A commercial door works hard. It opens and closes hundreds of times a day, gets pushed by carts and deliveries, and is expected to lock reliably every night. In Duarte, that applies to the offices, clinics and small shops along Huntington Drive (Route 66), the medical-professional suites near City of Hope, and the retail strips off Mountain Avenue and Buena Vista Street. When the hardware starts to fail, it usually announces itself first: a latch that sticks, a push bar that rattles, a cylinder that needs jiggling, or a door that no longer closes fully.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar. Commercial door hardware is a different trade from residential work. Aluminum storefront doors have narrow stiles that limit which locks fit. Mortise locks are built into the edge of the door and need careful handling. Panic and exit devices have to work correctly for safety as well as security.

We are fully mobile and have no storefront to visit. We come to the door, inspect what is actually wrong, and repair it where possible. When a part is worn out, we replace it with hardware suited to the door, the frame and how the business uses it. Call (323) 997-8867 any hour.

How it works in Duarte

  1. 1

    Describe the door and the problem

    When you call, tell us what kind of door it is (glass storefront, aluminum frame, wood or hollow metal) and what is happening: sticking, not latching, loose, broken key, or a failed lock. Photos help if you can send them. That lets us bring the right parts on the first visit.

  2. 2

    On-site inspection

    We come to your Duarte location and look at the whole door, not only the lock. Misaligned frames, worn hinges, weak closers and loose mounting often cause hardware failures, and replacing a lock will not fix them.

  3. 3

    Repair or replace, explained plainly

    If adjusting, lubricating or swapping a small part will do the job, we say so. If the hardware is worn out or does not suit the door, we explain the replacement options before any work begins.

  4. 4

    Installation and fitting

    We install storefront locks, mortise hardware, push-pull sets, exit devices or closers to suit your door. Aluminum-frame doors have tight clearances, so we fit carefully so the latch, strike and cylinder line up properly.

  5. 5

    Rekey or key control, if needed

    If a former employee, tenant or vendor still has a key, we can rekey the cylinders or set up a key arrangement that fits how many people need access.

  6. 6

    Final test

    We run the door through repeated open, close, lock and unlock cycles, check that it latches and secures, and confirm that any exit hardware releases as it should before we leave.

What affects the price

  • The type of door: aluminum storefront, hollow metal and wood doors each need different hardware and installation methods.
  • Whether the hardware can be repaired or must be fully replaced, and the grade and style of hardware chosen.
  • The number of doors involved and whether they should be keyed alike or on a controlled key system.
  • Hidden problems such as a bent frame, worn hinges or a failing closer that must be addressed along with the lock.
  • Whether the work is an urgent after-hours call or a scheduled visit.
  • Special items like exit devices, mortise cases or specialty cylinders that may need to be sourced.

Why Duarte chooses us

  • Mobile service, so we work on your door at your location and there is no shop trip or storefront to visit.
  • Available 24/7, which matters when a business cannot be left unsecured overnight.
  • Service in the trade since 1987, with owner and lead tech David Shar leading the work.
  • We look at the whole door assembly, so we fix the real cause of a failure instead of replacing parts that were not the problem.
  • Experience with aluminum-frame storefront doors and mortise hardware, where narrow stiles and tight fits make correct parts important.
  • Plain explanations of repair versus replacement, with options discussed before work begins.

Commercial Door Hardware across Duarte

Duarte is a compact foothill city, and its commercial doors reflect that. Along Huntington Drive (Route 66) and Mountain Avenue you find small offices, shops and service businesses, many in older buildings with aluminum storefront frames that have seen decades of daily use. Around the City of Hope medical campus, clinics and professional suites in ZIP 91010 depend on doors that lock securely and release properly at the end of long days.

Businesses sit close to residential areas such as Butler, Cotter and Royal Oaks, so many owners live nearby and want a quick, practical fix rather than a major project. Properties in ZIP 91009 and those near the A Line also see steady foot traffic, which wears out latches, closers and push bars faster than people expect. Our mobile service covers these areas from I-210 (Foothill Fwy) and I-605 (San Gabriel River Fwy) to the quieter streets near Encanto Park and the Duarte Recreational Trail.

Whether it is a sticking storefront latch, a worn mortise lock or an office door that will not stay secured, call (323) 997-8867 and we will come to you.

Commercial Door Hardware in Duarte — FAQs

Do you repair commercial door hardware in Duarte, or only replace it?
Both. If a door can be fixed with an adjustment, lubrication or a small part, we repair it. If the hardware is worn out or unsuited to the door, we explain replacement options. Call (323) 997-8867 to describe the problem.
Can you work on aluminum storefront doors?
Yes. Aluminum-frame doors have narrow stiles and limited space for locks, so hardware must be matched to the frame. We inspect the door first and then fit appropriate hardware.
What is a mortise lock, and can you service one?
A mortise lock sits inside a pocket cut into the edge of the door. It is common in older commercial buildings. We can repair, rebuild, rekey or replace mortise hardware depending on its condition.
Do you offer emergency service for a business that cannot lock up?
We are available 24/7 and fully mobile. If a door will not secure, call (323) 997-8867 at any hour and we will work out the next step with you.
Can you rekey my business after an employee leaves?
Yes. Rekeying cylinders makes old keys stop working without always replacing all the hardware. We can also set up multiple doors on a common key if that suits your operation.
Why does my door lock stick even after I replaced the lock?
Often the cause is door alignment, a worn hinge, a weak closer or a shifting frame, not the lock itself. We check the whole assembly so the actual cause gets fixed.
Do you have a shop in Duarte I can visit?
No. We are fully mobile only, so we come to your business location. There is no storefront to visit.
How is the cost of commercial hardware work determined?
It depends on the door type, whether we repair or replace, the hardware grade, how many doors are involved and whether the call is urgent. We explain the options before starting. Call (323) 997-8867 to discuss your door.
