A smart lock can be a real convenience: no hunting for keys, codes you can give to a dog walker or a relative, and a clear record of who came and went. In Monrovia, though, the door matters as much as the lock. Many homes here are 1900s to 1930s Craftsman bungalows and Victorians, and the doors often carry original mortise or rim hardware that was never designed with an electronic deadbolt in mind. Putting a smart lock on one of those doors takes some thought.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has seen how a good installation and a rushed one differ. We are a mobile-only service with no storefront, so everything starts with a conversation about your door, your habits and what you want the lock to do. Then we come to you and handle the installation, setup and testing on site.

This page is for Monrovia homeowners, landlords and shop owners who want keyless entry done properly. That might be a new keypad deadbolt on a hillside front door, a smart lock on a rental, or an upgrade to a back door off a Myrtle Avenue storefront. We will also help if a smart lock you already own is misbehaving, whether that means pairing trouble, a code that will not take or a bolt that drags.

How it works in Monrovia

  1. 1

    Talk through the door and the goal

    Call (323) 997-8867 and tell us about the door: its age, material, whether it has a mortise lock or a standard bored hole, and what you want from a smart lock. Codes for family, app control, guest access and a physical key backup all affect which lock makes sense.

  2. 2

    Check fit and condition on site

    We look at the door prep, the thickness, the backset, the strike and how the door sits in its frame. Older Monrovia doors often have settled or swollen, and a smart lock that has to fight a sticking bolt will drain batteries and fail early. If the door needs adjustment first, we tell you plainly.

  3. 3

    Choose hardware that suits the door

    We help match a keypad, touchscreen or app-enabled lock to your door and your phone setup. If you have vintage hardware worth keeping, we talk about options such as adding keyless entry elsewhere on the door or on a secondary entrance instead of drilling into period work.

  4. 4

    Install and align

    We mount the lock, set the bolt and strike so it throws smoothly, and make sure the door closes and latches without needing a push. A smart lock only works well when the mechanical side is right.

  5. 5

    Set up codes, app and backup access

    We program user codes, connect the lock to your phone or home system if you want that, and make sure you know how the key override and battery warnings work. We walk you through changing codes yourself.

  6. 6

    Test and hand off

    Before we leave, we cycle the lock from inside and outside, test each code and confirm everything behaves the way you expect. If anything is not right, we fix it then rather than leaving you to figure it out.

What affects the price

  • The type of lock chosen: a basic keypad deadbolt differs from a connected lock with app control and integrations.
  • The condition and prep of the door, since an older door may need boring adjustments, a new strike or some alignment work before a smart lock will work reliably.
  • Whether the door has mortise hardware, which calls for different solutions than a standard deadbolt.
  • The number of doors, such as a front door plus a side-yard or driveway gate lock on a larger hillside lot.
  • How much setup you want: simple code programming versus pairing with a phone, hub or existing smart-home system.
  • Whether the job is scheduled or after hours, since we are available 24/7 and the time of the call can be a factor.

Why Monrovia chooses us

  • Fully mobile: we come to your Monrovia door with tools and hardware, and there is no storefront to drive to.
  • Experience with older doors: since 1987 we have worked on mortise, rim and early deadbolt hardware, which helps on Old Town Craftsman homes.
  • Honest about when not to go electronic: if a vintage lock is better rekeyed than replaced, we say so.
  • We fix the mechanical side first, because a binding bolt or poor strike alignment is the most common reason smart locks fail.
  • We stay for the walkthrough, showing you how codes, batteries and the key backup work before we leave.
  • Smart lock troubleshooting is included in what we do, so we can help with locks installed by someone else.

Smart Lock Installation across Monrovia

Monrovia has a character all its own, and it shapes how smart lock work goes. In Old Town Monrovia, around Myrtle Avenue and Library Park, many homes are Craftsman bungalows and Victorians with original doors and period hardware. Owners here usually want modern convenience without ruining the look or damaging a vintage door, so we focus on careful fitting and, where it makes sense, keyless entry on a secondary door rather than the showpiece entry. Homes in the 91016 area often fall into this group.

North of Foothill Boulevard, in North Monrovia and the foothills toward Monrovia Canyon Park, the housing shifts to hillside custom and mid-century homes. Larger lots can mean a long driveway and a side-yard gate in addition to the front door, and keypad entry is handy when several people come and go or when a gardener or contractor needs access. Many of these properties fall in 91017, and we can look at the gate and the main door in one visit.

Mayflower Village and the Myrtle Avenue corridor add another mix: small homes, small shops and restaurants with locks of mixed ages. For a shop or restaurant near the Aztec Hotel or the Metro A Line station, a keypad on a back or staff door can simplify employee access, though we will talk through fire-code and business needs before recommending anything. Whether you are off I-210, Huntington Drive or Mountain Avenue, call (323) 997-8867 any hour and we will come to you.

Smart Lock Installation in Monrovia — FAQs

Can a smart lock go on an old Craftsman door in Old Town Monrovia?
Often yes, but it depends on the door. Many 1900s to 1930s doors have mortise or rim hardware, and some are thin or already heavily drilled. We inspect the door first and may suggest an option that protects the original work. Call (323) 997-8867 to describe your door.
Do you install smart locks at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile, so we can schedule installation whenever it suits you. For anything urgent, call (323) 997-8867.
Do I need Wi-Fi for a smart lock?
Not always. Many keypad locks work with codes alone and no network. App control, remote access and activity logs usually need Wi-Fi or a hub. We help you decide which features you actually need.
Will I still have a key?
Most smart locks include a physical key override, and we can keep or add one. We also explain how battery warnings work so you are not caught off guard by a dead lock.
Can you install a keypad lock on a side gate or driveway gate?
Often we can, depending on the gate and latch type. On larger hillside lots above Foothill Boulevard, gate locks are a common request alongside the front door. We look at the gate during the visit.
My smart lock is not working. Can you fix it?
We troubleshoot smart, keyless and keypad locks, including ones installed by others. Common causes include weak batteries, pairing issues and a door that binds. Call (323) 997-8867 and tell us what it is doing.
Can you set up a smart lock for my Myrtle Avenue shop?
We can discuss keypad entry for back or staff doors and commercial rekeying for storefronts. We will also talk through how the door is used so the lock fits your business needs.
Is it better to rekey or switch to a smart lock after buying a home?
Either can work. Rekeying is a simple way to cancel old keys, and a smart lock can add code access on top of that. We can talk through which fits your door and budget.
