A commercial door takes far more abuse than a residential one. A storefront entrance on Crenshaw Blvd or a restaurant door in Koreatown might cycle hundreds of times a day, and every one of those openings wears on the cylinder, the latch, the hinges and the closer. When something finally gives out, it usually happens at the worst time: a key that won't turn at opening, a door that won't latch at closing, or a deadbolt that jams halfway after a long weekend.

Crenshaw Lock Company has worked on Los Angeles doors since 1987, and owner and lead technician David Shar has seen most of what this city's commercial buildings can throw at a locksmith. That includes narrow-stile aluminum storefronts with Adams Rite-style deadlocks and hookbolts, older mortise locks in converted 1920s and 1940s buildings, and newer multifamily and mixed-use properties with commercial-grade lever sets and panic hardware.

We are mobile only, so there is no shop counter to drive to. Our technicians arrive with the parts and tools to diagnose the problem at the door itself. When a repair makes sense, we repair. When the hardware is worn past saving or was the wrong grade from the start, we explain the replacement options plainly so you can choose what fits your door, your traffic and your budget.

How it works in Los Angeles

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe what's happening: the type of door (aluminum storefront, hollow metal, wood), the hardware involved, and whether the building is currently secure. Photos of the lock face, the edge of the door and any markings on the cylinder help us bring the right parts.

  2. 2

    On-site inspection

    At your location we check how the door actually behaves: alignment in the frame, hinge or pivot wear, strike position, closer adjustment and the condition of the lock body. Many 'bad lock' calls turn out to be a sagging door or a misaligned strike, and fixing the cause keeps the new hardware from failing early.

  3. 3

    Clear options before work starts

    We explain what we found and lay out choices, such as replacing a cylinder versus the full deadlock, or rebuilding a mortise lock versus swapping it for a new commercial-grade unit. You hear the cost factors before we begin, not after.

  4. 4

    Repair or install

    We service or replace the hardware, matching backset, stile width and cutouts where possible so the door doesn't need new prep. For aluminum storefronts that means fitting the correct deadlock and cylinder length; for mortise doors it means matching the case size and function.

  5. 5

    Test, key and walk through

    We cycle the door repeatedly, confirm it latches and locks under closer tension, and test every key. If you're rekeying for staff turnover, we can set up keying so the right people have the right access, and we show you how the new hardware operates.

What affects the price

  • The type of door and frame, since narrow-stile aluminum storefronts, hollow metal doors and older wood doors each need different hardware and handling
  • Whether a repair is possible or the lock body, deadlock or exit device must be replaced outright
  • The grade and brand of the replacement hardware you choose, from standard commercial to heavy-duty Grade-1 units
  • How many doors and cylinders are involved, and whether you want them rekeyed alike or set up with different access levels
  • Whether the door needs adjustment or modification, such as realigning a sagging door, moving a strike or filling old cutouts
  • The time of the call, since after-hours and emergency visits differ from scheduled daytime work

Why Los Angeles chooses us

  • Serving Los Angeles since 1987, with owner David Shar personally leading the technical work
  • Fully mobile and available 24/7, so a door that fails after closing doesn't have to stay unsecured overnight
  • Experience with both modern aluminum storefront systems and the original mortise locks still found in older LA commercial and mixed-use buildings
  • We look for the cause of the failure, like door sag or closer problems, rather than just swapping parts
  • Straightforward explanations of repair versus replacement options before any work begins
  • Based in the 90008 area, with deep familiarity with the Crenshaw, Leimert Park and South LA commercial corridors

Commercial Door Hardware across Los Angeles

Our base is in the 90008 ZIP code, near Baldwin Hills Crenshaw Plaza and Leimert Park Village, so commercial doors along Crenshaw Blvd, Martin Luther King Jr Blvd and Slauson Ave are familiar ground. The storefronts here range from small shops in Leimert Park's village-planned blocks to retail spaces around the plaza, and many of them run on aluminum-frame doors that have been rekeyed, patched and reused through several tenants. Worn hookbolts, loose cylinders and closers that slam or fail to latch are common calls in this part of the city.

Further out, we work in West Adams (90018), where older buildings often still carry original mortise hardware that can sometimes be rebuilt rather than replaced, and around Exposition Park and USC, where offices and mixed-use buildings see heavy daily traffic. In Koreatown (90006) and Downtown (90012), dense restaurant and retail corridors put enormous wear on entry hardware, and in Hollywood (90046 and 90027), older commercial stock sits alongside newer buildings with panic bars and lever trim.

Because we're mobile, getting to you means navigating the same I-10, I-110 and I-405 traffic you do, so we don't promise arrival minutes. What we do offer is round-the-clock availability and a technician who understands the kinds of doors this city actually has, from 1920s mortise locks off Crenshaw to modern storefront systems near Union Station.

Commercial Door Hardware in Los Angeles — FAQs

Can you fix my aluminum storefront door lock, or does it need replacing?
Often it can be fixed. Many storefront problems come from a worn cylinder, a misaligned strike or a door that has sagged in its frame. We inspect the deadlock, cylinder and alignment first, then tell you whether repair or replacement makes more sense. Call (323) 997-8867 to describe the door.
Do you work on old mortise locks in older Los Angeles buildings?
Yes. Many buildings in West Adams, Leimert Park and other older neighborhoods still have original mortise locks. Some can be cleaned and rebuilt; others are better replaced with a modern commercial mortise lock that fits the existing pocket so the door doesn't need major modification.
Is there a shop I can bring the lock to?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your business, which is usually best anyway, since commercial door issues often involve the door and frame, not just the lock.
My business door won't lock at closing time. Can someone come tonight?
We are available 24/7 across Los Angeles. Call (323) 997-8867, tell us whether the building can be secured in the meantime, and we'll get a technician headed your way. We don't quote arrival times because LA traffic varies, but we'll keep you informed.
How much does commercial door hardware repair cost?
It depends on the door type, whether the hardware can be repaired or must be replaced, the grade of any new hardware, how many doors are involved and the time of the call. We explain those factors and your options before starting work.
Can you rekey all my business locks after an employee leaves?
Yes. We can rekey storefront cylinders, mortise locks and other commercial hardware so old keys no longer work, and we can set up keying so different staff have access only to the doors they need.
Do you install panic bars and door closers?
Yes. We repair, adjust and replace exit devices and door closers. A closer that's out of adjustment is a common reason doors fail to latch, so we often address it as part of a lock repair.
Which parts of Los Angeles do you serve?
We're based in 90008 and serve neighborhoods including Crenshaw, Leimert Park, Baldwin Hills, View Park-Windsor Hills, West Adams, Koreatown, Hollywood and Downtown, along with the wider Greater Los Angeles area and Ventura County.
