Rekeying changes the inside of a lock so it works with a new key while the old key no longer turns it. You keep the same deadbolts, knobs and handles, but anyone who held a copy of the previous key, whether a prior owner, a former tenant, a contractor or an ex-roommate, is locked out. For most households it is the most sensible first step after buying a home, ending a lease, or losing a set of keys.

Cerritos has a lot of the housing and buildings where rekeying makes sense. The city was incorporated in 1956 as Dairy Valley and renamed in 1967. Much of it was built out in the 1970s with two-story tract homes and townhome and condo communities. Those houses have changed hands over the years, and many hold hardware that has been through several owners. Alongside the neighborhoods sits a big commercial footprint, from Los Cerritos Center to the dealerships at Cerritos Auto Square, where management and tenant changes call for new keying.

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. We work at your door, at any hour, and we do the rekey on site so you leave with working keys the same visit.

How it works in Cerritos

  1. 1

    Call and describe the locks

    Call (323) 997-8867 and tell us what you have: how many exterior doors, whether they are deadbolts, knobs or handlesets, the brands if you know them, and whether any are smart locks or keypads. This helps us bring the right pins, plugs and key blanks.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, we come to your home, condo or business. There is no shop visit and no need to remove hardware and bring it anywhere.

  3. 3

    Inspect each lock

    We check that every cylinder is in good working order. Rekeying only makes sense when the lock is sound. If a deadbolt is worn, loose or damaged, we will tell you honestly and explain whether replacing it is the better choice.

  4. 4

    Rekey the cylinders

    We remove the cylinder, replace the internal pins to match a new key, and reassemble. We can key several doors alike so you carry one key for the front door, side door and garage entry.

  5. 5

    Test and hand over keys

    We test every lock with the new key and confirm the old key no longer works. You receive your new keys, and we can cut extras on site for family members or property managers.

  6. 6

    Optional upgrades

    If you want a keypad or smart lock on the front door, we can discuss options while we are there. For businesses, we can also set up master-key structures so management has access across multiple doors.

What affects the price

  • The number of locks or cylinders being rekeyed, since each one is handled individually
  • Whether you want all doors keyed alike or on separate keys
  • The brand and condition of the existing hardware, including whether any cylinder needs replacing instead
  • How many extra keys you need cut
  • Whether the job involves commercial master-key systems, such as a storefront with several doors and levels of access
  • Time of day and urgency, since we work around the clock and after-hours calls are handled differently from scheduled daytime visits

Why Cerritos chooses us

  • Fully mobile: we do the work at your door, so there is no shop trip and no hardware left behind for days
  • In business since 1987, with David Shar as owner and lead technician
  • Available 24/7, useful when you close on a house late in the week or lose keys at night
  • We tell you when a lock should be replaced rather than rekeyed, instead of upselling either option
  • Experience with both residential hardware and commercial storefront and master-keyed systems
  • We can pair a rekey with a keypad or smart-lock upgrade in one visit

Lock Rekeying across Cerritos

In Cerritos, rekeying comes up in a few distinct ways. A buyer picking up a 1970s two-story near Cerritos Towne Center will often want every exterior lock rekeyed on move-in day, and may also want a keypad or smart lock on the front door. Townhome and condo owners have the same concern, since previous owners, tenants and service people may still hold keys. We serve homes throughout ZIP code 90703.

The commercial side is just as real. A retail tenant in the Los Cerritos Center district taking over a space, or a new management team, may need the storefront rekeyed and a master-key system set up so the right people open the right doors. Aluminum-storefront hardware and master-keyed systems are common in the office and retail centers around the city, and we are comfortable working with them.

We reach customers along South St, Del Amo Blvd and Bloomfield Ave, and from drivers coming off SR-91 or I-605. If you are near Cerritos Auto Square and have lost the only key or fob to a vehicle, we can discuss on-site key and fob help as well. Call (323) 997-8867 any time, day or night.

Lock Rekeying in Cerritos — FAQs

What is the difference between rekeying and changing locks?
Rekeying changes the internal pins so a new key works and the old one does not, while keeping the same hardware. Replacing swaps the whole lock. Rekeying is usually the more economical option when the hardware is in good condition.
Should I rekey after buying a home in Cerritos?
Yes, it is a smart first step. You cannot know how many copies of the old keys exist. We can rekey all exterior locks on move-in day. Call (323) 997-8867 to arrange a visit.
Can you make all my doors work with one key?
Yes. We can key the front door, back door, side gate and garage entry alike so you carry a single key, or keep certain doors on separate keys if you prefer.
Can smart locks and keypads be rekeyed?
Many have a physical key cylinder that can be rekeyed, while the electronic code is changed separately. If you want to move to a keypad or smart lock, we can talk through options during the visit.
Do you handle commercial rekeying at retail centers?
Yes. We can rekey storefront locks and set up master-key systems for new tenants or management. Call (323) 997-8867 to describe your doors and the access levels you need.
Do I need to be home during the rekey?
Someone authorized should be present so we can access the locks and hand over the new keys. For a business, a manager or tenant representative can authorize the work.
Are you open at night and on weekends?
Yes, we are available 24/7. We are fully mobile and come to you wherever you are in Cerritos.
What if a lock is too worn to rekey?
We inspect first. If a cylinder is damaged or worn, we will explain that replacement is the better choice and show you the options before doing anything.
