A business door takes more punishment than almost any other part of a building. It opens and closes hundreds of times a day, gets leaned on, slammed and propped, and it has to lock reliably every night. When the hardware starts to fail, you usually notice it in small ways first: a latch that needs a shoulder to catch, a closer that slams, a thumbturn that spins without engaging, or a key that only works if you jiggle it.
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 kinds of doors Covina businesses actually have. Those range from aluminum-frame storefronts with narrow stiles to heavier mortise lock setups on older buildings. We are a mobile-only service. There is no storefront to visit, because we bring the tools and the know-how to your door.
This page explains how commercial door hardware work usually goes in Covina, what drives the cost, and what to expect when you call. We do not quote prices without seeing the door, because the right fix depends on the frame, the existing hardware and how the door is used.
How it works in Covina
- 1
Call and describe the door
Call (323) 997-8867 any hour. Tell us what type of door it is (aluminum storefront, wood, hollow metal), what is failing, and whether the door is currently secure. If it cannot be locked, we treat that as a priority.
- 2
On-site inspection
We come to your location and look at the whole assembly: lock or latch, cylinder, strike, hinges, closer, panic or exit device, and the door and frame alignment. Many hardware complaints are really alignment or wear problems, so we check before replacing anything.
- 3
Repair or replace, with a clear recommendation
If a part can be adjusted or rebuilt, we say so. If the hardware is worn out, mismatched or no longer supported, we explain the replacement options and how each fits your frame, your budget and your security needs.
- 4
Installation and fitting
We install and fit the hardware to the door, whether that is an aluminum-frame storefront lock, a mortise lockset, or a new cylinder. We make sure the latch throws fully, the strike lines up and the door closes under its own control.
- 5
Keying and key control
We can key new cylinders to your existing system or set up a fresh one. This is a good moment to account for who holds keys, especially after staff changes or a change in tenant.
- 6
Test and walk-through
Before we leave, we operate the door with you several times, from both sides, and confirm it locks and unlocks smoothly. You leave knowing what was done and how to care for it.

What affects the price
- Door and frame type: narrow-stile aluminum storefront doors, wood doors and hollow metal doors each call for different hardware and installation methods.
- Repair versus replacement: adjusting or rebuilding existing hardware generally costs less than replacing an entire mortise lock body or exit device.
- Hardware grade and finish: heavy-duty commercial-grade locks, panic devices and closers vary widely depending on brand, rating and finish.
- Number of doors and keying needs: a single door differs from a multi-door job, and a master key or restricted keyway system adds work.
- Condition of the door and frame: sagging, misaligned or damaged doors may need correction so new hardware works correctly.
- After-hours or urgent service: a call outside regular business hours or one that involves an unsecured business may be priced differently than a scheduled visit.
Why Covina chooses us
- Fully mobile and available 24/7, so a failed storefront lock does not have to leave your business open overnight.
- In business since 1987, with hands-on experience across older mortise hardware and modern aluminum storefront systems.
- Owner-led: David Shar leads the work, so there is clear accountability for what is installed.
- We check alignment and wear before recommending replacement, so you are not sold new hardware for a problem that needs an adjustment.
- No storefront overhead to explain: we come to you, and we give an honest assessment on site rather than a guess over the phone.
- Keying options that fit your situation, from matching existing keys to setting up a cleaner system after an employee or tenant change.
Commercial Door Hardware across Covina
Covina has a mix of business environments, and the hardware needs differ between them. Historic Downtown Covina along Citrus Ave has 1920s and 1930s commercial buildings, many with older frames, original or retrofitted mortise hardware and doors that have been repainted, rehung and adjusted over many years. Shops and offices near the Covina Center for the Performing Arts and Heritage Plaza often need hardware that works well on these older doors while still meeting modern security expectations. A business in the 91723 ZIP code, for example, might be running aging hardware on a door that was never designed for today's traffic.
Outside the downtown core, businesses along Azusa Ave, Grand Ave, Badillo St, San Bernardino Rd and Arrow Hwy tend to have aluminum-frame storefront doors with commercial cylinders, closers and push-bar or panic hardware. These are common in the 91722 area, and they wear in predictable ways: loose rails, worn pivots, tired closers and cylinders that start to stick. Properties near the Covina Metrolink station and the I-10 corridor see steady foot traffic, which tends to wear hardware faster.
We also serve Charter Oak (91724) and the Covina Hills area to the south, where small offices, home-based businesses and larger properties have their own needs. Because we are mobile, we can reach any of these areas directly. Call (323) 997-8867 and tell us the address and the door, and we will take it from there.
