Many Norwalk homes were built in the late 1940s and 1950s, during the aerospace boom that filled the area with single-story stucco ranch and minimal-traditional houses. A lot of those front doors still carry mid-century Kwikset or Weiser entry sets and tubular deadbolts that have been turned thousands of times. Springs weaken, cylinders wear smooth, keys get copied from copies, and eventually one stops turning at the worst moment.

Lock replacement means taking out hardware that is worn, damaged, outdated or simply no longer trustworthy, and installing new hardware keyed the way you need it. That can be a single deadbolt on a tract home, a handle set that no longer latches, or a whole run of cylinders in an apartment building. It is different from rekeying, which changes the inside of a lock you are keeping. Sometimes rekeying is enough, and we will say so when it is. Sometimes the lock is past saving, and replacing it is the honest answer.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no storefront to visit. We bring the work to your door, at any hour, and explain the options before we start.

How it works in Norwalk

  1. 1

    Call and describe the problem

    Phone us at (323) 997-8867 any time of day or night. Tell us what the lock is doing: stuck, loose, key spinning, damaged after a break-in attempt, or just old. We ask about the door type and whether you are locked out so we can bring the right hardware.

  2. 2

    Assess the door and the existing hardware

    On site, we look at the lock, the strike plate, the bore holes and the door edge. On older Norwalk tract homes, the door itself is often fine and only the deadbolt or knob has failed. On aluminum sliding patio doors, we check whether the original latch can be replaced or needs a different solution.

  3. 3

    Walk through your options

    We explain whether rekeying, repairing or fully replacing makes sense, and what grade and style of hardware fits your door and your priorities. You decide before any work begins, so nothing is a surprise.

  4. 4

    Remove the old lock and install the new one

    We take out the worn hardware, check that the door is prepared properly, and install the new lock so the bolt throws cleanly into the frame. If a seized lock has locked you out, we get the door open first, then replace the lock.

  5. 5

    Key, test and hand over

    We cut or set the keys, then test the lock repeatedly with the door open and closed. You get all keys, and we show you how to operate any special features. For multiple units we can key sets to match your needs.

What affects the price

  • How many locks are being replaced, since a single deadbolt is a different job from a full apartment building turnover
  • The type and grade of hardware you choose, from basic residential sets to heavier-duty deadbolts and handle sets
  • Whether the door, strike plate or frame needs adjustment or repair for the new lock to fit and work properly
  • Whether you are locked out or the lock has seized, which can require entry work before replacement
  • The time of day, with after-hours, weekend and holiday calls handled differently from scheduled daytime visits
  • Whether you want new locks keyed alike, on a master key system, or each keyed separately

Why Norwalk chooses us

  • Fully mobile, so we work at your door with the hardware on the truck, with no shop trip in the middle of the job.
  • Available 24/7, which matters when a seized deadbolt or a break-in leaves you needing a secure door tonight.
  • In business since 1987, with long familiarity with the mid-century Kwikset and Weiser hardware common in Southern California homes.
  • We tell you when rekeying or repair is enough, rather than selling replacement when a cheaper fix will do.
  • Experience with both single homes and multi-unit properties, including worn cylinders on older apartment buildings.
  • The owner, David Shar, leads the work, so there is clear accountability for what is installed on your door.

Lock Replacement across Norwalk

Norwalk's housing tells you what to expect at the door. In neighborhoods like Carmenita, near Carmenita Road, and around the Cerritos College and Studebaker Road area, many homes are original post-war stucco ranches. The entry hardware may be decades old, and a deadbolt that has seized near Cerritos College is a very familiar call. We see these in ZIP 90650 and across the city.

Along Pioneer Blvd, Firestone Blvd and Rosecrans Ave, you find 1960s and 70s stucco dingbat apartment buildings. A landlord there might need every unit rekeyed at tenant turnover, with a few visibly worn Kwikset cylinders swapped out entirely. Aluminum sliding patio doors on original mortise latches are another common weak point we can address. For properties in ZIP 90651 or 90652, we can plan the work so each unit ends up with working, matching hardware.

We also help small businesses, such as a shop in the Norwalk Town Square district that needs after-hours lock work after an employee leaves. Whether you are near the Norwalk Metro C Line Station, the Norwalk/Santa Fe Springs Metrolink Station, or off I-5 or I-605, we come to you. Call (323) 997-8867.

Lock Replacement in Norwalk — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the internal pins so old keys stop working, while keeping the same lock body. Replacement installs new hardware. If your lock is worn, damaged or sticking, replacing it is usually the better choice. Call (323) 997-8867 and we can advise.
My old deadbolt will not turn. Do I need a new one?
Often yes, especially on mid-century tubular deadbolts that have seized with age. Sometimes the lock can be cleaned or the strike plate adjusted. We check first and tell you honestly what makes sense.
Can you replace locks if I am locked out right now?
Yes. We are 24/7 and fully mobile. We open the door first, then replace the lock if it is the cause. Call (323) 997-8867 to get started.
Do you handle apartment buildings in Norwalk?
Yes. We work on multi-unit properties, including older dingbat-style buildings along Pioneer, Firestone and Rosecrans, replacing worn cylinders and rekeying units at tenant turnover.
Can you replace the latch on an aluminum sliding patio door?
Often, yes. Original mortise latches on older sliding doors wear out. We inspect the door and let you know whether a replacement latch or another security option fits.
How much does lock replacement cost?
It depends on the number of locks, the hardware you choose, door condition, and timing. We explain the factors and give you a clear answer before work starts. You can also call (323) 997-8867 to discuss your situation.
Do you have a shop I can visit in Norwalk?
No. We are fully mobile only, with no storefront. We come to your home, building or business anywhere we serve, day or night.
Can you replace commercial locks after an employee leaves?
Yes. We can rekey or replace locks for small businesses, including after-hours work, so a former employee's key no longer opens your door.
