A deadbolt is only as good as the door and frame around it. In Westmont, where many homes are small stucco bungalows built between the 1920s and 1950s, we often find original knob locks worn smooth, loose strike plates, and doors that have been repainted and re-hung several times. Adding a quality deadbolt, set correctly into the door and anchored into the framing, is one of the most practical security upgrades a household here can make.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has worked on every type of older door this area offers. We are fully mobile, so there is no storefront to visit. We bring the hardware and tools to your door, whether that is a front door on a quiet side street, a rear door of a duplex, or a unit in a small apartment building.

Some calls are planned upgrades and some follow a bad night, like a break-in or a lost set of keys. Either way, we look at how the door is built, what the existing bore and edge prep allow, and what will realistically hold up. Then we install a deadbolt that fits your door, your household, and how you use the entry, and we explain the choices in plain language, including single versus double cylinder.

How it works in Westmont

  1. 1

    You call, we talk through the door

    Call (323) 997-8867 any hour. Tell us whether you want a new deadbolt added, an old one replaced, or a break-in repaired. Describe the door material, whether it has glass nearby, and any existing hardware, so we arrive prepared.

  2. 2

    Inspect the door and frame

    Our technician checks the door thickness, the existing bore holes, the edge condition, and the jamb. On older bungalow doors we look for splitting, soft wood, and short strike plate screws that would let a kick defeat even a good lock.

  3. 3

    Choose the right cylinder type

    We explain single-cylinder (thumbturn inside) versus double-cylinder (key on both sides). A double cylinder can make sense near glass but has fire-egress tradeoffs, so we talk through your situation before installing either.

  4. 4

    Install and reinforce

    We drill or reuse bores cleanly, set the latch and bolt, and mount the strike with longer screws that reach the framing. If the door or jamb is damaged, we discuss a reinforced strike plate or a repair before the lock goes in.

  5. 5

    Test, key, and walk through

    We operate the bolt repeatedly with the door open and closed, check alignment, and confirm the keys work smoothly. We can key the new deadbolt to match your existing lock when the hardware allows, then hand over the keys.

What affects the price

  • Whether you need a brand-new deadbolt installed or an existing one replaced, since new installs may require drilling and edge prep.
  • The grade and brand of the deadbolt you select, from standard residential hardware to higher-security options.
  • Door material and condition, including wood, hollow-core, metal, or a door that was damaged in a break-in.
  • Extras such as a reinforced strike plate, jamb repair, or additional locks keyed alike across several doors.
  • Number of doors being done in one visit, such as front and back doors, or multiple units in a duplex.
  • The time of day and urgency of the call, since we operate 24/7 and after-hours service differs from scheduled work.

Why Westmont chooses us

  • We have been a locksmith in Greater Los Angeles since 1987, so older bungalow doors and worn frames are familiar territory.
  • We are fully mobile and work at your door, with no storefront and no need to bring the door anywhere.
  • We look at the frame and strike, not just the lock, because a deadbolt on a weak jamb gives false confidence.
  • We explain single versus double cylinder honestly, including safety and egress concerns, rather than just selling the more expensive option.
  • We can handle the follow-up work after a break-in, from lock replacement to reinforcement, in one visit when possible.
  • We are available 24/7, so you can have a door secured the same night you discover a problem.

Deadbolt Installation across Westmont

Westmont sits in unincorporated Los Angeles County, and its housing tells the story of why deadbolts matter here. Along the Western Avenue corridor and the Vermont Avenue corridor, you find dense blocks of 1920s to 1950s stucco homes and California bungalows on modest lots, mixed with duplexes and small apartment buildings. Many still carry original locks that have been worn down over decades. In ZIP code 90047 and ZIP code 90044, we regularly see doors where a deadbolt was never added or where a cheap one was fitted with short screws.

Our work reaches neighboring areas too, including Vermont Knolls and West Athens, where similar older housing is common. A typical call is a post-break-in replacement on a 1940s bungalow, often paired with a reinforced strike plate or a security door. Another is a duplex or small apartment unit where a landlord wants a fresh deadbolt after tenant turnover.

We also know the commercial side of the area. Along Western Avenue, Vermont Avenue, and the Imperial Highway commercial strip, mini-malls, markets, and auto shops often rely on roll-down security gates and high-security locks. Whether you live near Jesse Owens Community Regional Park, close to Washington Preparatory High School, or off the Vermont and Manchester corridor, we come to you. Call (323) 997-8867 any time.

Deadbolt Installation in Westmont — FAQs

Can you install a deadbolt on a door that never had one?
Yes. We drill the proper bore and edge holes, set the latch and bolt, and mount the strike plate. We check the door thickness and condition first. Call (323) 997-8867 to describe your door.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder has a thumbturn inside and is easier to exit quickly in an emergency. Double-cylinder needs a key on both sides, which can help if there is glass nearby but raises egress concerns. We go over both with you before installing.
My Westmont bungalow door is old and the wood is worn. Can it still take a deadbolt?
Often yes. We inspect the door and jamb for splitting or soft spots. If the wood is too damaged, we may recommend repair, reinforcement, or a replacement door before adding the lock.
Do you offer deadbolt installation at night or on weekends?
Yes, we are available 24/7 and fully mobile. If you need a door secured after a break-in or a lost key, call (323) 997-8867 at any hour.
Will a deadbolt alone stop a forced entry?
A good deadbolt helps a lot, but the strike plate and door frame matter just as much. We often install a reinforced strike plate with longer screws that reach the framing so the door resists kicking.
Can you key the new deadbolt to match my existing lock?
In many cases we can key it alike so one key works both. It depends on the brand and keyway of your current lock. We will tell you what is possible when we inspect the door.
I manage a duplex in Westmont. Can you do several doors at once?
Yes. We can install or replace deadbolts on multiple doors in one visit and can key them as needed for each unit, which is useful after tenant turnover.
Do I need to come to a shop for service?
No. Crenshaw Lock Company is mobile only, so we come to your home or business anywhere in Westmont with the tools and hardware.
