Most lock replacements in Cerritos start with a simple question: is the hardware still doing its job? A deadbolt that sticks in the cold morning, a key that has to be jiggled, a handle set that has gone loose on a front door, or a lock that has simply outlived its finish are all good reasons to replace rather than keep patching. Sometimes it is also about who might still hold a copy of the key, such as a previous owner, a former tenant, a contractor or an ex-roommate.

Cerritos is a master-planned city that grew out of Dairy Valley and was built out largely in the 1970s, so a lot of the housing is upscale two-story tract homes and townhome or condo communities. Many of those doors have original or mid-life hardware that has seen decades of use, and many owners are now moving toward keypads and smart locks. We handle both sides of that: straightforward like-for-like replacement and modern upgrades that change how you use the door every day.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar. We are fully mobile, so there is no storefront to drive to. We bring the tools and hardware to your door, talk through the options, and install the new locks while you are there. If you are unsure whether you need replacement, rekeying or just a repair, we will tell you honestly, even when the answer is the cheaper one.

How it works in Cerritos

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us what you have: a front door deadbolt, a patio slider, a storefront cylinder, or a garage entry. Let us know whether the lock is failing, was damaged, or you simply want new keys. We are available 24/7, including nights and weekends.

  2. 2

    On-site assessment of the door and hardware

    We come to you and look at the door, the strike plate, the bore holes and the existing lock. We check the door's thickness and alignment, since a lock that binds because the door has shifted may need adjustment as much as replacement. We explain what we find in plain terms.

  3. 3

    Choose the right hardware

    We walk through options that suit the door and how you use it: standard keyed deadbolts, higher-security cylinders, keypads, or smart locks that work with a phone. For townhome and condo communities, we keep in mind any association rules about exterior hardware and finish.

  4. 4

    Remove the old lock and install the new one

    We remove the old hardware and install the new lock, making sure the bolt extends fully and the latch seats correctly. If the strike plate or door prep needs reinforcing or cleaning up, we handle it so the new lock works smoothly, not just looks new.

  5. 5

    Key, test and hand over

    We cut and test keys, or set up keypad codes and smart-lock access, and operate the lock repeatedly from both sides with the door open and closed. You get a quick walkthrough of how everything works, and we can key several locks alike so one key covers your doors.

What affects the price

  • The type of lock chosen: a basic keyed deadbolt, a high-security cylinder, a keypad or a smart lock each sit in very different cost ranges.
  • How many locks are being replaced, and whether they are to be keyed alike so one key works every door.
  • Door condition: extra work such as enlarging a bore, reinforcing the strike area or repairing damage from a forced entry adds labor and materials.
  • Residential versus commercial hardware, since storefront and master-keyed systems use different cylinders and require more planning than a single home door.
  • Whether the work is scheduled in advance or needed urgently at night, on a weekend or on a holiday.
  • Whether rekeying the existing hardware would be enough, which can cost less than full replacement when the locks are in good shape.

Why Cerritos chooses us

  • Fully mobile, so everything happens at your door with no storefront trip and no waiting while a lock is taken away to be worked on.
  • In business since 1987, which means decades of experience with the kinds of hardware found on 1970s-era homes as well as current smart locks.
  • Honest advice on replace versus rekey versus repair, so you only pay for the work the lock really needs.
  • One crew can handle home, storefront and vehicle needs, including key and fob work, so a single call covers a household or a small business.
  • Available 24/7, so a broken lock after a break-in or a failed deadbolt late at night does not have to wait until morning.
  • We test every lock from both sides before leaving and show you how it works, including keypad and smart-lock setup.

Lock Replacement across Cerritos

Cerritos has a distinctive mix of housing and commerce, and lock needs follow it. Around Cerritos Towne Center and the surrounding residential streets in ZIP code 90703, many homes are two-story tract houses from the 1970s. A common job there is a new owner who wants every exterior lock replaced or rekeyed right after closing, often paired with a keypad or smart-lock upgrade on the front door so there are no stray keys floating around from previous years.

The commercial side is just as active. In the Los Cerritos Center district, a retail tenant coming under new management may need storefront cylinders replaced and a fresh master-key system set up so staff access is controlled properly. Aluminum-storefront doors have narrow stiles and specific hardware, so we match the replacement to the frame instead of forcing a residential lock into it.

We also work around Cerritos Auto Square, where a lost key or fob to a vehicle is a different kind of replacement problem and needs on-site programming and cutting. Whether you are near the Cerritos Library, the Civic Center and its Sculpture Garden, or off SR-91, I-605, South St, Del Amo Blvd or Bloomfield Ave, we come to you. Call (323) 997-8867 to get started.

Lock Replacement in Cerritos — FAQs

Should I replace my locks or just rekey them in Cerritos?
If your locks work smoothly and look sound, rekeying is often enough to stop old keys from working. If they are worn, damaged, sticking or outdated, replacement makes more sense. Call (323) 997-8867 and we will look at them and tell you which fits.
I just bought a two-story home near Cerritos Towne Center. What should I do about the locks?
We recommend changing or rekeying all exterior locks so previous owners' keys no longer work. Many buyers also add a keypad or smart lock on the front door at the same time. We can do all of it in one visit at your home.
Can you install smart locks and keypads?
Yes. We install keypad and smart locks on suitable doors and set up codes or phone access with you. We check that the door and strike are aligned first, because even a high-tech lock needs a well-fitted door to work reliably.
Do you replace storefront locks at Los Cerritos Center?
We handle commercial storefront cylinders and master-keying for tenants and managers, including after a change in management. Mall rules and landlord requirements may apply, so check what your lease allows. Call (323) 997-8867 to discuss your setup.
Is there a shop I can visit?
No. Crenshaw Lock Company is fully mobile, so we come to your home, business or vehicle. That means the work is done on site, where we can test the new lock on your actual door.
Can I get lock replacement at night or on a weekend?
Yes. We are available 24/7 for urgent situations such as a broken lock after a break-in or a deadbolt that fails. We do not make arrival-time promises, but you can reach us any hour.
Can all my new locks use the same key?
In most cases, yes. We can key new deadbolts and handle sets alike so one key works your front, back and garage doors. Some specialty or high-security locks may have different keying options, and we will explain them.
What if I lost the only key to my car at Cerritos Auto Square?
We can help with on-site key and fob programming and cutting for many vehicles. Call (323) 997-8867 with the make, model and year, and we will confirm what is possible before starting.
