We service Medeco cylinders and deadbolts across Altadena, CA, including rekeys, repairs, and new installations. The work here is different from most cities because so many Altadena doors are pre-1950s solid wood with original mortise locks. That means a Medeco upgrade usually requires hand-fitting a high-security cylinder into a vintage door, not just drilling a fresh bore. We’re an independent shop, not Medeco-authorized, but we carry the OEM pins, tumblers, and tooling to do it right. Call (855) 791-2710 for a free estimate.
Why Altadena Residents Choose Us for Medeco Service
We’ve been pinning Medeco cylinders in the San Gabriel Valley for years. The brand’s tolerances are unforgiving: hard-milled brass, rotating pin tumblers, restricted keyways. That’s exactly why we like working on them. A Medeco Maxum or M3 isn’t a lock you want a generalist guessing at. We’ve seen what happens when someone drops in a generic pin kit; the key feels gummy, then stops turning altogether. Noel Tarkanian, our owner and lead technician, trained through the locksmithing and security technology program at Glendale Community College and spent years on residential and commercial work before starting Glendale Lock & Key. He’s the kind of technician who will tell you exactly why your cylinder is binding and whether it needs a re-pin or a full replacement. For Altadena homeowners, that matters. You’re not calling for a quick knob swap; you’re calling because your Medeco is acting up and you want it diagnosed, not guessed at. We also offer Medeco sales & service across the region, so we keep the parts on hand and know the product lines cold.

Common Medeco Locksmith Problems We Solve in Altadena
Here’s what we actually see on service calls in Altadena, from Janes Village up through the 1950s ranches off Lake Avenue:
- Stiff keys from dust in the keyway. Altadena’s dry summers put fine grit into everything. On older Medeco Original and Biaxial cylinders, that dust works into the rotating pin tumblers and gums them up. The key starts feeling stiff, then refuses to turn. We flush the cylinder, re-pin as needed, and the lock comes back smooth.
- Mis-cut duplicates without the key-control card. M3 and Maxum systems use restricted keyways. Homeowners lose the card, get a duplicate cut on an unregistered blank, and now the key works half the time or not at all. We can re-pin the cylinder and issue fresh keys, or start a new restricted keyway if the system needs to stay controlled.
- Deadbolt misalignment from seasonal door swell. Winter rains swell solid-wood doors. The side-load on the Medeco side-bar and tumbler stack causes sticking, and over time the bolt won’t seat. We realign and reinforce, rather than telling you to force the thumbturn.
- Vintage mortise locks with a Medeco cylinder torquing the faceplate. In Craftsman-era homes, a heavy door plus a high-security cylinder stresses the original mortise body. The deadbolt throws, but the door sags and the strike misses. This needs hand-fitting, not a new door.
- Wallowed bores on older installs. If a previous installer forced a cylinder into an undersized or worn bore, the whole assembly shifts under load. We ream the bore properly, install the correct adapter, and the cylinder sits square again.
Medeco Service in Altadena: What Local Conditions Mean for Your Equipment
Altadena’s Janes Village and the surrounding 1920s blocks still carry original factory mortise locks in solid-wood doors. That’s the one fact that shapes Medeco in La Cañada Flintridge and Altadena work here more than anything else. A homeowner who wants high-security hardware on one of these doors isn’t looking at a blank slab with a pre-drilled cross-bore. They’re looking at a door that was hand-fitted at the factory a hundred years ago, with a mortise pocket cut for hardware that hasn’t been sold in decades. Putting a Medeco Maxum deadbolt on that door means hand-mortising, fitting the cylinder into a vintage opening, and often leaving the original mortise entry intact as a working second lock. In a city with newer tract housing, the same job is a drill-and-install. Here, it’s restoration work that happens to include a high-security cylinder. Which is why we stock the adapters, strike plates, and OEM Medeco parts that make a vintage install hold up through the dry-summer-to-wet-winter cycle Altadena throws at its doors.
Medeco Models & Products We Service in Altadena
We work on the full Medeco lineup that shows up on Altadena doors: the original pin-tumbler deadbolt, the Biaxial cylinder and deadbolt, the M3 with its patented keyway, and the Maxum deadbolt with its hardened bolt and drill-resistant faceplate. Our repair-versus-replace stance is simple. If the cylinder body and tumbler stack are sound, we rekey or rebuild using genuine Medeco OEM pins and tumblers. If the bore is wallowed, the patented keyway is compromised, or the key-control card is gone and the system can’t be secured, we recommend replacement. For cosmetic parts like strike plates and escutcheons, we use quality aftermarket where it makes sense. Everything for a standard Altadena call is on the truck, so we don’t pad a two-visit job into a week.

FAQs – Medeco Locksmith in Altadena
Yes, in most cases. If you’ve lost the restricted keyway card, we can re-pin the cylinder to a new key set, provided the patented keyway itself hasn’t been compromised. If the keyway is damaged or someone cut duplicates on unregistered blanks, the secure path is a new restricted cylinder. Call (855) 791-2710 and we’ll tell you which situation you’re in.
It can, but it’s a hand-fitting job, not a drop-in. We mortise the cylinder into the solid rail, fit the strike to the existing jamb, and often leave the original mortise entry working alongside the Medeco. We’ve done this exact install in Janes Village, Medeco repair in East Pasadena, and on the surrounding 1920s blocks.
Dry-season dust works into the rotating pin tumblers on older Biaxial and Original cylinders, gumming them up. The key starts stiff, then binds. We flush and re-pin the cylinder, and it returns to normal. A fast diagnosis beats forcing the key and shearing a tumbler. Call us at (855) 791-2710 before it becomes a lockout.
Yes. We service and install Medeco service in San Marino and Altadena commercial hardware, including master-keyed cylinder builds and panic hardware that works with Medeco cores. For commercial work, we scope the job first and quote a written flat per-lock price before we start. Estimates are free.
If the cylinder body and tumbler stack are sound, repair and rekey is almost always the better value; a rebuilt Medeco generally outlasts a new mid-tier deadbolt. Replace when the bore is wallowed, the patented keyway is compromised, or a missing restricted card makes the system unsecurable. We’ll give you an honest read.
