Norwalk is full of doors that were hung long before anyone imagined unlocking them with a phone. Across the post-war tract neighborhoods, many single-story stucco ranch homes still carry mid-century Kwikset or Weiser entry sets and aging tubular deadbolts. Upgrading to a keypad or smart lock is very doable on these doors, but it goes better when someone checks the bore, the latch, the strike and the door edge first instead of just handing you a box.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has seen how all kinds of locks age, from worn cylinders to deadbolts that no longer turn. We are fully mobile. There is no storefront to visit; we bring the tools and the know-how to your door in Norwalk, at any hour of the day or night.

Smart lock installation is more than drilling and screwing. It means choosing hardware that suits your door and your household, mounting it so the bolt throws smoothly, setting up codes or app access, and making sure you understand how to recover if a battery dies or a phone is lost. If a lock you already own is misbehaving, we also troubleshoot and set up existing smart, keyless and keypad hardware.

How it works in Norwalk

  1. 1

    Talk through what you need

    Call (323) 997-8867 and tell us about the door: entry door, garage side door, apartment unit or business. Let us know whether you want a keypad, app control, or both, and if you already have a lock to install.

  2. 2

    Inspect the door and existing hardware

    On arrival we look at the door thickness, bore holes, backset, latch and strike plate. Older Norwalk doors with tired tubular deadbolts or misaligned strikes often need small corrections before a new lock will work reliably.

  3. 3

    Remove the old lock and prepare the door

    We take out the old deadbolt or knob set and fit the door for the new lock. If the old cylinder has seized, we deal with that carefully so the door and frame are not damaged more than necessary.

  4. 4

    Install and align the new lock

    We mount the lock, check that the bolt extends fully into the strike without binding, and adjust alignment. A smart lock that has to fight a sticking bolt will drain batteries and fail early.

  5. 5

    Set up codes, access and settings

    We program user codes, pair the lock with an app if you are using one, and set options such as auto-lock. You keep the codes, and we point out where the manual override and battery access are.

  6. 6

    Walk-through and troubleshooting

    Before we leave, we test the lock from both sides with you, and review what to do when batteries run low. If a lock you installed yourself is acting up, we can diagnose it on the spot.

What affects the price

  • The lock itself: basic keypad deadbolts, smart locks with app control and models that work with other smart home systems all differ in hardware cost.
  • Door condition: a worn bore, a misaligned strike or a warped door may need extra adjustment before the lock will operate smoothly.
  • Number of doors: a single home entry is different from an apartment building or retail space where multiple locks are installed or coordinated.
  • Removing an old or seized lock: stuck mid-century deadbolts can take more time to remove cleanly than a lock in good condition.
  • Setup complexity: programming several user codes, connecting to apps or hubs and configuring schedules adds to the visit.
  • Time of service: after-hours or emergency calls are handled differently than scheduled daytime installs, and we will explain this when you call.

Why Norwalk chooses us

  • Fully mobile service: we work at your door in Norwalk, with no shop trip and no need to remove the door.
  • Since 1987: decades of experience with mechanical locks means we understand what is underneath the smart hardware, including old Kwikset and Weiser sets.
  • Owner-led: David Shar is the owner and lead technician, so the people who set standards are the ones doing the work.
  • Door-first approach: we check the fit and function of the door before committing to hardware so electronics are not undermined by a binding bolt.
  • Available 24/7: if a seized deadbolt or a departing tenant or employee makes a lock change urgent, you can call any time.
  • Honest guidance: if a simple keypad deadbolt suits your door better than a feature-heavy smart lock, we will say so.

Smart Lock Installation across Norwalk

Norwalk's housing tells you a lot about what a smart lock project involves. In the 1950s tract homes near Cerritos College and the Studebaker Road area, single-story stucco ranch houses often still have their original entry hardware. When one of those deadbolts has seized, we often combine the lockout fix with a new keypad or smart lock, so you are not simply replacing a worn part with another one. In ZIP code 90650, which covers much of the city, this is a very common situation.

Along Pioneer Blvd, Firestone Blvd and Rosecrans Ave, many 1960s and 70s stucco apartment buildings have worn cylinders and aluminum sliding patio doors on their original latches. Landlords turning over units sometimes want keypad entry so they are not rekeying at every move-out. We can discuss which doors suit electronic locks and which, such as sliding patio doors, call for a different security solution. Residents in the Carmenita Road area and in ZIP codes 90651 and 90652 face the same mix of older homes and rental units.

Commercial customers around the Norwalk Civic Center and Norwalk Town Square district may also ask about keypad or smart access for small shops, especially after an employee leaves and codes or keys need to change quickly. Whether you commute via the I-5 or I-605, or use the Norwalk Metro C Line or Metrolink station, our mobile service works around your schedule, including evenings and weekends.

Smart Lock Installation in Norwalk — FAQs

Can you install a smart lock on an older Norwalk home?
Usually yes. Many post-war stucco homes here have standard door preparations that accept modern deadbolts. We check the bore, latch and strike first. Call (323) 997-8867 and describe your door.
What kinds of locks do you install?
We install and set up smart, keyless and keypad locks, and we can troubleshoot locks you already own. We will help you choose a type that fits your door and how you want to use it.
Do I need to bring the lock, or can you supply it?
Either can work. If you have already bought one, we can install it and tell you if the door needs changes. If not, call (323) 997-8867 to talk through suitable options.
My old deadbolt is stuck. Can you still install a smart lock?
Yes. Seized mid-century deadbolts are common in Norwalk tract homes. We deal with the stuck lock first, then fit the new one, often in the same visit.
Can a landlord use keypad locks for apartment turnovers?
Often, yes, on entry doors. This can reduce the need to rekey at every turnover. Sliding patio doors on older buildings may need different hardware, which we can explain on site.
What happens if the batteries die or I lose my phone?
Good smart locks have a backup method, such as a physical key slot or an external power point. We show you how yours works during the walk-through, and we are available 24/7 at (323) 997-8867 if you get stuck.
Can you help set up or fix a smart lock I installed myself?
Yes. We troubleshoot alignment, programming and pairing problems. Sometimes the fix is a small door adjustment rather than new hardware.
Do you have a shop in Norwalk I can visit?
No. We are fully mobile and come to you anywhere in Norwalk, day or night. Reach us at (323) 997-8867.
