key.
Medeco Models & Products We Service in Novato
We service the Medeco Maxum deadbolt in both standard and dual-cylinder configurations, M3 and M4 cylinders carrying the Biaxial and KeyMark lineage, Maxum rim and mortise cylinders on commercial doors, and KeyMark retrofit cylinders where an older Medeco system has been upgraded. Our parts approach is simple: genuine Medeco pins, springs, sidebars, and restricted blanks wherever they’re available, and quality aftermarket parts only for non-security-critical items like strikes and reinforcement plates. We stock common Medeco components locally so most Novato service calls finish in one visit. If your Medeco hardware is on a door that’s seen better decades, we’ll tell you honestly whether a rebuild makes sense or whether the housing itself is compromised and replacement is the smarter call.
Medeco Service Pricing in Novato
A Medeco cylinder rebuild or rekey in Novato typically runs $85 to $185 depending on the cylinder type and whether new restricted keys are needed. A full Medeco Maxum deadbolt installed on a prepared door generally lands between $240 and $380 including hardware. What drives the cost on hillside or shared-gate properties is the extra coordination: matching gate hardware, working with multiple households, and sometimes dealing with an existing cylinder that’s been exposed to years of inland sun. Every estimate is free, and the price we give you on the phone is the price on the invoice. No dispatch fee added when the tech arrives. Call (877) 265-4385 and we’ll walk through what you have, what it needs, and what it costs before anyone gets in a truck.

FAQs – Medeco Locksmith in Novato
Yes. The security card controls key duplication, not the ability to rekey the cylinder itself. We can decode the existing pins, rebuild the cylinder, cut new restricted keys, and issue a new card so you control future duplicates. Call (877) 265-4385 and we’ll confirm what’s on your specific lock.
The most common cause on Novato’s flatland tracts is rain-swollen wooden doors shifting the deadbolt out of alignment with the strike. The Medeco bolt itself is hardened, so it binds instead of flexing. A strike realignment and door adjustment usually fixes the seasonal stiffness without touching the cylinder.
Almost always yes, especially off the 94947 ridges where one gate serves multiple homes. The restricted keyway gives you control over who can duplicate keys, which matters when several households share access infrastructure. We’d rebuild and re-lubricate the cylinder before ever recommending replacement. Call (877) 265-4385 for a straight read on what your specific setup needs.
Yes, and it’s one of the most common upgrades on Novato’s 1950s-70s tract homes that still carry original Kwikset-style hardware. We bore for the full Medeco deadbolt, install with a reinforced strike, and key the deadbolt to a restricted keyway. The old knobset can stay or be replaced depending on what you want.
In Novato’s inland heat, the cylinder usually needs cleaning and re-lubrication before it needs replacement. We’ll inspect the rotating pins, sidebar, and housing. If the housing isn’t cracked or compromised, a rebuild with genuine Medeco parts restores the original action for less than a new lock. Call (877) 265-4385 for an exact quote – estimates are free.
