A business in Monrovia rarely has just one kind of lock problem. A restaurant on Myrtle Avenue may have an aging storefront deadbolt and a back door that gets heavy use every night. An office near Huntington Drive may need keys tracked after an employee leaves. A warehouse or shop near Foothill Boulevard may have a mix of padlocks, roll-up gates and personnel doors installed in different decades. Our commercial locksmith work is built around those real situations.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile. There is no storefront to visit; we bring tools, key-cutting capability and common hardware to your location, whatever the hour. That matters for a business, because a door that will not lock at closing or will not open at opening is a problem that cannot wait.

This page explains how our commercial work usually goes in Monrovia, what affects the cost, and what to think about before you call. If your situation is urgent, call (323) 997-8867 and we will talk it through with you directly.

How it works in Monrovia

  1. 1

    Tell us about the building and the problem

    When you call, we ask what kind of business it is, which door is involved, whether it is a lockout, a broken key, a failed lock or a rekey, and whether the property is occupied. For a storefront in Old Town we also ask about the door type, since glass storefront doors, wood doors and metal back doors all call for different approaches.

  2. 2

    Confirm access and authorization

    Before opening or rekeying anything, we need to be reasonably sure the person asking is entitled to give that instruction, such as the owner, a manager or the property manager. This protects you and your landlord. We may ask for reasonable verification on site.

  3. 3

    Assess the hardware on site

    We look at the actual lock, the door and the frame. Commercial doors in Monrovia range from older mortise cylinders to newer commercial deadbolts, panic hardware and electronic locks. We explain what can be repaired, what can be rekeyed and what should be replaced, and why.

  4. 4

    Do the work with as little damage as possible

    For lockouts, we aim to open the door without damaging it. For rekeying, we change the lock's internal pinning so old keys stop working, which is often more economical than replacing hardware. If replacement is the better choice, we say so plainly.

  5. 5

    Test every lock and organize your keys

    After the work, we test each lock, cut and label keys as needed, and confirm the door secures properly. If you have several doors, we can discuss keying them alike or setting up a master key arrangement so staff carry fewer keys.

  6. 6

    Talk through follow-up security

    If we notice worn strike plates, loose frames or a back door that is easy to defeat, we mention it. You decide what, if anything, to do. We do not push upgrades you do not need.

What affects the price

  • Type of service: a lockout, rekey, repair, new installation and master key setup involve very different amounts of labor and parts.
  • Hardware type and condition: standard commercial cylinders, mortise locks, panic bars, high-security cylinders and electronic access hardware vary widely in cost and availability.
  • Number of doors and keys: rekeying one storefront door is a smaller job than keying an entire multi-door office or warehouse, and key quantity affects the total.
  • Time of day: after-hours, overnight, weekend and holiday calls involve different scheduling demands than a planned daytime visit.
  • Condition of the door and frame: warped, damaged or poorly aligned doors may need adjustments before a lock will work reliably.
  • Location and access: a call to a business in Old Town differs from one at a larger industrial site, particularly where gates, multiple buildings or restricted areas are involved.

Why Monrovia chooses us

  • Fully mobile 24/7 service means we come to your business instead of asking you to leave it unsecured and travel to a shop.
  • Operating since 1987 gives us long experience with older and mixed-age commercial hardware like that found along Myrtle Avenue.
  • You deal directly with a small, owner-led operation under David Shar rather than a call center that dispatches an unknown contractor.
  • We try to repair or rekey before recommending replacement, which can keep costs reasonable and preserve existing doors.
  • We explain what we find and what your options are before starting work, so you stay in control of decisions.
  • We can handle a range of commercial needs in one visit, including lockouts, rekeying, key duplication and lock repair.

Commercial Locksmith across Monrovia

Monrovia's commercial landscape is varied. Old Town Monrovia, centered on Myrtle Avenue near Library Park and the historic Aztec Hotel, is a walkable strip of small shops and restaurants, many in older buildings where the locks were added or replaced over several decades. Storefront lockouts, a lost key after a staff change, or a back door that no longer latches well are common reasons businesses here need help. Many of these buildings sit in ZIP code 91016, and we regularly consider the foot traffic, tight rear access and evening hours that come with Old Town operations.

Further out, businesses along Huntington Drive, Foothill Boulevard and Mountain Avenue run from small offices to service shops and storage space, and drivers reach them easily from the I-210 (Foothill Freeway). Mayflower Village has its own neighborhood-scale businesses, and the area around the Metro A Line station brings steady daily activity that shapes how owners think about closing procedures and key control. ZIP code 91017 and surrounding areas include mixed commercial and residential property where we may work on both in one visit.

Monrovia's older character shows up in its buildings too. Many structures in and around Old Town carry original or very old hardware, including mortise locks that should be repaired or rekeyed carefully rather than ripped out. North Monrovia, toward the foothills and Monrovia Canyon Park, includes home offices and larger lots with gates. Whether it is a commercial storefront or a business that operates from a property in those hills, we come to you at any hour.

Commercial Locksmith in Monrovia — FAQs

Do you offer 24/7 commercial locksmith service in Monrovia?
Yes. Crenshaw Lock Company is available 24 hours a day, seven days a week, and we are fully mobile. Call (323) 997-8867 any time, including nights, weekends and holidays.
Can you open a locked storefront on Myrtle Avenue without damaging the door?
In most cases, yes. We aim to open doors without damage, though the method depends on the lock and door type. We will tell you what we see before we begin, and if damage is unavoidable we explain why.
Is rekeying better than replacing the locks for my business?
Often rekeying is the more economical choice if the hardware is still in good shape. It makes old keys stop working without replacing the lock body. If the lock is worn or damaged, replacement may make more sense.
Can you rekey the old mortise locks in an Old Town building?
Many mortise locks can be rekeyed or repaired, which helps preserve older doors and period hardware. We inspect the lock first to confirm it can be serviced. Call (323) 997-8867 to describe what you have.
Can you set up a master key system for my office or warehouse?
Yes. A master key arrangement lets different people open different doors while a few keys open everything. We discuss how many doors, how many users and what level of access control you need before planning it.
Do you have a shop I can visit in Monrovia?
No. We are a mobile-only service with no storefront. We travel to your business, which means you do not have to leave your property unsecured.
Why does the price of commercial lock work vary so much?
Cost depends on the type of service, the hardware, the number of doors and keys, the time of day and the condition of the door. We discuss these factors with you before work begins. You can reach us at (323) 997-8867.
What should I do after an employee leaves with keys?
Rekeying the affected locks is usually the simplest fix, since it makes the missing keys useless. We can do this on site for one door or several, and discuss ways to track keys going forward.
