Most people think of key duplication as a quick errand: drive to a hardware store, wait at a counter, and hope the copy works. In Valencia, that errand often means crossing town through McBean Parkway or Valencia Boulevard traffic, only to learn that the key is stamped 'Do Not Duplicate' or that the blank is not on the rack. Crenshaw Lock Company takes the opposite approach. We are fully mobile, so the key machine comes to your home, office or business park, and the copies are cut and tested on the spot.

Valencia is a master-planned community that Newhall Land began developing in 1965, and its housing reflects that. There are HOA tract homes, townhomes and condos in paseo-connected villages, gated neighborhoods, newer developments, and business parks full of tenants who need keys for suites, storage rooms and shared entries. Each of those settings has its own key quirks: builder-grade keyways, mailbox keys that are hard to replace, and commercial keys that come with restrictions.

Our company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on straightforward work. A copy should turn smoothly, retract cleanly, and work in the lock the first time. We check each cut against the lock it is meant for, because a copy that looks right but sticks in the cylinder is not really finished. Whether you need one spare for a house sitter or a full set for a family, we will tell you what is possible and what is not.

How it works in Valencia

  1. 1

    Tell us what you need copied

    Call (323) 997-8867 and describe the key: a house key, office key, mailbox key, or a restricted key with a stamp on the bow. Let us know how many copies you want and where you are in Valencia. Because we are mobile and available 24/7, you can schedule around your day rather than around a store's hours.

  2. 2

    We identify the key and the keyway

    On arrival, we examine your original key and the lock it operates. We identify the brand, the keyway and the blank it needs. Worn originals can produce poor copies, so we look at wear and tell you if the cut is likely to be reliable.

  3. 3

    Check whether the key is restricted

    Some keys are protected by patents, registered key control or a property's own rules. We cannot copy these without proper authorization. If your key is restricted, we explain the options, which may include verifying your authority or working through the lock's key control process.

  4. 4

    Cut the copy on location

    We cut the new key from the correct blank using our mobile equipment, then deburr it so it does not catch or leave metal shavings in your lock. Cutting at your door means we are not guessing about the lock; we have it right in front of us.

  5. 5

    Test it in the real lock

    Every copy is tested in the lock it is meant for, several times, in both directions. We also test it against any deadbolt or secondary lock on the door. If a copy is stiff, we recut it before you pay for it.

  6. 6

    Label, hand off and advise

    We hand over the copies and the original, and can suggest which spare to keep off-site and which to give to a trusted neighbor. If the test revealed a tired lock, we will mention rekeying or replacement as an option, never as a pressure.

What affects the price

  • The type of key: a standard house key is a different job from a high-security, restricted or sidebar-style key, which needs special blanks and equipment.
  • The number of copies requested, since a single spare and a full set for a household or office involve different amounts of work.
  • Whether the original key is worn, bent or damaged, which can mean extra care, a recut or a different approach to get a dependable copy.
  • Blank availability: common keyways are simple, while unusual or commercial blanks may need to be sourced.
  • Restricted-key verification, which can add steps when a property or manufacturer controls who may authorize copies.
  • Time of day and location, since we serve Valencia 24/7 and an after-hours request is handled differently from a scheduled daytime visit.

Why Valencia chooses us

  • Fully mobile: we cut keys at your door in Valencia, so there is no counter, no queue and no storefront to visit.
  • In business since 1987, with owner and lead technician David Shar guiding the work and its standards.
  • Every copy is tested in your actual lock before we leave, instead of being handed over untested at a counter.
  • Honest about restricted keys: we tell you plainly when a key cannot be copied and what the legitimate alternatives are.
  • Familiar with the kinds of locks found across Valencia, from builder-grade tract hardware to commercial keys in business parks.
  • Available 24/7, so a missing spare or a locked-out key situation does not have to wait for store hours.

Key Duplication across Valencia

Valencia's layout shapes how people handle keys. In villages like Northbridge, Bridgeport and Old Orchard, townhomes and condos sit along the paseo system, and keys often serve a front door, a garage entry and a mailbox, sometimes with a shared HOA key on top. In ZIP code 91355, we often see households who want a full set of matching keys so every family member is not passing around one worn original. Cutting copies at the door means we can check each lock in the home at the same visit.

Gated and hillside communities such as Westridge, Tesoro del Valle and Valencia Summit add another layer. Many homes there have builder-grade locks that have not been changed since the first owner, and a new homeowner may not know how many copies of the original keys are still out there. In those cases, duplicating keys is only half the picture. We can copy what you have and, if you would like, talk about rekeying so that old keys stop working. Gate remotes and access cards are managed by your HOA, so we stick to the locks on your own property.

In ZIP code 91354, closer to the Valencia Industrial Center and the areas around Magic Mountain Parkway, the demand shifts toward business keys: suite doors, storage rooms, equipment cabinets and shared entries. Tenants often need extra copies for employees, and some commercial keys are restricted, so we verify authorization before cutting. Whether you live near Westfield Valencia Town Center, work near Henry Mayo Newhall Hospital or CalArts, or commute along I-5, we come to wherever the key is needed. Call (323) 997-8867 any hour.

Key Duplication in Valencia — FAQs

Do you duplicate keys at a shop in Valencia?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home, office or business in Valencia and cut the keys on location. Call (323) 997-8867 to arrange a visit.
Can you copy a key stamped 'Do Not Duplicate'?
Often not without authorization. That stamp does not always mean a key is technically restricted, but we treat it carefully. We will explain what can be done and verify your authority where needed before cutting anything.
What are restricted keys, and can you copy them?
Restricted keys use protected blanks and controlled distribution, so only authorized people can get copies. We can help when you are the authorized party and the paperwork or key control process supports it. If not, we will tell you honestly and suggest alternatives such as rekeying.
Can you make copies of mailbox keys?
In many cases, yes. Mailbox keys in Valencia's townhome and condo villages are usually small, simple keys that we can cut on site. Some cluster-box systems are managed by the postal service rather than the property, in which case replacement goes through them.
Do you work with HOA or gated community keys in Westridge or Tesoro del Valle?
We copy the physical keys for locks on your property, such as doors, gates you own and mailboxes. Gate remotes, access cards and community entry systems are handled by your HOA, so you would contact them for those.
Can you duplicate office and business keys in the Valencia Industrial Center?
Yes, for keys we are able to cut and where authorization is clear. Commercial and master-key systems often have restrictions, so we verify who can approve copies. For more involved needs, call (323) 997-8867 and we will talk through the setup.
What if my original key is worn out?
A worn original can produce a copy that sticks or fails. We inspect it first and test every new key in your lock. If the copy does not work smoothly, we recut it, and may suggest replacing a tired lock.
Are you available at night or on weekends?
Yes. We are available 24/7 across Valencia and the surrounding area. Call (323) 997-8867 any time and we will work out what you need.
