Most people think of key duplication as a quick errand at a hardware counter. In Lancaster, where the Antelope Valley spreads across a wide grid of avenues and the nearest stop can be a real drive, that errand eats a surprising amount of time. Our service flips it: we bring the key machines and blanks to you, wherever you are in town, and cut the copies on location.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around being mobile. There is no shop to visit. That matters for duplication because the work often goes hand in hand with other needs: a landlord wants three copies after a tenant moves out, a family wants spare keys for a two-story stucco home, or a business owner needs extra keys for staff at a strip center.

Key duplication sounds simple, but a good copy depends on the right blank, a clean cut and a test in the actual lock. A copy that almost works is a copy that eventually jams or breaks off in the cylinder. We check every duplicate in the lock it was made for, and we tell you plainly when a key cannot or should not be copied, such as certain restricted keyways that require authorization.

How it works in Lancaster

  1. 1

    You call and describe the key

    Call (323) 997-8867 at any hour. Tell us what kind of key it is: a house key, an office key, a mailbox key, a key stamped do not duplicate, or something you are unsure about. A few details help us bring the right blanks.

  2. 2

    We come to your location

    Because we are fully mobile, a technician drives to your home, rental, office or commercial unit anywhere in Lancaster. Nothing needs to be dropped off, and you do not have to leave the property unattended.

  3. 3

    We identify the keyway and blank

    We look at the original key and the lock it belongs to, match the brand and keyway, and choose the correct blank. Builder-grade residential locks, mailbox locks and commercial cylinders each use different stock.

  4. 4

    We cut and finish the copies

    The key is cut on a mobile machine, then deburred so the edges do not catch or shave metal inside your lock. A rough copy wears out a cylinder faster, so finishing matters.

  5. 5

    We test in the real lock

    Every copy is tried in the lock it will be used on. If it sticks, drags or does not turn smoothly, we recut it or flag a worn lock or worn original key that is causing the problem.

  6. 6

    Restricted keys are handled properly

    Restricted or patented keys cannot be freely copied. We explain what authorization or documentation is typically required, so you know your options before any cutting starts.

What affects the price

  • The type of key: a basic house key differs from a high-security, restricted, or specialty key in blank cost and cutting effort.
  • How many copies you need, since a batch for a rental turnover or a business with several staff is handled differently from a single spare.
  • Whether the original key is worn, because a copy of a worn key can carry the same flaws and may call for cutting by code or rekeying instead.
  • Restricted keyway requirements, which can involve authorization steps and special blanks.
  • Time of day and urgency, since we are available around the clock and after-hours visits are a different kind of call than a scheduled one.
  • Whether other work is bundled in, such as rekeying, lock repair or lockbox installation during the same visit.

Why Lancaster chooses us

  • Fully mobile: the machines come to you, so there is no storefront, no drive across the valley and no leaving a property unattended.
  • In business since 1987, with David Shar as owner and lead tech, so the work reflects decades of hands-on lock experience.
  • Available 24/7, which helps landlords, property managers and business owners who cannot wait for store hours.
  • Every copy is tested in the actual lock rather than handed over untried.
  • We tell you when a copy is a bad idea, for example when a worn original or a failing lock would make rekeying the smarter fix.
  • We can combine duplication with rekeying or lock repair in one visit, which suits rental turnover and vacant-property work.

Key Duplication across Lancaster

Lancaster has a mix of housing that makes key duplication a regular need. The suburban tract neighborhoods of West Lancaster and East Lancaster are full of two-story stucco homes from the 1980s through the 2000s, many with builder-grade locks that see years of daily use. Families there often want spare keys for kids, relatives or house sitters, and copies cut from a well-worn key can fail, so we check the original first. In ZIP codes 93534 and 93535, rentals are common, and landlords frequently need several fresh copies after a turnover.

Near The BLVD and the older downtown bungalows and apartment buildings, property managers are often juggling multiple units. We can cut copies and rekey on the same visit so every tenant gets a working set. Homes that entered the market during the foreclosure era, especially vacant tract homes in East Lancaster, may need keys cut alongside lockbox installation or rekeying so new owners or agents have a clean set.

Businesses along Avenue K, Avenue J and Avenue L, and strip centers with aluminum storefront doors, often need extra keys for employees. Sun exposure in the high desert can degrade cylinders over time, which makes a stiff lock hard on new copies. Whether you are in Quartz Hill, near Fox Field, or in ZIP 93536 out toward the edges of town, we come to you. Call (323) 997-8867.

Key Duplication in Lancaster — FAQs

Do you really come to me to copy keys in Lancaster?
Yes. We are fully mobile with no storefront. We drive to your home, rental or business in Lancaster and cut the copies on location. Call (323) 997-8867 to arrange it.
Can you copy a key marked do not duplicate?
Not automatically. That stamp is not always a legal barrier, but we are careful with restricted keys. We will explain what authorization may be needed. Call (323) 997-8867 and describe the key first.
Can you duplicate mailbox keys?
Yes, in many cases. Mailbox locks use their own blanks and keyways, so tell us what the lock looks like when you call (323) 997-8867. Some postal-controlled locks have additional rules.
I manage rentals near The BLVD. Can you cut multiple copies?
Yes. Landlords and property managers often need several copies per unit, and we can pair duplication with rekeying so old tenant keys no longer work.
What if my original key is worn?
A copy of a worn key can inherit its flaws. We test the result in your lock and may suggest cutting by code or rekeying if the original is too far gone.
Are you available outside normal hours?
Yes, we are available 24/7. If you need a key copied late at night or on a weekend, call (323) 997-8867.
Can you copy keys for a business on Avenue K or Avenue L?
Yes. We handle office and commercial keys on site, and can look at worn or sun-damaged cylinders that may be causing trouble with the keys you already have.
How do you price key duplication?
It depends on key type, quantity, restricted keyways, the condition of the original and timing. We do not quote numbers on this page, but we can discuss your situation when you call.
