Most businesses in San Dimas don't need a sprawling security installation. They need the right door controlled the right way: a back entrance that only staff can open, a supply room that stays restricted, a gate that lets the morning crew in without anyone handing out a ring of keys. Access control fills that need. Instead of copying metal keys that can walk off and never be tracked, you issue codes, cards or fobs that can be changed or switched off when someone leaves.

Crenshaw Lock Company has been serving Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how much a well-chosen system changes day-to-day life for a small business. We are a fully mobile operation. There is no storefront to visit; we come to your building, look at the door, the frame, the power situation and how your people actually move through the space, and then recommend something that fits.

San Dimas has an unusual mix of commercial settings: small retail and civic buildings in the western-themed downtown, offices and shops along Foothill Blvd and Arrow Hwy, and rural-flavored properties with outbuildings and gated drives. Each calls for different hardware, and we try to match the system to the property rather than push one product everywhere.

How it works in San Dimas

  1. 1

    Talk through the doors and the people

    Call (323) 997-8867 and tell us which entrances you want to control and who needs to get through them. Staff, vendors, cleaning crews and tenants often need different levels of access, and sorting that out first keeps the system simple.

  2. 2

    On-site look at the hardware

    We come to the property and examine each door: the material, the frame, the existing lock, the closer and where power can reach. Older storefronts, glass doors and wooden doors each affect which reader and lock type will work.

  3. 3

    Choose keypad, card or fob

    Keypads suit low-turnover spaces where codes are shared sparingly. Cards and fobs suit teams where you want to deactivate one person without disturbing everyone else. We explain the tradeoffs plainly and let you decide.

  4. 4

    Installation and wiring

    We mount the readers, install the electric strike or lock hardware, connect power and make sure the door still closes, latches and releases the way it should. We pay attention to fire and egress considerations so people can always exit.

  5. 5

    Programming and testing

    We set up user codes, cards or fobs, test every credential at each door, and confirm the lock behaves correctly after hours and during a power interruption.

  6. 6

    Walkthrough and handoff

    Before we leave, we show you how to add and remove users, change codes and handle a lost fob, so you aren't waiting on us for routine changes.

What affects the price

  • The number of doors or gates being controlled, since each entrance needs its own reader and lock hardware.
  • Door and frame type: a solid wood or metal door is different work than an aluminum storefront or glass door.
  • Credential type, whether keypad, card or fob, and how many users need their own credentials.
  • Wiring and power conditions, including how far the reader sits from a power source and whether walls or conduit are involved.
  • Whether you are replacing existing hardware or adding control to a door that has never had it.
  • Special requirements such as a gated drive, outdoor weather exposure or integration with an existing alarm or intercom.

Why San Dimas chooses us

  • Fully mobile and available 24/7, so installation can be scheduled around business hours rather than the other way around.
  • In business since 1987, with an owner-led approach and decades of experience across commercial doors of all ages.
  • We recommend the simplest system that solves your problem instead of upselling features you will not use.
  • Hands-on training at handoff so you can manage users yourself.
  • Familiar with the mix of older downtown storefronts and rural-style properties found around San Dimas.
  • Honest conversations about egress and fire-safety needs so doors stay compliant and usable.

Access Control across San Dimas

San Dimas businesses sit in a few distinct settings, and each shapes how access control gets done. In Downtown and Old Town San Dimas, the western-facade buildings along Bonita Ave are typically small retail and civic spaces, often with older doors and frames that need careful fitting. A keypad on a back-of-house door or a fob-controlled staff entrance can reduce the need to hand out keys without changing the look of the front. Businesses in ZIP code 91773 along San Dimas Ave, Arrow Hwy and Foothill Blvd tend to have a mix of storefront and office doors.

On the rural-flavored side of town, near San Dimas Canyon, San Dimas Canyon Park and Frank G. Bonelli Regional Park, properties often include barns, outbuildings and gated drives that have long relied on padlocks. For equestrian and horse-keeping operations, a keypad or fob at the gate can be easier than juggling keys among trainers, farriers and delivery drivers, though outdoor exposure and power access need to be planned carefully.

Many of our San Dimas customers also live in places like the Via Verde planned community, and some run home-based or small offices there, where HOA rules may affect what can be mounted on an exterior. Whether you are close to Puddingstone Reservoir, near the Raging Waters Los Angeles area, or just off the I-210, SR-57 or I-10, we come to you. Call (323) 997-8867.

Access Control in San Dimas — FAQs

What types of access control do you install in San Dimas?
We install keypad, card and fob systems for business entrances. During the on-site visit we help you choose based on how many people need access and how often those people change.
Is a keypad or a fob better for a small business?
A keypad is simple and works well when only a handful of people need entry. Fobs or cards are better when staff turnover is higher, since you can disable one credential without changing everything. Call (323) 997-8867 and we can talk through your setup.
Can you install access control on an older downtown storefront door?
Often yes. Older wood, metal or glass doors can usually be fitted with a suitable electric lock or strike, though we check the door and frame first to pick hardware that works properly.
Can access control be used on a gate or outbuilding?
Yes, in many cases. Gated drives and barns can use keypad or fob entry in place of a padlock, though weather exposure and power supply have to be planned. We assess the property before recommending anything.
Will people still be able to exit during a power outage?
Egress is a core part of any installation. We design doors so people can leave safely and talk through how the lock behaves if power is interrupted.
How is the price determined?
Pricing depends on factors like the number of doors, door type, credential style, wiring needs and whether hardware is new or replaced. We do not quote figures without seeing the doors, so call (323) 997-8867 to start the conversation.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your San Dimas location and do the work on site.
Can I manage users myself after installation?
Yes. We walk you through adding and removing users and changing codes before we leave, so everyday changes do not require a service call.
