Getting a spare key made usually means a trip to a hardware store, a line at the counter, and a copy that may not turn smoothly in the lock. We take a different approach. Our locksmith drives to your home, office, or building and cuts the keys right there, where you can test each one in the actual lock before we leave.

Crenshaw Lock Company has served Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. Over those years we have copied everything from basic house keys to office keys, mailbox keys, and keys stamped with restrictions that most walk-in counters will not touch. We are fully mobile, with no storefront, so our attention is on your job.

A good duplicate starts with a good look at the original. Worn keys, bent blanks, and mismatched key types are the most common reasons copies stick or fail. We check the key and the lock together, choose the right blank, and cut with care, so the spare you hold is something you can trust on a busy morning.

How our key duplication service works

  1. 1

    Call and describe the key

    Call (323) 997-8867 and tell us what you need copied: a house key, office key, mailbox key, or a key marked restricted or do not duplicate. Tell us how many copies you want and where you are, and we will arrange a visit.

  2. 2

    We come to you

    Our mobile locksmith travels to your home, workplace, or building with key blanks and cutting equipment. There is no need to leave your property or hand your key to someone at a counter.

  3. 3

    Inspect the original and the lock

    We look at the key's condition and identify the keyway and blank type. If the original is badly worn, we tell you, since copying a worn key can pass the wear along to the new one.

  4. 4

    Cut the copies on location

    We cut the new keys and clean off burrs so they enter and turn smoothly. Restricted keys are handled according to their system's rules, which may require authorization before we can proceed.

  5. 5

    Test every key in the lock

    Each new key is tried in the actual lock, not just compared to the original. If one binds or sticks, we recut or adjust it before you pay for anything that does not work.

  6. 6

    Hand off and advice

    We give you your keys and the original, and talk through simple habits such as marking copies and keeping a spare somewhere safe, so you are not caught out the next time.

What affects the price

  • The type of key: a standard house key is a different job from a high-security, dimple, or restricted key that needs special blanks.
  • How many copies you need, since cutting several at one visit is handled differently from a single spare.
  • Whether the key is restricted and requires authorization or proof of ownership before it can be copied.
  • The condition of the original key; a worn or damaged key may need extra work or a different approach.
  • Your location and the time of the visit, including after-hours or weekend service, since we are mobile and available around the clock.

Why choose us

  • We are fully mobile, so keys are cut at your door and tested in your own lock instead of in a shop.
  • Serving Los Angeles and Ventura County since 1987, with owner and lead technician David Shar behind the work.
  • We handle several key types in one visit: house, office, mailbox, and restricted keys.
  • We tell you plainly when a worn original should not be copied, rather than cutting a duplicate that will not last.
  • Service is available 24/7, which helps when you are locked out of a spare plan or need copies before a move, hire, or tenant change.

Where we work

Our mobile key duplication service covers Greater Los Angeles, and we travel throughout the San Fernando Valley, the San Gabriel Valley, the South Bay and Harbor area, and the Westside. Whether you manage a home in the Valley or an office near the coast, we bring the cutting equipment to you.

We also work across the Gateway Cities, Central and South LA, and parts of Ventura County. Because we have no storefront, there is no shop to visit. Call (323) 997-8867, tell us where you are, and we will confirm that we can reach your address.

Key Duplication — FAQs

Can you copy keys at my home or office?
Yes. We are fully mobile, so we cut house, office, and mailbox keys on location. Call (323) 997-8867 to arrange a visit anywhere in our service area.
Can you copy a key marked Do Not Duplicate?
Often it depends on the key system. Those markings are not always legally binding, but restricted keys may need authorization or the manufacturer's process. Call (323) 997-8867 and we will explain your options.
Can you copy mailbox keys?
Yes, we can cut mailbox keys on site. Some building or postal systems limit who can authorize copies, so we may ask about ownership or management approval.
Do I need to be home?
Someone should be present with the original key, and for restricted keys, a person with authority to approve copying. We test each copy in the lock before finishing.
What if my original key is worn?
We will inspect it first. A worn original can produce a copy that sticks, so we may suggest a different approach, such as working from the lock itself.
Do you offer key duplication at night or on weekends?
Yes, we are available 24/7. Call (323) 997-8867 any time and we will talk through what you need.
How many copies can I get in one visit?
As many as you need. Many customers have several cut at once for family members, employees, or tenants. Tell us the quantity when you call.
Why have a locksmith copy keys instead of a hardware store?
A locksmith can come to you, handle specialty and restricted keys, and test each copy in your actual lock so you know it works before we leave.
