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 reliably every night. When the hardware starts to fail, you notice quickly: a latch that needs a shove, a closer that slams, a deadbolt that won't throw, or a push bar that sticks. In a Walnut business, any of those can mean an unsecured building or a door customers struggle to use.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades working on the hardware found in commercial buildings. We handle storefront and aluminum-frame doors, which use narrow-stile locks, pivots and thumbturn hardware, and mortise lock bodies, which sit inside the door edge and are common in older professional and institutional buildings. We repair what can be saved and replace what cannot.

We are a mobile service only. There is no storefront to visit, because the work is done at your door. Walnut's commercial and institutional properties, from small offices and retail strips along Valley Blvd and Lemon Ave to buildings near Mt. San Antonio College, are all places we can come to, day or night, with the parts and tools to diagnose the problem on site.

How it works in Walnut

  1. 1

    Call and describe the door

    Phone (323) 997-8867 and tell us what the door is doing: the type of door (glass storefront, aluminum frame or solid with a mortise lock), what has failed, and whether the building is currently secure. This helps us bring the right parts and tell you whether the situation is urgent.

  2. 2

    On-site inspection

    We come to your location and look at the whole door assembly, not just the lock. Misaligned frames, worn pivots, a tired closer or a bent strike plate often cause what looks like a bad lock, and finding the true cause avoids replacing the wrong part.

  3. 3

    Repair or replace recommendation

    We explain what we found in plain language. Some hardware can be adjusted, rekeyed or rebuilt. Other pieces, like a worn mortise body or a cracked aluminum-door lock, are better replaced. You decide, and we explain the tradeoffs before work starts.

  4. 4

    Hardware work and fitting

    We install or repair the hardware, including locksets, push bars, panic devices, closers, strikes and mortise cylinders as needed. Each piece is fitted so the door latches smoothly without forcing, and keyed to your system when required.

  5. 5

    Testing and handover

    We cycle the door repeatedly, test the lock from both sides, check the closer's swing and latch speed, and confirm the door secures properly. You receive working keys and a clear explanation of what was done, so the door is ready for business.

What affects the price

  • The type of door and frame: narrow-stile aluminum storefront hardware, wide-stile doors and mortise doors each use different parts and take different amounts of labor.
  • Repair versus full replacement: adjusting or rebuilding existing hardware is usually less involved than swapping in a new lockset, panic device or mortise body.
  • Hardware grade and finish: commercial-rated hardware varies by durability, finish and function, and matching existing hardware across several doors can affect the parts selected.
  • Number of doors and keying needs: several doors, master keying or keying alike to an existing system adds time compared with a single door.
  • Condition of the frame and door: bent frames, worn pivots or misaligned strikes may need correction before new hardware will work properly.
  • Timing of the call: after-hours or urgent requests, particularly when a door must be secured immediately, can affect how the job is scheduled and quoted.

Why Walnut chooses us

  • Fully mobile, 24/7 service means we come to your door, so a failed lock overnight does not leave your Walnut business unsecured until morning.
  • Business operating since 1987, with owner David Shar personally involved, so the experience behind the work is long-standing and not newly assembled.
  • We work on storefront, aluminum-frame and mortise hardware, which are the door types most commonly found in commercial buildings.
  • We diagnose the whole door assembly, including closers, pivots and strikes, instead of automatically replacing the lock.
  • We explain repair versus replacement honestly and let you choose, with no pressure to buy more than the door needs.
  • There is no storefront or showroom, which keeps the focus on getting to your property and finishing the work there.

Commercial Door Hardware across Walnut

Walnut sits between the San Jose Hills and Puente Hills, and its commercial life follows the main roads: Valley Blvd, Lemon Ave, Grand Ave, Amar Rd, Nogales St and Pierre Rd, with SR-60 and SR-57 close by for access from neighboring cities. Small offices, medical and professional suites, retail strips and service businesses in ZIP codes 91789 and 91788 rely on dependable door hardware, and we serve both.

The north end of the city is anchored by Mt. San Antonio College, where institutional buildings and heavy student foot traffic put steady wear on doors. Commercial properties in the Mt. San Antonio College area and along Grand Ave deal with constant opening and closing, which wears closers, pivots and latches faster than in a quiet office. That kind of use is exactly where proper repair or hardware replacement pays off.

Walnut is also largely a newer suburban city, with neighborhoods like Walnut Heights and the gated Snow Creek community nearby, and businesses and community buildings that serve those residents near parks like Suzanne Park and Creekside Park. Whether you manage a small commercial space near those areas or a building closer to the freeway, call (323) 997-8867 and we will come to you.

Commercial Door Hardware in Walnut — FAQs

What kinds of commercial door hardware do you repair in Walnut?
We repair and replace storefront hardware, aluminum-frame door locks, mortise lock bodies and cylinders, push bars, panic devices, closers and strike plates. If you are unsure what type of door you have, call (323) 997-8867 and we will help identify it.
Are you available after hours if my business door will not lock?
Yes. We are available 24/7 and fully mobile, so we can come to your Walnut business when a door will not secure. Call (323) 997-8867 and describe the situation.
Can you fix an aluminum storefront door that sticks or will not latch?
Often, yes. Sticking or poor latching can come from the lock, a worn pivot, a misaligned strike or a closer that needs adjusting. We inspect the full door assembly to find the real cause before recommending a repair or replacement.
What is a mortise lock and can it be repaired?
A mortise lock has a deep body set into the edge of the door, and it is common in older commercial and institutional doors. Many can be rebuilt or have parts replaced, though a badly worn body may be better swapped out. We explain the options after inspecting it.
Do you have a shop I can visit?
No. Crenshaw Lock Company is mobile only, with no storefront. We bring the tools and parts to your Walnut property, and you can reach us anytime at (323) 997-8867.
Can you match new hardware to my existing doors or keying?
We can often match style and function across multiple doors, and key new hardware alike or to an existing system where the hardware allows. Availability depends on the existing hardware, so we confirm during the on-site inspection.
Do you service doors near Mt. San Antonio College?
Yes. We serve commercial and institutional properties across Walnut, including the Mt. San Antonio College area and Grand Ave. Heavily used doors there often need closer, latch or pivot work, and we can assess it on site.
How is the cost of commercial door hardware work determined?
Cost depends on the door and frame type, whether the hardware is repaired or replaced, the hardware grade, the number of doors and the timing of the call. We explain the scope before starting. For a conversation about your door, call (323) 997-8867.
