A deadbolt is one of the simplest upgrades you can make to a door, and in Cerritos there are plenty of reasons to do it. Many homes here are upscale two-story tract houses and townhome or condo units built out largely in the 1970s. Original hardware on those doors has often been through decades of use, and some doors were never fitted with a proper bolt at all, or carry a worn one that no longer throws smoothly.

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: there is no storefront to visit. We come to your door with the hardware and tools, check how the door and frame are built, and install a deadbolt that fits both the door and how you live. That might be a single-cylinder bolt with a thumbturn inside, a double-cylinder where a nearby window makes that sensible, or a deadbolt paired with a keypad or smart-lock function.

We work around the clock, so a new deadbolt does not have to wait for business hours. Whether you just closed on a house near Cerritos Towne Center, had a break-in scare, or are simply tired of a sticky old lock, we can help you decide what to install and then do the work on site.

How it works in Cerritos

  1. 1

    Call and describe the door

    Call (323) 997-8867 any hour. Tell us whether the door is wood, metal, or fiberglass, whether it already has a deadbolt, and what prompted the change. This helps us bring suitable hardware to the job.

  2. 2

    Assess the door and frame

    On site, we look at the door edge, the existing bore holes, the strike plate, and the frame. A deadbolt is only as strong as the wood or metal around it, so we check for cracks, loose jambs, or short screws before anything is installed.

  3. 3

    Choose the right type of deadbolt

    We explain the difference between single-cylinder and double-cylinder models, along with keypad or smart-lock options that many Cerritos homeowners now prefer. We also talk through practical concerns such as exit access and glass near the door.

  4. 4

    Install and align

    We fit the deadbolt, drilling or adjusting the door only as needed, and set a reinforced strike plate with longer screws that reach into the framing. The bolt should extend fully and retract without force.

  5. 5

    Test and key setup

    We operate the lock repeatedly with the door open and closed, confirm the keys work smoothly, and can key the new deadbolt to match your other locks where the hardware allows it.

  6. 6

    Walk-through and care tips

    Before leaving, we show you how everything operates, hand over keys or codes, and explain simple upkeep so the lock keeps working well for years.

What affects the price

  • Whether you are adding a brand-new deadbolt or replacing an existing one, since new installs may require drilling and replacements often do not.
  • The type of lock chosen: a standard single-cylinder, a double-cylinder, or an electronic keypad or smart deadbolt.
  • The condition of the door and frame, including whether a strike plate, jamb repair, or reinforcement is needed.
  • The number of doors being done and whether you want them all keyed alike.
  • Door material and any prior boring, such as metal or fiberglass doors with nonstandard preps.
  • Time of service, since after-hours or urgent calls can be handled differently from scheduled work.

Why Cerritos chooses us

  • Fully mobile service: we bring the work to your door in Cerritos rather than asking you to visit a shop, because we do not have a storefront.
  • In business since 1987, with owner David Shar personally leading the work and standards.
  • Available 24/7, so a deadbolt can be installed right after a move, a break-in, or a lost key.
  • We inspect the door and frame first and tell you plainly if reinforcement is needed, instead of just bolting a lock onto a weak spot.
  • Experience with both traditional keyed deadbolts and the keypad and smart-lock hardware common in Cerritos homes.
  • Honest guidance on single versus double cylinder, including the safety tradeoffs of keyed-inside locks.

Deadbolt Installation across Cerritos

Cerritos began as Dairy Valley in 1956, was renamed in 1967, and grew into a master-planned city with most homes built out in the 1970s. Around Cerritos Towne Center, you will find many of those two-story tract homes and townhome communities in ZIP code 90703. After a purchase, owners often want a fresh deadbolt, a rekey, and maybe a keypad upgrade all in one visit, which we can handle at the door.

The city also has a big commercial presence, from the Los Cerritos Center district to Cerritos Auto Square, and the nearby civic area with the Cerritos Center for the Performing Arts, Cerritos Library, and the Sculpture Garden. If you manage a small office or retail space and need a deadbolt on a back or service door, we can fit one that suits the door, whether it is wood or an aluminum storefront frame.

We travel throughout Cerritos using routes like SR-91, I-605, South St, Del Amo Blvd, and Bloomfield Ave. Wherever you are, call (323) 997-8867 and we will talk through what your door needs.

Deadbolt Installation in Cerritos — FAQs

Can you install a deadbolt on a door that does not have one?
Yes. If the door is suitable, we drill the proper bore holes, fit the bolt and strike, and reinforce the frame. Call (323) 997-8867 and describe your door so we can plan.
What is the difference between single- and double-cylinder deadbolts?
A single-cylinder uses a key outside and a thumbturn inside. A double-cylinder needs a key on both sides, which can help when glass is near the door but can slow exit in an emergency. We will help you weigh that.
Do you install keypad or smart deadbolts in Cerritos?
Yes. Many Cerritos homes now use keypads or smart locks, and we can install them on suitable doors. We can also advise whether a standard keyed deadbolt makes more sense for your setup.
Can I get a deadbolt installed at night or on a weekend?
We are available 24/7, including nights, weekends, and holidays. Call (323) 997-8867 and we will discuss your situation.
Will a new deadbolt actually make my door more secure?
It helps a lot, but only if the door and frame are sound. That is why we check the jamb and use a reinforced strike plate with long screws, not just swap the lock.
Can the new deadbolt use the same key as my other locks?
Often yes. Depending on the brand and keyway, we can key the new deadbolt to match your existing locks so you carry fewer keys.
Do you have a shop I can visit in Cerritos?
No. We are a mobile-only locksmith and come to your home or business, so there is no storefront to visit.
I just bought a home near Cerritos Towne Center. Should I add a deadbolt?
It is a smart step. Previous owners may still hold keys, so we can install new deadbolts or rekey existing ones in one visit. Call (323) 997-8867 to get started.
