Access control replaces the question of who has a key with the question of who should be allowed in, and when. For a Cerritos business, that can mean a keypad on a back-office door, card readers on a suite entrance, or key fobs for staff who open and close a storefront. Each can be added or removed without re-cutting a single key, which is a real relief when employees turn over or a tenant changes hands.

Cerritos has a large commercial footprint for a master-planned city: a regional mall, the dealership row at Cerritos Auto Square, and office and retail centers along South St, Del Amo Blvd and Bloomfield Ave. Many of these buildings use aluminum-storefront doors and master-keyed commercial hardware, and that hardware shapes what kind of access system will actually work. A reader that suits a solid office door may not suit a narrow-stile glass door.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit. We come to your site, look at the doors, and install a system sized to how your business really operates, not a package that sounds impressive but goes unused.

How it works in Cerritos

  1. 1

    Talk through the doors and the people

    We start by learning which entrances need control, who uses them, and at what hours. A front door for customers, a stockroom for a few employees and a manager's office all call for different answers. Call (323) 997-8867 any time, since we operate around the clock.

  2. 2

    Look at the door, frame and power

    We come to your location and examine each door: the material, the frame, the existing lock or strike, and where power and wiring can run. Aluminum storefront doors, wood office doors and steel service doors each have their own limits and options.

  3. 3

    Choose keypad, card or fob

    Keypads suit small teams and low-turnover spaces. Cards and fobs suit larger groups where you want to deactivate one person without affecting others. We explain the tradeoffs plainly and help you pick what matches your habits and budget.

  4. 4

    Install and test the hardware

    We mount the reader or keypad, fit the electric strike or lock, connect the controller and confirm the door still latches, releases and secures correctly. Fire and egress needs are kept in mind so that people can always exit.

  5. 5

    Enroll users and set rules

    We program codes, cards or fobs for your staff and set any schedules you want, such as limiting a door to business hours. You leave knowing how to add and remove people yourself.

  6. 6

    Walk-through and follow-up

    Before we leave, we run through each door with you and hand over the credentials. If management changes later or you add a door, we can come back and extend the system.

What affects the price

  • Number of doors being controlled, since each entrance needs its own reader, lock hardware and wiring.
  • Door and frame type, because aluminum storefront, hollow metal and wood doors call for different strikes and mounting methods.
  • Credential type: keypad, card or fob, and how many users need to be enrolled.
  • Wiring and power conditions, including how easily cable can be run to the door and controller.
  • Whether existing hardware can be reused or needs replacing, such as an old master-keyed lockset.
  • Extra features like scheduling, multiple access levels or after-hours installation.

Why Cerritos chooses us

  • Fully mobile service: we come to your Cerritos business instead of asking you to bring anything to a shop.
  • Available 24/7, so a security gap after a break-in or staff change does not have to wait for business hours.
  • In business since 1987, with deep experience in both traditional commercial locks and electronic systems.
  • We understand master-keyed commercial hardware and can integrate or transition from it, which matters in retail and office centers.
  • We recommend only what your doors and staff actually need, and we explain the tradeoffs rather than upselling.
  • Owner-led, with David Shar overseeing the work.

Access Control across Cerritos

Cerritos businesses cluster in a few distinct areas, and each has its own access needs. In the Los Cerritos Center district, retail tenants often change management or staff, and a card or fob system makes it easy to deactivate lost credentials without re-keying every door. Around Cerritos Towne Center and the civic area near the Cerritos Library, the Cerritos Center for the Performing Arts and the Sculpture Garden, offices and service entrances often need controlled access for staff and vendors.

Cerritos Auto Square brings its own concerns: dealership offices, parts areas and service entrances where key control matters and many people come and go. Keypads or fobs on back-of-house doors can keep inventory and records areas limited to the right team. Businesses with a 90703 address along South St, Del Amo Blvd or Bloomfield Ave, or just off the SR-91 and I-605, can all be reached by our mobile service.

Much of the city was built out in the 1970s, so some commercial buildings still carry older hardware that predates modern access control. We assess what is there, tell you honestly what can be kept, and install a system that fits. Call (323) 997-8867 to schedule.

Access Control in Cerritos — FAQs

What types of access control do you install in Cerritos?
We install keypad, card and fob systems for business entrances. We help you choose based on your doors, your staff size and how often people change. Call (323) 997-8867 to discuss your site.
Can access control work on aluminum storefront doors?
Yes, but it takes the right hardware. Narrow-stile storefront doors need readers and locks designed for those frames. We inspect the door first and recommend a fit that works.
Is a keypad or a fob system better for my business?
Keypads are simple and good for small teams. Fobs and cards let you cancel one person's access without changing anything for everyone else, which suits larger or higher-turnover staff.
Do you offer 24/7 service?
Yes. We are 24/7 and fully mobile, so you can call (323) 997-8867 at any hour, including after a break-in or when a key goes missing.
We have new management at our retail space. Can you help?
Yes. We can rekey, update master-keying or install access control so past credentials no longer work. This is a common need for tenants in shopping centers.
Will the system still let people exit safely?
Safe exit is a priority. We install hardware so that people can leave when needed, and we go over how each door behaves before we finish.
Do I need a storefront visit to get started?
No. We are mobile only and come to you. Call (323) 997-8867 and we will arrange a time to look at your doors.
Can I add or remove users myself later?
In most systems, yes. We show you how to enroll and remove codes, cards or fobs during the walk-through, and we are available if you need help later.
