San Marino is mostly residential, so its commercial doors are few and carry real weight. Along Huntington Drive and the Mission Street stretch, small offices, professional suites, shops and service businesses depend on doors that open smoothly, latch firmly and lock when the last person leaves. When a storefront closer drags, a push bar sticks, or a cylinder turns stiffly, the problem is usually the hardware rather than the door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile and available 24/7. We come to your door with tools and parts for the common hardware found on aluminum-frame storefronts and older mortise-lock doors, and we repair what can be saved before suggesting replacement.

Commercial hardware in a city like San Marino often has to meet two standards at once: dependable security and a look that suits the surroundings. A mismatched finish or a clumsy retrofit stands out in a community that values careful appearances. We take that into account when we recommend a repair, a replacement or a rekey, and we explain the options in plain language before any work begins.

How it works in San Marino

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what the door is doing: sticking, not latching, loose handle, keys binding, or a lock that no longer holds. Details such as storefront glass, aluminum frame, or a heavier wood door help us bring the right parts.

  2. 2

    Inspect the hardware on site

    We come to your location and look at the whole assembly: the lock or latch, strike, hinges or pivots, closer, handle or pull, and how the door sits in its frame. Many hardware complaints come from alignment or wear, not a failed lock.

  3. 3

    Explain repair versus replacement

    We tell you what we found and what your realistic options are. If adjusting, lubricating or replacing a single worn part solves it, we say so. If the hardware is past saving, we explain why and what a replacement would involve.

  4. 4

    Repair or replace the hardware

    We carry out the work at the door: swapping a cylinder, replacing a storefront latch or push bar, adjusting a closer, or servicing a mortise lock body. We match function and finish as closely as practical to the existing look.

  5. 5

    Rekey or re-pin if needed

    If keys have been lost or staff have changed, we can rekey the cylinders so old keys stop working and the whole set operates on a manageable number of keys.

  6. 6

    Test and hand over

    Before we leave, we cycle the door repeatedly, check the latch, deadbolt, closer and alignment, and confirm it locks and releases correctly. You get working keys and a clear explanation of what was done.

What affects the price

  • The type of door and frame: aluminum storefront, hollow metal, or solid wood with a mortise lock each call for different parts and labor.
  • Whether the existing hardware can be repaired or must be fully replaced, including how many components are worn.
  • Hardware grade and finish, including high-security cylinders or finishes chosen to match nearby fixtures.
  • The number of doors and cylinders involved, especially if you want everything rekeyed to one key system.
  • Whether the work is urgent after-hours service, such as a door that will not secure the business overnight, or can be scheduled.
  • Availability of parts for older or unusual mortise hardware, which may need sourcing or adapting.

Why San Marino chooses us

  • Fully mobile service: we work at your door and have no storefront, so there is nothing to drop off or wait for.
  • Available 24/7, which matters when a business door cannot be locked and the premises are exposed.
  • In business since 1987, with David Shar as owner and lead technician.
  • Comfortable with both modern aluminum-frame storefront hardware and older mortise locks, a useful mix for San Marino's older buildings.
  • We repair first when repair makes sense, and we explain our reasoning instead of pushing replacement.
  • We pay attention to finish and appearance so new hardware suits the building, not just the door.

Commercial Door Hardware across San Marino

San Marino's commercial life is modest and concentrated. Huntington Drive and the Mission District around Mission Street hold the small businesses, offices and services that residents use daily, and these doors see steady traffic. In ZIP code 91108, a storefront door that sticks or a lock that fails affects customers and staff the same day, which is why round-the-clock mobile service is useful here.

The surrounding city shapes the work. Much of San Marino was built in the 1920s and 1930s in Spanish Colonial, Tudor and Georgian styles, and that period character carries into how people think about doors and hardware. Near the Huntington Library, Art Museum and Botanical Gardens, and around Lacy Park and Crowell Public Library, there is a strong expectation that things look well kept. We keep that in mind when choosing finishes, and we can work with older mortise hardware that was made to last.

We reach businesses along Huntington Drive, Sierra Madre Boulevard, San Gabriel Boulevard, Del Mar Avenue and Los Robles Avenue. Whether you run a small office near the Huntington Library district or a shop in the Mission District, call (323) 997-8867 and we will come to you. The same crew also does residential rekeying and high-security cylinder upgrades for the area's period estates, so we know how older hardware behaves.

Commercial Door Hardware in San Marino — FAQs

What kinds of commercial door hardware do you repair in San Marino?
We repair and replace storefront, aluminum-frame and mortise door hardware, including locks, latches, cylinders, push bars, pulls, handles and closers. Call (323) 997-8867 and describe your door so we can bring suitable parts.
Do you offer 24/7 service for businesses?
Yes. We are available 24/7 and fully mobile. If a business door will not lock or latch overnight, call (323) 997-8867 any time and we will work with you to secure it.
Do I have to bring anything to a shop?
No. We are mobile only and have no storefront. We do the work at your door, so you never need to remove hardware or take anything anywhere.
Can you fix an old mortise lock instead of replacing it?
Often, yes. Mortise lock bodies from older buildings can frequently be cleaned, adjusted or fitted with a new cylinder. If a part is too worn, we will explain why replacement is the better choice.
Can you rekey commercial doors after an employee leaves or keys are lost?
Yes. We can rekey cylinders so old keys no longer work, and we can often bring several doors onto one key. Call (323) 997-8867 to talk through what you need.
My storefront door is hard to close or does not latch. Is the lock to blame?
Not always. Misalignment, a worn closer, loose hinges or a shifted strike plate are common causes. We inspect the whole assembly so you only pay for the actual fix.
How is the price determined?
It depends on the door and frame type, whether we repair or replace, hardware grade and finish, the number of doors, and whether the visit is urgent. We explain the options before starting work.
Do you serve all of San Marino?
Yes, including the Huntington Drive and Mission District commercial area, the Huntington Library district and the Lacy Park neighborhood, ZIP code 91108. Call (323) 997-8867 to ask about your location.
