A smart lock is a simple idea: no more hunting for keys, easy codes for family or guests, and in many cases a phone app that shows who came and went. In practice, the lock only works as well as the door it is mounted on and the setup behind it. A deadbolt that does not line up with the strike, a Wi-Fi signal that does not reach the front porch, or a code scheme nobody understands can turn a good product into a daily annoyance.

Crenshaw Lock Company has been working on locks in Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched keyless hardware go from a novelty to a normal upgrade. In San Dimas, where much of the housing is ranch-style single-family homes from the 1960s and 70s, we often start by checking how an older door and frame will take a modern electronic deadbolt, then fit the hardware so it operates smoothly and securely.

We are a fully mobile service. There is no storefront to visit; we bring the tools and hardware knowledge to your property, install the lock, program it, and walk you through everyday use so you are not left with a box of instructions and a blinking light.

How it works in San Dimas

  1. 1

    Talk through what you want

    We start with a call to (323) 997-8867. Tell us whether you want a keypad, a fob or phone-based lock, whether it needs to work with an app or hub you already use, and who needs access. That conversation helps us bring suitable hardware to your door.

  2. 2

    Check the door, bore and frame

    On arrival we look at the door thickness, existing holes, backset, strike plate and how the door closes. Older ranch-home doors often have settled slightly, and a lock that drags against the frame will wear out batteries and motors faster.

  3. 3

    Install the lock properly

    We remove the old hardware, fit the new deadbolt or handleset, align the latch and strike, and make sure the bolt throws fully without force. Tight, square mounting is what keeps electronic locks reliable.

  4. 4

    Program codes and connect it

    We set up your user codes, test the keypad, and pair the lock with an app, hub or voice assistant if you want that. If your Wi-Fi is weak at the door, we tell you plainly what that means for remote features.

  5. 5

    Walk through daily use

    We show you how to add and delete codes, what the low-battery warnings look like, and how to use the mechanical key backup if the lock offers one, so you feel confident before we leave.

  6. 6

    Troubleshoot and follow up

    Already own a smart lock that misbehaves? We also diagnose jamming, unresponsive keypads, pairing drops and alignment problems, and fix or replace what is actually causing them.

What affects the price

  • The lock itself: basic keypad deadbolts, app-connected models and lever-style handlesets differ widely in hardware and features.
  • Number of doors: a single front door is a different job than front, back and garage-entry doors that you want matched.
  • Condition of the door and frame: misaligned bores, worn strikes or a door that needs adjustment add work beyond the lock swap.
  • Whether you are replacing an existing lock or adding a new one where none existed, which may require drilling.
  • Setup depth: simple code programming is quicker than integrating with a hub, multiple users and an app.
  • Timing and location of the visit, including after-hours calls to larger rural lots outside the town center.

Why San Dimas chooses us

  • Fully mobile and available 24/7, so installation can happen at your property instead of you carrying a lock to a shop.
  • In business since 1987, with hands-on experience in traditional hardware, which matters when fitting electronics to older doors.
  • Owner and lead technician David Shar stands behind the work rather than handing it off to a call center.
  • We check door alignment first, because many smart lock complaints are really mechanical problems.
  • We explain limits honestly, such as weak Wi-Fi at a far-off gate or the need for a mechanical backup, instead of overselling features.
  • We can handle the broader lock picture too, from rekeying and padlocks to gates and outbuildings, so your smart lock fits a coherent setup.

Smart Lock Installation across San Dimas

San Dimas homes vary more than people expect. Many sit on ranch-style lots from the 1960s and 70s along streets off San Dimas Ave, Arrow Hwy and Foothill Blvd, where solid wood or older hollow-core doors may need careful fitting for an electronic deadbolt. In the Via Verde planned community on the southern hills, HOA-standard hardware and a uniform look often mean owners want a smart lock that matches existing finishes and handles, especially after buying a home and updating access.

Near San Dimas Canyon and Frank G. Bonelli Regional Park, larger lots, barns, outbuildings and gated drives bring different needs. A keypad on a side entry or workshop can be handy when several people share a property, but distance from the house router matters, so we talk through realistic connectivity. Downtown, along Bonita Ave in Old Town San Dimas, small retail and civic-style buildings may want keypad entry for staff or back doors without handing out many keys.

We serve ZIP code 91773 and the surrounding area from the I-210, SR-57 and Foothill corridors, whether you are near Puddingstone Reservoir, San Dimas Canyon Park or close to Raging Waters. Call (323) 997-8867 any time of day to talk about your door.

Smart Lock Installation in San Dimas — FAQs

Do you install smart locks at homes throughout San Dimas?
Yes. We are fully mobile and come to homes, businesses and rural properties in San Dimas, including Via Verde, Old Town and the San Dimas Canyon area. Call (323) 997-8867 to discuss your door.
Can a smart lock fit my older ranch-style front door?
Usually, yes. Many 1960s and 70s doors accept standard electronic deadbolts, but we check thickness, bore holes and frame alignment first. If something needs adjusting, we tell you before we start.
Will my HOA in Via Verde care what lock I install?
Some HOAs have standards for exterior hardware or finishes. We recommend checking your association's rules first, and we can help choose a lock whose finish and style blend with your existing hardware.
Can you set up a keypad lock on a barn or gate?
For many outbuildings and gates, yes, depending on the structure and weather exposure. Distance from your Wi-Fi may limit app features, so we explain what will and will not work. Call (323) 997-8867 to describe the setup.
What if my smart lock stopped working?
Common causes include low batteries, a misaligned bolt, lost pairing or a faulty keypad. We diagnose the cause on site and repair or replace the lock as needed.
Do I still need a physical key?
Many smart locks include a mechanical key override, and we generally recommend having one. Some models are keypad-only, so we discuss backup options before installing.
Do you offer smart lock help outside regular business hours?
Yes, we operate 24/7 and are fully mobile. Call (323) 997-8867 if you are locked out of a smart lock or need help with an urgent install.
Can you add codes for family, guests or employees?
Yes. We program user codes during setup and show you how to add, change and remove them yourself, which is useful for family, house sitters or staff at a downtown business.
