Most people think of key copying as a quick errand at a hardware counter. In Thousand Oaks, it rarely stays that simple. A Lynn Ranch ranch-style home may have a decades-old brass key that has been copied from copies until it barely turns. A Newbury Park tract home may have several identical keys floating among kids, relatives and a dog walker. A North Ranch estate may use a high-security cylinder that no counter machine can cut. We come to you with the equipment to handle all of it.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so duplication happens on your driveway, in your office suite or at your mailbox cluster. You can watch the key being cut, test it in the lock it is meant for, and fix a sticking cylinder on the spot if the new key reveals a problem.

This page explains how mobile duplication works, what affects the cost, which keys can and cannot be copied, and what to expect across the Conejo Valley. If you are not sure what kind of key you hold, call (323) 997-8867 and describe it. We will tell you honestly whether it can be copied on site.

How it works in Thousand Oaks

  1. 1

    Tell us about the key and the lock

    When you call, describe the key: its shape, any stamping on the bow, the brand of the lock, and how many copies you need. Mention if it is a house key, an office key, a mailbox key or something marked as restricted. That helps us bring the right blanks and equipment.

  2. 2

    We come to your location

    We are mobile and available around the clock, so there is no shop to drive to. We arrive at your home, office or business park with a cutting setup in the vehicle, ready to work wherever the key is needed.

  3. 3

    Inspect the original

    A worn original produces a worn copy. We check the key for damaged cuts, bends and wear, and look at the lock too. If the original is badly worn, we may suggest cutting from the lock's code or decoding the cylinder for a cleaner result.

  4. 4

    Cut and finish the copy

    We select the correct blank, cut it to the original or to code, and deburr the edges so it does not shred pocket linings or catch inside the cylinder. Mailbox keys and standard residential keys are usually straightforward.

  5. 5

    Test in the actual lock

    A copy that looks right can still bind. We try each new key in the real lock several times, including deadbolts and any secondary locks, and adjust it until it turns smoothly.

  6. 6

    Handle restricted keys properly

    Restricted or patent-protected keys, such as many high-security systems, require authorization from the owner or the registered key holder. We will explain what proof is needed before copying and will not skip that step.

What affects the price

  • Key type: a basic house key is a different job than a dual-sided high-security key, a tubular key or a laser-cut key.
  • Restricted keyways: protected systems need authorization and specialty blanks, which affects the work involved.
  • Quantity: several copies in one visit are more efficient than separate trips.
  • Condition of the original: a worn key may require decoding or cutting by code, which takes more time.
  • Time of day: after-hours and holiday visits differ from scheduled daytime appointments.
  • Location and access: travel across the Conejo Valley, and whether we must work through a gate or intercom, can affect the visit.

Why Thousand Oaks chooses us

  • Fully mobile: the work is done at your door, not at a counter, so you can test the key immediately.
  • Experience since 1987 across Los Angeles and Ventura County, including older residential hardware and modern high-security systems.
  • Restricted-key honesty: we explain authorization requirements instead of promising a copy we should not make.
  • Lock diagnosis included: if a new key sticks, we can tell whether the key or the lock is the problem.
  • Capable with estate-level hardware, such as multipoint and high-security cylinders common in North Ranch and Dos Vientos.
  • Available 24/7, with direct contact at (323) 997-8867.

Key Duplication across Thousand Oaks

Thousand Oaks covers a lot of ground and a lot of different locks. In Lynn Ranch and older central Thousand Oaks, many 1960s to 80s ranch and split-level homes still carry original-era hardware, and decades of copying has left some keys worn. In Newbury Park, extensive tract housing means many homes share common lock brands, which makes duplication simple but also makes it worth tracking who holds a copy. Residents near ZIP code 91320 and 91362 often call after a move, when a handful of keys has become many more than anyone remembers handing out.

Up in North Ranch and Dos Vientos Ranch, the picture changes. Higher-end gated and custom estates often have multipoint European-style locks, high-security cylinders and gate or intercom systems. Copies of these keys are typically controlled, so we verify authorization and can also help troubleshoot a gate or intercom that is misbehaving. A hillside custom home in ZIP 91360 or 91361 may also mean a long driveway and several outbuilding locks, all of which we can key together or copy for.

On the business side, Thousand Oaks has large office and biotech parks, plus The Oaks mall, the Civic Arts Plaza and the Amgen campus nearby, which creates steady demand for office key copies, master-key systems and access control. Whether you are along Thousand Oaks Blvd, Moorpark Rd, Hampshire Rd or Borchard Rd, or near US-101 and SR-23, we come to you. We are mobile only, with no storefront, so a call to (323) 997-8867 is the way to start.

Key Duplication in Thousand Oaks — FAQs

Can you copy my key at my home in Thousand Oaks?
Yes. We are fully mobile and cut standard house, office and mailbox keys on location. Call (323) 997-8867, describe your key, and we will confirm what can be done at your door.
Do I have to visit a shop?
No. Crenshaw Lock Company has no storefront. We come to your home, office or business park anywhere we serve in the Conejo Valley.
Can you copy a key stamped Do Not Duplicate?
That stamp is not always legally binding, but we take it seriously. We will ask about ownership and authorization first. For truly restricted systems, only authorized holders can have copies made.
Can high-security keys like Medeco or Mul-T-Lock be copied?
Often yes, but only with proper authorization and the correct blanks. These are common at estates in North Ranch and Dos Vientos. Call (323) 997-8867 so we can discuss your specific system before visiting.
My original key is very worn. Is a copy still possible?
Usually. Copying a worn key reproduces the wear, so we may instead cut by code or decode the lock to produce a cleaner key. We inspect it first and recommend the best approach.
Can you copy mailbox keys?
Yes. We handle mailbox keys for homes and multi-unit properties. If your mailbox is a USPS-controlled lock, we will explain what is and is not something we can do.
Can you set up master keys for an office or biotech suite?
Yes. We work on master-key systems for multi-suite offices and business parks, so different staff can have different access. Call to describe your layout and doors.
Do you offer duplication outside normal hours?
We are available 24/7. Pricing can vary for after-hours visits, so ask when you call (323) 997-8867 and we will explain what affects the cost.
