Aluminum storefront door with mortise lock and pull handle

A commercial door works harder than almost anything else in a building. It opens and closes hundreds of times a day, takes the weight of deliveries and foot traffic, and is the first thing a would-be intruder tests. When the hardware starts to fail, you notice: a panic bar that sticks, a closer that slams or barely moves, a mortise lock that needs a jiggle, or a storefront thumbturn that no longer catches. Crenshaw Lock Company repairs and replaces that hardware for businesses across Altadena, and we have been doing commercial and residential lock work in the Los Angeles area since 1987.

Our work centers on three common types of entrance. Aluminum-frame storefront doors use narrow stiles and specialized hardware, so parts have to fit the profile rather than just the lock. Mortise locksets are built into a pocket cut in the door edge and are found on older commercial buildings and sturdy offices. We also handle the general run of commercial hardware around them: exit devices, closers, strikes, hinges, pulls, and rekeying or keying systems that go with new locks.

We are a mobile service only. There is no storefront to visit and nothing for you to drive to. A technician arrives with a stocked vehicle, looks at the door in its actual condition, and repairs what can be repaired. When replacement is the sounder choice, we explain why and what the options are. Altadena has a particular situation right now: after the January 2025 Eaton Fire, a great deal of local work involves rebuilt properties, new commercial spaces, and surviving buildings dealing with heat and soot damage, and hardware is a real part of that.

How it works in Altadena

  1. 1

    Call and describe the door

    Phone (323) 997-8867 and tell us what the door is doing: sticking, not latching, locked out, or damaged. Mention the frame type if you know it (aluminum storefront, wood, hollow metal) and whether the lock is a mortise body or a surface device. That helps us bring the right parts.

  2. 2

    On-site inspection

    We examine the door, frame, hardware and how it closes. Many hardware complaints are alignment problems or worn closers rather than a bad lock. We check strike position, hinge wear, and any heat or soot residue that may be seizing moving parts.

  3. 3

    Repair or replace, with a clear recommendation

    If a part can be cleaned, adjusted, or rebuilt, we say so. If a mortise body, exit device, or storefront lock is past saving, we explain the replacement choices and how each would fit your door and frame before any work starts.

  4. 4

    Installation and fitting

    We install the hardware, set the latch and strike so the door closes cleanly, and confirm that the lock throws fully. On aluminum-frame doors, we pay close attention to the narrow stile so the new hardware seats properly.

  5. 5

    Keying and key control

    When new cylinders go in, we can key them to your existing keys or set up a new system, including a simple master-key arrangement for multiple doors, which suits rebuilds and multi-tenant spaces.

  6. 6

    Final test and walkthrough

    Before we leave, we operate the door with you: key, thumbturn, push bar, closer speed, and latching. You see it working and know how to use and maintain it.

What affects the price

  • The type of door and frame, since aluminum storefront, hollow metal, and wood doors call for different hardware and installation methods.
  • Whether the existing hardware can be repaired or needs full replacement, and the grade and style of the replacement parts you choose.
  • The number of doors and cylinders involved, including whether you want keyed-alike or master-key setups.
  • Complexity of the work, such as mortise body replacement, exit device installation, or modification to fit an existing door prep.
  • Condition of the door and frame, including misalignment, heat or soot damage, or prior failed repairs that must be corrected first.
  • Timing of the visit, as after-hours and emergency service differs from a scheduled daytime appointment.

Why Altadena chooses us

  • Fully mobile and available 24/7, so a failed door lock does not have to leave your business unsecured overnight.
  • In business since 1987, led by owner and lead technician David Shar, with long experience across commercial and residential hardware.
  • Familiarity with aluminum-frame storefront and mortise hardware, not just residential deadbolts.
  • Honest repair-first approach: if adjustment or cleaning solves it, we will not push a replacement.
  • Keying and master-key setups handled in the same visit as the hardware work, which suits rebuild projects and shared spaces.
  • No storefront overhead to navigate: we come to you with the tools and parts on board.

Commercial Door Hardware across Altadena

Altadena is a foothill community with a mix of small commercial strips, civic spaces, and neighborhood businesses along corridors such as Lake Ave, Lincoln Ave, Fair Oaks Ave, and Altadena Dr. Businesses in ZIP codes 91001 and 91003 range from older buildings with mortise locks to newer storefronts with aluminum-frame glass doors. We work on these, and on the doors that serve churches, offices, and shops around areas like Farnsworth Park, Charles White Park, and the Woodbury Rd side of town.

The January 2025 Eaton Fire changed what local lock work looks like. Many properties are now in rebuild: new construction needs fresh hardware, keying, and a master-key system, and active jobsites need to be secured with contractor lockboxes. On surviving buildings, we also see locks and cylinders that seized after heat, smoke, and months of ash exposure. In Janes Village, with its older Craftsman and mid-century buildings, soot-fouled hardware often needs careful freeing and rekeying rather than blanket replacement.

Whether your business sits near Christmas Tree Lane on Santa Rosa Avenue, close to the Altadena Country Club, in The Meadows, or by the Cobb Estate and Sam Merrill Trailhead, we come to you. Call (323) 997-8867 and we will talk through the door, the hardware, and what makes sense for your building.

Commercial Door Hardware in Altadena — FAQs

What kinds of commercial door hardware do you repair in Altadena?
We work on storefront and aluminum-frame door hardware, mortise locksets, exit devices, closers, strikes, hinges, and related parts. Call (323) 997-8867 to describe your door and we will tell you what we can do.
Do you work on aluminum storefront doors?
Yes. Aluminum-frame doors have narrow stiles and specific hardware profiles, so we match the lock and parts to the frame rather than forcing a standard fit.
Can you replace a mortise lock, or only repair it?
Both. We rebuild or adjust a mortise lock when that is sound, and replace the mortise body when it is worn or damaged. We will explain our recommendation before starting.
Are you available after hours if my business door will not lock?
Yes, we are available 24/7 and fully mobile. If your door will not secure, call (323) 997-8867 and we will help get it working again.
Can you set up a master-key system for a rebuilt property?
Yes. We supply and key new locks and can set up a simple master-key system, which is useful on Eaton Fire rebuilds and multi-door or multi-tenant spaces.
My locks seized after the fire. Can they be saved?
Often they can be freed and rekeyed, depending on how much heat and soot damage occurred. We inspect first and replace only what cannot be restored.
Do you secure construction jobsites?
We set contractor lockboxes and can provide keyed hardware to help control access to a jobsite during construction.
Do I need to come to a shop?
No. Crenshaw Lock Company is mobile only, with no storefront to visit. We come to your Altadena location, and you can reach us at (323) 997-8867.
