A commercial door works harder than almost any other part of a building. In Cerritos, that means retail doors at Los Cerritos Center opened and closed all day, showroom and service entrances along Cerritos Auto Square, and office suites tucked into centers off South St, Del Amo Blvd and Bloomfield Ave. When the hardware wears out, the problem is rarely just inconvenience. A door that will not lock leaves inventory exposed overnight, and a door that will not release can be a safety concern.

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, so there is no storefront to visit. We bring the tools and a working knowledge of commercial hardware to your door, diagnose what is actually failing, and repair it where repair makes sense or replace it where it does not.

Our commercial door hardware work covers the types of doors you see all over Cerritos: aluminum-frame storefront doors with narrow stiles, mortise lock sets common in older office buildings, panic and exit devices, door closers, hinges, strikes and handles. We are available around the clock, which matters when a failed lock cannot wait until Monday morning.

How it works in Cerritos

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what the door is doing: not latching, key sticking, handle loose, closer slamming, or lock fully failed. Tell us whether it is glass storefront, aluminum frame, or a solid door with a mortise lock. That helps us bring suitable parts.

  2. 2

    Secure the premises first

    If the business is currently open to the public or unsecured, our first priority is making the door safe to leave. Sometimes that is a temporary fix, and sometimes it is a fast replacement of the failed part.

  3. 3

    Inspect the whole door assembly

    Many hardware complaints trace back to something other than the lock. A sagging door, worn hinges, a misaligned strike or a weak closer can all cause a lock to bind. We check the full assembly so we are not just replacing a part that was working.

  4. 4

    Repair or replace with the right hardware

    We repair what can be repaired and replace what cannot. For aluminum storefronts, that includes working within narrow stile limits. For mortise hardware, we match the lock body and trim to your existing door preparation when possible, and we can rekey or master-key as part of the job.

  5. 5

    Test and hand over keys

    We cycle the door repeatedly, check latching, key operation and closer speed, and confirm the door secures properly. You receive all keys, and we explain what we changed so your manager or property contact has a clear record.

What affects the price

  • The type of door: aluminum storefront, hollow metal, wood or glass each call for different hardware and labor.
  • Whether the existing hardware can be repaired or the lock body, trim, closer or exit device needs full replacement.
  • The grade and style of hardware chosen, such as standard commercial grade versus heavier-duty or specialty mortise sets.
  • Whether rekeying, master-keying or additional keys are included, especially for new tenants or management changes.
  • The number of doors involved, since a multi-door job can be handled in one visit.
  • The time of the call, since after-hours and emergency service differ from scheduled daytime work.

Why Cerritos chooses us

  • Operating since 1987, with owner David Shar leading the work, so commercial hardware problems are familiar rather than new.
  • Fully mobile and available 24/7, so a failed storefront lock does not have to wait for business hours.
  • We look at the whole door, including hinges, closer and strike, instead of swapping a lock that was not the real issue.
  • Comfortable with aluminum-frame storefronts and mortise hardware, which are common on Cerritos retail and office properties.
  • Hardware repair, rekeying and master-keying can be handled together, which helps when management or tenants change.
  • No storefront and no pressure: we come to you, explain options plainly and let you decide.

Commercial Door Hardware across Cerritos

Cerritos is a master-planned city that grew from the Dairy Valley days into a major retail and commercial center. That shows in its commercial buildings. Around the Los Cerritos Center district, tenants deal with constant foot traffic on storefront doors, and new management or a changing tenant often means the hardware needs rekeying or master-keying. Cerritos Auto Square brings its own needs, with showroom entrances, service doors and office doors that see heavy daily use.

Office and retail centers along South St, Del Amo Blvd and Bloomfield Ave rely on aluminum-storefront doors and master-keyed hardware that can wear out over years of use. Near Cerritos Towne Center, and around civic landmarks such as the Cerritos Library, the Cerritos Center for the Performing Arts and the Sculpture Garden at the Civic Center, doors tied to public-facing and event-driven buildings take steady wear too. With SR-91 and I-605 close by, we can reach businesses throughout the 90703 ZIP code and beyond.

Whether you manage a retail suite, run a dealership office or lease space in a Cerritos center, call (323) 997-8867. We are mobile, available day or night, and happy to look at the door before you commit to anything.
