Most key copying happens at a counter, which means a trip across the Valley with a key you may not want to hand over. In Winnetka, our work comes to you instead. We cut copies at your home, apartment, office or parking lot, so you can verify the copy works in your own lock before we leave.

Winnetka has a lot of rental housing and a lot of older tract homes, and both create steady demand for copies. A property manager may need spare keys for several units after move-outs. A family in a 1950s or 1960s house may only have one worn key left to the front door. A condo owner may need a copy that works with the building's common entry as well as their unit. Each of these calls for a slightly different approach.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. Key duplication sounds simple, but a good copy depends on the condition of the original, the key blank, and whether the key is restricted. We take care with each of those details, and we tell you plainly when a key should be replaced rather than copied.

How it works in Winnetka

  1. 1

    Call and describe the key

    Call (323) 997-8867 and tell us what you need copied: a standard house key, an office key, a mailbox key, or a key stamped with a do-not-duplicate marking. Let us know how many copies you want and whether the original still works smoothly.

  2. 2

    We come to your location

    Because we are fully mobile and available 24/7, we drive to your Winnetka address with our key-cutting equipment and a range of blanks. There is no shop to visit, and your original key stays in your sight the whole time.

  3. 3

    Inspect the original and match the blank

    We look over the original for wear, bends and damage, then choose the correct blank for the lock brand and keyway. A badly worn original can produce a poor copy, so we flag that before cutting.

  4. 4

    Cut and finish the copy

    We cut the new key and remove burrs so it enters and turns cleanly. A rough edge can wear down a lock's pins, so finishing matters as much as cutting.

  5. 5

    Test in the actual lock

    We try the copy in your lock several times, checking that it turns smoothly and the bolt moves fully. If it sticks, we adjust or recut it before we consider the job done.

  6. 6

    Restricted keys and authorization

    Restricted keyways are controlled and are not copied on request alone. If your key is restricted, we explain what authorization is needed, which is common with some apartment, HOA and commercial systems.

What affects the price

  • The type of key: a basic house key differs from a high-security, restricted or specialty key in blank cost and cutting effort.
  • The number of copies requested, since a batch for several units is handled differently than a single spare.
  • The condition of the original, because a worn or damaged key may require extra work or a different approach, such as rekeying instead.
  • Whether the key is restricted and requires authorization or special blanks.
  • The time of day and your location within our service area, since we are mobile and operate around the clock.
  • Whether copying is combined with other work, such as rekeying a unit to match a common key.

Key Duplication across Winnetka

Winnetka sits in the central-west San Fernando Valley, and its housing shapes the key work we see. The Winnetka Ave and Sherman Way residential core is largely 1950s and 1960s single-family tract homes, where original front-door locksets are often still in use and keys have been copied from copies for decades. A fresh copy cut from a worn key can inherit its flaws, so we often recommend cutting from the best original available or replacing the lockset.

Along the Vanowen St multifamily corridor and the De Soto Ave apartment district, mid-century and 1970s-80s complexes bring frequent tenant turnover. Property managers there may need spare unit keys, mailbox keys and sets for maintenance staff, sometimes alongside rekeying after move-outs. Condo owners near these streets may also need a unit key that works with the building's common-entry system. We can handle these requests on site, in the ZIP code 91306 and nearby.

We work around landmarks locals know, from the Winnetka Recreation Center and Prairie Street Elementary to Winnetka Bowl on Vanowen St and the retail near the former Winnetka Drive-In site. Whether you are off Roscoe Blvd, Saticoy St, Mason Ave or Victory Blvd, or near Northridge Fashion Center, call (323) 997-8867 and we will come to you.

Key Duplication in Winnetka — FAQs

Do you copy keys at a shop in Winnetka?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home, apartment or office in Winnetka and cut the key there. Call (323) 997-8867 to arrange it.
Can you copy a key marked Do Not Duplicate?
That marking is not always a legal barrier, but restricted keyways are different and usually require authorization. We explain what is needed for your key before cutting anything.
Can you make copies for several apartment units?
Yes. Property managers along Vanowen St and De Soto Ave often need sets for multiple units. We can cut them on site and rekey units too if needed.
Can you copy a mailbox key?
Often yes, depending on the mailbox lock type. Condo and HOA mailbox locks vary, so describe it when you call (323) 997-8867 and we will confirm what is possible.
My only key is badly worn. Should I just copy it?
Maybe, but a copy from a worn key can work poorly. We inspect it first and may suggest rekeying or replacing the lock, which is common with original tract-home locksets.
Are you available at night or on weekends?
Yes, we are available 24/7. Call (323) 997-8867 any time and we will talk through your key and set up a visit.
Can you make my unit key match the building's common-entry key?
In many cases we can rekey a unit deadbolt so it works with the existing key system. We would need to know the setup and confirm you are authorized to make the change.
How do I know the copy will work?
We test it in your actual lock before leaving, checking that it inserts, turns and moves the bolt smoothly. If it does not, we adjust or recut it.
