Cluster mailboxes with a key in one mailbox lock

A mailbox lock is easy to ignore until the key snaps, the cam stops turning, or a tenant moves out and still holds a working key to the box. In San Gabriel, that can mean a wall-mounted box on a 1920s bungalow near the Mission, a row of boxes at a mid-century apartment building, or a cluster unit serving a newer townhome development. Each one calls for a slightly different approach.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around mobile service. We bring the tools and replacement hardware to you, work on the box where it stands, and test each lock before we leave.

We handle lost keys, jammed or worn cylinders, broken cams, and rekeying after a move or tenant turnover. Where a box belongs to a property owner or HOA, we replace and rekey the lock on that box. Locks on USPS-controlled equipment, such as the arrow lock on a cluster box's carrier door, are handled by the Postal Service, and we will tell you plainly which is which before we start.

How it works in San Gabriel

  1. 1

    Tell us about the box

    Call (323) 997-8867 and describe what you have: a private wall or post-mounted box, a multi-unit bank of boxes, or a cluster unit. Tell us what is wrong, such as a lost key, a stuck cylinder or a broken cam. That helps us bring the right hardware.

  2. 2

    We come to you

    We are fully mobile and available 24/7, so we travel to your address in San Gabriel. We start by confirming who owns the box and which lock is in question, so we only work on hardware that is yours or your property's to change.

  3. 3

    Inspect the lock and housing

    We check the cylinder, cam, latch and the door the lock sits in. Older boxes sometimes have rust, bent doors or loose mounting. We tell you if the lock can be rekeyed or if a replacement is the better option.

  4. 4

    Replace or rekey

    If the cylinder is sound, we rekey it to a new key. If it is worn, damaged or missing, we fit a replacement lock that suits the box. For apartments, we can set up new keys for each unit so previous tenants' keys no longer work.

  5. 5

    Test and hand over keys

    We test the lock repeatedly, check that the door closes and latches properly, and hand you the new keys. We also tell you how to get extra copies and what to do if a key is lost again.

What affects the price

  • The number of locks involved, since one private mailbox is a different job than a full bank of apartment boxes.
  • Whether the existing cylinder can be rekeyed or has to be fully replaced.
  • The type and condition of the box, including rust, bent doors or damaged cams that need extra work.
  • How many keys you need cut, particularly for multi-unit buildings with several tenants.
  • Whether the work is routine daytime service or an after-hours call at night, on a weekend or on a holiday.
  • Whether the lock is on your own box or needs coordination with an HOA, property manager or the Postal Service.

Why San Gabriel chooses us

  • Fully mobile service: we work on your box at your address, and there is no shop to drive to.
  • In business since 1987, with owner David Shar leading the work.
  • We are straightforward about which locks we can change and which belong to USPS, so you do not pay for work that is not allowed.
  • We can handle a mailbox together with other lock needs in one visit, such as a front door rekey or an apartment building turnover rekey.
  • Available 24/7, which helps when a lost key or a security concern cannot wait.
  • Experience with a mix of properties, from older Craftsman and Spanish-style homes to mid-century apartment stock.

Mailbox Lock Replacement across San Gabriel

San Gabriel has a mix of housing that shapes mailbox lock work. Around the Mission District and the streets near Mission San Gabriel Arcangel, founded in 1771, many 1900s to 1920s Craftsman and Spanish Colonial Revival bungalows keep their original character, and their wall-mounted or porch-side mailboxes are often just as old. Worn cylinders and loose cams are common there, and we aim to repair or replace the lock without damaging the look of the house.

Farther along Las Tunas Dr and the streets off it, mid-century apartment buildings are common. When tenants turn over, owners often want new locks on the mailboxes along with a rekey of common doors. We can replace or rekey a whole bank of boxes and cut separate keys for each unit. Along Valley Blvd's Golden Mile and San Gabriel Blvd, mixed-use buildings may have mailboxes for upstairs units alongside commercial storefronts, and we can work on both.

We serve San Gabriel ZIP codes 91775, 91776 and 91778, and can reach homes near Vincent Lugo Park, the Mission Playhouse district and around Del Mar Ave, with I-10 close by for access. Call (323) 997-8867 any hour, and we will come to you.

Mailbox Lock Replacement in San Gabriel — FAQs

Do you offer mailbox lock replacement in San Gabriel at night?
Yes. Crenshaw Lock Company is available 24/7 and fully mobile. Call (323) 997-8867 and we will talk through your situation, including after-hours needs.
Can you rekey my mailbox instead of replacing it?
Often, yes. If the cylinder is in good shape, we can rekey it so the old key no longer works. If it is worn, corroded or damaged, replacement is usually the better choice. We will tell you which applies after inspecting it.
I lost my mailbox key. What should I do?
Call us at (323) 997-8867. For a mailbox you own, we can typically open the lock and replace or rekey it so you have working keys. We will ask a few questions to confirm the box is yours.
Can you change the lock on a USPS cluster box?
It depends on which lock. Individual compartment locks on community or property-owned equipment can often be replaced, but the Postal Service controls its own arrow lock and carrier access. We will help you work out who to contact for those.
Can you do all the mailboxes in my San Gabriel apartment building?
Yes. After tenant turnover, we can replace or rekey a bank of mailbox locks and provide separate keys for each unit. Call (323) 997-8867 to describe the building and number of boxes.
Will you damage my older mailbox to replace the lock?
We work carefully, especially on older boxes near the Mission area. If a box is rusty or fragile, we will explain the options before we begin so you can decide how to proceed.
Do I need to come to a shop?
No. We are mobile only and have no storefront. We bring tools and replacement locks to your address in San Gabriel.
Can you handle other lock work during the same visit?
Yes. Many customers also have us rekey a front door, replace a deadbolt or service a gate lock while we are there. Mention it when you call (323) 997-8867.
