A commercial door works harder than almost any other part of a building. It swings open and shut hundreds of times a day, gets pushed by hands full of boxes, and is expected to lock reliably every night. When the hardware starts to fail, the signs are usually small at first: a latch that needs a shoulder bump, a closer that slams, a panic bar that sticks, or a cylinder that turns stiffly. In San Dimas, those problems show up in everything from small retail shops to civic buildings and professional offices.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around mobile service. We do not have a storefront to visit. We bring the tools and a working knowledge of commercial hardware to your door, whether that is an aluminum-frame storefront with a narrow stile, a mortise lock in an older wood door, or a rim-mounted exit device on a rear service entrance.
Our approach is to repair what can be reliably repaired and replace what cannot. Sometimes a worn latch, a loose strike, or a misaligned door is the real cause of a lock that seems broken. Other times a mortise body or an exit device has simply reached the end of its life. We will tell you which situation you are in and explain the options so you can decide.
How it works in San Dimas
- 1
Call and describe the door
Call (323) 997-8867 and tell us what kind of door it is: glass storefront, aluminum frame, or solid wood or metal with a mortise lock. Tell us what is failing, such as the latch, cylinder, closer, or exit device, and whether the door can currently be secured.
- 2
We come to your business
Because we are fully mobile, a technician travels to your San Dimas location with commercial hardware and tools. If the door will not lock, we start with securing the building so you are not left exposed overnight or over a weekend.
- 3
Diagnose the real cause
Commercial hardware problems are often a chain of causes. We check the cylinder, latch or deadbolt, strike alignment, hinges, door sag, closer adjustment, and the frame itself before recommending a fix, so you are not paying to replace a part that was never the problem.
- 4
Repair or replace
We repair, adjust, or replace storefront locks, mortise bodies, cylinders, push-pull hardware, panic and exit devices, and closers as the situation requires. We explain the options and fit new hardware to the door and frame you already have where possible.
- 5
Test and rekey if needed
We cycle the door repeatedly, check that it latches fully, and confirm keys work smoothly. If staff have left or keys are unaccounted for, we can rekey or set up new keying at the same visit.
- 6
Walk through with you
Before we finish, we show you how the hardware operates and point out any related issues, such as a worn weatherstrip or a door that is beginning to drop, so there are no surprises later.

What affects the price
- The type of door and frame: aluminum storefront, hollow metal, or wood each call for different hardware and installation methods.
- Whether the work is a repair or a full replacement, and how many doors are involved at your location.
- The grade and style of hardware chosen, such as a standard mortise lock versus a heavier-duty exit device or a specialty storefront lock.
- Whether the call is urgent or after hours, and whether the door must be secured right away.
- Keying needs, including rekeying, new keys, or a master key arrangement across several doors.
- Condition of the surrounding door and frame, since sagging or damaged frames may need additional adjustment or parts.

Commercial Door Hardware across San Dimas
San Dimas has a distinct commercial character. Downtown, or Old Town San Dimas, along Bonita Ave is known for its western-themed facades, with small retail shops, restaurants, and civic buildings in a mix of older and updated storefronts. Doors in a district like this can range from original wood doors with mortise locks to newer aluminum-and-glass entries, and the hardware often needs to be fixed in a way that suits the look of the building. ZIP code 91773 covers this core, and we regularly think about how a repair can stay in keeping with the character of a western-style frontage.
Beyond downtown, businesses are spread along Arrow Hwy, San Dimas Ave, Bonita Ave, and Foothill Blvd, with easy access to Interstate 210 and SR-57. Many of these are small offices, service businesses, and shops with rear service doors that take real wear. Near San Dimas Canyon and the area around Frank G. Bonelli Regional Park, properties are often larger and more rural in feel, and gates, barns, and outbuildings can be part of a commercial or equestrian operation that needs durable hardware.
Whether you manage a shop in Old Town, a small office near Via Verde, or a property out toward San Dimas Canyon Park, we can come to you at any hour. Call (323) 997-8867 and we will talk through the door and the problem first.
