Carson grew up fast in the late 1960s and 1970s, and a lot of its locks grew up with it. Walk through Scottsdale or Carriage Crest and you will find ranch and split-level stucco homes still fitted with the original key-in-knob sets and single-cylinder deadbolts. After decades of daily use, those locks stick, spin loose, refuse to retract the latch, or finally seize on the one day you need them. Replacing them is often smarter than patching them.

Lock replacement is different from rekeying. Rekeying changes the pins inside a lock you already own so old keys stop working. Replacement removes the whole mechanism and installs new hardware. That makes sense when a lock is worn out, damaged after a break-in attempt, cosmetically tired, or simply too low-grade for the door it protects. We help you decide which path fits, and we will tell you honestly if a rekey would do the job.

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, with no storefront to visit, and we are available around the clock. We bring the work to your door in Carson, whether that is a tract home, a garden apartment off Avalon Boulevard, a manufactured home in a park, or a warehouse near Alameda Street.

How it works in Carson

  1. 1

    Tell us about the door and the problem

    Call (323) 997-8867 and describe what is going on: a knob that spins freely, a deadbolt that jams, a key that snapped, or a lock you simply want upgraded. Details about the door type and age help us bring the right hardware.

  2. 2

    On-site inspection

    At your property we look at the lock, the strike plate, the door edge and the frame. In older Carson homes, the weak point is often the strike or the thin original latch rather than the lock alone, and we point that out before any work starts.

  3. 3

    Choose the hardware and confirm the scope

    We go over options for your door: standard grade or heavier-duty deadbolts, keyed-alike sets so one key runs every exterior door, or specialty locks for sliding patio doors and mobile-home entries. You approve the scope before we begin.

  4. 4

    Remove the old lock and install the new one

    We take out the worn hardware, check the bore and latch alignment, and install the new lock so it throws smoothly and seats fully in the strike. If the door has been damaged, we address fit problems so the new lock works the way it should.

  5. 5

    Test, key handoff and cleanup

    We cycle every lock several times with the door open and closed, confirm each key works, and hand over your keys. Old hardware is removed on request, and we leave the work area clean.

What affects the price

  • The type of lock: a basic knob set, a deadbolt, a mortise lock, a sliding-door latch, or a commercial cylinder each involve different hardware and labor.
  • The number of doors: replacing one lock is a different job than outfitting every exterior door, and keyed-alike sets change how hardware is selected.
  • Hardware grade and finish: heavier-duty security hardware and certain finishes cost more than entry-level sets.
  • Door and frame condition: if the bore is damaged, the strike is loose or the frame is split, extra repair work may be needed for the new lock to perform.
  • Time of service: a late-night or holiday call involves different scheduling than a daytime appointment.
  • Special requirements: park-gate transponders, broken-key extraction or commercial roll-up-door hardware add steps beyond a standard swap.

Why Carson chooses us

  • Fully mobile and available 24/7, so a seized lock at night is handled where you are, with no shop trip.
  • Operating since 1987, with David Shar as owner and lead technician, so older hardware in 1960s and 1970s Carson homes is familiar territory.
  • We tell you when a rekey is enough and when replacement is truly warranted, instead of defaulting to the bigger job.
  • Experience across residential, mobile-home and commercial doors, from Kwikset and Schlage knobs to mortise-style mobile-home locks and roll-up-door cylinders.
  • We can pair a replacement with a rekey of your other exterior doors so one key covers the whole home.
  • Pricing is explained by the factors involved and agreed with you before work begins.

Lock Replacement across Carson

Carson's housing mix shapes what we see. In Scottsdale and Carriage Crest, the tract homes from the late 1960s and 1970s often still carry their original knob locks and single-cylinder deadbolts. A typical call is a worn Kwikset knob that finally seizes and locks someone out, followed by replacing it and rekeying the rest of the exterior doors. Aluminum sliding patio doors with tired latches are another frequent upgrade across ZIP codes 90745 and 90746.

Near Dominguez Hills and the area around California State University, Dominguez Hills, we see rental homes and apartments where locks need replacing between tenants. Along Avalon Boulevard and Carson Street, mid-century garden apartments often have aging hardware that deserves an upgrade. Carson also has a large number of manufactured-home parks, where lightweight doors use mortise-style locks and park gates may rely on transponders that need reprogramming. In Victoria and other master-planned neighborhoods, we handle modern deadbolt and entry-set replacements.

The industrial side of Carson matters too. Warehouses near Alameda Street and the Dominguez industrial zone need commercial cylinders and roll-up-door hardware replaced, sometimes after a break-in attempt or a broken-off key. Whether you are in 90747 near the I-405, 90810 close to the Harbor Freeway, or anywhere between Dignity Health Sports Park and SouthBay Pavilion, we come to you. Call (323) 997-8867.

Lock Replacement in Carson — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the internal pins so old keys no longer work, while keeping the same lock. Replacement installs new hardware. If your Carson lock is worn, damaged or outdated, replacement is usually better. Call (323) 997-8867 and we will tell you which fits.
Are the original locks in my 1970s Carson home worth replacing?
Often yes. Original key-in-knob sets and single-cylinder deadbolts have decades of wear and may be low-grade by today's standards. If they still work smoothly, a rekey may be enough, but we will look at the lock and strike and give you an honest view.
Can you replace the lock on a mobile or manufactured home?
Yes. Many Carson park homes use mortise-style locks on lightweight doors, and we can replace them. If your park gate uses a transponder, we can also help with reprogramming where applicable. Call (323) 997-8867 to describe your setup.
Can I get all my exterior doors keyed alike?
Yes. We can install new locks keyed alike so one key operates every exterior door, or rekey existing locks to match. It is a popular choice after a lockout or when moving into a Carson home.
Do you replace locks on sliding patio doors?
We do. Aluminum sliding doors in many Carson homes develop worn latches that no longer hold securely. We can replace the latch or add a secondary lock suited to your door.
Do you handle commercial lock replacement near Alameda Street?
Yes. We replace commercial cylinders and roll-up-door padlocks and hardware, and we can extract broken-off keys. This is common after a break-in attempt. Call (323) 997-8867 any hour.
Do I need to visit a shop to pick up new locks?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your Carson address with hardware options and install on the spot.
What if my lock failed and I am locked out right now?
Call (323) 997-8867 at any hour. We work 24/7 and can get you back inside, then replace or rekey the lock so the problem does not repeat.
