Medeco Locksmith in Los Angeles, NY | Novak Lock & Security
We’re an independent Medeco locksmith serving Los Angeles, and the short answer is this: we cut, program, and service Medeco high-security locks daily across the city’s seismic-shifted door frames, coastal corridors, and ADU-heavy neighborhoods. What makes our Medeco work different here is that we stock genuine Medeco cylinders, pins, springs, and key blanks on our Los Angeles service vans, so a rekey or repair that would take other shops two trips and a week of waiting usually gets done on the first visit. We are not a factory-authorized Medeco dealer, and we don’t pretend to be. We’re an independent service provider that has worked on Medeco M3, Biaxial, KeyMark, and Duracam hardware across Los Angeles for years. Call (331) 310-8471 for a free estimate, quoted in writing before anyone is dispatched.
Why Los Angeles Residents Choose Us for Medeco Service
Medeco locks are not Kwikset. The sidebars, the angled cuts, the restricted keyways, the pin tolerances - this is precision hardware, and a locksmith who only sees Medeco once a month will misdiagnose it. We see Medeco weekly across Los Angeles, from early-1900s Craftsman bungalows in Highland Park still running obsolete mortise cylinders to post-1980 hillside estates in Bel Air running M3 deadbolts. Daniel Novak, our owner, learned the trade at Queensborough Community College and apprenticed under a retired locksmith who serviced commercial accounts in Midtown. He has spent two decades working doors, deadbolts, and cylinders, and he built Novak Lock & Security on exactly the kind of high-security retrofit work Los Angeles homeowners and property managers call us for. If a Medeco sidebar binds or a cylinder seizes, we name the part, state what we found, and tell you what it costs before we touch anything. That’s the whole business. The name on the van is the same name on the invoice.
Common Medeco Locksmith Problems We Solve in Los Angeles

- Seismic frame racking binds Medeco sidebars. Los Angeles sits on an active fault network, and after tremors - or after the kind of slow settling that follows a big event like Northridge - wood-framed door openings shift. A Medeco M3 or Biaxial deadbolt with high-tolerance sidebars will fail to throw even when the bolt looks clear. We re-pin and realign the strike, and the lock works again.
- Salt-air corrosion seizes cylinders in Venice, Santa Monica, and San Pedro. Marine-layer humidity accelerates corrosion on exterior lock hardware in a way locksmiths 15 miles inland never see. Medeco cylinder plugs and springs seize within a year or two of coastal installation. We disassemble, clean, lubricate with the right product, and replace springs if they’ve lost tension.
- Winter rain-swollen door frames in Laurel Canyon and Nichols Canyon. The same Medeco deadbolt adjusted perfectly in dry October will refuse to throw by January. Hillside home frames swell with rare winter rains, and the deadbolt misaligns against the strike. This is seasonal, recurring work on the same addresses year after year.
- Lost or broken Medeco keys. Medeco’s restricted keyway means a hardware store can’t duplicate your key. Without the original key and card, we disassemble and rekey the cylinder from scratch. We re-cut from your key card when you have it, and we re-pin when you don’t.
- Legacy Medeco Biaxial and Duracam hardware at end of life. Older Medeco systems still work, but repair parts for some Biaxial and Duracam lines are discontinued. When a corroded or damaged cylinder should be replaced rather than laboriously rekeyed, we say so and recommend upgrading to M3.
Medeco Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Medeco page. Los Angeles saw an ADU permitting boom after the 2017 and 2020 ordinance overhauls positioned the city as the national leader in accessory-dwelling-unit construction. Tens of thousands of garage conversions and backyard cottages went up, and many owners paired Medeco cylinders with local-only master key systems to manage tenant turnover across multiple units. That created a concentration of Medeco rekeys and master-key service in Los Angeles that neighboring cities simply don’t have at the same scale. A locksmith in Burbank might service one Medeco master system a month. We service them weekly. The demand pattern is different here, and so is the failure pattern: seismic racking, salt-air seizing, and seasonal swelling all hit Medeco hardware harder in Los Angeles than they do ten miles inland. We carry the key blanks, pins, and specialty tools to handle that volume, and our techs have seen enough Los Angeles Medeco installations to know what fails first and why.
Medeco Models & Products We Service in Los Angeles

