Why Palo Alto Residents Choose Us for Medeco Service
We’ve been fitting and servicing Medeco cylinders in Palo Alto for over 42 years. Gil Sanderson, our owner, learned this trade at Los Angeles Trade-Technical College and has spent the better part of three decades doing locksmith work up and down California. He started by sorting key blanks in his father’s hardware shop. That background shows in how we approach Medeco work here: we understand the mechanical puzzle of a lock, not just how to swap it out.
Palo Alto’s housing demands both ends of the skill spectrum from a Residential Locksmith in Palo Alto. A 1906 Craftsman on Waverley Street needs a different touch than a gut-renovated property with HomeKit-integrated smart locks. We stock OEM Medeco parts for both. Our technicians are background-checked, uniformed, and present ID at every door. We quote a flat price on the phone before the truck rolls. Every job carries our 90-Day Done Right Promise in writing.
We’re not factory-authorized by Medeco. What we are is experienced - over 20 years of field work pinning, rekeying, and repairing Medeco biaxial and M3 cylinders, including restricted keyways and factory code keying for Palo Alto homeowners and Stanford-area property managers.
Common Medeco Locksmith Problems We Solve in Palo Alto
- Corroded sidebar springs in Biaxial cylinders. Palo Alto’s marine fog and morning dew settle into exterior deadbolts on older iron and steel hardware, corroding the sidebar springs that give Biaxial its pick resistance. The key turns halfway, then binds. We disassemble the cylinder, replace springs with OEM parts, and lubricate with climate-appropriate protectant.
- Worn brass pin stacks in M3 cylinders after repeated rekeying. Stanford’s academic calendar drives intense rental turnover - 17,000+ students, postdocs, and visiting scholars cycling through leases each term. Some Medeco M3 units get rekeyed three or four times in two years. The brass pins wear oversize, causing key duplication failures and shimming vulnerabilities. We measure pin wear with a micrometer and replace the full stack when tolerances exceed factory spec.
- Broken retaining clips on Biaxial key-in-knob cylinders. Original Craftsman mortise locks in Professorville and the 94301 historic district often have set screws that homeowners overtighten during DIY adjustments. The retaining clip fractures, letting the cylinder slip. We stock OEM clips, but we’ll also show you the proper torque so it doesn’t happen again.
- Frozen actuator cams on M3 deadbolts in coastal moisture zones. Properties in 94301 and 94303 without regular lubrication develop corrosion between the cam and housing. The key works, but the bolt won’t throw. We disassemble, ultrasonically clean the components, and reassemble with OEM lubricant rated for marine-exposure environments.
- Keyway incompatibility between Biaxial and M3 systems. Palo Alto homeowners upgrading one door at a time often end up with mixed generations. We can key M3 cylinders to match existing Biaxial master key systems where the keyway geometry allows, saving the cost of full-system replacement.
Medeco Service in Palo Alto: What Local Conditions Mean for Your Equipment
Palo Alto’s 94301 corridor includes Professorville, a National Register Historic District where municipal guidelines often require period-compatible lock upgrades. Medeco cylinders must be retrofitted into original mortise cases without visible alteration. That’s a niche skill. Most locksmiths in Mountain View or Sunnyvale won’t touch it - they don’t carry the adapter sleeves, don’t know the escutcheon clearances, and haven’t spent afternoons filing a cylinder tailpiece to fit a 1910 mortise mechanism.
We rekeyed an entire 1906 Craftsman on Waverley Street in Professorville after a new owner moved in. The front door had original Baldwin mortise locks with two Medeco Biaxial cylinders that had corroded sidebars from decades of fog exposure. Our tech disassembled the cylinders, replaced the sidebar springs with OEM parts, repinned the cylinders to the new key code, and reinstalled them flush with the original escutcheon - preserving the historic look while restoring high-security function.
This combination of genuinely antique mortise-lock work and top-tier security hardware on the same block is unusual. Newer-built neighboring cities don’t present this particular puzzle. We do. Medeco sales & service is one of our core competencies, and we’ve adapted it specifically for Palo Alto service area conditions.
Medeco Models & Products We Service in Palo Alto
We work on the full Medeco residential and light Commercial Locksmith - Palo Alto line:
- Medeco Biaxial - The original high-security cylinder with angled cuts and sidebar. Still common in Palo Alto homes installed 1990-2010. We stock OEM sidebar springs, pins, and key blanks for same-day repair.
- Medeco M3 - Current flagship with pickup-resistant slider sidebar and tighter tolerances. Our preferred recommendation for new installations and replacements when a Biaxial cylinder is beyond cost-effective repair.
- Medeco 32S - Key-in-knob and deadbolt cylinder format. Frequently found in retrofit applications on historic Palo Alto homes where a full mortise replacement would violate district guidelines.
We use only OEM Medeco pins, springs, and sidebars for repairs to preserve the security rating. For non-critical components like retaining clips, we offer quality aftermarket equivalents for cost-conscious clients. When repair exceeds 60% of replacement cost, we advise stepping up to a current M3 cylinder. We stock common M3 keyways and can often rekey to your existing master system.

FAQs - Medeco Locksmith in Palo Alto
Sometimes. The M3 and Biaxial use different keyway profiles, but certain M3 keyways are backward-compatible with Biaxial blanks. We need to examine your existing key and the M3 cylinder face to confirm. If the keyways don’t match, we can key both to a new master system. Call (833) 294-4584 - bring the key to our shop or schedule a tech visit for same-day assessment.
Probably. Palo Alto’s marine-influenced climate corrodes lock internals faster than inland Valley cities. Sticking usually means corroded sidebar springs or gummed pin chambers from dew exposure. Don’t force the key - that shears pins. We disassemble, clean ultrasonically, replace corroded springs with OEM parts, and apply protectant rated for coastal conditions. The 90-Day Done Right Promise covers our work.
Yes. The Medeco 32S and certain rim cylinder formats adapt to period mortise cases with proper tailpiece modification. We’ve done this work in Professorville and the 94301 historic district where visible alteration is restricted. We measure your case, machine or file the tailpiece to fit, and preserve the original escutcheon. This is not a stock-item installation - it requires field fitting.
Medeco mechanical deadbolts don’t have electronic components, so they don’t “integrate” directly. What we do is pair a Medeco cylinder with a compatible smart lock housing - Schlage Encode, Yale Assure, or August - that supports HomeKit, Google Home, or Alexa. You get keyless entry plus the physical security of a Medeco restricted keyway. We install and configure both in Palo Alto.
Every 18 to 24 months for exterior doors exposed to fog and dew. The marine layer here corrodes steel springs and brass pins faster than drier inland climates. A quick lubrication and pin-chamber inspection prevents the intermittent binding that leads to forced keys and broken cylinders. Our $89 Seasonal Tune-Up covers this. Call (833) 294-4584 to schedule - we often have same-day availability in Palo Alto.
