Most people think of key duplication as a quick trip to a hardware counter. In Carson, that trip is not always practical. Maybe you work a shift near the refinery zones, you manage a property with several tenants, or you live in a manufactured-home park and need a key that a big-box kiosk cannot cut. Crenshaw Lock Company is fully mobile, so the key machine comes to you instead.

Carson was incorporated in 1968, and much of its housing was built in the late 1960s and 1970s. That means a lot of original Kwikset and Schlage key-in-knob locks and single-cylinder deadbolts that have been copied, and copied from copies, for decades. A copy of a worn copy often binds, sticks or fails altogether. We can work from a key that still turns smoothly, or, when needed, from the lock itself, so your new keys work as they should.

Since 1987, our owner and lead technician, David Shar, has been cutting keys across Greater Los Angeles and Ventura County. We handle standard house keys, office and commercial keys, mailbox keys, and restricted keyways that need extra verification. Because we are available around the clock, you can reach us when a spare is needed urgently, not only during retail hours.

How it works in Carson

  1. 1

    Tell us what you need copied

    Call (323) 997-8867 and describe the key: a front door key, a deadbolt key, a mailbox key, an office key, or something stamped with a restricted or do-not-duplicate marking. Let us know whether it is a home, a mobile-home park unit, or a business so we bring the right blanks and equipment.

  2. 2

    We come to your location

    We are fully mobile, so there is nothing to drive to. We meet you at your home, apartment, park space or business in Carson and set up where it is convenient. We do not make timing promises over the phone that we cannot back up, but we will tell you honestly what to expect when you call.

  3. 3

    Inspect the original key and the lock

    Before cutting, we look at the original key for wear and at the lock it operates. A worn 1970s knob lock or a sticky deadbolt can make even a perfect copy feel bad. If the lock is the real problem, we will tell you plainly and explain your options.

  4. 4

    Verify restricted keys

    Restricted keyways are designed to prevent casual copying. For these, we ask for the proper authorization or proof of authority before duplicating. This protects you, your tenants and your business, and it is not something we skip.

  5. 5

    Cut, deburr and test

    We cut the new keys on location, remove burrs and test each one in the actual lock, not just in the machine. A key should turn smoothly without forcing. If it does not, we adjust or recut it before we leave.

  6. 6

    Label and organize

    For multi-key jobs such as apartments, offices or rental properties, we can help you sort and keep track of which key goes where. We also point out any locks that would benefit from rekeying so lost or unknown copies stop being a worry.

What affects the price

  • The type of key: a basic house key is a simpler job than a high-security, dual-sided or restricted-keyway key.
  • How many copies you need, since multi-key orders for properties or offices involve more cutting and testing.
  • Whether we can copy from a good original or need to create a key from the lock itself because the original is badly worn or missing.
  • The time of day you call, as after-hours and overnight service differs from a standard daytime visit.
  • Whether additional work is needed, such as rekeying, replacing a worn cylinder or servicing a mobile-home lock alongside the duplication.
  • Your location and access, such as a gated mobile-home park or a commercial site that requires coordination.

Why Carson chooses us

  • Fully mobile: we cut keys where you are, which suits Carson's mix of tract homes, park communities and industrial sites.
  • In business since 1987, with David Shar as owner and lead technician, so experience with older Kwikset and Schlage hardware is built in.
  • Every key is tested in your actual lock before we finish, not just checked against a pattern.
  • We are honest when a copy will not fix the problem. If a worn cylinder is causing sticking, we will say so rather than cut key after key.
  • Respect for restricted keys: we verify authorization instead of bypassing the protections built into the system.
  • Available 24/7, so a needed spare is not limited to store hours.

Key Duplication across Carson

Carson's neighborhoods each bring different key needs. In Scottsdale and Carriage Crest, many homes are 1970s stucco ranch and split-level tract houses with original-style key-in-knob locks and single-cylinder deadbolts. Decades of copies of copies mean keys that stick, and we can often cut a cleaner key or point out when the lock itself is tired. Around Victoria and Dominguez Hills, we see a mix of single-family homes, garden apartments and households with shared keys among family members.

Carson also has a notable number of manufactured-home parks, and these have their own needs. Lightweight doors and mortise-style locks are common, and some parks use gate access that works separately from your door key. We can copy door keys on site and discuss lock replacement when needed. A resident in ZIP 90745 or 90746 might need spare keys for a family member, while a landlord near Avalon Blvd or Carson St might need a full set for a garden-apartment unit.

On the commercial side, industrial and warehouse areas off Alameda St and near the I-405, I-110 and SR-91 corridors often need duplicate keys for commercial cylinders, padlocks and roll-up doors. We also serve people working near Dignity Health Sports Park, California State University, Dominguez Hills and the SouthBay Pavilion area, including ZIP 90747 and 90810. Wherever you are in Carson, we come to you.

Key Duplication in Carson — FAQs

Can you duplicate keys at my home in Carson?
Yes. We are fully mobile and cut keys on location at your home, apartment, mobile-home park space or business. There is no storefront to visit. Call (323) 997-8867 to describe what you need.
Do you offer key duplication 24/7?
Yes, we are available 24/7. If you need a spare key late at night or on a weekend, call (323) 997-8867 and we will talk through your situation.
My key is very old and worn. Will a copy work?
Often a copy of a badly worn key will not work well. In older Carson homes with 1970s Kwikset or Schlage locks, we may cut from a better reference, or work from the lock itself. If the lock is worn, we will tell you and discuss options.
Can you copy a key marked Do Not Duplicate?
That marking does not always mean a key cannot be copied legitimately, but restricted keyways require proper authorization. We verify authority before duplicating. If you manage a property or business, have your documentation ready when you call (323) 997-8867.
Do you copy mailbox keys?
Yes, we can cut mailbox keys, including those for apartment and multi-unit mailboxes. Some postal-type locks have specific requirements, so let us know the situation when you call.
I live in a mobile-home park. Can you help with my keys?
Yes. We can copy door keys on site and discuss lock replacement for mortise-style mobile-home locks. Park gate transponders and access devices are separate from your door key, so mention that when you call.
Should I rekey instead of just copying keys?
If you have lost keys, had a break-in attempt, moved into a new place or are unsure who holds copies, rekeying is worth considering. Copying adds more keys to the same system, while rekeying changes which keys work.
Do you handle business and commercial key duplication in Carson?
Yes. We copy office and commercial keys and can work with commercial cylinders and padlocks used on roll-up doors in industrial areas. Call (323) 997-8867 to discuss your site.
