Medeco Lock Installation & Rekey in California: What to Know First
We provide independent Medeco lock installation & rekey in California, and most jobs are completed same day with a flat price quoted on the phone before our technician leaves the shop. A standard Medeco deadbolt rekey runs $180-$260; full installation of a new Medeco Maxum or M3 cylinder typically falls between $320-$480 depending on door prep and hardware condition. Gil Sanderson and our team have handled Medeco products across Los Angeles, the Bay Area, and Central Valley homes for over 42 years, and we back every job with our 90-Day Done Right Promise in writing. If you are staring at a Medeco key that won’t turn, a cylinder that feels gritty, or you need your home rekeyed after a move, call (833) 294-4584 and a live person will answer.
How Medeco Products Fail - and How We Fix Them
- Maxum 11* series deadbolts with sticky key rotation. The sidebar chambers in these Biaxial and original Maxum cylinders collect fine dust from California’s dry Santa Ana wind seasons, especially in inland areas like Riverside and San Bernardino counties. The key goes in fine but resists turning past 45 degrees. We disassemble the cylinder, clean each chamber with Medeco-compatible solvent, lubricate with Houdini Lock Lube (never graphite, which cakes in low humidity), and rekey to your new key code.
- M3 Multilock cylinders with premature sidebar spring fatigue. The M3’s angled sidebar springs work harder than Biaxial designs, and after 8-12 years of daily use they lose tension. The key turns but the bolt doesn’t throw fully. We replace with OEM Medeco sidebar spring sets, never generic substitutes, because aftermarket springs run 0.003″ undersized and fail again within 18 months.
- Medeco KeyMark residential cylinders with drilled plug faces. KeyMark uses a simpler pin stack than Biaxial/M3 and lacks the sidebar, so California locksmiths sometimes drill them improperly during lockouts, destroying the plug face. We source replacement KeyMark plugs with original Medeco keyways, fit them to the existing housing, and rekey rather than selling you a full new lock you don’t need.
- Medeco Logic electronic cylinders with intermittent “invalid key” errors. The Logic’s embedded chip and side-contact design corrodes in coastal California salt air, particularly in Orange County and Monterey Peninsula installations. We clean the contact array, test chip response with Medeco’s own programming equipment, and if the electronics are fried we can convert the lock to a mechanical Biaxial or M3 cylinder, saving the expensive housing.
- Original Medeco Biaxial rim cylinders with sheared tailpieces. These older cylinders, common in 1980s-1990s California apartment conversions, use a soft brass tailpiece that cracks where it meets the cam. The key works but nothing retracts. We machine a hardened steel replacement tailpiece to spec, reinstall the original cylinder, and rekey so your master key system stays intact.
Our Medeco Lock Installation & Rekey Process
- 1
Call and quote. You describe the lock, the symptom, and your California location. We quote a flat price before the truck rolls, and we put everything in writing - that part has never changed.
- 2
Tech arrives with ID. Our background-checked, uniformed technician presents identification at your door, inspects the Medeco hardware, and confirms the quote. No surprises.
- 3
Diagnose and decide parts. We determine whether OEM Medeco components, quality aftermarket equivalents, or a cylinder conversion makes sense for your specific model and budget. We explain the trade-off before touching tools.
- 4
Execute the installation or rekey. For rekeys, we pin to your new code, test all keys, and verify sidebar engagement on Biaxial/M3 designs. For installations, we machine door prep as needed, set proper backset and strike alignment, and cycle-test 50 times minimum.
- 5
Final inspection and documentation. We photograph the completed work, record your key code on our encrypted system (never on paper left behind), and hand you the written 90-Day Done Right Promise.
- 6
Cleanup and follow-up. We haul old hardware if you don’t want it, and our office calls within 48 hours to confirm satisfaction. If something isn’t right, we come back. No paperwork, no arguing.

Why California Homeowners Call Strongbox Lock & Safe Co. of California for Medeco Work
We are an independent Medeco service provider, not a factory-authorized dealer, which means we work for you and not a manufacturer’s sales quota. Our technicians carry Medeco, Schlage, Kwikset, Mul-T-Lock, and Abloy hardware on every truck, so if your Medeco cylinder is discontinued or your needs have changed, we can pivot to the right solution without a second appointment.
The 90-Day Done Right Promise covers every Medeco job we touch. If the key binds, the bolt sticks, or the finish flakes, we return and make it square. No receipt hunt, no claim forms. Gil Sanderson started this company on the principle that an honest quote and a clean job are the only two things a customer remembers, and we have operated that way for over 42 years. When you call (833) 294-4584, a live person answers, 24/7, including holidays.
FAQs
Medeco’s limited lifetime warranty on residential deadbolts covers defects in materials and workmanship, not damage from improper rekeying. Our technicians use factory pinning kits and follow Medeco chamber specifications, so your warranty remains intact for legitimate defect claims. If you are unsure whether your issue is a defect or wear, call (833) 294-4584 for a free second opinion on any written estimate.
Most residential Medeco rekeys are finished in 30-45 minutes on site. Biaxial and M3 cylinders require sidebar alignment verification that adds 10 minutes compared to standard pin-tumbler rekeys, but we do not charge extra for that time. Same-day appointments are available throughout California’s major metro areas. Call (833) 294-4584 to check today’s schedule.
No. Medeco uses proprietary keyways and sidebar mechanisms that are physically incompatible with Schlage SC1/SC4 or Kwikset KW1/KW10 keyways. We can, however, install a Medeco SFIC (Small Format Interchangeable Core) cylinder that operates on a master key system alongside your other brands, or we can rekey all your locks to Medeco for unified keying. We will explain both options and quote either path on the phone.
If your Medeco housing is solid and the bolt mechanism operates smoothly, rekeying or cylinder replacement is almost always the better value, typically 40-60% less than full replacement. We only recommend new hardware when the housing is cracked, the bolt is worn, or you want to upgrade from an older Biaxial to the current M3 security level. We tell you which category you are in before we start work.
We stock common Medeco cylinders, springs, sidebar kits, and key blanks for Biaxial, M3, and KeyMark lines on every California service truck. Discontinued Logic electronics or rare early-1980s keyways may require a two-day order from Medeco’s Ohio distribution center. We will tell you during the call which category your job falls into so you can plan accordingly. Call (833) 294-4584 with your lock model number for a straight answer.