We service the full Medeco line that shows up on Los Angeles doors: Medeco M3 (including M3B and M3-AK), Medeco Biaxial (legacy systems still common in older commercial and multifamily buildings), Medeco KeyMark (XC cylinders), and Medeco Duracam (legacy cam locks and door cylinders). We stock genuine Medeco cylinders, pins, springs, and key blanks unless a customer explicitly requests a cheaper retrofit. For older Biaxial or Duracam hardware where repair parts are discontinued, we recommend upgrading to M3 rather than sinking money into a cylinder that’s past its service life. That’s the honest call, and we make it in writing before any work starts. For more on our Medeco sales & service capabilities, see our Medeco sales & service overview.
Medeco Service Pricing in Los Angeles
Here’s what Medeco service costs on a Los Angeles job, in writing, before we dispatch. A standard Medeco cylinder rekey typically runs $45-$75 per cylinder. Installing a new Medeco M3 deadbolt runs $180-$340 depending on finish and cylinder options. Rekeying an existing Medeco master key system to a new key profile runs $85-$150 per cylinder, and complex master-key reconfigurations are quoted per job after we see the system. A lost or broken Medeco key that requires disassembling and rekeying from scratch typically runs $60-$110 per cylinder. What drives the cost: the number of cylinders, whether we’re re-pinning or replacing hardware, and whether it’s a coastal corrosion job that needs full disassembly. Every estimate is free, and Haven Standard Clause 1 says the price on the phone is the price on the invoice - no call-out surcharge added on arrival, no bait-and-switch. Call (331) 310-8471 for an exact quote on your Medeco hardware.

FAQs - Medeco Locksmith in Los Angeles
Seismic frame racking shifted the door frame just enough to misalign the cylinder and bind the high-tolerance M3 sidebar, even when the bolt looks clear. We re-pin the cylinder on-site and realign the strike plate so the deadbolt throws cleanly. Most Los Angeles post-tremor Medeco failures we see are frame alignment issues, not lock failures. Call (331) 310-8471 and we’ll diagnose it same day.
Not at a hardware store. Medeco’s restricted keyway requires the original key and key card, and most Los Angeles hardware counters don’t stock Medeco blanks or have the cutting equipment. We do, and we’re one of the few independent shops in Los Angeles that cuts Medeco keys on-site. If you’ve lost all keys and don’t have the card, we disassemble and rekey the cylinder from scratch.
Marine-layer humidity accelerates corrosion on exterior Medeco cylinders in Venice, Santa Monica, and San Pedro, and we regularly see plugs and springs seize within a year or two of coastal installation. The fix is full disassembly, cleaning, and replacement of corroded springs. If the core is too far gone, we recommend replacing with a new cylinder rather than trying to rekey a seized one. Coastal Medeco owners should plan for annual maintenance - call (331) 310-8471 and we’ll schedule it.
It depends on the condition and which parts have failed. Some Biaxial repair parts are still available, but if the cylinder is corroded or the sidebar mechanism is worn, we typically recommend upgrading to M3. Biaxial is legacy hardware, and putting money into a cylinder at end of life is a poor investment. We’ll inspect it in person and give you a written recommendation with both options priced.
Yes. Given Los Angeles’ ADU surge, we set up Medeco master key systems for owners managing garage conversions, backyard cottages, and multi-unit rentals all over the city. We design the key hierarchy, pin the cylinders, and cut the keys from your key card. You get a written scope and flat per-lock pricing before we start. Call (331) 310-8471 for a free estimate on your ADU system.
