Most people think of key duplication as a quick trip to a hardware counter. In Lake Balboa that trip usually means a drive along Balboa Blvd or Sherman Way, a wait, and then a copy that sticks in the lock when you get home. We bring the cutting equipment to you, so you can test the new key in your own door before we leave.
Crenshaw Lock Company is fully mobile. There is no storefront to visit, and we work around the day you actually have: early mornings before a commute onto the 101, evenings after work, or weekends when the park is busy and you would rather stay home. Owner and lead technician David Shar has been in the trade since 1987, and the same standards apply to every key we cut.
Duplication covers more than a plain house key. We copy standard residential keys, office and commercial keys, mailbox keys, and many restricted or keyed-control keys that ordinary kiosks will not touch. If a key is worn, bent, or a copy of a copy, we will tell you honestly whether a fresh copy will work well or whether rekeying the lock is the better answer.
How it works in Lake Balboa
- 1
You call and describe the key
Call (323) 997-8867 and tell us what you are copying: a front door key, a mailbox key, an office key, or one stamped with a do-not-duplicate marking. We will ask a few questions about the lock and where you are so we can come prepared.
- 2
We come to your location
Because we are mobile, we meet you at your home, apartment building, or workplace in Lake Balboa. You do not need to leave the property or hand your only key to a stranger at a counter.
- 3
We inspect the original key and lock
Before cutting, we look at the original for wear, bends, or damage, and at the lock it operates. A tired key produces a tired copy, and in older post-war hardware the lock itself may be the real problem.

We cut the copy on site
We cut the new key to match the original on equipment we bring with us, then deburr it so it enters and turns smoothly. Restricted keys follow the authorization requirements of the system they belong to.
- 5
We test it in your lock
Every copy is tried in the actual lock, multiple times, in both directions where it applies. If it binds or drags, we correct it right there rather than sending you off with a key that almost works.
- 6
We talk through next steps
If the lock is corroded, sticky, or tied to keys that have gone missing, we explain the options, such as cleaning, lubricating, rekeying, or replacing, and leave the decision to you.

What affects the price
- The type of key: a standard house key, a mailbox key, a high-security key, and a restricted-system key each take different blanks and different effort.
- How many copies you need, since a single spare is a different job than a full set for a household or a property with many units.
- Whether the original key is in good shape or worn enough that cutting from it is unreliable and a different approach is needed.
- Restricted or keyed-control systems, which may require proof of authorization and special blanks that are not available for ordinary keys.
- The time of day and day of the week you call, because we are available 24/7 and after-hours service differs from a scheduled daytime visit.
- Whether the lock also needs attention, such as cleaning, lubrication, or repair, in addition to the copying itself.
Why Lake Balboa chooses us
- Fully mobile service: the work happens at your door in Lake Balboa, with no shop visit and no leaving your only key behind.
- In business since 1987, with owner David Shar leading the work rather than handing it off to a call center.
- Every copy is tested in the real lock before we leave, so you find out about a bad cut while we are still standing there.
- We handle restricted and mailbox keys as well as ordinary house keys, so one call can cover the whole ring.
- Honest advice about when duplication is not the right fix: if a key is badly worn or has been lost, we will say rekeying may serve you better.
- Available 24/7, so a lockout-adjacent key problem does not have to wait for business hours.
Key Duplication across Lake Balboa
Lake Balboa sits flat and open around the Sepulveda Basin, with Lake Balboa and Anthony C. Beilenson Park, the Japanese Garden (SuihoEn) at Tillman, and Woodley Park all close by. The neighborhood was renamed from Van Nuys by the Los Angeles City Council in 2007, but the housing still reflects its mid-century roots. In the ZIP code 91406, you will find many small 1950s ranch and stucco tract homes, especially on the residential streets off Balboa Blvd, along with plenty of builder-grade locksets that have been in service for decades.
That age shows up in key work. Older post-war hardware often means keys that have been copied several times, so each generation is a little less accurate than the last. A new owner of a tract home near Balboa Blvd, for example, may be handed a mismatched ring of keys and want every exterior door working on a single key. We can copy what is sound and tell you plainly when rekeying all the doors to one key is the cleaner route. Homes close to the Sepulveda Basin have another issue: humidity and sprinkler overspray can leave an exterior deadbolt corroded and stiff, which wears keys and makes copies feel rough. In that case we can clean and lubricate the lock, or replace it if it is past saving.
Along the Victory Blvd and Vanowen St corridor, dense mid-century apartment complexes, plus some newer multifamily buildings, create a different need: managers and owners who want multiple units rekeyed or extra keys cut between tenants. We come to the property, work through the units, and keep the keys organized. Whether you are near Sherman Way, Hayvenhurst Ave, or Woodley Ave, call (323) 997-8867 any hour and we will come to you.
