A deadbolt is one of the simplest ways to make a door harder to defeat, but only when it is fitted properly. In East Los Angeles, where so many homes are small-lot bungalows and stucco houses from the 1920s through the 1940s, the original hardware is often worn, loose, or missing a real deadbolt altogether. A new bolt set into a sound door and a solid strike plate changes how the whole entry behaves.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen just about every kind of older door these neighborhoods have to offer. We are fully mobile. We bring the tools and hardware to your property, look at the door in front of us, and install or replace the deadbolt on site.

Whether you want a first deadbolt on a bare entry door, a replacement for a sticky or worn one, or a keyed-alike set for a house and a back unit, we will explain the options in plain language. Single-cylinder and double-cylinder models suit different situations, and we will help you choose rather than push one over the other.

How it works in East Los Angeles

  1. 1

    Call and describe the door

    Call (323) 997-8867 any hour. Tell us whether the door is wood, metal, or a security screen setup, whether you want a new deadbolt or a replacement, and whether other locks should match.

  2. 2

    We come to you

    Because we are fully mobile, a technician travels to your home or business in East Los Angeles with hardware and tools. There is no shop to visit, and we do not make arrival-time promises we cannot keep.

  3. 3

    Inspect the door and frame

    We check the door thickness, the condition of the edge, and the frame and strike area. Older bungalow doors are often worn or have been drilled before, so we look for what the new bolt will actually be anchored into.

  4. 4

    Choose single or double cylinder

    We explain the difference. A single cylinder turns with a thumb-turn inside, which is easy to exit. A double cylinder needs a key on both sides, which suits doors beside glass but needs careful thought about emergency exit.

  5. 5

    Install and reinforce

    We prepare the door, fit the deadbolt, and set the strike plate so the bolt throws smoothly and engages the frame. Where the frame looks weak, we talk through reinforcement options.

  6. 6

    Test and hand over keys

    We operate the bolt repeatedly with the door open and closed, confirm it aligns, and hand over your keys. If you want keyed-alike across several doors, we set that up at the same visit.

What affects the price

  • Whether you need a brand new installation that requires drilling the door or a straight replacement of an existing deadbolt
  • The grade and style of deadbolt you choose, from standard residential models to heavier-duty options
  • Door material and condition, since solid wood, hollow metal, and worn older doors each take different work
  • Whether the frame or strike area needs reinforcing or repair so the bolt actually protects the door
  • How many doors or locks are involved, including keyed-alike setups across a house and back unit
  • Time of day and urgency, since after-hours and emergency calls are handled differently from scheduled visits

Why East Los Angeles chooses us

  • Fully mobile service: we work at your door instead of asking you to bring anything to a shop, because there is no storefront
  • Available 24/7, so a broken or missing deadbolt after a break-in attempt does not have to wait until morning
  • Experience since 1987 with older Los Angeles doors, including worn bungalow entries and previously drilled edges
  • Honest guidance on single versus double cylinder, including the exit-safety tradeoffs rather than a default upsell
  • Comfortable with keyed-alike work for houses with converted garages or back-house units
  • Attention to the strike plate and frame, not just the bolt, because that is where many failures happen

Deadbolt Installation across East Los Angeles

East Los Angeles is a dense, working-class unincorporated community, and much of its housing is small-lot bungalows and stucco houses built in the 1920s to 1940s. In Belvedere and City Terrace, we often see original or long-worn hardware on front doors, plus steel security screen doors with their own keyed locks. A deadbolt installed here usually means thinking about two locks at once: the screen door and the main entry, so the doors work together and you are not juggling mismatched keys.

Maravilla and Eastmont have their own mix of older houses, fenced lots, and converted garages or back houses. A landlord with a 1930s house and a rear unit may want every entry keyed alike so one key works the right doors after a tenant moves out. We can install new deadbolts and set up that arrangement in a single visit at properties across ZIP codes 90022, 90023, and 90063.

We also understand the small businesses along Whittier Boulevard, Cesar Chavez Avenue, and Atlantic Boulevard, where aluminum storefronts and roll-down security gates are common. Our focus on this page is deadbolts, but if a shop has a stubborn gate padlock or needs a back-door deadbolt, call (323) 997-8867 and we will tell you what we can do. Whether you are near City Terrace Park, the East LA Civic Center, or close to the freeway interchange, we come to you.

Deadbolt Installation in East Los Angeles — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. We can prepare the door and fit a new deadbolt where there was only a knob or handle lock. Call (323) 997-8867 and describe the door so we can bring suitable hardware.
Should I choose a single or double cylinder deadbolt?
A single cylinder uses a thumb-turn inside and is easier to exit quickly. A double cylinder needs a key on both sides, which can help near glass but can slow an emergency exit. We will talk through your door and household before you decide.
My bungalow's original door looks worn. Can it take a new deadbolt?
Often yes, but we inspect it first. Older doors may have been drilled before or have a worn edge. We check the door and frame on site and tell you honestly what will hold.
I have a security screen door with its own lock. Can you work on both?
Yes. Many homes in Belvedere and City Terrace have steel screen doors with keyed locks. We can service or replace the main deadbolt and discuss the screen door lock during the same visit.
Can you make several locks keyed alike?
Yes. This is common for a house plus a converted garage or back unit. We can set up deadbolts so the right doors share a key, which is handy for landlords after a tenant leaves.
Do I have to come to a shop?
No. Crenshaw Lock Company is fully mobile and has no storefront. We come to your home or business in East Los Angeles.
Are you available at night or on weekends?
Yes, we are available 24/7. If your deadbolt is broken or your door will not secure, call (323) 997-8867 at any hour.
Will a deadbolt alone make my door secure?
It helps a great deal, but the strike plate, frame, and door condition matter too. We look at all of them and suggest reinforcement where it makes sense.
