Aluminum storefront door with mortise lock and pull handle
Open now(323) 997-8867

A commercial door works harder than almost anything else in a building. It opens and closes hundreds of times a day, gets pushed by carts and shoulders, and is expected to lock cleanly every night. When the hardware starts to fail, you notice quickly: a storefront door that will not latch, a panic bar that sticks, a closer that slams or barely moves, or a mortise lock that turns but does not retract the bolt.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades around the hardware found on Valley commercial properties. We repair and replace storefront and aluminum-frame door hardware, mortise locksets, pull handles, push bars, exit devices, closers, and the strikes and hardware that go with them. We are fully mobile, so there is no storefront to visit: we bring the tools and parts to your door in Sylmar.

Sylmar is a large, spread-out community, and its commercial properties vary a lot. There are small shops and offices along Foothill Boulevard, light commercial and service buildings near Roxford Street and Hubbard Street, and institutional and medical sites around Olive View-UCLA Medical Center. Add a long history of seismic movement, and doors and frames here can end up out of square. That makes careful diagnosis as important as the replacement part itself.

How it works in Sylmar

  1. 1

    Call and describe the door

    Call (323) 997-8867 any hour. Tell us what type of door it is (aluminum storefront, hollow metal, or wood), what the hardware is doing or not doing, and whether the door can currently be secured. If it cannot lock, we focus first on getting your business safely closed.

  2. 2

    On-site inspection of door, frame and hardware

    We come to your location and look at the whole assembly, not just the lock. We check the hinges or pivots, the closer, the latch and strike alignment, the frame, and the threshold. Frames that have shifted or racked over the years often turn out to be the real cause of a latch that fails.

  3. 3

    Repair or replace, with options

    If the existing hardware can be adjusted or repaired reliably, we say so. If it is worn out, discontinued, or the wrong grade for the traffic it sees, we explain replacement options for your door type and security needs, so you can decide with clear information.

  4. 4

    Installation and alignment

    We install the new hardware or make the repair, then align the latch, strike, closer and any exit device so the door operates smoothly and locks fully. On aluminum-frame doors we pay close attention to the narrow stile and backset limits that determine which hardware will fit.

  5. 5

    Rekeying and key control if needed

    When hardware changes, it is a good moment to rekey. We can rekey the new or existing locks to your key system, which is useful after a tenant change, an employee departure, or a lost key.

  6. 6

    Final test and walkthrough

    Before we leave, we cycle the door repeatedly, test the lock from both sides, check closing speed and latching, and show you how everything works so you are confident locking up that night.

What affects the price

  • The type of door and frame: aluminum storefront, hollow metal and wood doors each use different hardware, and some narrow-stile aluminum doors need specialty parts.
  • Whether the hardware can be repaired or adjusted versus fully replaced, including whether parts are still available for older mortise or exit devices.
  • The grade and function of the hardware you choose, such as a standard storefront lock, a heavy-duty mortise lockset, or an exit device with different trim.
  • The condition of the door and frame, since racked or shifted frames may need extra alignment work before new hardware will perform properly.
  • The number of doors and whether rekeying or keying to an existing system is included.
  • Timing and access: after-hours or urgent calls differ from scheduled daytime work, and tight or hard-to-reach installations can add labor.

Why Sylmar chooses us

  • Fully mobile, 24/7 service: we come to your Sylmar business at night or on weekends, which matters when a door will not lock and you cannot leave the property unsecured.
  • In business since 1987, with owner David Shar personally involved, so you are dealing with long experience rather than a rotating cast.
  • We diagnose the whole door assembly, including the frame, closer and strike, instead of just swapping a lock and hoping the problem goes away.
  • We tell you plainly when a repair is enough and when replacement makes more sense, rather than pushing the larger job.
  • We understand the realities of older Valley buildings, where settling and past earthquake movement can leave frames out of alignment.
  • We can rekey as part of the visit, so hardware and key control are handled together.

Commercial Door Hardware across Sylmar

Sylmar stretches from the valley floor up into the San Gabriel foothills, and its commercial doors reflect that range. In the 91342 ZIP code you will find storefronts and small offices along Foothill Boulevard, service and light commercial buildings near Hubbard Street and Roxford Street, and the institutional properties around Olive View-UCLA Medical Center in the Olive View and foothills district. Each has different needs, from a busy retail glass door to a clinic office that needs reliable, quiet, easy-to-operate hardware.

The area's seismic history is not just trivia for door work. Sylmar was the epicenter of the 1971 earthquake and felt heavy effects from Northridge in 1994, and decades of settling can leave frames slightly racked. A storefront door that suddenly will not latch, or an older mortise lock whose bolt no longer lines up with the strike, often points to a frame that has moved. We check alignment first so the new hardware is not fighting the door.

We also work for businesses and property managers near El Cariso and Rancho Cascades, including offices, HOA-related facilities and mixed-use sites, as well as properties near the I-5, I-210 and SR-14 interchange where commuters and delivery traffic keep doors busy. Wherever you are in Sylmar, call (323) 997-8867 and we will come to you.

Commercial Door Hardware in Sylmar — FAQs

Do you repair storefront and aluminum-frame doors in Sylmar?
Yes. We repair and replace hardware on aluminum storefront doors, including locks, pull handles, push bars, closers and strikes. Call (323) 997-8867 and tell us about the door so we can bring suitable parts.
Can you come after hours if my business door will not lock?
Yes. We are 24/7 and fully mobile, so we can come to your Sylmar business at night or on weekends. Call (323) 997-8867 and we will focus on getting the door secured.
What is mortise hardware, and can you fix it?
A mortise lockset is a heavy-duty lock body set into a pocket cut in the edge of the door. It is common in older commercial buildings. We can service, repair or replace mortise locks, and we rekey them when needed.
Why does my door not latch even though the lock is new?
Often the issue is alignment rather than the lock. Frames can shift over time, especially in an area with seismic history like Sylmar, so the latch and strike no longer meet. We adjust or realign the strike and frame as part of the repair.
Can you rekey my business at the same time as the hardware work?
Yes. Rekeying during a hardware visit is common, especially after a tenant change or when keys have been lost. We can key the locks to your system so you control who has access.
How much does commercial door hardware repair cost?
It depends on the door type, whether the hardware can be repaired or must be replaced, the grade of hardware, the condition of the frame, and the number of doors. We explain the options on site before work begins.
Do you have a shop I can visit?
No. We are mobile only, with no storefront to visit. We come to your location anywhere in Sylmar, and you can reach us at (323) 997-8867.
Do you work on closers and panic bars as well as locks?
Yes. Door closers, exit devices and panic bars are part of the hardware we repair, adjust and replace, since they all affect how a commercial door closes and secures.
