Cypress Lock & Key provides our Medeco services across Los Altos, CA (ZIP codes 94022, 94023, and 94024). We cut, pin, and repair Medeco cylinders, and what makes our Medeco work here different is that we regularly consolidate five or six separate key schedules on Los Altos properties that have detached garages, pool houses, and guest units into one clean Medeco master key system. We’re not a dealership or an authorized factory affiliate; we’re a local shop that works on the locks you already have. For a Medeco cylinder that’s binding, stiff, or mis-keyed after a remodel, call (877) 265-4385 and we’ll give you a straight read on the problem.
Why Los Altos Residents Choose Us for Medeco Service
Medeco is a specific animal. The restricted keyways, the sidebar pins, the rotation of the pins as the key enters – it all works differently than standard Schlage or Kwikset. If you’ve ever handed a Medeco key to a shop and watched them squint at it, you know what we mean. Our techs cut and pin Medeco cylinders regularly. That includes the Maxum deadbolt, the M3 high-security cylinder, the Maxum 11 Series deadbolt, and the original pin-tumbler restricted-keyway cylinders you still find on 1960s and 70s homes around Los Altos. Noel Carver runs Cypress Lock & Key, and he’s been turning Medeco cylinders long enough to know which wear patterns are worth repairing and which belong in the scrap bin. For Los Altos homeowners with original restricted-keyway hardware, that knowledge saves money and preserves the master schedule. We also handle Medeco repair in Stanford for nearby properties.
We stock the correct Medeco keyway blanks and pin kits locally, which means we don’t special-order a blank behind a big-box counter and call you back a week later. That matters when a deadbolt won’t throw on a rainy Los Altos night. We also understand how Medeco hardware behaves in Los Altos service area conditions – the dry summers, the winter damp that swells door slabs, and the mid-century ranch doors that shift with the seasons. When you call, whoever answers understands the lock. Not just the phone number.

Common Medeco Locksmith Problems We Solve in Los Altos
- Seasonal deadbolt binding on mid-century ranch doors. Every Los Altos winter, the damp air swells 1950s and 60s wood door slabs just enough to shift the strike plate out of alignment. A Maxum deadbolt that worked flawlessly in September suddenly needs the bolt thrown hard or refuses to seat at all. That’s usually a re-fit and strike adjustment, not a lock failure. We fix it the same day.
- Stiff or intermittently binding key insertion on original Medeco cylinders. Los Altos homes built in the 1960s and 70s often still have original Medeco restricted-keyway cylinders. Over the years, keys have been cut by multiple shops or copied by homeowners without the correct blanks. That degrades the sidebar and rotation pins until the key only goes in halfway or binds on the way out. We re-pin the cylinder and issue correctly cut restricted blanks.
- Dry, corroded M3 and Maxum cylinders on pool houses and detached garages. Los Altos properties with detached structures often have Medeco locks that go years without service. The hardened bolt and cam bind, the cylinder dries out, and homeowners mistake normal wear for a broken lock. We clean, lubricate, and re-fit before recommending replacement.
- Broken master-key schedules after a remodel. After a Los Altos remodel, original Medeco high-security cylinders often end up mixed with new builder-grade knob locks and smart locks on the same property. The master schedule no longer holds, keys cross between schedules, and suddenly nobody’s sure which key opens what. We inventory every door, pull the mix of cylinders, and re-pin the property to one clean Medeco master schedule.
- Lost restricted keys with no way to copy them locally. Medeco restricted keyways mean you can’t walk into a hardware store and get a copy. Many Los Altos homeowners don’t realize that until they lose the last key to the home office door. We handle restricted key duplication and, when needed, rekey the cylinder so the lost key dies.
Medeco Service in Los Altos: What Local Conditions Mean for Your Equipment
Here’s the thing about Medeco work in Los Altos that you won’t find on a generic service page. This town has almost no commercial core, so locksmith work here is dominated by residential rekeying, master-key systems, and work on large single-family lots – not storefront lockouts. And those lots, especially in Los Altos Hills and the larger in-town parcels, often have detached garages, pool houses, and guest units on separate keys or older master-key systems. A single property can require five or six distinct key schedules, and after a remodel, homeowners frequently want everything brought under one Medeco master key. That’s not a typical job in most cities. In Los Altos, it’s the job, and we offer similar Medeco in Loyola for properties in that area. The seasonal door swelling we mentioned doesn’t help either. When a damp February swells a ranch door slab on a Los Altos Hills property, the deadbolt that’s misaligned by two millimeters can feel fully broken. For a homeowner with four structures and one deadbolt on each, that’s four headaches at once. We handle the re-fit and, if the schedule is already messy, consolidate everything into one restricted master system while we’re there. Know your hardware, know your options – the rest is just turning a key.
