Replacing a cam lock on an apartment cluster mailbox

What do you do when you lose your mailbox key?

A lost mailbox key is a small problem that gets bigger every day. Mail keeps arriving and you can't reach it. Some of what lands in that box, such as bank cards, tax forms, medical bills and replacement keys for other things, is exactly what you don't want sitting behind a lock you can't open. Meanwhile, if the key is out there somewhere, you don't know who might be holding it.

The situations usually fall into a few groups. A new tenant moves in and the previous resident never handed over a mailbox key. A key snapped off in the cylinder. A lock has gone stiff and now grinds or catches. A box has been pried at and the latch no longer seats. Or the lock works fine, but you have no idea how many copies of its key are floating around. Each of these has a different fix, which is why we ask questions on the phone before we say anything else.

This page covers mailbox lock replacement, mailbox lock change, lost mailbox key replacement and new mailbox lock installation for Hawthorne homes, apartment buildings and community mailbox setups. It also covers the honest part nobody likes to lead with: some mailboxes aren't ours to open.

Is a mailbox lock your job to fix, or the post office's?

The honest answer depends on who owns and controls the box. A mailbox is not like a door lock, and sending a locksmith to the wrong kind of box wastes your time.

If the box belongs to you or your building owner, it's a normal locksmith job. That means a wall-mounted or post-mounted box at a house, a curbside box you bought and installed, or a mailbox panel a property owner put into an apartment building. We replace those locks all day.

Boxes that belong to the U.S. Postal Service, or whose main access lock is controlled by the post office, are a different story. Cluster box units and some apartment mailbox panels fall into this group, and the carrier's access lock is typically handled by the post office, not by a private locksmith. If that's what you have, your first call should be to your local post office. Who controls the individual compartment locks varies from property to property, so tell us what you're looking at and who manages the building. If it turns out the post office has to handle it, we'll say so on the phone rather than send a van for a job we shouldn't touch.

We also ask for a reason to believe you're entitled to open the box. Mail is protected, and a locksmith who opens any mailbox for anyone who asks isn't doing the job properly. Expect us to ask you to show that you live at the address, or that you own or manage the property.

  • Privately owned standard box (wall, post or curbside): we can replace the lock.
  • Apartment mailbox panel installed by the property owner: usually ours, with the owner's or manager's okay.
  • Cluster or community box where the post office controls access: call the post office first; we'll confirm which parts, if any, are ours.
  • Not sure who owns it: call us at (213) 577-1366 and describe it; we'll sort it out with you.

How does mailbox lock replacement work, step by step?

Most mailbox jobs are short and clean once we're on site. The slower part is figuring out the box, which is why the early steps matter.

  1. You call (213) 577-1366 and tell us the address, the type of box (single box, apartment panel or cluster unit), and what's wrong: lost key, broken key, stuck lock or damage.
  2. We work out who controls the box. If it's a post office lock, we tell you that up front. If it's privately owned, we send a technician.
  3. A technician comes to you in one of our mobile vans, carrying cylinders in the common mailbox sizes and a key machine.
  4. We confirm that you live there or manage the property before we touch the box.
  5. We open the box. Where the lock can be opened without damage, we do that. When it can't, we drill or remove the cylinder in a way that keeps the box door and frame intact where possible.
  6. We take out the old cylinder and fit a new lock matched to your box: the right body length, the right cam, and the right cutout shape so it sits flush and latches properly.
  7. We cut new keys, test the lock several times with the door open and closed, and hand over the keys. We'll also suggest a spare, because the next lost key is the most predictable thing in the world.

What kinds of mailboxes can we replace the lock on?

A mailbox lock is usually a small cylinder with a cam on the back that turns into a latch. Replacing it means matching the cylinder's thickness, the cam's shape, and the opening in the door. A lock that is slightly wrong will turn but not catch, or catch but wiggle loose in a month. That's why we match the lock to the box rather than grabbing whatever's closest.

Here's what we typically handle:

  • Standard mailboxes on houses: wall-mount, post-mount and curbside boxes with a keyed lock.
  • Apartment mailbox lock replacement: banks of individual doors in a building's entry or breezeway, including replacing one tenant's lock or several at once.
  • Cluster mailbox lock and community mailbox lock service where the property, not the post office, controls the individual compartment locks.
  • Mailbox lock repair: a worn cylinder, a bent cam, a sticky latch or a lock that turns but doesn't release.
  • New mailbox lock installation: a box that never had a lock, or one where the old lock was removed or pried out.
  • Mailbox key replacement when the cylinder is fine but you only have a single worn key and need working copies.

What about a broken mailbox key or a stuck lock?

Mailbox keys are small and thin, which means they bend and snap. If part of a key is stuck in the cylinder, don't keep jiggling it or push it deeper with another key. Every attempt wedges the piece in tighter. A broken mailbox key extraction is a quick job when the piece is still reachable. If the cylinder is old and worn, it often makes more sense to replace it than to save it. For the general version of this work on doors, see our page on broken key extraction.

A stuck or grinding mailbox lock is usually one of three things: a worn cylinder, a bent or worn key, or a latch that's out of alignment because the door has been slammed or forced. We look at the key first. Often a freshly cut key from the original code or a good copy works better than a tired one. If the cylinder is the problem, we replace the cylinder. If the door or frame is bent, we tell you, because a new lock won't fix a crooked box.

