Commerce is mostly warehouses, distribution centers and rail-served industrial property, but a real residential community lives in the pockets between them. In Rosewood Park and Bandini, many homes are small 1940s and 1950s stucco bungalows and post-war tract houses. Plenty of them still have the original knob-in-lockset hardware or a deadbolt that has been turning in the same door for decades. A deadbolt that sticks, spins loosely or never existed in the first place is one of the simplest weak points to fix.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around being fully mobile. We bring the tools and hardware to your door in Commerce, whether that is a bungalow front door, a back entry off an alley, or an office door tucked inside a commercial building. We are available around the clock, which matters when a deadbolt fails at night or a door has to be secured right after a break-in attempt.

This page explains how a deadbolt installation works, what changes the price, how single- and double-cylinder options differ, and what to expect locally. If you are not sure whether you need a new deadbolt, a replacement, or just a rekey of what you already have, call (323) 997-8867 and we will help you sort it out before anyone is dispatched.

How it works in Commerce

  1. 1

    Talk through the door and the problem

    We start with a phone call. Tell us whether you are adding a first deadbolt, replacing a worn one, or upgrading from a knob-only lockset. Describe the door material, whether it has a glass panel nearby, and whether you want a key on both sides. That conversation lets us bring the right hardware.

  2. 2

    Inspect the door, edge and frame

    On site we check the door thickness, the condition of the edge, and the strike area of the jamb. Older bungalow doors in Commerce can have worn bores, painted-over strikes, or soft wood around the old latch. We tell you what we find before any drilling or installation begins.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt uses a key outside and a thumbturn inside. A double-cylinder needs a key on both sides, which can make sense near glass but can slow exit in an emergency. We explain the tradeoffs honestly and help you choose what fits your door and household.

  4. 4

    Install and reinforce the strike

    We prepare the door bore if needed, fit the deadbolt, and install a strike plate so the bolt seats properly in the jamb. Where the frame is tired, we discuss longer screws or reinforcement so the bolt is anchored into the framing, not only the trim.

  5. 5

    Test, key and hand over

    We cycle the bolt several times with the door open and closed, confirm it throws smoothly and fully, and test every key. We then walk you through the operation and leave you with all keys. If you want multiple locks on the property keyed alike, we can discuss that too.

What affects the price

  • Whether you are adding a brand-new deadbolt that needs a bore drilled, or replacing an existing one that already fits
  • Single-cylinder versus double-cylinder hardware, and the security grade and brand of the deadbolt you select
  • Door material and condition, since solid wood, metal and worn older doors each need different preparation
  • The state of the jamb and strike area, including whether reinforcement or frame repair is needed
  • How many doors are being done and whether you want them keyed alike with each other or with existing locks
  • Time of day and urgency, since after-hours emergency calls are handled differently from scheduled work

Deadbolt Installation across Commerce

Commerce is a city of contrasts. Interstates I-5, I-710 and SR-60 frame it, the Citadel Outlets and Commerce Casino draw visitors, and the BNSF Hobart intermodal rail yard anchors a landscape of warehouses and distribution centers. Tucked among them are residential pockets like Rosewood Park, near the park itself, and Bandini, where small stucco bungalows and post-war tract homes still stand. These are the homes where we most often see tired original hardware, loose strikes and doors with only a knob lock.

A typical call might come from a homeowner near Rosewood Park in 90040 whose original 1950s deadbolt has seized in the jamb or stopped throwing fully. Replacing it means checking whether the bore and strike are still sound, since decades of use and repainting can leave them out of alignment. Similar work comes from Bristow Park and the Citadel district, and from ZIP codes such as 90022 and 90023, where homes and small businesses sit close to the busy corridors of Washington Blvd, Atlantic Blvd, Telegraph Rd and Eastern Ave.

Because so much of Commerce is industrial, we also see business owners who want the same sensible upgrades on office entry doors, along with attention to padlocks, gates and panic hardware. Whether you are near the Commerce Library or off a freeway ramp, we come to you. Call (323) 997-8867 any hour and we will talk through the door.

Deadbolt Installation in Commerce — FAQs

Can you install a deadbolt on a door that has never had one?
Yes. If the door is thick enough and in sound condition, we can drill the bore, fit the deadbolt and install a proper strike. We check the door and frame first, and we will tell you if the door itself is a poor candidate. Call (323) 997-8867 to describe it.
My old deadbolt seized in the door. Do I need a full replacement?
Often yes, especially with original hardware from the 1940s or 1950s that has worn internally. We can sometimes free it, but replacement is usually the more reliable fix. This is common in older Commerce bungalows, and we can handle it at any hour.
Should I choose single-cylinder or double-cylinder?
Single-cylinder is the usual choice because you can exit quickly with the thumbturn. Double-cylinder may suit doors with nearby glass but needs a key inside, which can be a hazard in a fire or emergency. We will talk through your door and household before recommending either.
Do you work on businesses in Commerce too?
Yes. Although this page focuses on deadbolts, we serve offices and commercial properties, including doors and padlocks. If you are unsure what your building needs, call (323) 997-8867 and we will advise on the right approach.
Do I need to visit a shop to pick out a deadbolt?
No. We are fully mobile and have no storefront. We discuss options by phone, then bring suitable hardware to your door in Commerce so you can choose with the actual door in front of us.
Will the new deadbolt fit my old door?
Usually, if the door has adequate thickness and the existing bore is intact. Older doors sometimes have worn or oversized holes, which we can often accommodate with the right hardware. We inspect before installing so you know what to expect.
Can the new deadbolt match my other locks?
In many cases, yes. We can discuss keying the new deadbolt to work with your existing keys or other locks so you carry fewer keys. Mention this when you call so we can bring appropriate hardware.
Are you available at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7. If a deadbolt fails, a door will not lock after a break-in attempt, or you are locked out, call us at (323) 997-8867 at any time.
