Sun Valley is a mix of working warehouses, yards and quiet residential streets, and the keys people need copied here reflect that. A property manager behind Hollywood Burbank Airport may need a dozen copies of a man-door key for a new shift crew. A family in a 1920s Stonehurst house may need a spare of an old key before the only one finally wears out. Either way, a copy made from a worn original is only as good as the cutting, and that is where experience matters.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We are fully mobile, so key duplication happens at your door, your gate or your loading dock instead of at a counter across town. We are available around the clock, which matters for businesses that run odd hours and for homeowners who discover on a Sunday night that they have no spare.

Key duplication sounds simple, but it covers a lot of ground: standard house keys, office and suite keys, small mailbox keys, and restricted or keyed-control systems that most hardware-store machines will not or should not copy. We will tell you plainly what can be copied, what needs authorization, and when a rekey makes more sense than another copy of a key that has been floating around for years.

How it works in Sun Valley

  1. 1

    You call, we talk through the keys

    Call (323) 997-8867 any hour. Tell us what you need copied: house, office, mailbox or restricted keys, and roughly how many. Mention the property type, such as a warehouse, a yard gate or an older Stonehurst home, so we bring the right blanks and equipment.

  2. 2

    We come to your location

    Because we are fully mobile, our technician drives to you in Sun Valley. There is no shop to visit. That means you can stay on site, keep a business running, or avoid leaving a property unattended.

  3. 3

    Inspect the original key and the lock

    We examine the original for wear, bends or poorly cut grooves. A worn key copied directly passes its flaws to the duplicate, so if needed we work to the lock's proper specification instead. We also check that the lock actually operates smoothly.

  4. 4

    Cut and test each copy

    We cut the copies on location, then test every one in the lock it is meant for. A key that merely looks right but binds or sticks gets recut or replaced, not handed over.

  5. 5

    Handle restricted keys properly

    Restricted keyways are designed so copies cannot be made casually. For those, we confirm authorization before duplicating, which protects you and the security of the system.

  6. 6

    Advise on rekeying if it makes sense

    If keys have gone to former employees, contractors or tenants, we will explain whether rekeying is wiser than adding more copies. The choice stays yours.

What affects the price

  • The type of key: a standard house key differs from a high-security, restricted or specialty key in blanks and cutting effort.
  • How many copies you need, since batches for a crew or a multi-door building are handled differently than a single spare.
  • The condition of the original, because a badly worn key may need to be cut by code or by working from the lock itself.
  • Whether authorization is required for a restricted keyway before copies can be made.
  • Time of day and location, since we operate 24/7 and mobile and after-hours visits can be priced differently than daytime ones.
  • Whether additional work such as rekeying or lock repair is needed alongside the duplication.

Why Sun Valley chooses us

  • Fully mobile service: we cut keys at your door, gate or dock, so there is no storefront trip and no leaving a site unattended.
  • Operating since 1987, with owner and lead tech David Shar bringing long experience to both residential and commercial work.
  • Comfortable with industrial settings, from roll-up doors and man-doors to yard-gate hardware along San Fernando Road.
  • Respect for older homes: we handle original 1920s hardware carefully and suggest sympathetic options instead of wholesale replacement.
  • Honest about restricted keys: we follow authorization practices rather than copying anything for anyone.
  • Available 24/7, so a missing spare or a staffing change does not have to wait for business hours.

Key Duplication across Sun Valley

Sun Valley sits at the base of the Verdugo Mountains, and its character changes block by block. Along San Fernando Road and the corridor behind Hollywood Burbank Airport, warehouses, manufacturing shops, auto-dismantlers and recycling yards depend on dependable keys for roll-up doors, man-doors and hardened gate padlocks. When staff turns over, one copy too many can become a security question, and we can duplicate what you need and talk through rekeying where it fits. Many of these sites are within reach of Glenoaks Boulevard, Sunland Boulevard, Vineland Avenue, I-5 and CA-170, which makes mobile service practical across the district.

The residential side has its own needs. In Stonehurst, near the historic Stonehurst Recreation Center, 1920s stone and clinker-brick homes often still carry original hardware. Spare keys for those locks can be old, worn and hard to match, so we take care to copy accurately and, if you want, suggest a deadbolt upgrade that suits the house. Postwar homes elsewhere in 91352 usually need simple spares for family members, tenants or house sitters, and mailbox keys are a common small request.

Further toward La Tuna Canyon, properties can be spread out and farther from the main roads, which makes a mobile visit especially convenient. Whether you are near the LADWP Valley Generating Station smokestacks, close to the Pink Motel on San Fernando Road, or tucked into a quiet street in 91352, call (323) 997-8867 and we will come to you.

Key Duplication in Sun Valley — FAQs

Do you copy keys at a shop in Sun Valley?
No. Crenshaw Lock Company is fully mobile and has no storefront. We come to your home, business or yard anywhere in Sun Valley. Call (323) 997-8867 to arrange it.
Can you duplicate keys at night or on weekends?
Yes. We are available 24/7, so you can call (323) 997-8867 at any hour about a spare, a batch of copies or a key problem.
Can you copy a restricted or 'Do Not Duplicate' key?
Restricted keyways are built to prevent casual copying. We confirm authorization before duplicating them, which keeps the system secure. Call us and we will explain what is needed for your key.
My original key is badly worn. Will the copy work?
Copying a worn key can pass along its flaws. We inspect it and, when needed, cut to the lock's proper specification and test each copy in the lock before we finish.
Can you make many copies for a warehouse or yard crew?
Yes. Businesses along San Fernando Road and near the airport corridor often need multiple copies. We can also advise whether rekeying is smarter if keys have gone to people who no longer work there.
Do you handle keys for old Stonehurst homes?
Yes. Original 1920s hardware can be worn or unusual. We copy carefully and can suggest a sympathetic deadbolt upgrade or rekey that fits the house.
Can you copy mailbox and office keys too?
Yes. We cut house, office, mailbox and restricted keys on location. Tell us what you have when you call (323) 997-8867 so we bring the right blanks.
Should I copy a key or rekey the lock?
If you only need a spare and trust everyone holding keys, a copy is fine. If keys have been lost or given to people who no longer need access, rekeying is usually the better step. We will give you an honest recommendation.
