A deadbolt is one of the simplest upgrades you can make to a door, and one of the most effective. In Willowbrook, many homes are modest stucco and wood-frame houses built in the 1940s and 50s, and the original locks on them have often been worn down by decades of use. A new deadbolt gives you a solid steel bolt that seats into the frame, rather than relying only on a spring latch that can be slipped or forced.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are fully mobile. There is no storefront to visit; we bring the hardware and tools to your door, whether that is a front door off Central Avenue, a side entry on a small apartment building, or an office door near the medical campus.

Deadbolt work is not always as simple as drilling a hole. Older doors can be thin, previously drilled, or fitted with security screens and bars that change how the door opens. We look at the door, the frame, and the strike area first, then recommend what will actually hold up, including whether a single- or double-cylinder model fits your situation.

How it works in Willowbrook

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what you have: wood or metal door, whether there is already a deadbolt, and whether a security door or window bars are involved. We are available 24/7, so this works after a break-in or late at night too.

  2. 2

    Inspect the door and frame

    On arrival we check the door thickness, condition of the wood or metal, existing bore holes, and the frame and strike plate. On older Willowbrook houses the frame is often the weak point, so we look at it as carefully as the lock.

  3. 3

    Choose the right deadbolt

    We explain the difference between single-cylinder (thumb turn inside) and double-cylinder (key on both sides). Double-cylinder can make sense near glass, but it needs a plan for fast exit in an emergency, so we talk through that honestly with you.

  4. 4

    Install and reinforce

    We install the deadbolt, drilling or fitting into existing holes as appropriate, and set the bolt and strike so it throws smoothly. Where the frame is soft or cracked, we discuss a reinforced strike plate with longer screws that reach the framing.

  5. 5

    Key and test

    We cut or set keys, and can key the new deadbolt to match your existing lock if the hardware allows. We test the door repeatedly, from inside and out, with any security door closed, so you know it operates smoothly.

  6. 6

    Walk through and next steps

    We show you how everything works and mention any other weak points we noticed, such as a loose hinge or an old knob lock. Nothing extra is done without your agreement.

What affects the price

  • Whether you need a new deadbolt on a door with no bore, or a replacement that fits an existing hole
  • Single-cylinder versus double-cylinder hardware, and the grade and finish of the deadbolt you choose
  • Door material and condition, since solid wood, hollow-core, and metal doors are prepared differently
  • Frame and strike reinforcement, which matters on older homes with worn or split door jambs
  • The number of doors, such as a full set for a rental property or several offices
  • Rekeying or keying alike so multiple locks work with one key, and the time of day you need service

Why Willowbrook chooses us

  • Fully mobile service, so the work happens at your door with no trip to a shop
  • In business since 1987, with owner David Shar leading the work
  • Available 24/7, including after a break-in when a door needs securing right away
  • Experience with older door and frame conditions common in mid-century homes
  • Honest advice on single- versus double-cylinder choices, including the emergency-exit tradeoff
  • We work around security doors and window bars rather than ignoring how they affect the entry

Deadbolt Installation across Willowbrook

Willowbrook sits between Compton and Watts, crossed by the I-105 and I-110, with Wilmington Avenue, Central Avenue, Imperial Highway, and Alondra Boulevard carrying most of the traffic. We provide deadbolt installation across ZIP codes 90059, 90061, and 90222, from houses near the Willowbrook/Rosa Parks transit district to homes on quieter side streets.

Much of the local housing is post-WWII single-family stucco and wood-frame homes, plus public and affordable housing and small apartment buildings. A common call is after a break-in on a 1950s house: a new deadbolt, a stronger strike, and a look at the security door and window bars that were added over the years. Another is a rental turnover on a multi-unit property near the Rosa Parks station, where a landlord wants fresh, reliable locks before the next tenant moves in.

We also handle institutional and small commercial doors around the MLK Jr. medical campus and nearby medical offices, where access and rekeying needs differ from a house. Whether you are near Charles R. Drew University, the Earvin 'Magic' Johnson Recreation Area, or the Watts and Compton borders, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Willowbrook — FAQs

Do you install deadbolts in Willowbrook at night?
Yes. We are a 24/7 mobile locksmith. Call (323) 997-8867 any time and we will talk through the door and get you scheduled.
Can you add a deadbolt to a door that only has a knob lock?
Usually, yes. If the door is thick and solid enough, we can bore for a deadbolt and install it above the knob. We check the door first, since very thin or damaged doors may need a different approach.
Should I get a single-cylinder or double-cylinder deadbolt?
Single-cylinder has a thumb turn inside and is easiest in an emergency. Double-cylinder needs a key on both sides, which can help near glass but slows exit. We will explain both so you can decide.
My house is from the 1950s and the door frame looks worn. Is that a problem?
It can be. A new deadbolt is only as strong as the frame holding the strike. We can reinforce the strike area with a stronger plate and longer screws. Call (323) 997-8867 to describe what you see.
Can you work with a security door or window bars?
Yes. Many Willowbrook homes have them. We make sure the deadbolt operates properly with the security door closed and consider how the bars affect how you enter and exit.
Can you key several deadbolts alike for my rental property?
Yes. We can install multiple deadbolts and key them alike, or rekey them between tenants, so one key suits the doors you choose.
Do you handle deadbolts for offices or medical-area buildings?
We do commercial and institutional doors as well, including small offices near the MLK Jr. medical campus. Tell us about the door and access needs when you call (323) 997-8867.
How is the price determined?
It depends on the hardware, door type and condition, frame reinforcement, number of doors, and timing. We explain what affects the cost for your specific door before work starts.
