Cerritos is a city where smart locks make sense. Much of it was built out in the 1970s with two-story tract homes and townhome and condo communities, and many of those households have since swapped traditional deadbolts for keypads, fingerprint readers and app-connected locks. Families want to give a teenager a code instead of a key, let a dog walker in on Tuesdays, or stop worrying about a lost key. Smart hardware handles all of that, but only if it is fitted correctly.

The installation is where most of the frustration happens. A smart lock that sits slightly out of alignment will jam, drain its batteries early, or fail to throw the bolt fully. Older doors may have a bore, latch or strike plate that does not match the new hardware. Wi-Fi and app setup, user codes, and auto-lock settings all need to be configured so the lock does what you actually want, not just what the box says.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched keyless entry go from a novelty to an everyday request. We are mobile only, with no storefront to visit. We bring the work to your door in Cerritos, whether it is a single front-door keypad, a whole-house upgrade after buying a home, or smart hardware for a small business.

How it works in Cerritos

  1. 1

    Tell us about your door and goals

    When you call (323) 997-8867, we ask what you want: a keypad, a fingerprint lock, an app-connected deadbolt, or a mix. We also ask about the door type, whether you already own a lock, and who needs access. That helps us arrive prepared.

  2. 2

    Check the door and existing hardware

    On site, we inspect the door's thickness, bore holes, latch, strike plate and frame alignment. A smart lock is only as reliable as the door it is mounted on, so we note any binding, sagging or misalignment before we start.

  3. 3

    Install the lock and fix fit problems

    We remove the old hardware and mount the new lock, adjusting the latch and strike so the bolt extends smoothly and fully. If a door needs minor prep to accept the lock cleanly, we handle it as part of the job.

  4. 4

    Configure codes, users and connectivity

    We set up your master code, add user codes or fingerprints, and connect the lock to its app or your home network if you want remote features. We also set auto-lock and other options to suit your household.

  5. 5

    Test, demonstrate and hand over

    We cycle the lock repeatedly from inside and outside, test every code, and show you how to change settings, replace batteries and use the mechanical key override. You leave knowing how to run it without calling us.

  6. 6

    Rekey or secure the rest of the property if needed

    Many Cerritos homeowners pair a smart lock with a rekey of the other entry points so every door is under one set of keys. We can do that on the same visit.

What affects the price

  • The type of lock chosen, from a basic keypad deadbolt to a fingerprint or app-connected model with more features.
  • The number of doors being converted, since a whole-house upgrade differs from a single front door.
  • The condition of the existing door, bore and frame, and whether any adjustment is needed for a clean fit.
  • Whether you supply your own lock or want us to recommend and source one that suits your door.
  • Extra setup such as network integration, multiple user profiles or pairing with other smart-home systems.
  • Whether you want rekeying or master-key work alongside the install, and the time of day the visit is requested.

Why Cerritos chooses us

  • Fully mobile service, 24/7, so installation happens at your door rather than requiring a trip anywhere.
  • Serving Greater Los Angeles and Ventura County since 1987, with experience across both older hardware and newer electronic locks.
  • Installation includes door and latch alignment checks, which are the most common cause of smart locks jamming or draining batteries.
  • We configure the lock for how you live, then walk you through codes, batteries and the manual key override before we leave.
  • We can combine smart lock installs with rekeying, so a new homeowner can address every entry point in one visit.
  • Plain, honest guidance, including telling you when a simpler keypad suits a door better than a more complex connected lock.

Smart Lock Installation across Cerritos

Cerritos has a distinct mix of housing and commercial property, and smart lock needs vary across it. Around Cerritos Towne Center and the surrounding residential streets in ZIP code 90703, many two-story homes from the 1970s are changing hands. A common request is a full rekey after purchase combined with a keypad or smart deadbolt upgrade, so the new owner starts with fresh credentials and modern convenience.

The Los Cerritos Center district and the Cerritos Auto Square bring a very different set of needs. Retail tenants and managers often want electronic or keypad access for back-of-house and staff doors, and aluminum-storefront and master-keyed hardware calls for care when adding or changing locks. We can advise on what suits a commercial door and what is best left mechanical. Near the Auto Square, we also handle vehicle key and fob situations when someone has lost their only key.

With SR-91, I-605, South Street, Del Amo Boulevard and Bloomfield Avenue running through and around the city, we reach most Cerritos addresses, from residential blocks near the Cerritos Library and Civic Center to offices and retail centers. Call (323) 997-8867 any hour to talk through your install.

Smart Lock Installation in Cerritos — FAQs

Can you install a smart lock on my existing door in Cerritos?
In most cases yes. We check the bore, latch, strike and frame on site and adjust for a proper fit. Call (323) 997-8867 and describe the door, and we can tell you what to expect.
Do I need to buy the lock first?
Not necessarily. You can supply your own, or we can recommend one suited to your door and how you use it. If you already bought one, we will install and configure it.
Will a smart lock still have a physical key?
Many models include a mechanical key override, and we show you how it works. Some fully keyless models do not, so we discuss that before you choose.
Can you set up the app and Wi-Fi connection?
Yes. We configure user codes, app pairing and network connection if you want remote features, then test everything before we leave.
I just bought a 1970s home near Cerritos Towne Center. Should I rekey too?
It is a smart move. You cannot know who holds keys to the old locks, so rekeying the other doors while adding a smart lock gives you a clean start. Call (323) 997-8867 to arrange both.
Do you install keypad locks for businesses?
We can advise on keypad and electronic options for commercial doors, including storefront and master-keyed setups. The right choice depends on the door and the hardware already in place.
What if my smart lock stops working at night?
We are 24/7 and mobile. Dead batteries, misalignment and settings problems are common causes, and we can troubleshoot on site. Call (323) 997-8867.
How is the price determined?
It depends on the lock type, number of doors, door condition, extra setup and any rekeying. We discuss these factors with you when you call so there are no surprises.
