A mailbox lock is easy to ignore until the key goes missing, a former tenant still holds a copy, or the lock starts to bind and the door will not open. In Glendale, where a large share of residents rent and buildings change hands and managers often, mailbox keys tend to circulate far longer than anyone intends. Replacing or rekeying the lock is a small job that closes a real gap in the security of your mail, your statements and anything else delivered to your address.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit; David Shar and our technicians bring tools and parts to you, day or night. That matters for mailbox work because the box is fixed to a wall, post or cluster unit and cannot simply be carried in for service.
We handle single residential boxes, wall-mounted units in older Glendale buildings, cluster box units in newer developments and the locks on community mailbox banks in apartment and condo properties. Where the lock type allows, we rekey rather than replace, which keeps the existing hardware in place. Where a lock is worn, damaged or broken, we replace it with a suitable cylinder.
One important note: USPS-owned equipment, such as many centralized delivery units and the postal arrow locks on them, is managed by the Postal Service. If you are unsure who is responsible for your box, ask us when you call and we will help you sort out whether the lock is yours to change.
How it works in Glendale
- 1
Tell us about your mailbox
When you call (323) 997-8867, describe the box: a single wall or post-mounted unit, a cluster box, or a community bank in a building. Mention whether you have a working key, and whether the lock is jammed, lost or being changed for security reasons.
- 2
We come to you
Because we are fully mobile and available 24/7, a technician travels to your home or property with a range of cylinders and rekeying tools. There is nothing to drop off and no shop to visit.
- 3
Confirm ownership and inspect the lock
On site we look at the box and the lock type and confirm the equipment is yours or your property's to service. We check the door, the latch and the cam, since a lock that sticks is sometimes a bent cam and not a bad cylinder.
- 4
Rekey or replace
If the lock is in good condition, we can often rekey it so old keys no longer work. If it is worn, broken or missing, we fit a new cylinder that suits the box and set it up with fresh keys.
- 5
Test and hand over keys
We test the new lock several times with the door open and closed, make sure the mailbox door latches cleanly, and hand over the keys. For multi-unit work, we label and organize keys by box so a property manager can keep clear records.

What affects the price
- Whether the lock can be rekeyed or must be fully replaced because of damage, wear or a missing cylinder.
- The type of box: a single residential mailbox, a cluster unit or a community bank can each need different cylinders and tools.
- The number of boxes in the job, since a building-wide change involves more time and key organization than a single lock.
- Whether the lock is jammed or the door is damaged and needs extra work to open or realign before the new lock goes in.
- How many keys you want cut and whether the property needs a documented key system for the manager.
- The time of day you call, as after-hours and urgent calls are handled differently from scheduled daytime work.
Why Glendale chooses us
- Fully mobile service since 1987: we come to the mailbox instead of asking you to bring anything anywhere.
- Available 24/7, so a lost key or a jammed box does not have to wait for business hours.
- We prefer rekeying when the existing lock is sound, which can save you the cost of unnecessary hardware.
- We are upfront about who owns the equipment, so you do not pay to change a lock that actually belongs to the Postal Service.
- Experience with older buildings and multi-unit properties, including organizing keys by unit for managers and owners.
- Owner-led operation under David Shar, so the standards on a small mailbox job match those on any other.
Mailbox Lock Replacement across Glendale
Glendale's housing stock gives mailbox locks a lot of variety. In Rossmoyne and Adams Hill, 1920s Spanish and Mediterranean Revival homes often have original wall-mounted or built-in mail slots and boxes that have outlasted several owners and many keys. If you are already servicing original mortise hardware on the front door, it makes sense to address the mailbox at the same visit so the whole entry is on one key plan. In Verdugo Woodlands, hillside homes frequently use street-side or post-mounted boxes that face weather and need a cylinder that still turns smoothly.
The bigger demand often comes from multi-unit buildings. Glendale has a high share of renters and a large inventory of 1960s to 1980s apartments and condos, and when a property manager changes, the old mailbox keys are one of the first things worth resetting. A building near downtown with twenty or more units can have its community mailbox locks rekeyed in one visit, with keys sorted by unit. Residents of Brand Boulevard high-rise condos, who may already have fob or access-control entry, sometimes still rely on a basic mailbox key that deserves the same attention.
We serve Glendale across ZIP codes including 91201, 91202, 91203, 91204, 91205, 91206, 91207 and 91208, whether you are near the Americana at Brand, the Glendale Galleria, Central Avenue, Glenoaks Boulevard or tucked against the Verdugo Mountains. Call (323) 997-8867 any hour and we will head your way.
