Access control replaces the question of who has a key with a simpler one: who should be allowed through this door, and when. For a business in Altadena, that might be a keypad on a back office door, a card reader on a shared suite entrance, or fobs for a team that comes and goes at different hours. Instead of rekeying every time someone leaves, you disable one credential and move on.

Altadena is in a period of rebuilding after the January 2025 Eaton Fire, and that shapes the commercial work here. New and rebuilt spaces are being outfitted from scratch, which is the easiest time to plan access control well: the door hardware, the power, and the wiring can all be decided together rather than patched in later. Existing businesses along corridors like Lake Ave and Fair Oaks Ave may be retrofitting older doors, where the frame and hardware matter just as much as the reader.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar. We are mobile only, with no storefront, so every assessment and installation happens at your door. We aim to recommend what fits your entrance and your budget rather than the biggest system we could sell.

How it works in Altadena

  1. 1

    Talk through the entrance and who needs access

    We start by learning about the door, the type of business, how many people need entry, and whether schedules matter. A small office with a handful of staff needs something very different from a multi-tenant building. Call (323) 997-8867 to begin.

  2. 2

    Assess the door, frame and power

    We come to the site and look at the door material, the frame, the existing lock, and where power and wiring can run. Older Altadena buildings sometimes have worn frames or unusual hardware that affect what can be installed cleanly.

  3. 3

    Choose keypad, card or fob credentials

    Keypads are simple and need no cards to lose. Cards and fobs give you individual credentials that can be turned off one at a time. We explain the tradeoffs plainly and help you pick the approach that suits how your team actually works.

  4. 4

    Install the hardware

    We mount the reader or keypad, fit the electric strike or lock hardware, and run the wiring and power. On a new build or rebuild, we can coordinate with the contractor so the door is prepared correctly before finishes go in.

  5. 5

    Program users and test the door

    We set up the credentials, test every function, and confirm the door secures properly when closed. We also check that the door still allows safe exit, which matters for any business entrance.

  6. 6

    Walk you through managing it

    Before we leave, we show you how to add or remove users and what to do if a credential is lost. You should be able to run the system day to day without calling us for routine changes.

What affects the price

  • The type of system: a standalone keypad is a very different scope from card or fob readers managed for many users.
  • The number of doors and users, since each additional entrance adds hardware, wiring and programming.
  • Door and frame condition, because worn or non-standard doors may need repair or different hardware to work reliably.
  • Wiring and power requirements, including how difficult it is to run cable in the existing walls or in a new construction schedule.
  • Lock hardware choice, such as electric strikes versus electrified locks, and whether existing hardware can be reused.
  • Timing and site conditions, including after-hours work or coordination with a contractor on a rebuild.

Why Altadena chooses us

  • Fully mobile service: we work at your entrance, so we see the real door, frame and wiring conditions before recommending anything.
  • Available 24/7, which helps when a door must be secured the same day a business reopens or a break-in damages an entrance.
  • In business since 1987, with owner and lead tech David Shar involved in the work.
  • We recommend what fits the door and the budget, including simple keypads when that is genuinely enough.
  • We understand rebuild-era needs in Altadena, including coordinating door prep with contractors and keying new hardware.
  • We explain how to manage users yourself so you are not dependent on us for routine changes.

Access Control across Altadena

Altadena's commercial and mixed-use needs are tied closely to its recovery. Along Lake Ave, Lincoln Ave, Fair Oaks Ave and Altadena Dr, businesses are reopening, relocating or building new, and many are deciding on entrance security for the first time in years. In ZIP codes 91001 and 91003, we see everything from small offices and studios to rebuilt storefronts where fresh doors and frames make clean installation straightforward.

Residential neighborhoods such as Janes Village, The Meadows, the area around Christmas Tree Lane on Santa Rosa Avenue, and the streets near Altadena Country Club also have home-based businesses, contractor sites and larger properties with gates and outbuildings. During construction, jobsites often need controlled access, and we can help think through how a rebuild's entrances should be secured once the work is finished.

Whether your location is near Charles White Park, Farnsworth Park, or toward Woodbury Rd and the foothills near the Cobb Estate and Sam Merrill Trailhead, we come to you. Call (323) 997-8867 and we will talk through what your entrance needs.

Access Control in Altadena — FAQs

What kinds of access control do you install for Altadena businesses?
We install keypad, card and fob systems for business entrances. The right choice depends on how many people need access, how often it changes, and the door itself. Call (323) 997-8867 to talk it through.
Do you offer 24/7 service for access control?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile. For urgent situations like a damaged entrance, call (323) 997-8867 and we will discuss how to secure the door.
Do I need a keypad, cards or fobs?
Keypads are simple and avoid lost credentials, but a shared code is harder to track. Cards and fobs let you disable one person without affecting others. We help you weigh this for your situation.
Can access control be added to an existing door?
Often yes, but it depends on the door, frame and available wiring. We look at the entrance in person first. Older doors may need repair or different hardware to work reliably.
Can you work with a contractor on an Eaton Fire rebuild?
Yes. Planning access control during construction is easier than retrofitting later, since door prep and wiring can be coordinated. Call (323) 997-8867 to discuss timing with your contractor.
How is the price determined?
Price depends on the system type, number of doors and users, door condition, wiring needs and hardware choice. We do not quote without understanding the entrance, so we assess your site first.
Do you have a shop I can visit?
No. We are mobile only, with no storefront. We come to your business anywhere in Altadena, including ZIP codes 91001 and 91003.
What happens when an employee loses a card or fob?
With a card or fob system, you can disable that one credential and issue a new one without rekeying the door. We show you how to manage this during setup.
