A commercial door works harder than almost anything else in a building. It opens hundreds of times a day, it is leaned on, slammed, propped, and kicked, and when its hardware fails the whole business feels it. A storefront that will not latch cannot be left overnight. A mortise lock that sticks can trap staff or keep customers out. In Northridge, where retail, medical, student-oriented and small professional spaces sit side by side, we see every version of that problem.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on fieldwork, not a counter. We are fully mobile. There is no storefront to visit; we bring the tools, common parts, and experience to your door, whether it is an aluminum-frame glass door in a strip center or a heavy mortise lockset in an older professional building.

Commercial door hardware covers more than the lock itself. It includes panic and exit devices, door closers, hinges and pivots, push-pull sets, strike plates, thresholds, storefront deadlatches, mortise cylinders and the keying that ties them together. We repair what can be repaired sensibly, replace what cannot, and tell you plainly which is which, so you are not paying for a new device when an adjustment would do.

How it works in Northridge

  1. 1

    Call and describe the door

    Phone us at (323) 997-8867 any hour. Tell us the door type (aluminum storefront, wood, hollow metal, glass), the hardware involved, and what is going wrong. That lets us bring the right parts the first time.

  2. 2

    On-site inspection

    We examine the lock, latch, closer, hinges, and frame together. Commercial doors often fail because of alignment, wear, or a closer fighting the latch rather than one broken part, so we look at the whole opening.

  3. 3

    Clear recommendation

    We explain whether repair, adjustment, or replacement makes sense and what the options are, including grade of hardware and keying choices, before any work begins.

  4. 4

    Repair or replacement

    We service or install storefront deadlatches, mortise locks, exit devices, closers, and cylinders, fitting to the existing preparation where possible to avoid unnecessary frame or glass work.

  5. 5

    Keying and key control

    If needed we rekey or master key so staff, managers, and maintenance have the access they should and nobody else does. We can key multiple doors alike for convenience.

  6. 6

    Test and secure the opening

    We cycle the door repeatedly, check latching, closing speed, and egress, and confirm the door secures properly before we leave, so you can lock up with confidence.

What affects the price

  • The type of door and frame, since narrow-stile aluminum storefront, hollow metal, and wood doors each need different hardware and labor.
  • Whether the hardware can be repaired or adjusted, or the device has to be replaced entirely.
  • The grade and brand of the hardware you choose, from standard-duty to heavy-duty commercial and code-rated exit devices.
  • How many doors are involved and whether they need rekeying, keyed-alike, or master-key systems.
  • Special parts needs, such as a discontinued mortise lock body, a custom strike, or an unusual cylinder, that must be sourced.
  • The time of the call, since after-hours and emergency service involves different scheduling than a planned daytime visit.

Why Northridge chooses us

  • Fully mobile, 24/7 service means a failed lock does not have to wait until morning or until a shop opens.
  • Serving the Los Angeles area since 1987 gives us experience with older mortise hardware that newer technicians rarely see.
  • We look at the entire opening, including closer, hinges, and frame alignment, rather than swapping a lock that was never the true problem.
  • We tell you honestly when a repair is enough, so you do not pay for replacement you do not need.
  • We handle keying and key control as part of the job, which matters for multi-door businesses and property managers.
  • There is no storefront or showroom; the work and the conversation happen at your door, with the owner's standards behind it.

Commercial Door Hardware across Northridge

Northridge is a mix of commercial environments, and the hardware needs differ among them. Around the CSUN and university district, small offices, food spots, and service businesses serve a constant flow of students and staff, so doors cycle heavily and keys tend to multiply. Along the Devonshire Street corridor and in the Devonshire residential area, older storefronts and professional suites often carry decades-old mortise locks and tired closers that are well worth servicing before they fail.

Northridge Village and the commercial strips along Reseda Blvd, Nordhoff St, and Tampa Ave feature aluminum-frame storefront doors, where deadlatches, pivots, and thumbturn hardware wear quickly. Near the Northridge Fashion Center and Northridge Hospital Medical Center, businesses and offices need doors that latch reliably and meet egress expectations. The 1994 earthquake left a lasting concern about frame settling in this area, and a door that has shifted out of square will bind a latch, so we check alignment, not just the lock.

We serve business owners and property managers in ZIP codes 91324, 91325, 91327, 91328, and 91330, including 91330 near the university and 91324 and 91325 along the Reseda and Devonshire corridors. Sherwood Forest has its own small commercial and equestrian-related needs, and we work with them too. Wherever your door is, call (323) 997-8867 and we will come to you.

Commercial Door Hardware in Northridge — FAQs

Do you repair storefront aluminum-frame door hardware in Northridge?
Yes. We service deadlatches, pivots, thumbturns, cylinders, and push-pull hardware on aluminum storefront doors. Call (323) 997-8867 and tell us what the door is doing.
Can you help if my business door will not lock at night?
Yes. We are 24/7 and fully mobile, so we can come secure the opening, whether that means repairing the latch, adjusting the door, or replacing the lock.
Do you work on old mortise locks?
We do. Many Northridge buildings on Devonshire and Reseda have older mortise hardware. We repair it when sensible and replace the lock body or cylinder when it is worn out.
Could earthquake settling affect my commercial door?
It can. Frames that have shifted over the years can cause binding, misaligned strikes, and latches that drag. We check alignment and adjust or correct it as part of the repair.
Can you rekey multiple doors at my business?
Yes. We can rekey several doors, key them alike, or set up a master key system so the right people have the right access. Call (323) 997-8867 to discuss your layout.
Do you install panic and exit devices?
Yes, we repair and install exit devices and can advise on suitable hardware for your door. Egress requirements matter, so we test operation before we leave.
How is the price determined?
Price depends on the door and frame type, repair versus replacement, hardware grade, number of doors, parts availability, and timing. We explain the options before starting work.
Is there a shop I can visit?
No. We are mobile only and come to your location anywhere in Northridge, including the CSUN area and Northridge Village.
