Sierra Madre is not a town of cookie-cutter doors. Around the village core you find early-1900s Craftsman cottages, Victorians and bungalows, and up in Sierra Madre Canyon there are old cabins on narrow, steep lanes. A lot of these doors were built long before anyone imagined a keypad or an app-controlled deadbolt. Fitting a smart lock to one of them takes more than unboxing a kit and following the diagram.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. Smart lock work is a specialty service for us: we install, configure and troubleshoot keyless entry, keypad deadbolts and smart locks, and we help you decide which type actually suits the door in front of us. Sometimes that is a full smart deadbolt. Sometimes it is a keypad lever, and sometimes the honest answer is to keep a mechanical lock on a historic door and add keyless entry somewhere less delicate.

We are mobile only. There is no storefront to visit; we bring the tools, hardware knowledge and setup experience to you, any hour of the day or night. Whether you are a homeowner near the wisteria vine, a landlord handling tenant turnover, or a shop owner around Kersting Court who is tired of passing out keys, we can walk through the options with you and install the lock properly.

How it works in Sierra Madre

  1. 1

    Talk through the door and the goal

    Call (323) 997-8867 and tell us what you are trying to solve: no more spare keys, codes for guests or tenants, a lock your family can use easily, or a replacement for a failing device. We ask about the door type, age and any existing hardware so we arrive prepared.

  2. 2

    Inspect the door and existing hardware

    On site we check the door thickness, bore holes, edge preparation, latch and strike alignment. In Sierra Madre, that often means a century-old door with a worn or non-standard preparation, or a mortise lock that cannot simply be swapped for a modern deadbolt.

  3. 3

    Choose a lock that fits the door and your routine

    We go over keypad, smart deadbolt and app-connected options in plain language, including how each is powered, how you get in if the batteries die, and how it works with your Wi-Fi or phone. We will tell you if a device is a poor match for your door.

  4. 4

    Install and align the hardware

    We fit the lock, adjusting or modifying the door preparation only as needed, and make sure the bolt throws smoothly into the strike with no binding. A smart lock that fights a misaligned door will drain batteries and fail early, so alignment gets real attention.

  5. 5

    Set up codes, app and settings

    We program user codes, pair the lock with your phone or home system if you want that, and set up any auto-lock behavior. We then show you how to add and delete codes yourself, which matters for rentals and shared spaces.

  6. 6

    Test, hand over and troubleshoot

    Before we leave, we test the lock from inside and outside, with the door open and closed, and confirm you know the backup entry method. If you already own a smart lock that is misbehaving, we can troubleshoot pairing, calibration and battery issues on the same visit.

What affects the price

  • The type of lock: a basic keypad deadbolt, a smart deadbolt with app control and a more full-featured connected lock involve different hardware and setup effort.
  • Door condition and preparation: older Craftsman and cabin doors may need bore or edge adjustments, or may not suit a given lock at all, which changes the amount of work.
  • Whether you supply the lock or we do: bringing your own device is fine, but we may advise if it is wrong for the door, and sourcing hardware affects the total.
  • Number of doors and setup scope: several doors, matching codes across locks, or integrating with an existing smart home system add time.
  • Rekeying or replacing existing mechanical hardware first: if a worn lock or a mortise set must be addressed before keyless entry, that is additional work.
  • Time and access: after-hours calls and sites that require carrying tools a distance, like steep canyon lanes, can influence the quote.

Why Sierra Madre chooses us

  • Fully mobile and available 24/7, so installation and troubleshooting can happen when it suits you, not just during shop hours.
  • In business since 1987 under owner David Shar, which means familiarity with older doors and mechanical hardware, not just boxed consumer devices.
  • Honest recommendations: we will say when a smart lock is a bad fit for a historic or non-standard door and suggest alternatives.
  • We set up the software side as well as the hardware, including codes, app pairing and showing you how to manage users.
  • Mechanical and electronic skills under one roof, so we can rekey, repair or replace the traditional lock and then add keyless entry in the same visit.
  • We plan for the power-failure case, explaining battery warnings and the backup entry method before you need it.

Smart Lock Installation across Sierra Madre

Sierra Madre is compact and walkable, and the housing reflects it. In the 91024 and 91025 ZIP codes you will find Craftsman cottages and bungalows near the village core, many with original doors that have been painted, planed and re-hung over a century. Near the wisteria vine, a tenant turnover or a lost key often prompts the call: owners want to stop worrying about copied keys, and a keypad or smart deadbolt lets them change the code instead of the cylinder.

Sierra Madre Canyon is a different job. The lanes are narrow and steep, the cabins are old, and many doors still carry original skeleton-key mortise locks or other non-standard preparations. We are happy to park below and carry tools up when the lane demands it. On those doors we look carefully before promising anything, because a mortise lock may be better retrofitted, rekeyed or paired with a separate keyless option than replaced outright.

Downtown, the small shops around Kersting Court are a natural fit for keypad entry: staff codes can be added or removed without handing out keys, which helps with seasonal hires and turnover. Whether you live a short walk from Mary's Market, near the trailhead at Bailey Canyon Wilderness Park or the Mount Wilson Trail, or just off Sierra Madre Blvd or Baldwin Ave, call (323) 997-8867 and we will come to you.

Smart Lock Installation in Sierra Madre — FAQs

Can you install a smart lock on an old Sierra Madre Craftsman door?
Often yes, but it depends on the door. We check thickness, existing bore holes and condition first. If the door is too delicate or oddly prepared, we will recommend an alternative rather than force a bad fit. Call (323) 997-8867 to describe your door.
I have an original skeleton-key mortise lock in Sierra Madre Canyon. Can it be made smart?
A mortise lock is built differently from a standard deadbolt, so it usually is not a simple swap. Options include carefully retrofitting, rekeying the existing lock, or adding a keyless deadbolt elsewhere on the door. We assess it in person and explain the tradeoffs.
Do you work in the canyon where the lanes are narrow and steep?
Yes. If the van has to park below, we carry the tools up. Mention the address and any access limits when you call so we can plan the visit.
What happens if the batteries die or the Wi-Fi goes down?
Good smart locks have a backup, such as a physical key, a battery terminal for a temporary boost or a keypad that works without internet. We explain your lock's backup method during setup so you are never surprised.
Can you set up a lock I already bought?
Yes, we can install and program locks you supply. We may point out compatibility concerns with your door or home network first. Call (323) 997-8867 with the model and we can talk it through.
Is a keypad lock a good idea for a shop near Kersting Court?
It can be, especially when staff change often, since you can add and remove codes without rekeying. We can talk through the door type, how many people need access and whether you want an app or just a keypad.
Can you help with a smart lock that stopped working?
Yes. We troubleshoot pairing problems, weak batteries, calibration and door alignment issues, which are common causes of lock failure. If the device itself is faulty, we will tell you before replacing anything.
Are you available at night or on weekends?
We are a 24/7 mobile locksmith, so you can call any time. For urgent situations such as a lockout, call (323) 997-8867 directly.
