A deadbolt is one of the simplest upgrades you can make to a door, and also one of the easiest to get wrong. The bolt may be fine while the strike plate is held by short screws into soft door framing. The lock may be new while the door itself is hollow near the latch. When we install a deadbolt in Norwalk, we look at the whole door, not only the hardware you picked up at the store.

Much of Norwalk was built in the late 1940s and 1950s, when the aerospace boom filled the area with single-story stucco ranch and minimal-traditional homes. Many of those houses still have their original mid-century Kwikset or Weiser entry sets, and aging tubular deadbolts that stick, spin loosely or no longer turn at all. Replacing one is often a quick, satisfying fix. Sometimes the old bore or door edge needs careful attention so the new bolt sits square and throws all the way.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We bring the work to your door, day or night, whether you want a first deadbolt on a back door, a replacement for a worn cylinder, or a rekeyed set across several apartment units.

How it works in Norwalk

  1. 1

    Call and describe the door

    Call (323) 997-8867 and tell us what you have: a front door on a tract home, a rear service door, an apartment entry, or a patio door. Mention whether you want a single-cylinder (thumbturn inside) or double-cylinder (key on both sides) deadbolt, and whether the old lock is stuck or just worn.

  2. 2

    Inspect the door and frame

    On site, we check door thickness, material, the existing bore holes, and the condition of the jamb. Older doors can be dried out, painted over many times, or slightly out of square, and these details decide how the new deadbolt should be fitted.

  3. 3

    Choose the right hardware

    We go over deadbolt options with you and explain the trade-offs. A double-cylinder can make sense where there is glass near the lock, but it requires thought about emergency exit, so we talk through that honestly before anything is installed.

  4. 4

    Install and reinforce

    We fit the deadbolt, correct or drill the bore if needed, and set the strike plate. Where the frame is weak, we reinforce it with proper long screws into the framing so the bolt is backed by more than thin trim wood.

  5. 5

    Test, key and hand over

    We cycle the bolt repeatedly with the door open and closed, check alignment, and confirm that every key works smoothly. You get your keys, and we can key the new deadbolt to match your other locks so you carry fewer keys.

What affects the price

  • Whether you are adding a brand-new deadbolt or replacing an existing one, since a new install may require drilling and an old one may reuse existing bores.
  • The grade and type of deadbolt you choose, including single- versus double-cylinder and the security rating of the hardware.
  • The condition of the door and frame, including whether the strike area needs reinforcement or an old bore needs correcting.
  • How many doors or units are being done in one visit, which matters for apartment buildings and multi-door properties.
  • Whether the work includes rekeying to match existing keys or setting several locks to the same key.
  • The time of day you call, as after-hours and overnight service is part of our 24/7 mobile availability.

Why Norwalk chooses us

  • Fully mobile, so the whole job happens at your door with no trip to a shop and no storefront to find.
  • Serving Greater Los Angeles and Ventura County since 1987, with deep familiarity with the mid-century hardware found in older Southern California homes.
  • Owner and lead technician David Shar stands behind the work, so it is not handed off to an anonymous crew.
  • We inspect the door and strike, not only the lock, because a strong deadbolt in a weak frame does little.
  • We explain single- versus double-cylinder trade-offs plainly, including the safety side of keyed-both-sides locks.
  • Available 24/7, which helps when a seized deadbolt leaves you locked out or a departing employee means a lock needs changing right away.

Deadbolt Installation across Norwalk

Norwalk's housing tells you what to expect from its locks. Around Carmenita and the Carmenita Road area, and in the neighborhoods near Cerritos College and Studebaker Road, you'll find the stucco tract homes from the 1950s, many with their original deadbolts still in service. A seized bolt where the key no longer turns is a common reason a homeowner near the college calls, and replacement is usually the right answer rather than coaxing a worn tubular lock along.

Along Pioneer Blvd, Firestone Blvd and Rosecrans Ave, the 1960s and 70s stucco dingbat apartment buildings bring a different job. Landlords there often need deadbolts replaced or rekeyed on tenant turnover, with worn Kwikset cylinders swapped out and aluminum sliding patio doors on original mortise latches reviewed for added security. We can work through multiple units in one visit.

We also serve the Norwalk Civic Center and Town Square district, including small businesses that need after-hours work, and homes and apartments in ZIP codes 90650, 90651 and 90652. Whether you are near Metropolitan State Hospital, close to the Norwalk Metro C Line Station or the Norwalk/Santa Fe Springs Metrolink Station, or just off I-5 or I-605, call (323) 997-8867 and we will come to you.

Deadbolt Installation in Norwalk — FAQs

Can you install a deadbolt on a door that doesn't have one?
Yes. If the door is suitable, we drill the bore and edge, install the bolt and strike, and reinforce the frame. Call (323) 997-8867 to describe your door and we can tell you what to expect.
My old deadbolt in my 1950s Norwalk home won't turn. Should I replace it?
Often yes. Mid-century tubular deadbolts wear out inside, and forcing the key can snap it. We can get you inside and install a new deadbolt in the same visit. Call (323) 997-8867 any hour.
Should I choose a single- or double-cylinder deadbolt?
Single-cylinder locks use a thumbturn inside, which makes exit fast in an emergency. Double-cylinder locks need a key on both sides and may suit doors with nearby glass, but they carry exit risks. We'll talk through your door before you decide.
Can you rekey the new deadbolt to match my other locks?
In most cases, yes. We can key the new deadbolt to your existing key so one key works on multiple doors, which cuts down the keys you carry.
I manage a dingbat apartment building off Pioneer Blvd. Can you handle several units?
Yes. We can replace worn cylinders, install deadbolts and rekey units on turnover in one visit. Calling ahead to (323) 997-8867 with a unit count helps us plan the work.
Do you install deadbolts for small businesses in Norwalk?
We do, including after-hours rekeys and deadbolt upgrades for shops, such as after an employee leaves. Call (323) 997-8867 and tell us about the door.
Do I need to come to a shop to pick a deadbolt?
No. We are fully mobile and have no storefront. We come to you, look at your door, and help you choose hardware on site.
Will a new deadbolt actually make my door more secure?
It helps, especially when paired with a reinforced strike and solid door. We check those parts too, because a deadbolt is only as strong as what it's anchored to.
