Citadel Locksmith provides independent Medeco service across Menlo Park, from cylinder rebuilds on century-old mortise doors to fresh M3 installations on new construction.

Why Menlo Park Residents Choose Us for Medeco Service

We work on Medeco hardware the way a mechanic works on one make of engine for twenty years, including Woodside Medeco service. Roland Vásquez, our owner, has been pinning and retrofitting Medeco cylinders since the Biaxial era, long before M3 keyways showed up on every high-end remodel in Menlo Park. That matters because Medeco isn’t a brand you figure out on-site with a YouTube video and a prayer.

Our techs have rebuilt Maxum deadbolts that seized after three foggy winters in the Willows, re-pinned legacy mortise cylinders whose cams had worn past spec, and re-coded restricted keyways after a lost key wiped out key control. We’re not authorized or endorsed by Medeco, and we’re honest about that; our advice comes from field repairs, not a dealer agreement. For Menlo Park homeowners, that means a straight answer about whether your existing hardware is worth saving.

Common Medeco Locksmith Problems We Solve in Menlo Park

  • Fog-season corrosion on exterior cylinders. Menlo Park’s damp winter air sits on north-facing doors for months, pitting the hardened-steel pins and sidebars inside Maxum and M3 cylinders. A deadbolt that turns stiffly or jams halfway is usually not a lubrication issue; it needs a pin-stack rebuild.
  • Swollen jambs and worn strikes on older bungalow doors. The Willows and Allied Arts are full of 1920s and 1940s wood-frame homes where wet winters swell the jamb and dry summers shrink it back. A Medeco bolt that seated cleanly in October stops catching the strike by February. We true the strike and adjust alignment rather than tell you to slam the door harder.
  • Legacy Medeco cylinder bodies worn past spec. Single-cylinder deadbolts installed decades ago on the original mortise doors develop play in the cam and pin wear, so the key turns loosely without throwing the bolt cleanly. Sometimes a re-pin fixes it; sometimes the body is done and needs replacement. We’ll tell you which.
  • Key control erosion on restricted keyways. When the only restricted key gets lost or handed to a contractor without a card, that cylinder’s key control is effectively gone. We re-pin or re-code it so only the keys we issue to you will turn the plug.
  • Mismatched hardware after a renovation. Menlo Park remodels routinely keep the old Medeco front lock while a new pre-drilled back door gets a builder-grade Kwikset. One key should open the whole house, and that means keying everything to a single Medeco master, not just rekeying one lock.

Medeco Service in Menlo Park: What Local Conditions Mean for Your Equipment

The Willows and Allied Arts neighborhoods create a specific Medeco service pattern that doesn’t exist in most neighboring cities, though we also provide Redwood City Medeco service. These 1920s and 1940s bungalows are routinely renovated with new doors while the original mortise front entry stays put. The result is a Medeco cylinder on the front door and a builder-grade Kwikset on the back door of the same house. We see this exact pairing several times a month, and it changes the job entirely: the real work is building a single keyed master across mismatched hardware, not rekeying one lock. On a recent house in the Willows, the original mortise front door carried a worn single-cylinder Medeco deadbolt whose bolt no longer seated in the strike, while the back door had a newer Kwikset on a replacement door. We re-pinned the Medeco cylinder with fresh pins and cam, trued the worn strike and adjusted the swollen jamb, then keyed the Kwikset back door and side gate cylinder alike to a single restricted Medeco master so one key worked the whole house. That’s the Menlo Park Medeco job in one paragraph.

A lock is only as strong as the decision behind it. If you’re going to run Medeco on the front door, the back door and side gate need to match, or you’ve bought a very expensive front door lock and left the rest of the house open.

Medeco Models & Products We Service in Menlo Park

We service the full Medeco line that shows up in Menlo Park homes, plus Medeco service in Ladera: the Maxum deadbolt, Biaxial cylinders, the M3 and M3+ high-security cylinders, and the original hard-to-duplicate keyway cylinders still running on legacy mortise bodies. Our parts approach is straightforward: we fit genuine Medeco cylinders, pins, and cams whenever the existing hardware supports them. We don’t press aftermarket knockoff pins into a restricted keyway, and we don’t upsell a new lock when a clean re-pin and strike adjustment fixes the problem. If a worn legacy body needs to be rebuilt or replaced, we’ll show you the wear and explain the cost difference before touching anything.

Medeco Service Pricing in Menlo Park

Medeco work in Menlo Park typically runs between $150 and $400 depending on the cylinder type, the number of locks on the property, and whether we’re re-pinning, re-coding, or replacing hardware. A simple single-cylinder rekey sits at the lower end; a full master-key system across multiple doors and a gate lands higher. What drives the cost: Medeco pins and cams cost more than generic parts, restricted keyways take longer to re-code than standard cylinders, and master-keying across mismatched hardware is inherently more labor than a one-lock swap. Every estimate includes a phone quote with a firm number before we dispatch. No call-out surcharge added on arrival, and the price we quote is the price on the invoice.
