Copying a key sounds like a five-minute errand, but in Arcadia it rarely is. Homes here range from 1950s and 1960s ranch houses in Upper Rancho, Lower Rancho and Highland Oaks to brand-new custom estates, with condos and apartments clustered near Santa Anita and Huntington Drive. Each building type brings different keys, different hardware and different headaches. Crenshaw Lock Company is fully mobile, so we bring the key machines and blanks to your driveway, office suite or lobby instead of asking you to drive anywhere.

Our work covers standard house keys, office and suite keys, mailbox keys, and many restricted or high-security keys. A restricted keyway is designed so that a hardware-store kiosk cannot copy it, which is exactly why people get stuck. We have served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business on handling the keys other places turn away. Where a key is restricted, we will explain what authorization or proof the system requires before we cut anything.

We are available around the clock. Maybe the only spare is with a tenant who is leaving, a contractor needs copies for a job site, or a family member needs access tonight. Call (323) 997-8867 and we will talk through what you have, what you need and what the best approach is. We would rather tell you honestly that a key needs to be originated or replaced than cut something that will not work smoothly.

How it works in Arcadia

  1. 1

    Tell us about the key and the lock

    Call (323) 997-8867 and describe what you need copied: a front-door key, a suite key, a mailbox key, or something stamped with a restricted or do-not-duplicate marking. Brand names on the lock or key help us bring the right blanks.

  2. 2

    We come to your Arcadia location

    Because we are fully mobile and available 24/7, we travel to your home, condo building, office or commercial space. You do not need to leave the property or hand your only key to a stranger at a counter.

  3. 3

    Verify the key and your authority

    We examine the original key, check its condition, and confirm that you are the owner, tenant or authorized person. For restricted keys, we follow the verification the keyway requires. This protects you and your neighbors.

  4. 4

    Cut the copy on location

    We cut the new key from the matching blank right at the site. A worn original can produce a copy that binds, so we match the cut to the key's intended code where possible rather than copying the wear.

  5. 5

    Test it in the actual lock

    We try the new key in the lock it is meant for, several times, in both directions. If it sticks or turns roughly, we adjust it or discuss whether the lock itself needs attention.

  6. 6

    Talk through next steps

    If your old keys have been floating around among past tenants, contractors or ex-roommates, we can discuss rekeying so only the new keys work. Master-key systems for larger properties are also something we can go over.

What affects the price

  • The type of key: a basic house key differs from a high-security, restricted or dual-sided key that needs special blanks and cutting.
  • Quantity: a single spare is a different job from a full set of copies for a family, a crew or an office.
  • Condition of the original key: a badly worn key may call for cutting by code or a more careful approach instead of a straight copy.
  • Restricted keyway requirements: some systems need verification or authorization, which can affect how the job is handled.
  • Time of day and urgency: after-hours and overnight calls are a different situation from a scheduled daytime visit.
  • Travel within our service area and any additional work requested, such as rekeying or master-key planning.

Why Arcadia chooses us

  • Fully mobile: we cut keys at your location, with no storefront and nothing to drop off.
  • In business since 1987, with owner and lead tech David Shar overseeing the work.
  • Available 24/7, useful when a key problem does not happen at convenient hours.
  • Willing to handle restricted and specialty keys, with honest guidance on what verification is required.
  • We test each key in the real lock instead of handing it over untested.
  • Experience across home, condo, mailbox and commercial hardware, so we can suggest rekeying or master-key systems when copies alone are not the right fix.

Key Duplication across Arcadia

Arcadia's housing mix shapes what people ask us for. In Upper Rancho and Highland Oaks, older ranch homes are regularly torn down and replaced with large custom estates. Those builds often involve a full lockset package and a master-key system, which means a lot of keys that need to be copied accurately for owners, family, property managers and household staff. Lower Rancho and Baldwin Stocker have their own mix of established homes where the original keys have usually been duplicated several times over, and each generation of copy tends to be a little less precise.

Closer to Santa Anita and along Huntington Drive, condos and apartments bring different needs: mailbox keys, building and unit keys, and tenants needing copies for a new roommate. Across Peacock Village and the 91006 and 91007 ZIP codes, we hear from residents who simply want a dependable spare before they need it. Out near 91066 and 91077, the same applies to homeowners who would rather not make a trip across town to get a key copied.

For businesses, tenant spaces in strip centers and around Westfield Santa Anita often need office, storefront and back-room keys copied for staff changes. Whether you are near Baldwin Ave, Santa Anita Ave, Rosemead Blvd, the Foothill Freeway or the Arboretum, we come to you. Call (323) 997-8867 any time.

Key Duplication in Arcadia — FAQs

Can you copy a key that says Do Not Duplicate in Arcadia?
Often, yes, but it depends on the key. A stamp alone does not always mean a key is truly restricted. For genuinely restricted keyways, we need to verify your authorization first. Call (323) 997-8867 and describe the key.
Do I need to come to a shop to get a key copied?
No. Crenshaw Lock Company is fully mobile with no storefront. We bring the equipment to your home, condo, office or business in Arcadia.
Can you copy mailbox keys at my condo or apartment?
Yes, we can cut mailbox keys on location. Ownership or tenancy matters, and some postal-style locks have their own rules, so tell us about the lock when you call (323) 997-8867.
Are you available at night or on weekends?
Yes. We are available 24/7, which helps when a lost key or a missing spare cannot wait until normal business hours.
My key is very worn. Will a copy still work?
A copy of a worn key can inherit that wear and bind in the lock. We test every copy in the actual lock and, where possible, cut closer to the original specification so it operates smoothly.
Can you make keys for a new custom home or master-key system?
Yes. Arcadia has a lot of teardown-and-rebuild construction, and we can discuss lockset packages, keying and master-key systems for new builds in areas like Upper Rancho or Highland Oaks.
Should I rekey instead of just copying keys?
If you are unsure who has copies, such as after a move-in, a tenant change or a contractor job, rekeying is worth considering. Copies leave the old keys working, while rekeying makes them stop working.
Can you duplicate commercial or office keys near Westfield Santa Anita?
Yes, we handle office, suite and storefront keys on location. For restricted commercial keys we will confirm authority first. Call (323) 997-8867 to discuss your space.
