Lawndale is a compact South Bay city, only about two square miles, and most of it was built in a hurry during the post-war years. That means a lot of 1950s and 60s stucco homes on small lots, plus a large number of 1960s to 80s apartment buildings. On many of those doors, the original builder-grade knob lock and thin deadbolt are still doing the job decades past their service life. A new deadbolt is one of the most practical security upgrades you can make to a door like that.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are a mobile-only business, so there is no storefront to visit. We bring the hardware, drill tools and key-cutting equipment to your home, apartment or shop, and we do the work on site.

Whether you need a first deadbolt on a door that only has a knob lock, a replacement for a worn or sticking unit, or a matched set across several apartments, we will look at the door itself first. The thickness, the condition of the edge and frame, and how the door is used all affect which deadbolt makes sense.

How it works in Lawndale

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us whether the door is exterior or interior, wood, metal or something else, and whether it already has a deadbolt. Mention any security bar, screen door or gate in front of it, since those affect how we work. We are available around the clock.

  2. 2

    On-site door and frame check

    We come to you and inspect the door. We check the thickness, the existing bore holes, the strike plate, and the wood around the frame. On older Lawndale stucco homes, frames are often worn or split, and we point that out before installing anything.

  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 matter for doors with glass nearby but can slow exit in an emergency. We explain the tradeoffs, and you decide. Fire safety and local rules for rentals are worth considering.

  4. 4

    Install and reinforce

    We install the deadbolt, or replace the old one, and align the bolt and strike so it throws smoothly. Where the frame is weak, we can fit a longer-screw or reinforced strike plate so the lock is not just stronger on paper.

  5. 5

    Test, key and hand over

    We cycle the lock repeatedly with the door open and closed, confirm the keys work, and show you how it operates. For multi-unit jobs, we can key locks alike or keep them separate, depending on how access needs to work.

What affects the price

  • Whether we are adding a new deadbolt to a door with no bore or replacing an existing one, since fresh drilling takes more work than a swap.
  • The grade and type of deadbolt you choose, from standard residential units to higher-security hardware, and single versus double cylinder.
  • Door material and condition, including whether a metal, solid wood or hollow door needs extra care or reinforcement.
  • Frame and strike repairs, such as a split jamb or worn strike plate that needs reinforcing for the lock to perform properly.
  • The number of locks, particularly for apartment buildings where several units are done together or keyed alike.
  • Time of day and urgency, since after-hours and same-day calls involve different scheduling than a planned visit.

Why Lawndale chooses us

  • Mobile only, so everything happens at your door and you are not asked to bring the lock or door to a shop.
  • In business since 1987, with owner David Shar leading the work, so experience with older post-war doors and hardware is part of the job.
  • We check the frame and strike, not just the lock, because a deadbolt in a weak jamb does little.
  • We understand security-barred doors common in older Lawndale homes and work around bars and gates to avoid damaging them.
  • We handle multi-unit jobs, including keyed-alike setups for landlords and maintenance access.
  • Honest advice on single versus double cylinder, including when we would not recommend a double-cylinder.

Deadbolt Installation across Lawndale

In Lawndale, the housing mix shapes the work. In El Camino Village and Lawndale Acres, we often see small-lot single-family stucco homes from the 1950s and 60s with original knob locks, aging deadbolts and window security bars. Adding or upgrading a deadbolt there is usually about better hardware and a sturdier strike, with care taken around any bars or gates in front of the door.

Rental density is another factor. Apartment buildings off Inglewood Ave, Marine Ave and Redondo Beach Blvd often need several deadbolts replaced or rekeyed after move-outs, sometimes keyed alike so maintenance can access units. We can plan that as one visit rather than lock-by-lock calls. Along the Hawthorne Boulevard corridor (SR-107), small retail tenants sometimes need a new deadbolt and fresh keys after an employee leaves.

We serve ZIP codes 90260 and 90261, from the area near the Lawndale Civic Center and Lawndale High School to streets close to Alondra Park and Artesia Blvd. Call (323) 997-8867 any hour and we will come to you.

Deadbolt Installation in Lawndale — FAQs

Can you add a deadbolt to a door that only has a knob lock?
Yes. We check the door thickness and edge, drill the proper holes if needed, and fit the deadbolt and strike. Call (323) 997-8867 to describe your door.
Should I choose a single or double-cylinder deadbolt?
Single-cylinder is the usual choice because you can exit quickly without a key. Double-cylinder may suit doors with glass nearby, but it can slow escape in a fire. We explain both before installing.
Do you install deadbolts on doors with security bars?
Yes. Many older Lawndale homes have barred doors or gates. We work around them where possible to avoid damaging the bars, and we will tell you what to expect during the visit.
Can you replace deadbolts at several apartment units at once?
Yes. Landlords often need multiple units done after move-outs. We can install or rekey and set locks keyed alike or individually, depending on your access needs. Call (323) 997-8867 to plan it.
Is my old deadbolt worth replacing or just rekeying?
If it works smoothly and is in good shape, rekeying may be enough. If it sticks, is loose, or is builder-grade and worn, replacing it is usually the better choice. We will give an honest view on site.
Do you offer deadbolt installation at night or on weekends?
Yes, we are available 24/7 and fully mobile, serving Lawndale at any hour.
Can you install a deadbolt on a small shop door on Hawthorne Boulevard?
Yes. We handle storefront and commercial doors as well as residential ones, including new locks and keys after staff changes. Door type affects which hardware works best.
Do I need to be home during installation?
Someone authorized should be present so we can confirm the door, test the lock and hand over keys. For rentals, the landlord or manager can coordinate access.
