An access-control system replaces the question of who still has a copy of the key with a simpler one: who is allowed in, and when. For a Duarte business, that might be a keypad on a back office door, card readers on a suite entrance, or key fobs for staff who come and go at odd hours. The right setup depends on the door, the people using it, and how much you want to track.

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 locksmith work. We are a mobile-only operation. There is no storefront to visit; we bring the tools and hardware to your location, look at the actual door and frame, and install the system on site.

Duarte has a mix of businesses that each have different needs: medical and professional offices around the City of Hope area, shops and small offices along Huntington Drive, and apartment and condo properties with shared entrances. We try to match the system to the real use of the door rather than selling more technology than you need.

How it works in Duarte

  1. 1

    Talk through the entrance and your goals

    We start with a call to (323) 997-8867 or a visit to the site. We ask who uses the door, how many people need access, whether staff turn over often, and whether you need a record of entries or just a better way to control keys.

  2. 2

    Inspect the door, frame and power options

    On site we look at the door material, the frame, the existing lock, and how the door closes. Whether it is a wood office door, a metal storefront door or a glass entry affects which hardware fits and how it is mounted.

  3. 3

    Recommend a keypad, card or fob system

    Keypads suit small teams and low-turnover doors. Cards and fobs make it easy to deactivate one person without changing everyone else. We explain the tradeoffs plainly and let you choose.

  4. 4

    Install and test the hardware

    We mount the reader or keypad, set up the lock or electric strike, and make sure the door still latches, closes and opens correctly. We test it repeatedly before we call it done, including how it behaves in a power interruption.

  5. 5

    Program users and walk you through it

    We set up codes, cards or fobs for your team and show you how to add or remove users. You should leave knowing how to manage the system yourself.

  6. 6

    Follow-up support

    If a reader acts up or you need to add staff later, call (323) 997-8867. Because we are available 24/7, a problem at a late-night shift change does not have to wait for business hours.

What affects the price

  • The type of system: a standalone keypad is a different project from card or fob readers tied to several doors.
  • The number of doors and users, since each added entrance and each credential adds hardware and programming time.
  • Door and frame condition and material, which determines whether we can mount directly or need modifications.
  • Whether the door needs an electric strike, magnetic lock or other powered hardware and the wiring that goes with it.
  • Fire-code and egress requirements, which can limit how a door may be locked and affect hardware choice.
  • Timing of the visit, such as an after-hours or urgent install versus a scheduled one.

Why Duarte chooses us

  • Fully mobile: we install at your entrance, with no shop trip and no leaving your door unsecured.
  • In business since 1987, with David Shar as owner and lead technician.
  • Available 24/7, so installs and emergency repairs can fit around your hours.
  • We recommend the simplest system that solves your problem instead of upselling.
  • We teach you to manage users yourself rather than leaving you dependent on us.
  • Locksmith-level understanding of door hardware, so the electronic parts work with a door that actually latches well.

Access Control across Duarte

Duarte sits at the foothills along the I-210 corridor, and its commercial life is spread out. Medical and professional offices cluster near the City of Hope campus in the 91010 area, while smaller shops, offices and service businesses line Huntington Drive (Route 66) and run along Mountain Avenue and Buena Vista Street. Many are in older low-rise buildings where the doors and frames have seen decades of use, so we check the hardware condition before choosing a system.

Residential neighborhoods such as Butler and Cotter, with their 1950s and 1960s ranch and tract homes, also include home offices and small businesses that want better control than a shared key. Near the A Line, newer condos and apartments have shared entrances where fobs or keypads can help property managers handle residents coming and going. Farther up toward Royal Oaks and the Fish Canyon area, custom foothill properties and 91009 addresses sometimes need gate or outbuilding access that we can discuss as part of a larger plan.

Whether you are near Encanto Park, the Duarte Recreational Trail along the San Gabriel River, or just off the I-605, we come to you. Call (323) 997-8867 and we will talk through what makes sense for your entrance.

Access Control in Duarte — FAQs

What kinds of access control do you install for Duarte businesses?
We install keypad, card and fob systems for business entrances. Keypads suit small teams, while cards and fobs make it easier to add or remove individual users. Call (323) 997-8867 and we can help you decide.
Do I need access control or just a better lock?
If a few people use the door and rarely change, a quality lock may be enough. If staff turn over, you have many users, or you want to avoid rekeying every time someone leaves, access control is often worth considering.
Can you install access control on an older door?
Often yes. We inspect the door and frame first. Older doors sometimes need adjustments so the lock latches reliably, and we will tell you what is needed before we start.
Are you a shop I can visit?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your business in Duarte and install on site.
Do you work after hours?
Yes, we are available 24/7. Call (323) 997-8867 to schedule an install outside your normal business hours or to ask about an urgent issue.
What happens if someone leaves the company?
With cards, fobs or individual codes, we show you how to deactivate that person's access without changing everyone else's. That is a major advantage over shared keys.
Can access control work for a medical or professional office near City of Hope?
Yes. Offices with staff on varied schedules benefit from controlled entry. We will review the door, who needs access, and any code requirements before recommending a system.
How is the price determined?
It depends on the system type, the number of doors and users, the door and frame condition, any powered hardware and wiring, and code requirements. We explain what drives the cost before work begins.
