Most people think of key duplication as a quick errand to a hardware counter. In Whittier, the keys in your pocket are often less simple than that. A Craftsman bungalow near Uptown may still use an original mortise lock. A mid-century home in East Whittier may have a mix of builder-grade and upgraded hardware. A hillside property in Friendly Hills may have gate, garage and entry keys that all need copying. Crenshaw Lock Company brings the cutting equipment to you, so the copy is made where you can test it right away.

We have served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are fully mobile, so there is no shop to drive to. That helps most when the key is hard to replace: a restricted keyway, an older key with worn cuts, a commercial key for a storefront, or a mailbox key you have not touched in years.

A good copy depends on the original and on the lock it has to work in. Part of our job is telling you honestly when a duplicate is the right answer and when a worn key or tired lock suggests another path, such as rekeying, repair or a new cylinder. You get a copy that works smoothly, not one that merely resembles the original.

How it works in Whittier

  1. 1

    Tell us about the key

    Call (323) 997-8867 and describe what you need copied: a front door key, an office key, a mailbox key, or a key stamped with a restriction. Tell us where you are in Whittier and how many copies you want so we arrive prepared.

  2. 2

    We come to you

    Our technician drives to your home, business or building. Because we are mobile and available 24/7, the work happens at your door instead of across town, which is handy when you cannot leave a property unattended.

  3. 3

    Inspect the original and the lock

    Before cutting, we look at the key's condition and the lock it operates. A worn or bent original can produce a poor copy, and an older lock may need attention. We explain what we see before proceeding.

  4. 4

    Cut and finish the copies

    We cut the new keys on location and deburr them so they slide in cleanly. Restricted keys follow the rules for that keyway, which may include authorization from the registered owner.

  5. 5

    Test in the actual lock

    We try every copy in the lock it was made for, checking that it turns smoothly and retracts the bolt fully. If a copy binds, we correct it on the spot.

  6. 6

    Talk through next steps

    If the lock is worn, or you suspect old copies are still floating around, we can discuss rekeying so previous keys stop working. That is only a suggestion, never a requirement.

What affects the price

  • The type of key: a standard house key differs from a high-security, restricted or commercial key in the blanks and cutting time involved.
  • How many copies you need, since a single spare and a full set for a household or staff are different jobs.
  • Whether the original key is in good shape or needs extra work to produce an accurate copy.
  • Restricted keyways that require owner authorization or specialized blanks, which affects both process and materials.
  • Your location and the time of day, as an after-hours or late-night call differs from a scheduled daytime visit.
  • Whether you also want related work, such as a lock repair or rekey, added to the visit.

Why Whittier chooses us

  • Fully mobile service: we bring the key cutting to your Whittier address, and there is no storefront to visit.
  • Available 24/7, so a lost-key situation on a weekend or late evening does not have to wait.
  • Experience since 1987 with older hardware, including the original mortise locks found in 1920s Whittier homes.
  • Honest advice on whether a copy, a repair or a rekey is the better fit, instead of selling work you do not need.
  • Every copy is tested in your actual lock before we leave, so you know it works.
  • Comfortable handling both residential keys and commercial or restricted keys for shops and offices.

Key Duplication across Whittier

Whittier has a wider mix of buildings than most cities, and that shapes key work here. Around Uptown Whittier and the historic district, brick and Mission or Spanish Revival storefronts sit near Craftsman bungalows and 1920s-30s Spanish Colonial homes. Many of those homes still carry original mortise locks, and some interior doors use skeleton or bit-style keys. Copying those takes care, and sometimes the better choice is repairing or discreetly retrofitting the lock so it keeps its period look. A boutique on Uptown's main strip may also need extra keys for an aluminum-door cylinder or panic hardware.

In East Whittier, mid-century tract homes tend to have more modern, common keyways, so spare sets for families, renters and caretakers are straightforward. Closer to the Whittier College district, we see shared housing where several people need copies and where old duplicates tend to multiply, which makes rekeying worth considering. Up in Friendly Hills and along Turnbull Canyon, larger gated hillside homes often have separate keys for entry doors, side gates, garages and mailboxes. A newly purchased home there may call for copies after a full rekey, plus possible keypad or smart-lock options on the driveway gate.

We serve Whittier ZIP codes including 90601, 90602, 90603, 90604, 90605, 90606, 90607 and 90608, traveling along routes like Whittier Blvd (SR-72), Beverly Blvd, Painter Ave and Colima Rd. Whether you are near Rose Hills Memorial Park, close to Pio Pico State Historic Park, or just off Painter Ave in 90601, call (323) 997-8867 and we will come to you.

Key Duplication in Whittier — FAQs

Can you duplicate keys at my home in Whittier?
Yes. We are fully mobile, so we cut keys at your home, office or building. There is no storefront. Call (323) 997-8867 to describe what you need.
Do you offer key duplication at night or on weekends?
We are available 24/7, including nights and weekends. Call (323) 997-8867 and we will talk through the situation and get a technician headed your way.
Can you copy the old skeleton or bit keys used in older Whittier homes?
Often, yes, depending on the key and lock. Many 1920s homes near Uptown still have original mortise hardware. We look at the key and lock first and tell you honestly whether copying, repair or another approach makes sense.
Can you copy a key marked Do Not Duplicate?
That marking does not always mean a key is truly restricted. True restricted keyways usually require authorization from the registered owner. Call (323) 997-8867 with the details and we will explain what is possible.
Can you make mailbox keys?
Yes, we can cut mailbox keys on location. Tell us what type of mailbox you have, and we will advise on the options. If the original is lost, a lock change may be the practical route.
Should I duplicate a key or rekey my locks?
A copy is fine if you trust everyone who has had a key. If you just bought a home, for example in Friendly Hills, or old copies are unaccounted for, rekeying stops previous keys from working. We can do either, or both.
Do you handle business keys for shops in Uptown Whittier?
Yes. We can copy commercial keys and also service aluminum-door cylinders and panic hardware common in storefronts. Call (323) 997-8867 to discuss your building.
How do you know the copy will work?
We test each copy in the lock it was made for before we leave. If it sticks or binds, we adjust it right there instead of sending you away with a key that does not work.
