A deadbolt is one of the simplest upgrades that actually changes how hard a door is to defeat. Many Palmdale homes, especially the stucco tract subdivisions built from the 1980s through the 2000s, came with builder-grade hardware: a thin bolt, short strike screws, and a strike plate fastened only into the soft door jamb. Replacing or adding a quality deadbolt, and installing it correctly, is often the most practical security step a homeowner can take.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar leads our work. We are fully mobile, so there is no storefront to visit. We come to your home, apartment, or business in Palmdale, assess the door, and install the hardware on site, any hour of the day or night.

This page explains how a deadbolt installation works, what affects the cost, and what is specific to Palmdale: the commuter households around Rancho Vista and Anaverde, rental properties near Palmdale Blvd, and the commercial doors along the Plant 42 corridor and near the Antelope Valley Mall.

How it works in Palmdale

  1. 1

    Talk through the door and the goal

    When you call (323) 997-8867, we ask whether you want to add a deadbolt to a door that has only a knob lock, replace a worn one, or match existing keys. We also ask about the door type: solid wood, hollow core, metal, or an aluminum storefront door.

  2. 2

    Inspect the door, frame, and existing prep

    On site we check the door thickness, the bore holes, the edge prep, and the condition of the jamb. A deadbolt is only as strong as what it is anchored to, so we look for cracked frames, loose hinges, and weak strike mounting before we choose hardware.

  3. 3

    Choose single or double cylinder

    A single-cylinder deadbolt turns with 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 and local fire and safety considerations so you can decide.

  4. 4

    Install and reinforce

    We drill or adjust the holes if needed, fit the bolt and latch, and set the strike plate. Where the frame allows, we use longer screws that reach the wall stud rather than just the jamb, which is a common weakness in tract-home doors.

  5. 5

    Test, key, and hand over

    We cycle the bolt several times with the door open and closed, check alignment, and confirm that every key works. If you want the new deadbolt keyed to match your other locks, we can arrange that, and we walk you through how to use and maintain it.

What affects the price

  • Whether you are adding a new deadbolt to a door with no bore or replacing an existing one, since new boring takes more work than a swap.
  • The grade and brand of hardware you choose, from standard residential models to higher-security options with pick-resistant or drill-resistant features.
  • Single-cylinder versus double-cylinder, and whether you want keyed-alike sets across several doors.
  • Door and frame condition, including material, thickness, and any repairs or reinforcement needed to anchor the lock properly.
  • The number of doors in the job, as multiple locks at one address or across rental units are handled more efficiently in a single visit.
  • The time of day and the location of the job, since we work around the clock and cover a large service area.

Why Palmdale chooses us

  • Fully mobile service: we bring tools and hardware to your Palmdale door instead of asking you to come to a shop.
  • Open 24/7, so a broken lock after a late shift or a break-in repair at night does not have to wait until morning.
  • Experience since 1987, with David Shar as owner and lead technician, working on everything from tract-home doors to commercial storefronts.
  • We focus on installation quality, including strike plate anchoring and alignment, not just swapping a lock in the existing holes.
  • We can handle residential, rental, and commercial hardware, including master-key and restricted-key systems for businesses.
  • We explain options plainly and do not push upgrades the door cannot support.

Deadbolt Installation across Palmdale

Palmdale is spread across a wide stretch of the Antelope Valley, and the housing varies a lot from one part of town to the next. In Rancho Vista and Anaverde, many homes are stucco tract and master-planned houses where the original deadbolt is builder grade. Many households there include aerospace and defense commuters who are often away on long shifts, so a solid deadbolt matters. City Ranch on the west side and the older homes near Downtown Palmdale and Palmdale Blvd often have doors and frames of different ages, which is why we inspect the jamb before choosing hardware. Out toward Lake Los Angeles, large rural lots and longer distances between neighbors make door security a bigger priority.

We work throughout ZIP codes 93550, 93551, 93552, and 93591, including addresses off Rancho Vista Blvd, Avenue S, 10th Street West, and Sierra Highway, and areas reached from CA-14 and CA-138. If you live in Quartz Hill or near 93551, the same mobile service applies.

Property managers near Palmdale Blvd often need several deadbolts replaced or rekeyed between tenants, and businesses near the Antelope Valley Mall or the Plant 42 corridor may need deadbolts on aluminum storefront or back doors. Desert heat can also wear on exterior hardware and electronic keypads over time, so we take that into account when recommending locks for sun-exposed doors. Call (323) 997-8867 any time.

Deadbolt Installation in Palmdale — FAQs

Can you install a deadbolt on a door that only has a knob lock?
Usually yes. If the door is thick enough and solid enough, we can bore a new hole and fit a deadbolt above the knob. We check the door first. Call (323) 997-8867 to describe your 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 be useful near glass but is slower to exit in an emergency. We can help you weigh the two.
Will a new deadbolt help if my door frame is weak?
A deadbolt is only as strong as its mounting. If the jamb is cracked or the strike is only in thin wood, we can reinforce it with a better strike and longer screws so the lock does its job.
Do you install deadbolts at night or on weekends in Palmdale?
Yes. We are 24/7 and fully mobile, so you can call (323) 997-8867 at any hour about a broken lock or a security upgrade.
Can the new deadbolt use the same key as my other locks?
In many cases we can key the deadbolt to match your existing locks, depending on the brand and keyway. Tell us what you have and we will confirm what is possible.
Can you do multiple doors or rental units at once?
Yes. Property managers near Palmdale Blvd and elsewhere often have several doors done in one visit. Mention the number of doors when you call (323) 997-8867.
Do you install deadbolts on commercial doors?
We can work on commercial doors, including many aluminum storefront doors, and can discuss master-key or restricted-key setups. Hardware compatibility depends on the door, so we inspect first.
Do I need to come to a shop to pick a deadbolt?
No. We are mobile only and have no storefront. We bring hardware options to your door and help you choose the right one on site.
