A spare key seems like a small thing until the only one you own is the one in your pocket. In Pomona, where one block can hold a 1900s Craftsman and the next a 1980s tract home, key duplication is rarely one-size-fits-all. The right approach depends on the lock, the key blank, and whether the key is meant to be copied at all.

Crenshaw Lock Company is fully mobile. There is no storefront to drive to and no counter to wait at. We bring the cutting equipment to your home, office, rental property or work site, and we cut and test the copy while you are there. That matters most when the original is worn, when you cannot leave the property, or when you need a batch of keys for several doors.

David Shar founded the company in 1987, and we have been working across Greater Los Angeles and Ventura County ever since. This page explains how mobile duplication works in Pomona, what affects the cost, and what to expect with older hardware, restricted keyways, mailbox keys and commercial locks.

How it works in Pomona

  1. 1

    Tell us about the key and the lock

    When you call (323) 997-8867, we ask what the key opens, such as a front door, a mailbox, an office suite or a padlock. Photos of the key and the lock can help us arrive with the right blanks and tools.

  2. 2

    We come to you

    Because we are mobile and available 24/7, we meet you at your home, apartment, business or work site. You do not need to leave the property or hand your only key to a stranger across a counter.

  3. 3

    Inspect the original and choose the blank

    We check the original for wear, because a copy of a badly worn key will inherit its flaws. We then match the keyway and select the correct blank. If the original is too worn to copy accurately, we may suggest cutting a fresh key to the lock instead.

  4. 4

    Cut and deburr on location

    We cut the copy with mobile equipment and remove burrs so it enters the lock smoothly and does not wear the pins prematurely.

  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, checking the latch, deadbolt or cylinder, and adjust the cut if anything feels rough.

  6. 6

    Restricted and special keys

    Restricted keyways are controlled and typically require authorization. We will explain what we can do, what paperwork may be needed, and when the better path is rekeying or a new cylinder instead of a copy.

What affects the price

  • The key type: a standard house key is a simpler job than a high-security, restricted or specialty key with a controlled blank.
  • The number of keys: cutting several copies for apartment units or an office usually goes more efficiently in a single visit than separate trips.
  • The condition of the original: a worn or damaged key may need to be recut to the lock rather than simply copied, which changes the work involved.
  • Location and time of day: our mobile service runs 24/7, and an after-hours or distant call can be priced differently from a scheduled daytime visit.
  • Authorization requirements: restricted systems may involve verification steps and special blanks that affect the job.
  • Whether other work is needed: if a lock is jammed, failing or needs rekeying before a key can work well, that adds to the scope.

Why Pomona chooses us

  • Fully mobile, so the key is cut at your door and tested in your own lock before we leave.
  • In business since 1987, with long experience across older mortise hardware and modern residential cylinders.
  • Honest about limits: if a key should not be copied, or a worn original calls for rekeying, we say so rather than cutting something that will not work well.
  • Comfortable with batch jobs, such as landlords who need many unit keys cut or rekeyed ahead of move-in dates.
  • Available 24/7 for urgent situations, including seized padlocks and keys that broke off or stopped working.
  • Clear communication about price factors before work begins, with no storefront overhead to explain.

Key Duplication across Pomona

Pomona's housing tells the story of its growth. In the Lincoln Park Historic District, large Queen Anne Victorians and Craftsman homes often still have original mortise locks and older door sets that predate modern deadbolts. Copying a key for hardware like that takes care, and sometimes a mortise lock needs servicing or a period-appropriate rekey instead. Ganesha Hills has period revival homes from the 1920s to 1940s, while Phillips Ranch is mostly 1970s and 1980s tract housing with standard residential cylinders that duplicate quickly.

Near Cal Poly Pomona and Western University of Health Sciences, student rentals and mid-century apartment courts turn over often. A landlord may need keys cut for several units in one visit before new tenants arrive, and we can do that on site in ZIP codes like 91768 and 91767. Downtown Pomona, including the Arts Colony, Antique Row on 2nd Street and the loft conversions in brick buildings, brings its own mix of commercial keys, storefront locks and mailbox keys. The aluminum storefronts along Holt Ave and Garey Ave are another common call.

We also work around Fairplex, where vendors setting up for the LA County Fair sometimes face a seized padlock on a storage container and need on-site cutting and replacement. Whether you are in Westmont, in 91766 or 91769, or close to I-10, SR-60, SR-57 or SR-71, we come to you. Call (323) 997-8867 any hour.

Key Duplication in Pomona — FAQs

Do I have to bring my key to a shop in Pomona?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home, business or work site, cut the copy there and test it. Call (323) 997-8867 to arrange a visit.
Can you duplicate keys for an old Victorian or Craftsman home in Lincoln Park?
Often yes, though it depends on the hardware. Older homes may have original mortise locks or skeleton-key sets. We inspect the lock first and may recommend servicing or a period-appropriate rekey rather than a simple copy.
Can you cut keys for several apartment units near Cal Poly Pomona?
Yes. Landlords with student rentals near the campuses often need several units cut or rekeyed before move-ins. Doing it in one mobile visit is usually efficient. Call (323) 997-8867 to discuss your units.
Can you copy a key marked Do Not Duplicate?
That marking is not always a legal barrier, but restricted keyways are different and typically require authorization. We will explain what is possible for your key and whether rekeying is a better option.
Do you duplicate mailbox keys?
Yes, we can cut mailbox keys on location. Bring the lock details or a photo of the key, and we will match the blank. Some cluster boxes are managed by the property or postal service, so we will let you know if that applies.
What if my original key is badly worn?
A copy of a worn key inherits its wear and may not turn smoothly. In that case we may recut a new key to the lock itself, or suggest rekeying if the lock is also failing.
Can you help with a seized padlock on a storage container?
Yes. If a padlock seizes, for example during LA County Fair setup at Fairplex, we can cut it off on site and fit a replacement with new keys. We are available 24/7 at (323) 997-8867.
How is the price of key duplication determined?
It depends on key type, how many keys you need, the condition of the original, time of day, location and any authorization or lock repair required. We explain these factors before work begins.
