We provide independent Medeco cylinder rebuilds, re-pinning, and restricted-key rekeying across Black Point-Green Point (94998) for homeowners and off-site property managers. The work that makes our Medeco service different here is the salt-air rebuild: canal-side and boat-access cylinders seize faster than front-door locks, and we rebuild pin stacks with genuine Medeco internals rather than swapping in a weaker aftermarket core. Call (833) 589-8078 for a free estimate, and you’ll get a phone quote that matches the invoice.
Why Black Point-Green Point Residents Choose Us for Medeco Service
Before Roland Vásquez ever touched a Medeco sidebar, he spent his teenage years learning lock mechanics at his uncle’s hardware shop near Mission Street, then studied the trade formally at City College of San Francisco. That training never left. He still approaches any high-security cylinder the same way: diagnose the pin stack first, replace only what is worn, and keep the restricted keyway doing what the owner paid for.
Medeco isn’t a sideline for us. We re-pin Maxum deadbolts, rebuild M3 and M3+ cylinders, and maintain document-controlled key records for restricted keyways. One call covers our Medeco sales & service work, car key replacement, and 24/7 emergency lockout response across Black Point-Green Point service area.

Common Medeco Locksmith Problems We Solve in Black Point-Green Point
- Seized canal-side and boat-access cylinders. Salt air off the Petaluma River and Novato Creek settles directly on gate and boathouse hardware. The hardened pins and sidebar inside a Medeco cylinder corrode until the key won’t fully insert, and by the time someone reports it, the guest or owner is already locked out of an outbuilding.
- Green-tinged keyways on seasonal second homes. Vacant vacation rentals sit unchecked for weeks at a time, letting fog moisture work into brass and steel. We regularly open Black Point-Green Point properties at season start and find the front-door Medeco turning like it’s full of sand.
- Worn pin chambers from repeated rental rekeys. Restricted-keyway cylinders on Airbnb and vacation-rental doors get re-pinned between every guest turnover. Done too many times with the wrong technique, the pin chambers wallow out and the cylinder loses its crisp feel.
- Stiff cylinders that aren’t actually broken. A stiff Medeco lock on an older waterfront home is almost always a corroded pin stack, not a failed lock body. We rebuild the stack with genuine Medeco pins and springs, restore the sidebar, and leave the original restricted keyway intact.
- Access coordination for off-site landlords. Most Black Point-Green Point lock and key work happens by phone or text with a property manager in another city. We coordinate rekeys on a schedule, handle the key handoff with the cleaning crew or maintenance person, and send the key-control documentation by email when we’re done.
Medeco Service in Black Point-Green Point: What Local Conditions Mean for Your Equipment
Here’s the thing about Medeco equipment in Black Point-Green Point that Medeco in Novato or a shop in Petaluma won’t fully appreciate: the cylinder that fails first is almost never the one the owner is standing in front of. The waterfront canal homes and boat-access doors along the Petaluma River and Novato Creek get direct salt spray, and because so many of those properties are second homes run by off-site managers, a seized gate cylinder can sit unnoticed for weeks until a guest or cleaner tries the restricted key and nothing turns. By the time we arrive, the pin stack has often swollen with corrosion and the sidebar is dragging against the keyway. What that means for a Medeco owner here is simple: expect the back gate, the boat-access door, and the detached garage to need service before the front door ever does. We quote a rebuild based on the cylinder condition, not the door it’s mounted on.
Medeco Models & Products We Service in Black Point-Green Point
We work across the Medeco line as an independent shop. That includes the Maxum residential deadbolt, the M3 and M3+ high-security cylinder, and the older Biaxial restricted-keyway cylinders still common on legacy waterfront homes. We also service Medeco deadbolts with restricted keyways, including key-card-controlled duplication systems. For high-security cylinders, we use genuine Medeco pins, springs, sidebars, and cam kits. Aftermarket internals undermine exactly what you paid Medeco for: a keyway that can’t be duplicated without your control. We keep common Medeco pin sizes and sidebar components stocked for Black Point-Green Point jobs, which means a typical re-pin or rebuild doesn’t wait on a parts order.
Medeco Service Pricing in Black Point-Green Point
Medeco work in Black Point-Green Point runs on honest ranges, not a bait price. A standard rekey on one Medeco cylinder lands between $65 and $120. A full cylinder rebuild with a seized pin stack and sidebar cleaning runs $110 to $170, depending on corrosion. Re-pinning a restricted-keyway cylinder to a manager key is $85 to $140 per cylinder. If you need multiple doors, outbuildings, and a boat-access door done in one visit, we quote a flat scope before work starts. Salt-corrosion rebuilds take longer than a clean indoor rekey, and our pricing reflects that honestly.
Call (833) 589-8078 and we’ll walk through your setup by phone. The price we quote is the price on the invoice. No dispatch fee discovered at the door.

FAQs – Medeco Locksmith in Black Point-Green Point
No. A restricted-keyway Medeco key can only be duplicated by presenting the key card and ID to the registered dealer who controls that keyway. That’s the entire point of the system. If a property manager can’t find the card, we can re-pin the cylinder to a new restricted keyway and issue fresh keys with a new card. Call (833) 589-8078 and we’ll walk through your key-control documentation by phone.
Direct salt exposure. Boat-access and canal-side cylinders face fog and salt spray that the front entry never sees. The hardened pins and sidebar inside the Medeco cylinder corrode until the key won’t turn, while the drier front lock keeps working. The fix is a cylinder rebuild, not a whole-lock replacement. Call (833) 589-8078 for a quote on the rebuild.
Yes. We build master-key and multi-level keying systems on Medeco restricted keyways. Each guest gets a key that operates only their unit, and the manager key opens everything. We keep the key-control ledger documented so you always know how many keys are in circulation. Call (833) 589-8078 and we’ll map out your cylinder schedule by phone.
Almost always a rebuild. A stiff Medeco cylinder is usually a corroded pin stack or a dragging sidebar, both of which we correct with genuine Medeco internals. We only recommend replacement when the cylinder body or sidebar is pitted beyond saving. Call (833) 589-8078 for a straight answer on your specific lock.
Yes, and that’s how most of our Black Point-Green Point work goes. We coordinate with the property manager, cleaner, or maintenance person, rekey or re-pin on the scheduled day, and send the key-control documentation and new key card by email. The owner never needs to be on-site. Call (833) 589-8078 to arrange it.
