A deadbolt is one of the simplest upgrades that makes a front door harder to defeat, but only if it is fitted properly. In Thousand Oaks that matters across a wide range of homes: 1960s to 1980s ranch and split-levels around Lynn Ranch and central Thousand Oaks, tract homes throughout Newbury Park, and custom and gated estates in North Ranch and Dos Vientos Ranch. Each has different doors, different frames, and different security needs.

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, whether you are adding a first deadbolt to a side entry, replacing a worn one that sticks, or swapping a single-cylinder for a double-cylinder where the door design calls for it.

This page explains how an installation works, what affects the cost, and what to consider for the kinds of doors common in the Conejo Valley. If you would rather talk it through, call (323) 997-8867 any time of day or night.

How it works in Thousand Oaks

  1. 1

    Talk through the door and your goal

    We start by learning what you want: a new deadbolt where there is only a knob lock, a replacement for a failing one, or a stronger setup after a move or break-in. We ask about the door material, whether it has glass nearby, and who needs to use it.

  2. 2

    Inspect the door, bore holes, and frame

    On site we check the door thickness, the existing holes, the edge, and the strike area of the frame. Solid wood, steel, and fiberglass doors each need different handling, and an older door may have been drilled before. This tells us what will fit cleanly.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt turns with a thumbturn inside and a key outside. A double-cylinder needs a key on both sides, which can make sense near glass panels or sidelights, but it affects how quickly people can leave in an emergency. We explain the tradeoff so you decide with full information.

  4. 4

    Install and reinforce the strike

    We fit the deadbolt, set the latch and bolt alignment, and install the strike plate in the frame. Where the frame looks weak, we discuss longer screws or a reinforced strike so the bolt is anchored to the structure and not just the trim.

  5. 5

    Test, key up, and hand over

    We cycle the lock repeatedly with the door open and closed, confirm the bolt extends fully, and make sure the keys work smoothly. We can key the new deadbolt to match your other locks where the hardware allows, and we show you how everything operates.

What affects the price

  • Whether this is a new installation that requires drilling a fresh bore or a replacement that uses existing holes.
  • The grade and brand of deadbolt you choose, from standard residential hardware up to high-security cylinders.
  • Single-cylinder versus double-cylinder, and whether several doors should be keyed alike.
  • Door material and condition, since steel, fiberglass, solid wood, and older doors can need extra prep or repair.
  • Frame reinforcement, such as a stronger strike plate or longer screws, if the existing frame is weak.
  • The time of day and the location of the job, since we are available around the clock and travel to you.

Why Thousand Oaks chooses us

  • Fully mobile service: everything is done at your door, with no storefront trip and no need to bring the door anywhere.
  • Serving the area since 1987, so we have seen the door and frame types common in older ranch homes and newer tract and custom builds.
  • We explain single versus double cylinder honestly, including the safety tradeoff, instead of pushing the option that costs more.
  • We look at the frame and strike, not just the lock, because a deadbolt is only as strong as what it is anchored to.
  • Available 24/7, so a broken or failed deadbolt does not have to wait until morning.
  • The owner, David Shar, leads the work and the standards behind it.

Deadbolt Installation across Thousand Oaks

Thousand Oaks housing varies enough that the right deadbolt depends on the neighborhood. In Lynn Ranch and the older parts of central Thousand Oaks near Thousand Oaks Blvd and Moorpark Rd, many 1960s to 1980s ranch and split-level homes still have original door hardware that has worn out or was never upgraded. Newbury Park has extensive tract housing, where homes often share similar door sizes and a new owner may want a fresh deadbolt after buying. Many residents in 91320 and 91360 call us for exactly this kind of update.

Further north and west, North Ranch and Dos Vientos Ranch include higher-end gated and custom estates. These often have heavier doors, multipoint European-style locks, and high-security cylinders, so we talk through compatibility before adding or changing a deadbolt. Hillside custom homes throughout the Conejo Valley can also have unusual door sizes, and we plan the work around what is actually on your door. We also serve homes in 91362, 91358, and 91359.

We travel the area on US-101, SR-23, Hampshire Rd, Lynn Rd, and Borchard Rd, reaching homes near spots like Wildwood Regional Park, California Lutheran University, and The Oaks mall. Because we are fully mobile and 24/7, you can reach us at (323) 997-8867 whenever a door needs attention, with no store to visit.

Deadbolt Installation in Thousand Oaks — FAQs

Can you install a deadbolt on a door that only has a knob lock?
Usually, yes. We check the door thickness and edge to confirm a deadbolt will fit, then drill the needed holes and install it. Call (323) 997-8867 and describe the door.
What is the difference between single- and double-cylinder deadbolts?
A single-cylinder uses a key outside and a thumbturn inside. A double-cylinder needs a key on both sides, which can help near glass but slows exit in an emergency. We help you weigh that for your door.
Do you replace old deadbolts in Newbury Park tract homes?
Yes. Replacing a worn or sticking deadbolt is common in Newbury Park, and we can often reuse the existing holes. We can also key it to match your other locks where hardware allows.
Can a deadbolt fit a high-end door in North Ranch or Dos Vientos?
Often, but these doors can have multipoint or high-security hardware that changes what works. We assess the door first and explain what we recommend before installing.
Will a new deadbolt stop a break-in if the frame is weak?
A deadbolt is only as strong as its anchor. We inspect the frame and strike and can suggest a reinforced strike or longer screws to make the installation more effective.
Do you offer deadbolt installation at night or on weekends?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 at any hour. We do not make timing promises, but we will confirm availability when you call.
How is the price of a deadbolt installation determined?
It depends on whether this is a new install or replacement, the deadbolt grade, the door material and condition, any frame reinforcement, and the time and location. We explain the factors when you call.
Can you key my new deadbolt to match my existing locks?
In many cases, yes, depending on the brands involved. Tell us what locks you have when you call (323) 997-8867, and we will let you know what is possible.
