Most people think of key duplication as a quick stop at a hardware counter. In Cerritos, where daily life revolves around SR-91, I-605 and long drives between home, work and the shops along South St and Del Amo Blvd, a trip just to copy a key is a chore. Crenshaw Lock Company is fully mobile, so we bring the cutting equipment to your driveway, your office suite or your storefront. There is no shop to visit; the work happens where you are.

Our owner and lead technician, David Shar, has been in the trade since 1987, and that experience matters for duplication more than people expect. A good copy depends on reading the original key correctly, choosing the right blank and testing the result in the actual lock. A worn original can produce a copy that sticks or fails, so we check the cylinder as well as the key. If the lock itself is the problem, we say so plainly instead of cutting copies that will not work.

We handle standard house keys, office and master-keyed commercial keys, mailbox keys, and many restricted or controlled keyways. Restricted keys are a special case because they are designed not to be copied casually, so we talk through authorization and what the system allows before we promise anything. We are available around the clock, so a copy does not have to wait for business hours.

How it works in Cerritos

  1. 1

    Tell us what needs copying

    Call (323) 997-8867 and describe the key: house, office, mailbox, or something stamped as restricted. Tell us where you are in Cerritos and how many copies you want. We will explain what we can do on site and what we may need to confirm first.

  2. 2

    We come to your location

    Because we are fully mobile, a technician drives to your home, office or retail space with cutting equipment and a range of blanks. Whether you are in a townhome community or an office center, the work is done at your door.

  3. 3

    Inspect the original and the lock

    Before cutting, we look at the original key for wear and check that it operates the lock smoothly. A badly worn original makes a poor template, and a sticky lock can make a good copy feel bad. Catching this first saves you frustration later.

  4. 4

    Cut and match the blank

    We select the correct blank for the keyway and cut the copy to the original's pattern. For restricted or controlled keyways, we verify authorization and the rules of that system before proceeding.

  5. 5

    Test in the actual lock

    Every copy is tried in the lock it is meant for, several times, to confirm it turns cleanly without forcing. If a copy binds, we adjust or recut it rather than hand it over and hope.

  6. 6

    Review spares and next steps

    We help you decide who should hold which key. If a key has been lost, we may suggest rekeying instead of duplicating, since copies of a missing key do not restore security.

What affects the price

  • The type of key: a basic house key is a different job from a high-security, restricted or dimple key.
  • How many copies you need, and whether they are cut in one visit.
  • Whether the key is a standard blank or a controlled keyway that requires authorization and special blanks.
  • The condition of the original key, since worn keys may need extra work or a code-based cut instead.
  • Whether you need duplication only or also rekeying, lock repair or a hardware upgrade at the same visit.
  • Your location and the time of day, since we serve customers 24/7 across the area.

Key Duplication across Cerritos

Cerritos is a master-planned city, incorporated in 1956 as Dairy Valley and renamed in 1967, and much of it was built out in the 1970s. Upscale two-story tract homes and townhome and condo communities fill the neighborhoods around Cerritos Towne Center, and many have since added keypads and smart locks beside traditional deadbolts. That mix means we often copy a mechanical key for the front door while also helping a family sort out who has access codes and who has physical keys. If you recently bought a home near Cerritos Towne Center, copies are a good time to ask whether a rekey makes sense, since you cannot know who holds the previous owner's keys.

The city also has a large commercial footprint. The Los Cerritos Center district is full of retail tenants, where new management or staff turnover often means extra keys for storefront doors and back rooms, sometimes on a master-key system. Over at Cerritos Auto Square, dealership and service staff deal with a lot of keys and fobs, and we can help with duplicate keys for the building hardware that surrounds them. Many of these doors use aluminum-storefront hardware, which has its own cylinders and keyways we are familiar with.

We serve addresses throughout ZIP code 90703, from the streets near the Cerritos Library and the Civic Center's Sculpture Garden to residences and offices near the Cerritos Center for the Performing Arts, along Bloomfield Ave, South St and Del Amo Blvd. Call (323) 997-8867 any time and we will come to you.

Key Duplication in Cerritos — FAQs

Do I have to bring my key to a shop in Cerritos?
No. Crenshaw Lock Company is fully mobile with no storefront, so we come to your home, office or business in Cerritos. Call (323) 997-8867 to arrange a visit.
Can you copy a key marked 'Do Not Duplicate'?
That stamp is often just a marking and does not always prevent copying, but we will not cut keys for a system where copying is restricted without proper authorization. We will explain what is possible for your specific key.
Can you duplicate restricted or high-security keys?
In many cases yes, with verification of authorization and the correct blank. Some systems require the original owner or a registered account. Call (323) 997-8867 and describe the key so we can tell you what to expect.
Do you copy mailbox keys?
Yes. We can cut copies of mailbox keys for homes, townhome communities and office buildings, provided the mailbox is yours or you have the right to authorize the copy.
Can you copy office and master-keyed commercial keys?
We work with commercial keys, including master-keyed systems used by retail and office tenants. We will confirm you are authorized to have copies, since master keys control access to multiple doors.
Should I copy a key or rekey the lock?
If you still have a working key and just want spares, duplication is fine. If a key was lost, stolen or came with a newly purchased home, rekeying is usually the better choice, because copies do not remove access from whoever has the missing key.
Do you offer key duplication at night or on weekends?
Yes, we are available 24/7. Call (323) 997-8867 at any hour and we will talk through your situation.
Will the copy work with my smart lock or keypad?
Keypads and smart locks usually still have a mechanical keyway as backup, and we can copy that key. Access codes and app credentials are set up separately, and we can advise on both.
