A commercial door is one of the hardest-working pieces of hardware in any building. In Chatsworth, that might be an aluminum-frame storefront door on Devonshire Street, a mortise lockset on an older office suite, or a steel door at the back of a warehouse off Lassen. When the hardware drags, sticks, rattles or fails to latch, it is more than an annoyance. A door that will not lock leaves a business exposed overnight, and one that will not open slows everyone down.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen most of the ways commercial hardware wears out. We are mobile only. There is no storefront to visit, so we bring our tools and a working knowledge of commercial hardware to your door, at any hour, any day.

This page covers what we do for commercial door hardware in Chatsworth: diagnosing worn or damaged hardware, repairing what can be saved, and replacing what cannot. We try to be honest about which is which, because a good repair often costs less than a full swap and a bad repair costs more in the long run.

How it works in Chatsworth

  1. 1

    Tell us about the door and the problem

    Call (323) 997-8867 and describe what you have: a glass storefront door with an aluminum stile, a mortise lock in a wood or hollow-metal door, a panic device on a rear exit. Tell us what is going wrong, whether it is a sticking latch, a loose handle, a lock that will not turn, or a door that will not close fully. Photos of the hardware help if you can send them.

  2. 2

    On-site inspection

    We look at the whole door, not only the lock. Commercial doors often fail because of hinges that have sagged, closers that are out of adjustment, or strike plates that no longer line up. Finding the real cause keeps you from paying to replace a part that was never the problem.

  3. 3

    Repair or replace, explained plainly

    If the hardware can be cleaned, adjusted, re-pinned or rebuilt, we will say so. If a mortise body is worn out, a storefront latch is bent, or parts are no longer available, we explain why replacement makes sense and what options fit your door and frame.

  4. 4

    Installation and fitting

    We install hardware to suit the door type, whether that means aluminum-frame storefront sets, mortise cases and cylinders, or other commercial trim. We check alignment, latch engagement, and how the door swings and closes before calling it done.

  5. 5

    Keying and testing

    We can key new cylinders to match existing keys or set them up as part of a larger key plan, for example when a tenant takes over a space. Before we leave, we operate the door repeatedly from both sides and confirm that every key works.

  6. 6

    Leave you with a secure door

    If the door cannot be fully repaired in one visit, we make it secure for the night and tell you what is still needed. You should never be left with a building that will not lock.

What affects the price

  • The type of hardware involved: a basic storefront latch, a mortise lockset and a panic exit device are very different jobs and parts.
  • Whether the existing hardware can be repaired or must be replaced, and whether matching parts are still available for older doors.
  • The door and frame material and condition, since aluminum storefronts, hollow metal and wood each need different fitting work.
  • How many doors or openings are included, and whether they are being keyed alike or to a master system.
  • Whether the work is scheduled in advance or is an urgent after-hours call that needs a technician right away.
  • Any related repairs uncovered during inspection, such as sagging hinges, misaligned strikes or worn closers.

Why Chatsworth chooses us

  • Fully mobile and available 24/7, so a failed door lock at night or on a weekend does not wait for business hours.
  • In business since 1987, with owner and lead tech David Shar bringing long experience with commercial hardware.
  • We diagnose the whole door assembly, not just the lock, which helps avoid repeat visits for the same problem.
  • We tell you honestly when repair is enough and when replacement is the better investment.
  • We handle keying along with hardware, including rekeying to a single key after a lease change.
  • We stay focused on locks and door hardware instead of treating them as a sideline.

Commercial Door Hardware across Chatsworth

Chatsworth sits in the northwest corner of the San Fernando Valley, backed by the Santa Susana Mountains, and its commercial buildings reflect that mix. The industrial and business district around Canoga Avenue, Prairie Street and Lassen Street holds warehouses, light manufacturing and self-storage, where steel doors, roll-up doors and high-security commercial deadbolts take daily abuse. A typical call here might be a tenant who has taken a new lease and needs deadbolts and padlocks on several doors rekeyed so one key handles all of them. Businesses in ZIP code 91311 along Devonshire Street, Topanga Canyon Boulevard and Nordhoff Street also rely on storefront and aluminum-frame doors that see constant foot traffic.

Heat, dust and wind are part of the picture too. Santa Ana conditions and fine grit can work into lock cylinders and latches, leaving them stiff or seized, a problem we also see on exterior deadbolts of hillside homes near Stoney Point Park. Doors that face the sun or sit in dusty yards often need cleaning, re-pinning or new hardware sooner than those indoors. Older commercial buildings may also still carry mortise locksets that have been in service for decades.

We serve businesses throughout Chatsworth, including ZIP code 91313 and the semi-rural parts of town near Santa Susana Pass Road, where equestrian and ranch properties may have shop doors, barn and tack-room hardware and gates alongside business buildings. Whether you are near the Chatsworth Transportation Center, off the Ronald Reagan Freeway, or out toward the Indian Hills area, we come to you. Call (323) 997-8867 any time.

Commercial Door Hardware in Chatsworth — FAQs

What kinds of commercial door hardware do you repair in Chatsworth?
We work on storefront and aluminum-frame door hardware, mortise locksets, and related commercial trim. If you are not sure what type of door you have, call (323) 997-8867 and describe it. We can usually tell from a description or photo.
Do you offer 24/7 service for commercial doors?
Yes. We are a fully mobile locksmith available 24/7. If a storefront door will not lock or a warehouse door will not open, call (323) 997-8867 at any hour.
Can you repair my hardware, or will I need to replace it?
It depends on the condition. Many sticking or loose sets can be cleaned, adjusted or rebuilt. If parts are worn through, bent, or no longer made, we will explain why replacement is the better choice.
Do you have a shop I can visit?
No. We are mobile only and have no storefront. Our technician comes to your Chatsworth location with tools and common parts.
Can you rekey several doors to one key after a lease change?
Yes. We regularly rekey commercial deadbolts and padlocks so a tenant can run the space on a single key or a simple master plan. Call (323) 997-8867 to talk through how many doors are involved.
Why does dust and heat damage commercial locks here?
Chatsworth sees hot weather, dry air and Santa Ana wind that carries fine grit. That grit can build up inside cylinders and latches, and heat can make worn parts bind. Cleaning and re-pinning can help, but badly worn hardware may need replacement.
How is the cost of commercial hardware work determined?
Cost depends on the hardware type, whether it can be repaired, the door and frame condition, how many openings are involved, and when the work is needed. We explain the options before we start.
Do you work on doors besides the main entrance?
Yes. Back doors, side exits, office suite doors and warehouse personnel doors all use commercial hardware we can service. Call (323) 997-8867 to describe your door and we will advise on the next step.
