A new lock is rarely just a lock. In Monrovia it might be a deadbolt for a freshly framed door, hardware for a converted back room, a latch for a side-yard gate, or a full set of locks for a shop taking over a space on Myrtle Avenue. Each one depends on the door, the frame, and who needs a key.

Monrovia's housing makes this more interesting than a simple swap. The city has a deep stock of 1900s to 1930s Craftsman bungalows and Victorians, especially in and around Old Town, where doors are often solid wood and a little out of square after decades. Hillside custom and mid-century homes climb toward the canyon above Foothill Boulevard, with long driveways and larger lots that bring gates and outbuildings into the picture.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit. We bring the tools to your door, look at what is actually there, and install hardware that fits it properly instead of forcing a generic kit into the wrong door.

How it works in Monrovia

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what you are securing: a new entry door, an interior room, a gate, or a commercial door. Details such as door material, thickness, and whether it is already drilled help us arrive prepared.

  2. 2

    On-site assessment

    We examine the door and frame in person. Solid wood in an older bungalow, a hollow-core door, a metal storefront door, and a wooden gate all need different approaches, and we check whether the frame can hold up to a proper strike and screws.

  3. 3

    Choose hardware that suits the door

    We explain realistic options for the use: deadbolts, knob or lever sets, keyed-alike sets, smart-lock-ready hardware, or gate locks built for weather. If you want a period look on a Craftsman door, we talk through what blends in.

  4. 4

    Careful drilling and fitting

    Where no lock existed, we drill the door and cut the latch and strike areas with attention to alignment and edge distance. On vintage doors we work to protect the wood and avoid unnecessary damage.

  5. 5

    Reinforce and test

    We set the strike properly, add longer screws or reinforcement where the frame calls for it, and operate the lock repeatedly to confirm smooth throw and a clean latch. Misaligned installs are what fail first, so we do not skip this.

  6. 6

    Keys and handoff

    We hand over your keys, explain how the hardware works, and can key multiple locks alike so one key covers the front door, side gate, and garage entry if you want that convenience.

What affects the price

  • Number of locks and doors involved, since a single deadbolt differs from a whole property being outfitted.
  • Whether the door is already bored or must be drilled from scratch, which adds labor and precision work.
  • Door material and condition, such as solid wood, hollow-core, metal, or an older door needing extra care.
  • Hardware grade and type, from standard deadbolts to higher-security or smart-ready options.
  • Frame or strike reinforcement needed to make the new lock actually hold up.
  • Time of service, as after-hours and emergency visits are handled differently than scheduled work.

Why Monrovia chooses us

  • Fully mobile service: we come to you across Monrovia, with no storefront and no need to bring your door anywhere.
  • Operating since 1987, with David Shar's hands-on experience guiding how we approach older doors.
  • Respect for vintage hardware and wood: on Craftsman and Victorian doors we aim to install without ruining character.
  • Available 24/7, so a door that has to be secured tonight can be handled tonight.
  • Residential and commercial experience, from bungalow doors to storefront and gate hardware.
  • Honest recommendations: if a frame needs reinforcement or a cheaper lock will not suit the door, we tell you plainly.

Lock Installation across Monrovia

In Old Town Monrovia, the 1900s to 1930s Craftsman bungalows and Victorians around Library Park and the streets off Myrtle Avenue often have doors that were never meant for modern deadbolts. Adding a lock to a converted porch door or a new back entrance in ZIP 91016 usually means working around thick old wood and original trim. We plan the drilling carefully so the door still looks right.

North Monrovia in the foothills, including homes toward Monrovia Canyon Park above Foothill Boulevard in 91016 and 91017, is a different job. Hillside custom and mid-century homes on larger lots often need locks for long-driveway gates, side-yard gates, workshops, and guest houses, and those locks face sun and weather. We select hardware suited to exposure and keep keying consistent where you want one key for several doors.

Myrtle Avenue's Old Town strip has small shops and restaurants with mixed-age doors, and Mayflower Village has its own mix of residences. Whether you are near the Aztec Hotel, close to the Metro A Line station, or just off I-210, Huntington Drive, or Mountain Avenue, we drive to you. Call (323) 997-8867 any hour.

Lock Installation in Monrovia — FAQs

Can you install a lock on a door that has never had one?
Yes. We drill and fit the door from scratch, cut the latch and strike areas, and reinforce the frame if needed. Call (323) 997-8867 and describe the door so we can prepare.
Will a new deadbolt damage my Craftsman bungalow's original door?
We work carefully to limit damage. Solid old doors can take a deadbolt when drilled correctly, and we discuss placement and hardware style first so the result looks appropriate for an Old Town home.
Do you install locks on gates and outbuildings?
Yes. Many hillside lots above Foothill Boulevard have driveway gates, side-yard gates, and sheds. We use hardware suited to outdoor exposure and can key them to match your house.
Can you key several new locks alike?
Yes. We can set up multiple locks on one key, so the front door, back door, and gate all work together. Ask when you call (323) 997-8867.
Do you do commercial lock installation on Myrtle Avenue?
We do. Shops and restaurants in Old Town often have mixed-age doors, and we install or upgrade hardware to fit the door and how the business uses it.
Are you available outside normal hours?
Yes, we are 24/7 and fully mobile. If a new door needs to be secured tonight, we can come out. Please call for availability.
How is the price of a lock installation determined?
It depends on how many locks, whether the door is already drilled, door material, hardware grade, and any frame reinforcement. We explain the factors for your door before work begins.
Can you install smart or keyless locks?
We can install compatible hardware and discuss whether it suits your door. We will also be upfront about whether a traditional deadbolt would be the better choice for your situation.
