A key that has been copied a dozen times, handed to a former employee, or lost in a drawer is a weak way to control who walks into your business. Keypad, card and fob access control replaces that guesswork with credentials you can issue, change and cancel without re-cutting a single key. For Alhambra businesses, from a Main Street restaurant to an office suite off Valley Boulevard, that control can make daily operations simpler and more secure.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on practical, honest hardware work. We are fully mobile. There is no storefront to visit; we bring the tools and components to your location, look at the door you actually have, and recommend a system that fits it rather than a one-size-fits-all package.

Alhambra's commercial buildings vary a lot. Aluminum storefronts with narrow stiles, mixed-use buildings with apartments above retail, older masonry and wood-frame structures, and mid-century courtyard properties each present different mounting and wiring challenges. This page explains how an installation typically goes, what shapes the cost, and what to consider for your own entrance.

How it works in Alhambra

  1. 1

    Walk the entrance and talk through your needs

    We start by looking at the door, the frame, and how people actually use the entrance. A shop with a single front door and a back alley exit has different needs than an office with staff arriving at different hours. We ask who needs access, when, and whether you want keypad codes, cards, fobs, or a combination.

  2. 2

    Check the door, frame and power options

    Aluminum storefront doors, hollow metal doors and wood doors all take hardware differently. We look at the stile width, the existing lock or panic device, fire-exit requirements, and where power and wiring can realistically run. This step determines whether an electric strike, a magnetic lock, or electrified hardware is the right choice.

  3. 3

    Recommend a system and confirm the plan

    Once we understand the door, we explain the options in plain language: how credentials are issued and removed, what happens during a power loss, and how the door behaves for emergency exit. You approve the plan before we begin work.

  4. 4

    Install the hardware and reader

    We mount the reader or keypad, install the locking hardware, run the necessary wiring, and connect the controller and power supply. We aim to keep the door looking clean and working smoothly, and we take care with storefront glass and frames so the finish is not damaged.

  5. 5

    Program credentials and test everything

    We set up your codes, cards or fobs, test each one, and check the door from both sides, including the free-egress side. We confirm the door latches properly and releases as intended.

  6. 6

    Walk you through daily use

    Before we leave, we show you or your manager how to add and remove users, change codes, and what to do if something stops working. You should be able to manage the system without calling us for every small change.

What affects the price

  • The number of doors being controlled, since each entrance needs its own reader, locking hardware and wiring.
  • The type of door and frame, such as aluminum storefront, hollow metal or wood, which affects the mounting method and hardware choice.
  • Which credential types you want: keypad codes, proximity cards, key fobs, or a mix of them.
  • How difficult the wiring run is, including distance to power, ceiling or wall access, and whether the building is older or mixed-use.
  • The locking method selected, such as electric strike, magnetic lock or electrified lever, and any fire or egress requirements for that door.
  • Whether you need extra features like multiple user groups, scheduled access times, or removal of existing hardware.

Why Alhambra chooses us

  • Fully mobile service: we come to your Alhambra business, assess the real door, and do the installation on site.
  • In business since 1987, with David Shar leading the work, so experience with a wide range of doors and buildings informs each recommendation.
  • Available 24/7, which matters when a break-in damage or a failed lock needs to be dealt with outside business hours.
  • We match the system to the door instead of pushing a standard kit, including narrow aluminum storefront stiles common on commercial streets.
  • We explain egress, power-failure behavior and credential management in plain terms so you understand what you are buying.
  • We also handle rekeying, broken key extraction and repairs, so one company can support your locks and your access system together.

Access Control across Alhambra

Alhambra's commercial life stretches across several distinct areas. Downtown Alhambra and the Main Street dining and entertainment corridor, near the Garfield Theatre, are full of restaurants, shops and mixed-use buildings with aluminum storefronts. Those doors often have slim frames, so reader and strike selection takes care. Businesses in ZIP code 91801 along Main Street and Valley Boulevard often want a simple, reliable way to give staff access without handing out copies of a key.

Further along Fremont Avenue and Atlantic Boulevard, and near the I-10 corridor, you find offices, clinics, workshops and the Alhambra office and retail campus. These properties tend to have multiple staff, deliveries and after-hours needs, which makes card or fob systems with individually removable credentials a practical fit. In ZIP code 91803, which includes areas toward the Airport Tract and Emery Park, we also see small commercial suites and multi-unit properties that benefit from controlled entry at shared doors.

Alhambra is known as the City of Homes, and neighborhoods like Bean Tract and Midwick Tract keep their historic character. Businesses and property managers operating near these areas, or in older buildings with original doors, often need an installation that is sensitive to the existing building. We plan the work so the entrance works well without unnecessary alteration. Whatever the building, call (323) 997-8867 and we will come to you.

Access Control in Alhambra — FAQs

What kinds of access control systems do you install in Alhambra?
We install keypad, card and fob systems for business entrances. Many Alhambra shops and offices choose keypads for simplicity, while larger staffs often prefer cards or fobs. Call (323) 997-8867 to discuss which fits your door.
Can access control be installed on an aluminum storefront door?
Yes, in most cases. Storefront doors have narrow stiles, so we choose slim readers and compatible hardware, and we check the frame before recommending a method. This is common on Main Street and Valley Boulevard.
Do you come to my business, or do I have to visit a shop?
We are fully mobile and have no storefront. We come to your Alhambra location and complete the installation there. You can reach us at (323) 997-8867 any time, day or night.
What happens to the door if the power goes out?
It depends on the locking hardware. Some setups unlock when power fails and others stay locked, and egress rules affect the choice. We explain how your door will behave before installation so there are no surprises.
How do I remove access for an employee who has left?
With a keypad, you change or delete that person's code. With cards or fobs, you deactivate the credential. This is a major advantage over keys, which cannot be recalled once copied.
Can you add access control to a door I already have?
Often yes. We inspect the existing door, frame and lock, then decide whether to adapt the hardware or replace parts. We aim to reuse what makes sense and tell you plainly when something needs replacing.
How much will access control installation cost?
It depends on the number of doors, the door and frame type, the credential style, the wiring needed, and the locking method. After seeing your entrance we can explain the factors in detail. Call (323) 997-8867 to get started.
Do you also rekey or repair locks at my business?
Yes. We handle rekeying, broken key extraction and lock repair alongside access control, so one call covers both. This is useful when you want to secure a space quickly before opening.
