A mailbox lock is easy to ignore until the key goes missing, the cylinder starts to stick, or you suspect someone has been through your mail. In Sun Valley, where postwar homes, historic Stonehurst houses and industrial properties sit side by side, mailbox setups vary a great deal. Some are old wall-mounted boxes with worn cylinders. Others are cluster units at multi-unit properties, and some are boxes at small businesses that have changed hands or changed staff.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no shop to drive to. We bring the tools and parts to your address, whether you need a single lock replaced, a set of locks rekeyed to a new key, or a stuck cylinder dealt with before it fails completely.

Mail theft and lost keys are the two most common reasons people call us. Replacing or rekeying the lock means any key that was lost, copied or handed out before no longer works. We also help with boxes that were forced open, so the lock and the damaged parts can be dealt with in the same visit when it is practical. Call (323) 997-8867 any hour of the day or night.

How it works in Sun Valley

  1. 1

    Tell us about the mailbox

    When you call, describe what you have: a private wall or post box, a cluster unit, or a community box at an apartment or business. Tell us whether the key is lost, the lock is jammed, or the box was tampered with. That helps us bring the right cylinders and tools.

  2. 2

    We come to you

    We are a mobile service, so a technician drives to your Sun Valley address. We look at the box, identify the lock type and condition, and explain whether a rekey or a full replacement makes more sense.

  3. 3

    Remove or open the old lock

    If you have no working key, we open the lock with methods chosen to protect the box where possible. We then remove the old cylinder carefully, checking the door, latch and surrounding metal for wear or damage.

  4. 4

    Fit the new lock or rekey

    We install a replacement cylinder or rekey the existing one so it works with a new key. For shared boxes we can set up keys so each person has what they need and nothing more.

  5. 5

    Test and hand over keys

    We test the lock repeatedly, check that the door closes and latches cleanly, and hand you the new keys. If anything about the box itself looks weak, we tell you plainly so you can decide what to do.

What affects the price

  • The type of mailbox: a simple private box, a cluster unit or a community box can each need different parts and different labor.
  • Whether the lock can be rekeyed or has to be fully replaced, which depends on the condition and style of the existing cylinder.
  • How many locks are involved, since a single box differs from a group of boxes at an apartment building or business.
  • Whether the lock has to be opened because the key is lost, and how damaged the box or door is after a forced entry.
  • The time of day or night you call, since we operate 24/7 and after-hours service can be priced differently.
  • Any extra keys you need cut, or special keying requirements for shared or managed properties.

Why Sun Valley chooses us

  • We have been serving the Los Angeles area since 1987, so older and unusual mailbox hardware is not unfamiliar to us.
  • Fully mobile service means we come to your door, and there is no storefront for you to find or visit.
  • David Shar leads the work, so you are dealing with experienced locksmiths, not a call center passing jobs along.
  • We explain whether a rekey or a replacement is the better choice, instead of pushing the bigger job.
  • We handle single homes, multi-unit cluster boxes and business mailboxes, and can rekey several locks to a consistent system.
  • We are available 24/7, which matters when a lost key or a tampered box cannot wait.

Mailbox Lock Replacement across Sun Valley

Sun Valley has a mix of properties that shapes the mailbox work we see. In the historic Stonehurst neighborhood, 1920s stone and clinker-brick homes often have original mailboxes or hardware that deserve careful handling. We aim to replace or rekey the lock without damaging the character of the house, and we can look at the front door hardware in the same visit if you want it matched or upgraded.

Across the 91352 ZIP code, you will find modest postwar homes, small multi-unit buildings and businesses along San Fernando Road, Glenoaks Boulevard and Sunland Boulevard. Landlords and property managers near the San Fernando Road industrial corridor sometimes call after tenant or staff turnover, when old mailbox keys are still floating around and rekeying is the practical fix. Business owners near the Hollywood Burbank Airport side of the district may want mailbox locks handled alongside door and gate work.

We reach Sun Valley from I-5 and CA-170, and we cover homes near La Tuna Canyon at the foot of the Verdugo Mountains as well. Wherever you are, call (323) 997-8867 and we will come to you.

Mailbox Lock Replacement in Sun Valley — FAQs

Can you replace a mailbox lock if I have lost the key?
Yes. We can open the lock without the key, then replace or rekey it so a new key works. Call (323) 997-8867 and tell us what kind of box you have.
Should I rekey or replace my mailbox lock?
If the cylinder is in good shape, rekeying is often enough and makes lost keys useless. If it is worn, corroded or damaged, replacement is the better choice. We will tell you which applies after seeing it.
Do you work on cluster and community mailboxes in Sun Valley?
Yes, we work on residential, cluster and community mailbox locks. Apartment buildings and small business properties in Sun Valley often need several locks handled together.
What if my mailbox was broken into?
We can replace the lock and look at the door and latch for damage. If the box itself is badly damaged, we will say so. Call (323) 997-8867 to describe what happened.
Do I need to visit your shop?
No. We are fully mobile and have no storefront. A technician comes to your Sun Valley address with the tools and parts.
Are you available at night or on weekends?
Yes, we are available 24/7. If your mailbox lock is jammed or compromised, you can call any time.
Can you rekey mailbox locks after tenants or employees leave?
Yes. Rekeying means old keys stop working, which is useful for landlords and business owners after turnover. We can also provide extra keys as needed.
Can you work on mailboxes at older Stonehurst homes?
Yes. We take care with older boxes and hardware, and aim to replace or rekey the lock without unnecessary damage to the original look of the home.
