Most people think of key duplication as a quick stop at a hardware counter. In Norwalk, that errand often turns into a hassle: a worn original key that copies badly, a restricted key stamped 'Do Not Duplicate' that a kiosk will refuse, or a tenant turnover with a dozen sets needed by Monday. Crenshaw Lock Company is fully mobile, so the cutting machine comes to your driveway, your apartment courtyard or your shop's back door. There is no storefront to visit.

Norwalk's housing makes copying more interesting than it sounds. A lot of the city is post-war tract housing from the late 1940s and 1950s, and many of those single-story stucco ranch homes still have mid-century Kwikset or Weiser entry sets and aging tubular deadbolts. Decades of use wear the brass key and the pins inside the lock, and a copy of a worn key often inherits the wear. Sometimes the right answer is a clean copy. Sometimes it is a quick look at the cylinder first, so you do not pay to duplicate a key for a lock that is about to fail.

Crenshaw Lock has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on telling customers plainly what they need and what they do not. For key duplication, that means we will tell you when a copy is all you need, when a rekey is smarter, and when a restricted-key system requires authorization we have to verify before we cut anything.

How it works in Norwalk

  1. 1

    Call and describe the keys

    Call (323) 997-8867 any hour. Tell us the type of key you have: a standard house key, an office or commercial key, a mailbox key, or a restricted key. Mention the brand if you can see it on the bow, and how many copies you want. That helps us bring the right blanks.

  2. 2

    We come to you

    Because we are fully mobile, we travel to your Norwalk home, apartment building or business with key-cutting equipment and a range of blanks. You do not have to leave a property unattended or find parking at a counter.

  3. 3

    Inspect the original key and lock

    Before cutting, we look at the original key for wear, bends or rounded cuts, and we test how it turns in the lock. A worn key makes a poor master for copies. If the lock is sticking, as older tubular deadbolts often do, we say so before you pay for copies that will not solve the problem.

  4. 4

    Cut and fit-test each copy

    We cut the copies to match, then test each one in the actual lock rather than handing them over untried. A copy that only almost works is worse than none, so we adjust or recut until it operates smoothly.

  5. 5

    Verify authorization for restricted keys

    Restricted keyways are designed so copies can only be made with proper authorization. If your key falls in that category, we will ask for the documentation or authorization the system requires. This protects you, since it is the point of a restricted system.

  6. 6

    Review options and wrap up

    Once your copies work, we go over where each key belongs and whether a rekey or a cylinder replacement would make sense, especially for rentals or after someone has left a job with a key.

What affects the price

  • The type of key: a basic house key differs from a high-security, restricted or commercial key that needs special blanks or equipment.
  • How many copies you need, since multiple sets or a full apartment building's worth involve more cutting and handling.
  • Condition of the original: a badly worn key may need to be code-cut or the lock rekeyed instead, which changes the scope of the work.
  • The time of day: after-hours, weekend and holiday calls are handled differently than scheduled daytime appointments.
  • Your location and access: travel across the area and the ease of reaching the property can factor into the visit.
  • Authorization requirements: restricted systems may require additional verification or ordering steps before copies can be made.

Why Norwalk chooses us

  • Fully mobile and available 24/7, so duplication can happen at your door rather than at a counter with fixed hours.
  • Serving Los Angeles and Ventura County since 1987, with David Shar as owner and lead technician.
  • We test every copy in the real lock instead of assuming a cut key will work.
  • We give honest advice when a worn original or an aging mid-century deadbolt means a rekey or replacement is smarter than another copy.
  • We respect restricted-key systems and verify authorization instead of cutting anything someone asks for.
  • Familiarity with the older Kwikset, Weiser and mortise hardware common in Norwalk's tract homes and apartment buildings.

Key Duplication across Norwalk

Norwalk's neighborhoods each call for slightly different work. In Carmenita, along the Carmenita Road corridor, many homes are single-story stucco ranch and minimal-traditional houses from the postwar aerospace boom, often with their original entry hardware still in service. Around Cerritos College and the Studebaker Road area, we see the same 1950s tract housing, where a seized deadbolt or a key that no longer turns is a common reason people call. If your key barely turns, a fresh copy will not fix it; the cylinder is usually the problem, and we will say so.

The Norwalk Civic Center and Town Square district has its own needs. Small retailers and offices near Norwalk Town Square often need extra keys for staff or a rekey after an employee leaves, sometimes after closing hours. Along Pioneer Blvd, Firestone Blvd and Rosecrans Ave, 1960s and 1970s stucco apartment buildings are common. Landlords there often need multiple key sets for unit turnover, and worn Kwikset cylinders and aluminum sliding patio doors on original mortise latches may need attention at the same time.

We work throughout Norwalk, including ZIP codes 90650, 90651 and 90652, and are easy to reach from I-5, I-605 and the surrounding streets. Whether you are near the Norwalk Metro C Line Station, the Norwalk/Santa Fe Springs Metrolink Station, or the neighborhoods around Metropolitan State Hospital on Bloomfield Ave, call (323) 997-8867 and we will come to you.

Key Duplication in Norwalk — FAQs

Can you duplicate keys at my Norwalk home or do I have to come to you?
We are fully mobile and have no storefront, so we come to you. Call (323) 997-8867 and we will bring the equipment to your home, apartment or business in Norwalk.
Do you offer key duplication at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7, including nights, weekends and holidays. Call (323) 997-8867 to arrange a visit.
Can you copy a key marked 'Do Not Duplicate'?
That marking is not always a true restriction, but genuinely restricted keyways require authorization. We verify the proper authorization before cutting, which protects your property. If you are unsure which type you have, we can look at it.
My old key barely turns in my 1950s deadbolt. Will a copy help?
Usually not. A worn key or a seized tubular deadbolt is common in older Norwalk tract homes. A copy of a worn key carries the wear forward, so we may recommend replacing or rekeying the cylinder instead.
I manage apartments off Pioneer Blvd. Can you handle many keys at once?
Yes. We can cut multiple sets on location and, if turnover is involved, rekey units so old keys stop working. We can also point out worn cylinders that need replacement.
Can you make mailbox keys?
Yes, we cut mailbox keys on location. Mention the type of mailbox if you know it, and whether it is a private or shared system, so we bring suitable blanks.
Is duplicating a key enough after an employee leaves?
Not always. A duplicated key does nothing to stop the copies already out there. For a business near Norwalk Town Square, a rekey is often the better fix. Call (323) 997-8867 to talk through the options.
How is the cost of key duplication determined?
It depends on the key type, how many copies, the original's condition, timing, location and any authorization needs for restricted keys. We explain what applies to your situation before starting the work.
