Most people think of key duplication as a quick stop at a hardware counter. In Simi Valley, where commutes run along the SR-118 and the 23 and many households have several drivers, tenants and teenagers, that errand is easy to put off until the day you are down to one key. We bring the key machine to you. Our technician cuts copies at your door, whether you are in a tract home off Madera Rd or a business park near Easy St, and tests each one in your own lock before leaving.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades working with the hardware that fills Simi Valley's housing stock. We are fully mobile, so there is no storefront to visit. We are also on call around the clock, which matters when a spare is needed on a weekend, late at night, or the moment a tenant moves out.

A good copy depends on more than a blank and a cutter. Worn originals produce worn copies, restricted keyways cannot be duplicated by just anyone, and mailbox keys follow their own rules. Part of our job is telling you honestly what can be copied, what should be replaced or rekeyed instead, and what authorization a restricted key requires.

How it works in Simi Valley

  1. 1

    Call and describe the key

    Call (323) 997-8867 and tell us what you need copied: a front door key, a deadbolt key, an office key, a mailbox key or something stamped with a restricted keyway. Details such as the brand, any markings on the key and the number of copies help us bring the right blanks.

  2. 2

    We come to your location

    Because we are fully mobile, the key machine travels with us. We meet you at your home, business or another agreed spot in Simi Valley. Nobody has to leave work or leave the property unattended.

  3. 3

    Inspect the original key

    Before cutting, we look at the original for wear, bends, cracks and a worn keyway fit. A badly worn key can produce a copy that sticks or fails in the lock. If that is the case, we will tell you and may suggest cutting from the lock's code or rekeying instead.

  4. 4

    Cut and finish the copies

    We match the correct blank to your keyway, cut the copy and deburr it so it slides in smoothly without shedding brass shavings into the lock. For restricted keys, we confirm the authorization the system requires before duplicating.

  5. 5

    Test in the actual lock

    Every copy is tried in the lock it is meant for, both turning and withdrawing, and across a few cycles. A key that merely looks right is not enough, so we check that it operates smoothly on the real door.

  6. 6

    Advice on what comes next

    If you are copying keys after a move-out, a lost key or a contractor visit, we can explain whether a rekey makes sense. Copies are only as secure as the list of people holding keys, and we will help you decide whether that list needs resetting.

What affects the price

  • The type of key: a standard residential key, a high-security or restricted key, a mailbox key or a commercial key each involve different blanks and different effort.
  • The number of copies requested, since cutting several at once is handled differently than a single spare.
  • The condition of the original key, because a worn original may need extra work or a different approach such as cutting by code.
  • Whether the key is restricted and requires authorization or proof of entitlement before it can be duplicated.
  • The time and place of the visit, including after-hours or weekend service and the location within Ventura County.
  • Whether you also want related work done on the same visit, such as a rekey or a repair of a sticking lock.

Why Simi Valley chooses us

  • Fully mobile service: we cut keys on site, so you do not have to find a shop, drive across town or leave a property unattended.
  • Available 24/7, so a spare key does not have to wait for business hours, which suits shift workers, landlords and property managers.
  • Serving Greater Los Angeles and Ventura County since 1987, with hands-on familiarity with the Kwikset, Schlage and similar hardware common in Simi Valley's tract homes.
  • Honest evaluation of worn keys: if a copy is likely to fail, we say so instead of cutting something that looks right but will not work reliably.
  • Every copy is tested in your actual lock before we leave, not just compared against the original.
  • Clear handling of restricted keys, which are only duplicated when proper authorization is in place.

Key Duplication across Simi Valley

Simi Valley's housing is a patchwork, and that shapes what key duplication looks like here. In the Texas Tract and on many streets in ZIP 93065, 1970s ranch homes often still run original or worn Kwikset and Schlage hardware, where keys have been copied from copies for years. Those tired keys are the ones most likely to stick or break off, so we often recommend cutting fresh from a clean original or considering a rekey. In Santa Susana Knolls, older rustic and cabin-style homes on winding lanes may have mixed or older locks that call for careful key matching.

Wood Ranch and Big Sky tell a different story. These newer developments, many gated or semi-gated, typically use modern deadbolts and HOA-standardized hardware, and smart locks are increasingly common. Duplicating a key there can mean confirming which keyway the community uses and whether a smart lock's physical key backup is the one you need copied. Bridle Path homeowners and others around ZIP 93063 and 93062 may need extra keys for family members, guest houses or outbuildings, and we handle those on site.

Businesses get the same mobile service. Shops along Cochran St and First St, offices in the business parks near Easy St and Madera Rd, and tenants of the Simi Valley Town Center often need extra keys for new employees or a mailbox or storefront lock. Whether you work near the Ronald Reagan Presidential Library, run a unit off Tapo Canyon Rd or live in ZIP 93094, call (323) 997-8867 any hour and we will come to you.

Key Duplication in Simi Valley — FAQs

Can you duplicate keys at my home in Simi Valley?
Yes. We are fully mobile, so we bring the key-cutting equipment to your home, office or another location in Simi Valley. Call (323) 997-8867 to arrange it. There is no storefront to visit.
Are you available for key duplication at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7, including nights, weekends and holidays. Call (323) 997-8867 and we will schedule a visit that suits you.
Can you copy a key marked Do Not Duplicate?
A stamp on a key does not always mean it is legally restricted, but we are cautious. For true restricted keyways we require proper authorization before duplicating. Call (323) 997-8867 with the details and we will explain what is needed.
My key is very worn. Will a copy work?
Not always. Copies made from badly worn keys tend to inherit the wear and may stick or fail. We inspect the original first and may suggest cutting by code or rekeying the lock. We will give you an honest recommendation.
Can you duplicate mailbox keys?
Yes, we can cut many mailbox keys on location. Some cluster and community mailboxes are controlled by the postal service or an HOA, so there may be rules about who can request copies. Ask us when you call.
Can you make copies of keys for a gated community like Wood Ranch?
Often yes. We confirm the keyway and any HOA hardware standards first. If your lock is a smart lock, we can copy the physical backup key. Call (323) 997-8867 if you are unsure what you have.
Should I copy keys or rekey after a tenant moves out?
If you cannot be sure how many copies exist, rekeying is usually the better step because it makes old keys useless. You can then have new copies cut for the people who need them. We can do both on one visit.
Do you do office and commercial key duplication?
Yes. We copy office, storefront and other commercial keys for Simi Valley businesses. For master-keyed or restricted systems, we confirm authorization before duplicating anything.
