We provide independent Medeco locksmith service across Cupertino, from rekeying a restricted-key M3 cylinder to fitting a high-security cylinder into a 1960s mortise lock that most shops won’t touch. What makes our Medeco work different here is the combination: genuine parts, sidebar-level repair, and an understanding of how Cupertino’s wet winters and Eichler-era doors affect high-security hardware. Call (877) 265-4385 for a free estimate, and we’ll tell you exactly what your Medeco lock needs before anyone is dispatched.
Why Cupertino Residents Choose Us for Medeco Service
Medeco is a different animal from a Schlage or Kwikset. The angled cuts on M3 keys, the sidebar, the restricted keyways. Those details matter when a lock binds or a key stops turning. Noel Carver, owner at Cypress Lock & Key, completed a locksmithing and security systems program at Fresno City College and has spent going on two decades running calls in this part of California. That training covered pin-tumbler service and high-security systems, which is why we work on Medeco in the field rather than telling you to ship the cylinder somewhere. Cupertino homeowners call us because we pin, clean, and service Medeco’s restricted-key systems on site while keeping existing hardware in place. We’re independent, not factory-affiliated, so we source genuine Medeco cylinders, sidebar springs, and restricted blanks without pushing you toward a single vendor’s stock. See our Medeco sales & service overview for the full picture of what we cover.

Common Medeco Locksmith Problems We Solve in Cupertino
- Restricted-key cylinders that stop turning smoothly. Cupertino’s dry summers put fine dust and grit into the air, and that grit finds its way into the sidebar channel of a Medeco M3 cylinder. The lock still works, but it feels scratchy, then it catches, then one day the key won’t turn at all. We clean the sidebar, re-lubricate with a dry film lube, and the cylinder runs like it should.
- Medeco Maxum deadbolts that bind after winter rains. This is a Cupertino seasonal pattern. Cool, wet winters swell wooden doors and frames, and a heavy Maxum deadbolt that was fine in September suddenly won’t throw fully in January. The cylinder isn’t the problem. The door is. We re-align the strike, adjust the frame where needed, and get the bolt throwing cleanly without replacing hardware you don’t need replaced.
- Worn or bent M3 keys. Medeco’s angled cuts are part of the security design, but they also mean a slightly bent key wears the sidebar unevenly. You’ll notice the key only works one direction, or you have to jiggle it. We cut fresh restricted keys from genuine Medeco blanks and check the sidebar for wear at the same time.
- Improperly rekeyed Medeco cylinders from a prior move-in service. Cupertino has a constant stream of executive rentals and international homeowners moving in and out. We regularly see Medeco cylinders where a previous service set pins for the wrong keyway or left out a sidebar spring. The lock “works” until it doesn’t. We strip, inspect, and re-pin correctly, then test with the new restricted key.
- Vintage mortise locks that need a high-security retrofit. Rancho Rinconada and Monta Vista are full of original 1960s mortise bodies. Homeowners want Medeco security but don’t want to replace the door or the vintage trim. We fit a Medeco high-security cylinder into that existing mortise body. Most shops decline this job. We do it regularly.
Medeco Service in Cupertino: What Local Conditions Mean for Your Equipment
Here’s what actually happens in Cupertino that doesn’t happen the same way two cities over. The housing stock here is split: 1950s-1970s single-family homes, many of them Eichlers or ranch-style with original mortise locks, and newer luxury developments with multi-point locking systems and gated entries. For Medeco owners, that split creates two very different service calls. In the older neighborhoods like Rancho Rinconada and Monta Vista, homeowners want a Medeco M3 cylinder dropped into a 1960s mortise body so they can keep the original door hardware and add restricted-key security. That’s a fit-and-pin job requiring vintage lock knowledge and current high-security tech skills. Most shops won’t attempt it because the cylinder tailpiece and mortise cam don’t line up without modification. We do it often enough that the process is routine. In the newer developments, the calls are different: multi-point lock bodies where a Medeco cylinder needs to integrate with a lift-lever mechanism, or gated-entry systems where the restricted-key plan has to extend across multiple doors. Cupertino’s status as a tech hub also means many of our Medeco clients are property managers and executives who need a documented key control trail. When you call us for Cupertino service area coverage, you’re getting a shop that understands both the 1962 mortise body and the 2024 smart-lock retrofit.
Medeco Models & Products We Service in Cupertino
We work on the Medeco Maxum deadbolt, the M3 (Maxum3) high-security cylinder, Maxum residential handlesets, and the older Original and Biaxial retrofit cylinders that still turn up in Cupertino’s 1960s homes. On parts, our position is simple: genuine Medeco cylinders, sidebar springs, and restricted key blanks only. Aftermarket copies of Medeco’s angled-cut key systems don’t hold tolerances, and they compromise the pick-resistance you paid for. We stock common Medeco components locally so Cupertino service calls don’t stall waiting on a part shipment. When a cylinder is just gummed up or mispinned, we clean, re-pin, and re-key it rather than push a replacement. We only recommend a new cylinder when the sidebar or body is genuinely worn past reliable service.
Medeco Service Pricing in Cupertino
Medeco work costs more than standard Schlage or Kwikset service because the parts cost more and the labor requires high-security training. Here’s what Cupertino homeowners can expect:
- Medeco rekey (existing cylinder): $85 to $145 per cylinder, including genuine pins and two restricted keys.
- Medeco M3 cylinder replacement: $120 to $220 per cylinder, depending on mortise or cylindrical fitment.
- Medeco Maxum deadbolt install (new): $190 to $320 including hardware.
- Sidebar cleaning and lubrication service: $65 to $95 per cylinder.
- Vintage mortise retrofit with Medeco cylinder: $180 to $280, including modification and testing.
What drives the price is the cylinder type, whether we’re fitting into existing hardware or modifying a mortise body, and how many restricted keys you need. Every estimate is free, and the full price is quoted on the phone before anyone is dispatched. That’s the price on the invoice. No dispatch fee added at the door. Call (877) 265-4385 for an exact quote on your Medeco lock.

FAQs – Medeco Locksmith in Cupertino
No. We’re an independent Medeco service provider, not manufacturer-affiliated or authorized. That independence means we can source genuine Medeco cylinders, sidebar springs, and restricted key blanks without steering you toward a single vendor’s stock or factory service channel. For most Cupertino homeowners, and those needing Medeco service in Saratoga, that means faster service and honest repair-vs-replace advice.
Genuine Medeco parts only. Aftermarket copies of Medeco’s angled-cut key systems don’t hold tolerances, and they compromise the pick-resistance of the lock. We use genuine Medeco cylinders, sidebar springs, and restricted key blanks on every job. If a part isn’t available genuine, we’ll tell you and wait for it rather than substitute.
Most rekey and cylinder-service jobs are done same-day, often within an hour of arrival. A standard Medeco rekey takes 30 to 45 minutes. A vintage mortise retrofit takes longer, usually two to three hours, because of the modification work involved. We’ll give you a realistic time estimate when you call, based on the specific lock and door.
We service the Medeco Maxum deadbolt, the M3 (Maxum3) high-security cylinder, Maxum residential handlesets, and the older Original and Biaxial retrofit cylinders. If you have a Medeco lock that isn’t on that list, call (877) 265-4385 and describe it. We’ll tell you honestly whether we can service it.
That depends on whether we’re rekeying an existing cylinder ($85 to $145), replacing a cylinder ($120 to $220), or fitting a Medeco into a vintage mortise body ($180 to $280). The estimate we give on the phone is the full price, and it’s the price on the invoice. No arrival surcharge. Call (877) 265-4385 and we’ll quote your specific lock.
