Most people think of key duplication as a quick errand at a hardware counter. In Sherman Oaks, that errand often runs into a wall. A high-security key stamped with a restricted keyway will not be cut by a self-serve kiosk. A mailbox key may need to be matched by code. An office key marked 'Do Not Duplicate' still has a legitimate owner who needs spares. Crenshaw Lock Company handles all of these by coming to you, with the cutting equipment in the van.

We are fully mobile and available around the clock, and we have served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar. There is no storefront to visit. You tell us where you are, whether that is a flats home off Van Nuys Boulevard, a hillside property south of the Boulevard, or a suite along the Ventura corridor, and we bring the work to your door.

A good duplicate is more than a copy of a copy. Worn keys produce worn duplicates that stick, bind or break off in the lock. Where possible we cut from a clean original or from the lock itself, check that the new key turns smoothly, and tell you honestly if the original is too worn to be a good template. In some cases the better answer is a fresh key made to the lock's code, or a rekey rather than another copy.

How it works in Sherman Oaks

  1. 1

    Tell us what you need copied

    Call (323) 997-8867 and describe the key: house, office, mailbox, padlock, or a restricted or high-security type. Tell us any markings on the bow and how many copies you want, and we will say what can be done on site.

  2. 2

    We come to your location

    Because we are fully mobile, we drive to your home, building or business anywhere in Sherman Oaks. Our availability is 24/7, so urgent needs like a lost spare or a departing employee can be handled outside business hours.

  3. 3

    Inspect the original and the lock

    We check the key for wear, damage and type, and look at the lock it operates. A tired original makes a poor template, so we flag that before cutting anything rather than hand you a key that sticks.

  4. 4

    Verify authorization for restricted keys

    Restricted and high-security keyways exist to control who can make copies. For those, we confirm you are the rightful owner or authorized user before duplicating, which protects you as much as it protects the system.

  5. 5

    Cut and finish the copies

    We cut the new keys on location and deburr them so they do not snag or shed metal into the cylinder. Mailbox, padlock and standard house keys are usually straightforward; complex profiles may take more care.

  6. 6

    Test in the actual lock

    Every duplicate is tried in the lock it is meant for, several times, before we call it done. If a copy binds, we adjust or recut it. You leave with keys that have been proven to work.

What affects the price

  • The type of key: a standard house key is a different job from a restricted, high-security or dimple key that needs specialized blanks and cutting.
  • How many copies you need, since multiple keys cut in one visit are handled more efficiently than separate trips.
  • Whether the original is in good condition or worn enough that we should cut from the lock or by code instead.
  • Whether the blank is common or has to be sourced for a proprietary or patented keyway such as Medeco or Mul-T-Lock.
  • The time of day, since late-night and weekend service differs from a scheduled daytime visit.
  • Your location and access, including hillside properties with gated driveways or winding roads that affect travel and setup.

Why Sherman Oaks chooses us

  • Fully mobile, with cutting equipment in the van, so you never have to leave a property unattended or drive to a shop.
  • In business since 1987, with experience across the pin-tumbler, high-security and commercial hardware common in Sherman Oaks.
  • Comfortable with restricted keyways and high-security cylinders, which many quick-copy counters will not touch.
  • Honest about worn originals: we tell you when a copy will not be reliable and suggest a code-cut key or a rekey instead.
  • Available 24/7, which matters when a lost spare or a staffing change cannot wait until Monday.
  • Every key is test-cycled in the real lock before we leave, not just handed over.

Key Duplication across Sherman Oaks

Sherman Oaks is really two places. On the valley floor, the flats hold 1930s to 1950s Spanish, traditional and ranch homes, along with condos and apartments, and that is where we cut a lot of everyday house, mailbox and garage side-door keys. Neighborhoods like Chandler Estates, with high-value homes and a steady flow of new owners, often call after a purchase because the seller's copies are still floating around. We can duplicate what you need, and if the count of unknown keys worries you, a rekey is a sensible companion service.

South of the Boulevard, the Santa Monica Mountains hillsides rise toward the edge of Fryman Canyon, and the properties there tend toward gated estates and custom homes with higher-security hardware, restricted keyways and driveway keypads or call-boxes. Duplicating those keys takes the right blanks and a confirmation of ownership, and being mobile means we handle it at the property rather than asking you to bring a restricted key somewhere else.

Along the Ventura Boulevard commercial corridor, around the Sherman Oaks Galleria at Ventura and Sepulveda and near Westfield Fashion Square, restaurants, boutiques and offices need spare keys for managers, opening staff and cleaners. We copy storefront and office keys on site, including when a key-holder leaves and you want to rethink who has access. We work throughout ZIP codes 91403 and 91423, with I-405, US-101 and Van Nuys Boulevard all within easy reach. Call (323) 997-8867 any hour.

Key Duplication in Sherman Oaks — FAQs

Can you duplicate a key marked 'Do Not Duplicate' in Sherman Oaks?
Often yes, if you are the legitimate owner or authorized user. That stamp is not legally binding on its own, but we still confirm authorization first. Call (323) 997-8867 and we will explain how we handle it.
Do you come to my home or business, or do I visit a shop?
We are fully mobile and have no storefront. We cut keys on location at your home, office or Ventura Boulevard business anywhere in Sherman Oaks.
Can you copy high-security keys like Medeco or Mul-T-Lock?
Many hillside and high-value homes use these systems. Duplication depends on the specific keyway and its restrictions, and we verify authorization first. Call (323) 997-8867 with the markings on your key and we will tell you what is possible.
What if my original key is badly worn?
A worn original makes a copy that sticks or fails. We will tell you honestly, and may cut from the lock, work by code, or suggest a new key or rekey instead.
Can you make mailbox keys?
Yes. Mailbox keys at flats-area homes and apartment buildings are usually quick to duplicate on site. If a mailbox lock is shared or controlled by the property, we will note that before cutting.
Is key duplication available at night or on weekends?
Yes, we operate 24/7. For an after-hours need, call (323) 997-8867 and we will discuss what you need and how we can help.
Should I duplicate keys or rekey after buying a home in Chandler Estates?
If you just bought, rekeying makes the previous owner's copies useless, and we can then cut fresh duplicates for your household. It is a common combination and one we can often do in a single visit.
What affects the cost of duplication?
Key type, quantity, original condition, blank availability, timing and location all play a part. We do not quote figures on this page, but we can walk through the factors by phone at (323) 997-8867.
