Sierra Madre is a small foothill town, and its businesses reflect that. Shops, cafes, offices and studios around Kersting Court and along Sierra Madre Blvd often occupy older buildings with doors that were never designed for electronic hardware. A metal key that has been copied a dozen times is still how many of them are secured. Access control replaces that with keypad codes, cards or fobs that you can issue, change and cancel without calling anyone to rekey a cylinder.

Our work here is installation: choosing the right credential type for how your staff actually come and go, fitting the reader and lock hardware to your door, and setting the system up so you control who has access. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how differently a historic storefront and a modern office suite need to be handled.

We are fully mobile. There is no showroom to visit; we bring the hardware and tools to your entrance, look at the door, frame and wiring situation in person, and talk through options before anything is drilled. If you are dealing with an urgent problem, such as a former employee who still has a key, we are available around the clock at (323) 997-8867.

How it works in Sierra Madre

  1. 1

    Talk through your entrance and your people

    We start with how the door is used: who needs access, at what times, and how often staff change. A small cafe with part-time employees has different needs than an office with a handful of long-term tenants. This conversation decides whether a keypad, cards, fobs or a combination makes sense.

  2. 2

    Inspect the door, frame and surroundings

    We come to your location and examine the door material, frame condition, existing lockset, and where power and wiring could reasonably run. Older Sierra Madre storefronts can have wood frames, glass doors or unusual hardware, and we point out any limits honestly before recommending a system.

  3. 3

    Choose hardware that suits the door

    We recommend a reader type and lock style, such as an electric strike, electrified lockset or standalone keypad lock, that fits the door and the way it must operate, including safe exit. We explain what each option does and does not do so you can decide with clear information.

  4. 4

    Install and integrate with the existing door

    We mount the hardware, make any needed door or frame preparation, and connect power and control components. We work to keep the look of the entrance tidy, which matters in a village-style downtown where storefront appearance counts.

  5. 5

    Program credentials and test thoroughly

    We set up codes, cards or fobs, test each one, and confirm the door locks and releases correctly, including from the inside. We check that the door closes and latches properly every time, since that is where many installs fail.

  6. 6

    Hand over and show you how to manage it

    We walk you or your manager through adding and removing users, changing codes and handling a lost credential. You leave knowing how to run the system yourself, and you can call (323) 997-8867 if questions come up later.

What affects the price

  • Number of doors being controlled, since each entrance needs its own reader and lock hardware.
  • Credential type: simple keypad codes, proximity cards or key fobs have different hardware and setup requirements.
  • Door and frame condition and material, including whether an older wood, glass or metal door needs preparation or reinforcement.
  • Lock hardware choice, such as an electric strike versus an electrified lockset or standalone keypad lock.
  • Wiring and power requirements, including how difficult it is to run cable in an older building.
  • Number of users and features, such as scheduled access or separate codes for individual staff, and whether the job is needed after hours.

Why Sierra Madre chooses us

  • Fully mobile service: we come to your entrance and assess the actual door rather than quoting from a catalog description.
  • In business since 1987, with owner David Shar directly involved in the work and standards.
  • We are a locksmith first, so we understand the mechanical side of the door, the latch and the frame, not just the electronics.
  • Honest recommendations: if a simple keypad lock does the job, we will say so instead of steering you to a bigger system.
  • Experience with older buildings and non-standard doors, which matters in a town of early-1900s structures.
  • Available 24/7 by phone at (323) 997-8867 for urgent security needs, including securing an entrance after a staff change.

Access Control across Sierra Madre

Sierra Madre's business life centers on the compact village core. Around Kersting Court in Downtown Sierra Madre, small shops and cafes share a walkable setting with buildings that date back many decades. Doors here may be glass, wood-framed or fitted with older hardware, so we look closely at what the entrance can safely support before choosing a reader or strike. Businesses in ZIP code 91024 often want something unobtrusive that fits the character of the street.

The town also extends up toward Sierra Madre Canyon, where narrow, steep lanes shape how work gets done. For small offices, studios or home-based businesses in the canyon and in ZIP code 91025, we plan for carrying tools from where the van can park and for doors that are not standard sizes. Many properties in the area are old, and some still have original mortise locks, so we are careful to discuss options that respect the building.

We reach Sierra Madre via Sierra Madre Blvd, Baldwin Ave, Michillinda Ave and Sierra Madre Villa Ave, with the I-210 Foothill Freeway nearby. Whether your business sits near Mary's Market, close to the trailheads for Bailey Canyon Wilderness Park and the Mount Wilson Trail, or tucked among the cottages near the wisteria vine, we come to you. Call (323) 997-8867 any time.

Access Control in Sierra Madre — FAQs

What types of access control do you install for Sierra Madre businesses?
We install keypad, card and fob systems for business entrances. Which one fits depends on your staff, how often people change, and your door. Call (323) 997-8867 and we can talk through the options.
Can access control be added to an older storefront near Kersting Court?
Often yes, but it depends on the door and frame. Older wood or glass doors may need preparation or a specific type of lock hardware. We inspect the entrance in person and tell you honestly what will work.
Do I need a keypad, cards or fobs?
Keypads are simple and need nothing to carry, but codes can be shared. Cards and fobs let you cancel one person's access without affecting others. We help you weigh these based on your team size and turnover.
Will the door still open from the inside in an emergency?
Safe exit is a core part of how we plan and test every installation. We configure the hardware so people can leave freely, and we verify that during testing before we finish.
Can you work on a business in Sierra Madre Canyon?
Yes. We are mobile and serve the canyon area too. Narrow lanes may mean we park below and carry equipment up, which we plan for in advance. Call (323) 997-8867 to schedule.
What happens if an employee leaves and still has a key?
With access control you can remove that person's code or credential instead of rekeying every lock. If you are still on traditional keys, we can also rekey cylinders as a stopgap while planning an upgrade.
Is there a shop I can visit to see the systems?
No, Crenshaw Lock Company is fully mobile with no storefront. We bring the hardware to your location, assess the door there, and walk you through the options on site.
Do you offer 24/7 service for access control issues?
Yes, we are available 24/7. If a system fails or you need to secure an entrance urgently, call (323) 997-8867 and we will help determine the next step.
