A smart lock sounds simple: swap the deadbolt, pair an app, done. In Altadena it rarely is. The community has a wide mix of doors, from 1910s to 1940s Craftsman bungalows with old, sometimes repaired, door slabs, to Spanish Colonial entries with heavy wood and decorative hardware, to mid-century homes with their own quirks. Add the new construction rising after the January 2025 Eaton Fire, and no two installs are alike.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our team bring that experience to every smart lock job. We are mobile only, with no storefront, so the work happens at your door. We check the door, the bore holes, the latch and the strike before we recommend a lock, because a good smart lock on a poorly aligned door will still frustrate you.

Whether you are a homeowner in Janes Village who wants keypad entry without losing the character of an older home, a family rebuilding who wants a clean, keyed-alike setup from day one, or a contractor who needs controlled access to a jobsite, we install the hardware, set it up properly and show you how to use it. We also troubleshoot smart locks that have stopped responding, lost their pairing or are draining batteries.

How it works in Altadena

  1. 1

    Talk through your goals

    Call (323) 997-8867 and tell us what you want: keypad only, app control, auto-lock, shareable codes for family or workers. We ask about the door, the current lock and whether you have reliable Wi-Fi near the entry.

  2. 2

    Inspect the door and hardware

    On site, we look at door thickness, bore size, backset, latch condition and how well the door closes into the frame. Older Altadena doors that have swelled, shifted or been repainted many times often need small corrections first.

  3. 3

    Choose a lock that fits the door and the household

    We help you choose between a full keypad deadbolt, a smart retrofit that keeps your existing key, or a lever-style lock for a different door. We favor what suits the way you live over what has the longest feature list.

  4. 4

    Install and align

    We remove the old lock, fit the new one, and make sure the bolt throws smoothly into the strike without forcing. Smart locks put extra load on motors and batteries, so alignment matters more than it does with a plain deadbolt.

  5. 5

    Set up codes, app and settings

    We program user codes, pair the lock with your phone or home system where applicable, set auto-lock behavior and confirm everything works from both sides of the door.

  6. 6

    Walk-through and backup plan

    Before we leave, we show you how to change codes, replace batteries and use the backup key or emergency power option. You should never be locked out because a battery ran low.

What affects the price

  • The type of lock chosen: a basic keypad deadbolt, a Wi-Fi or app-connected model and a retrofit unit differ in hardware cost and setup time.
  • Door condition: a door that is warped, misaligned or needs new bore holes or a repaired edge takes more work than a clean, standard prep.
  • The number of locks: outfitting a whole rebuild or several entries with matching or keyed-alike hardware is scoped differently than a single front door.
  • Integration needs: connecting to an existing smart home system, hub or camera setup adds configuration time.
  • Timing and location: after-hours calls and hillside or gated properties can affect the scope of the visit.
  • Extras like rekeying other locks, lockboxes for contractors or a simple master-key system, which we quote once we know what you need.

Why Altadena chooses us

  • Fully mobile and available 24/7, so installation and troubleshooting happen at your door with no shop visit.
  • In business since 1987, with experience across older wood doors, modern prehung units and commercial hardware.
  • We check the door first. Many smart lock complaints trace back to alignment, not the electronics.
  • We can combine smart locks with traditional work: rekeying, keyed-alike sets, master-key systems and contractor lockboxes on one visit.
  • We explain batteries, backup keys and code management plainly, so you are not dependent on us after the job.
  • Honest recommendations. If a simple keyed deadbolt suits a particular door better, we will say so.

Smart Lock Installation across Altadena

Altadena's housing stock shapes smart lock work here. In Janes Village, many Craftsman and period bungalows have original or long-patched doors, and the goal is often to add keypad convenience without damaging the look of the entry. Spanish Colonial and mid-century homes near Altadena Drive and Lake Ave bring their own door sizes and hardware styles, so we measure before we promise a fit.

Since the January 2025 Eaton Fire, a lot of our current work is on rebuilds. For homes going up in 91001 and 91003, we can supply and key new locksets, set up keypad or smart entry for the finished home, and use contractor lockboxes to secure the jobsite while construction is underway. On surviving homes, heat and soot can leave hardware sluggish or seized, so we often assess whether an existing lock should be freed and rekeyed or replaced with a smart model.

We also work with larger hillside lots near Christmas Tree Lane on Santa Rosa Avenue, the Altadena Country Club and The Meadows, where gates, side-yard doors and detached structures may all need attention. Whether you are near Charles White Park, Farnsworth Park or the Cobb Estate and Sam Merrill Trailhead, or off Lincoln Ave, Fair Oaks Ave or Woodbury Rd, we come to you.

Smart Lock Installation in Altadena — FAQs

Can you install a smart lock on an older Altadena Craftsman door?
Usually yes. We check the thickness, bore size and condition of the door first. Sometimes a retrofit that keeps your existing deadbolt exterior is a better choice for an older door. Call (323) 997-8867 and we can talk through it.
Do you offer smart lock installation at night or on weekends?
Yes. We are 24/7 and fully mobile, so we can install or troubleshoot a lock when it suits you. Call (323) 997-8867 any time.
My smart lock stopped working. Can you fix it?
Often, yes. Common causes include dead batteries, lost pairing, a misaligned bolt or a door that has shifted. We diagnose on site and either repair, reset or replace as needed.
Can you set up locks on a home rebuilt after the Eaton Fire?
Yes. We can supply and key new locksets, set up keypad or smart entry, and arrange a simple master-key system. We can also provide contractor lockboxes to secure the jobsite during construction.
Will I still have a physical key?
It depends on the model. Many smart locks keep a key override, while some are keypad only. We explain the options and recommend a backup plan so you are never locked out.
Do you work with smart home systems?
We can pair locks with common apps and compatible systems. Tell us what you use when you call (323) 997-8867 so we bring the right hardware.
Can you give different codes to family, guests and contractors?
Yes. Most smart and keypad locks support multiple user codes. We set them up and show you how to add, change or delete them so you control who has access.
My deadbolt seized after the fire. Do I need a smart lock?
Not necessarily. Soot and ash can seize cylinders, and many can be freed and rekeyed. If the lock is too damaged, we can replace it with a standard or smart model, whichever you prefer.
