A commercial door is used far more than a home door. A shop on Myrtle Avenue may open and close its front door hundreds of times a week, and a restaurant door gets pushed, pulled, kicked open with a cart and slammed at closing. Over time that wears down latches, closers, panic devices, pivots and strikes. A door that drags, a lock that sticks, or a handle that wobbles is usually giving you early notice before it fails completely, often at the worst moment, like closing time or in the middle of a lunch rush.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar's team handles commercial hardware as a core part of the work. We repair and replace hardware on storefront doors, aluminum-frame doors, and older mortise-lock doors. We are mobile only, so there is no storefront to visit. We come to your building with the tools and parts needed to assess the door on site.

Monrovia has an unusual mix of buildings. Old Town has small storefronts of different ages, some with original wood-and-glass doors and others with aluminum-frame replacements added over the decades. That mix means no two doors are quite alike, and the right fix depends on what is actually hanging in the opening. We look at the door, the frame, the closer and the way the building is used before recommending a repair or a replacement.

How it works in Monrovia

  1. 1

    Call and describe the door

    Call (323) 997-8867 any hour. Tell us what type of door it is (aluminum storefront, wood, or older mortise), what it is doing, and whether the business can be secured in the meantime. That helps us bring the right parts.

  2. 2

    Inspect the whole opening

    We examine the lock, latch, strike, hinges or pivots, closer and frame. Many hardware complaints are really alignment or closer problems, so we check the door's swing and fit before blaming the lock.

  3. 3

    Explain repair versus replace

    If worn parts can be rebuilt or adjusted, we say so. If the hardware is failing, mismatched or no longer supported, we explain why replacement makes more sense and what your options are before work begins.

  4. 4

    Repair or install the hardware

    We service or swap storefront locks, mortise cylinders and cases, exit devices, handles, pulls, and closers. On aluminum-frame doors we work within narrow stiles and the existing preps where possible.

  5. 5

    Rekey or key as needed

    If hardware is replaced, or keys have been lost or passed around among former staff, we can rekey so the business starts with a clean set of keys, and organize keying for multiple doors if needed.

  6. 6

    Test and secure before we leave

    We cycle the door repeatedly, check that it latches without slamming or dragging, test the keys, and make sure the door locks securely before we leave.

What affects the price

  • The type of door and frame: aluminum storefront, wood, or mortise doors each use different hardware and labor.
  • Whether the existing hardware can be repaired or needs full replacement, and how available the parts are for older or discontinued models.
  • The grade and type of hardware chosen, such as standard locksets, heavy-duty mortise cases, or panic and exit devices.
  • How many doors are involved and whether keying needs to be coordinated across them.
  • The time of the call, since after-hours and emergency visits are handled differently from scheduled daytime work.
  • Related fixes the door needs, such as closer adjustment, strike alignment, or frame repair that affects how the hardware works.

Why Monrovia chooses us

  • Fully mobile service: we come to your Monrovia business instead of asking you to bring anything to a shop.
  • Serving the region since 1987, with long experience across older mortise hardware and modern aluminum storefronts alike.
  • Available 24/7, so a door that will not lock at night can be dealt with instead of leaving the building exposed.
  • We diagnose the whole door, including closer, alignment and frame, rather than just swapping the lock and hoping.
  • Honest repair-or-replace advice: if a repair will do, we will not push replacement.
  • Careful with older doors, particularly period wood doors in Old Town where keeping original character matters to owners.

Commercial Door Hardware across Monrovia

Monrovia's business life is centered on Old Town Monrovia, where Myrtle Avenue is lined with small shops and restaurants in buildings of many different ages. Walk the strip near Library Park and you will see everything from original wood-and-glass entries to later aluminum storefronts, each with its own hardware quirks. For businesses in the 91016 ZIP code, that mix means a lockout, a sticky latch or a rekey after a staff change can look quite different from one door to the next.

Not all commercial hardware is on Myrtle Avenue. Along Huntington Drive and Foothill Boulevard, offices, service businesses and small retail units rely on doors that open all day, and the Metro A Line station brings steady foot traffic to the area. Older buildings throughout town may still carry original mortise and rim hardware, much like the 1900s-1930s Craftsman bungalows and Victorians around Old Town. We work with those older locks, preserving what can be kept rather than ripping out character that is hard to replace.

We also serve properties in North Monrovia and the foothill areas in 91017 and beyond, including Mayflower Village, and the approaches from I-210 and Mountain Avenue toward the canyon. Whether it is a restaurant near the Aztec Hotel stretch of Route 66, a shop in Old Town, or a small commercial property closer to the foothills, call (323) 997-8867 and we will come to you, any hour.

Commercial Door Hardware in Monrovia — FAQs

Do you repair commercial door hardware in Monrovia at night?
Yes. We are available 24/7 and fully mobile. If a storefront door will not lock or latch, call (323) 997-8867 and describe the problem so we can plan the right parts.
Can you work on aluminum-frame storefront doors?
Yes. We repair and replace hardware on aluminum-frame storefront doors, including locks, handles, pulls, closers and exit devices, working within the narrow stiles these doors have.
Do you handle old mortise locks?
Yes. Many older Monrovia buildings still have mortise hardware. We service and rebuild it where we can, and replace it when parts are worn out or unavailable.
Should I repair or replace my door hardware?
It depends on wear, parts availability and how the door is used. We inspect the full opening and tell you honestly whether a repair is enough or replacement is the better long-term choice.
Why does my storefront door drag or not latch?
Often it is not the lock. A worn closer, sagging hinge or pivot, or a misaligned strike can all cause it. We check the whole door so the real cause gets fixed.
Can you rekey my shop after an employee leaves?
Yes. We can rekey existing locks or replace hardware so old keys stop working. Call (323) 997-8867 to talk through how many doors are involved.
Do I need to come to your shop?
No. We are mobile only and have no storefront to visit. We come to your Monrovia business, whether in Old Town or elsewhere in the city.
How do I get a price for commercial hardware work?
Price depends on door type, hardware grade, the number of doors, and timing. Call (323) 997-8867, describe the door, and we will explain what affects the cost before work starts.
