A shop door is the most-used piece of equipment in a small business. It opens and closes all day, takes abuse from wind, weight and hurried hands, and when it fails it can leave you unable to open on time or unable to lock up at night. In a compact town like Sierra Madre, where the storefronts around Kersting Court and along Sierra Madre Blvd sit close together and depend on foot traffic, a sticking latch or a loose handle is not something you want to live with for long.

Crenshaw Lock Company has served Los Angeles and Ventura Counties since 1987, led by owner and lead technician David Shar. Our commercial door hardware work covers the common problems on storefront and aluminum-frame doors: worn or failing locksets, broken push bars and pull handles, misaligned strikes, tired closers and hinges, and mortise lock bodies that have worn out or seized. We repair what can reasonably be repaired and replace what cannot, and we tell you which is which.

We are fully mobile. There is no storefront to visit; we bring tools and common hardware to your door, whether that is a cafe near the village core, a small office, or a business with an older door that does not match modern off-the-shelf parts. We are available around the clock, so a hardware failure at closing time does not have to mean leaving your business unsecured overnight.

How it works in Sierra Madre

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what the door is doing: not latching, key will not turn, handle loose, door not closing, or something broken. Let us know whether it is a glass storefront door, an aluminum-frame door, or a mortise-style door in an older building. That helps us bring suitable parts.

  2. 2

    Assess the hardware and the door

    On site we look at more than the lock itself. Many hardware complaints come from a door that has dropped on its hinges, a closer that is slamming or too weak, or a strike that no longer lines up. We check how the door hangs and swings before deciding what actually needs work.

  3. 3

    Explain repair versus replacement

    We lay out the options plainly. Sometimes adjusting, tightening or replacing a single part solves it. Other times a worn mortise body, a cracked handle or a failing lockset is better replaced. You decide, with an honest picture of what each path involves.

  4. 4

    Do the work and secure the opening

    We install or repair the hardware, align the latch and strike, and make sure the door closes and locks without force. If the door cannot be fully fixed in one visit, we make it secure for the night so your business is protected.

  5. 5

    Test, key and hand over

    Before we leave we operate the door repeatedly, test every key, and confirm it works the way your staff will actually use it. If keys need to be cut or the cylinders rekeyed as part of the job, we take care of that too.

What affects the price

  • The type of door: glass storefront, aluminum-frame and mortise doors all use different hardware and take different amounts of labor.
  • Whether the problem is a repair, such as an adjustment or a single replaced part, or a full replacement of the lockset, handle set or mortise body.
  • The grade and style of hardware you choose, including finish, handing and any need to match existing hardware.
  • Availability of parts for older or non-standard doors, which can affect whether we can match what is there or must adapt it.
  • Time of day and urgency, since after-hours and emergency calls are handled differently than scheduled work.
  • Extra work such as rekeying, key duplication, closer or hinge replacement, or aligning a door that has shifted.

Why Sierra Madre chooses us

  • Mobile service, 24/7: we come to your business at any hour instead of asking you to bring anything anywhere.
  • Operating since 1987, with an owner-led approach under David Shar, so experience with older and unusual hardware is part of the job.
  • We diagnose the whole door, not just the lock, so you are not paying to replace a lockset when the real issue is alignment or a worn closer.
  • Comfortable with mortise hardware, including older bodies that are not a simple swap, and with aluminum-frame and storefront doors.
  • Straightforward repair-or-replace advice, with no pushing a replacement when a repair will serve you.
  • We make the door secure before we leave, even if a final part still has to be ordered.

Commercial Door Hardware across Sierra Madre

Sierra Madre is a small, walkable foothill town, and its business life centers on the village core. Around Kersting Court and the shops nearby, doors are in constant use, and many sit in older buildings where the hardware does not match modern standard sizes. We work with businesses in Downtown Sierra Madre in ZIP code 91024 as well as those toward the eastern side of town in 91025, along Sierra Madre Blvd, Baldwin Ave and Michillinda Ave.

Older buildings bring their own challenges. A door that has been rehung several times, an original mortise lockset, or a storefront frame that has settled over decades can make a simple-sounding repair more involved. We take the time to see how the door really behaves and choose hardware that fits it rather than forcing a mismatched part.

Because we are mobile only, there is no shop to visit. We come to you, whether you are near the wisteria vine, close to Mary's Market, or up in Sierra Madre Canyon, where narrow, steep lanes can mean parking below and carrying tools up on foot. We plan for that. If you are in Sierra Madre and a door is not working, call (323) 997-8867.

Commercial Door Hardware in Sierra Madre — FAQs

What kinds of commercial doors do you work on in Sierra Madre?
We repair and replace hardware on storefront doors, aluminum-frame doors and mortise-lock doors, including the older wood and metal doors found in the village core. Call (323) 997-8867 and describe the door.
Do you offer 24/7 service for commercial door problems?
Yes. We are available 24/7 and fully mobile. If a door will not lock or close at night, call (323) 997-8867 and we will work to get your business secured.
Can you fix my door instead of replacing the hardware?
Often yes. Many problems come from loose fasteners, misalignment, a worn strike or a tired closer. We assess the door first and only recommend replacement when repair is not a sensible answer.
Can you work on older mortise locks in Sierra Madre buildings?
We work with mortise hardware, including older bodies. Whether we can repair or must replace depends on condition and parts availability, and we will explain which applies to your door.
How is commercial door hardware pricing determined?
Price depends on the door type, whether it is a repair or replacement, the hardware grade and finish, parts availability, urgency and any added work like rekeying. We do not quote prices on this page; call (323) 997-8867 to discuss your situation.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your business in Sierra Madre rather than operating a storefront.
My door will not close properly or slams. Is that a hardware issue?
Frequently, yes. A closer that is out of adjustment or failing, worn hinges or a door that has sagged can all cause it. We check these along with the lock.
Can you rekey the locks at the same time as the hardware work?
Yes. If you want new keys, a rekey after a staff change, or matching cylinders across doors, we can do it during the same visit.