Medeco Models & Products We Service in Los Altos
We service the full Medeco high-security core lineup that appears in Los Altos homes: the Medeco Maxum deadbolt, the Medeco Maxum 11 Series deadbolt, the Medeco M3 high-security cylinder, and the original pin-tumbler restricted-keyway cylinders still installed on many 1960s and 70s ranch homes. We use genuine Medeco replacement cylinders, pins, and restricted-keyway blanks when a lock is serviceable. We only turn to quality aftermarket hardware when it’s a hidden interior application or a budget-driven repair. Our honest stance on repair-versus-replace: a Medeco cylinder is almost always worth repairing and re-keying rather than replacing. But a corroded or mis-keyed one gets replaced outright so the master schedule stays clean. That keeps Los Altos turnaround fast – the cylinders and blanks are already on the truck.
Medeco Service Pricing in Los Altos
Medeco service in Los Altos depends on what’s actually wrong. A strike re-fit or seasonal adjustment is less involved than a full cylinder replacement with new restricted blanks. Rekeying a single Medeco cylinder falls somewhere in the middle, and a whole-property master-key consolidation (say, four or five cylinders across a house, garage, and pool house) is a bigger job that we scope out thoroughly before we start. What you’ll always get from us: the full price quoted on the phone before anyone is dispatched, and that price is the price on the invoice. No arrival markup, no bait pricing. That’s a problem in this trade and we answer it head-on. Call (877) 265-4385 for an exact quote – estimates are free.

FAQs – Medeco Locksmith in Los Altos
We rekey restricted Medeco cylinders as an independent service provider. We hold the correct keyway blanks and pin kits, and we don’t require you to go through a Medeco-authorized dealer or wait on factory service. If you have restricted keys that have been copied over the years and the cylinder is binding or the key is sticky, we can re-pin it and cut fresh restricted blanks on site. Call (877) 265-4385 to confirm your keyway and get a quote.
Usually yes. We’ve done exactly this on Los Altos Hills properties where a remodel left detached garage, pool house, and main entry on three different restricted keyways, plus a couple of builder-grade knobs mixed in. Our tech inventoried every door, replaced a worn cam in one garage M3 cylinder, and pinned the entire property to a single Medeco master schedule with restricted blanks. If you have separate key schedules on your Los Altos Hills property, call (877) 265-4385 and we’ll map what you have before quoting the consolidation.
The damp Los Altos winter air swells the stiles and rails on mid-century ranch door slabs, shifting the strike plate just enough to make the bolt throw hard or refuse to seat. It’s not your Medeco lock failing – it’s the door moving around it. We adjust and re-fit the strike, and sometimes deepen the bolt pocket, and the deadbolt goes back to smooth. Call (877) 265-4385 if your Medeco is sticking – same-day adjustments keep the fix simple.
That’s almost always accumulated wear in the rotation pins and sidebar, often made worse by keys that were cut at a shop without the correct restricted blanks, or homeowner copies made from a worn original. The key enters the keyway but the cut depths don’t match what the sidebar expects, and the cylinder binds partway in. We re-pin the cylinder and cut correct restricted blanks so the key slides clean. If you’re fighting your Medeco key in Los Altos, call (877) 265-4385 – this is a fast fix we do on site.
We can, with a clear understanding of what the Medeco gives you and what the smart lock gives you. A Medeco high-security cylinder earns its keep on the primary entry, the detached garage, the guest unit – the doors where key control matters. Adding a smart lock or keypad to a secondary entry is fine, but we keep the restricted master schedule clean so you don’t end up with keys crossing between the mechanical and electronic doors. That’s a conversation we have regularly in Los Altos. Call (877) 265-4385 to talk it through.