Hawthorne's climate is on our side here. A few miles inland, the marine-layer mornings and mild temperatures mean weather rarely destroys a mailbox lock on its own. Most failures we see on a box this age come down to wear, bent keys and forced entry, not rust. For a wider look at replacing locks on doors, see lock replacement.

What affects the cost of mailbox lock replacement?

We don't quote numbers on a web page because the job really does vary, and we'd rather explain how the cost works than throw out a figure that doesn't fit your box. When you call, we'll talk through your situation and tell you what to expect before any work starts.

Replacing just the cylinder is usually the more economical route compared with replacing an entire box or panel, and it's the option we try first. Here's what moves the cost up or down:

  • The type of box: a single standard box, an apartment panel, or a cluster or community unit with many compartments.
  • Whether the lock can be opened with a key or has to be drilled out because the key is lost or broken.
  • Whether a key is stuck inside the cylinder and needs extraction first.
  • Whether the door, latch or frame is damaged, which can mean extra repair work beyond the lock itself.
  • How many locks are involved: one tenant's box, or several boxes in a building.
  • How many keys you need cut, and whether you want the locks keyed alike or separately.
  • When you call: after-hours and holiday visits are part of what we do, and timing can be a factor in the quote.
  • Where the box is and how easy it is to reach.

Mailbox lock replacement around Hawthorne and ZIP 90250

Hawthorne is a mix of housing types, and each one gives mailboxes a slightly different problem. Our storefront is on Wilshire Boulevard in Westwood, about 15 miles from Hawthorne, so most calls here are handled by a mobile van that comes to you. If you want to understand how that works, read about our mobile locksmith service.

In the postwar tract neighborhoods like Hollyglen and Bodger Park, the mix is mostly 1940s to 1960s stucco single-family homes. A house with an older wall-mounted or curbside box often has a lock that's been working for decades and is simply worn out. Replacing the cylinder and cutting fresh keys is typically the whole job, and it's a good moment to make sure the house has working spares. The same goes for streets around Moneta Gardens and North Hawthorne, where older homes tend to hold on to their original hardware.

The apartment corridors are a different situation. Hawthorne has dingbat-style apartment buildings concentrated along Hawthorne Boulevard and other commercial corridors. In a building like that, the mailboxes often serve as the first thing a new tenant realizes they don't have a key for. If a previous resident left with the mailbox key, or a unit's lock is jammed, the owner or manager can arrange a replacement for that one door or several at once. If you're a tenant who is also locked out of the unit itself, that's a separate service; see apartment lockout. Property owners and managers who handle turnover regularly can read about our work for landlords.

ThreeSixty at South Bay, the newer gated townhome community on the west side, is a different case again. Communities like this often rely on shared mailbox setups and management rules, and who may authorize a lock change is usually the HOA or property manager. If you live there, check with management first, and if the gate hardware itself is giving trouble, that falls under gate lock repair. Whatever your address in 90250, tell us the location and the kind of box when you call, and we'll work out the right approach.

Why call Wilshire Lock & Key for your mailbox lock?

We've been in business since 1987, and a mailbox is one of those small jobs that tells you quickly whether a company pays attention. We match the cylinder to the box instead of forcing something close enough, and we tell you honestly when the post office is the one to call.

Here's what you get when you call us:

  • One company, start to finish. The person who answers the phone works for the same company that sends the van. There's no dispatch middleman passing your job to whoever is free.
  • A storefront and mobile vans. We have a real shop at 10740 Wilshire Blvd in Los Angeles and vans on the road serving 140 cities across Los Angeles and Ventura counties, Hawthorne included.
  • David's oversight. David, the owner and lead technician, sets how work gets done here, and that includes the small jobs.
  • Phones answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, because lost keys don't wait for business hours.
  • Plain talk. If the fix is a cylinder, we say a cylinder. If the box is the post office's, we say that.

How do you keep from losing the next mailbox key?

Once the new lock is in, a few habits help. Cut at least one spare right away and keep it somewhere other than your main key ring. If you've been through a messy move-out, a breakup, or a roommate leaving, or you simply don't know who has old keys, a fresh lock is the cleaner option, and our key duplication service covers the spares.

If your issue is the front door, not the mailbox, and you want the same keys to stop working there too, look at lock rekey. It's a separate job that changes how a door's lock works without replacing the hardware.

Also look at the box itself when the technician is there. A door that doesn't close flush, a dented frame or a loose mounting is worth fixing at the same visit. A new lock only protects your mail if the box around it is sound.

Ready to get your mailbox working again?

Call (213) 577-1366, any hour of any day. Tell us your address in Hawthorne, what kind of box it is, and what happened to the key. We'll tell you whether it's ours to handle, what will affect the cost, and what to expect when the technician arrives. If your project is bigger than a mailbox, you can also reach us through our contact page.

Frequently asked questions

I lost my mailbox key. Can you replace the lock in Hawthorne?

Yes, if the box is privately owned, such as a house mailbox or an apartment panel the property owner installed. We open the box, replace the cylinder with one that matches, and cut new keys. If your box is a post office controlled cluster unit, we'll say so on the phone and point you to the post office.

Do I need to call the post office or a locksmith for a cluster mailbox?

It depends on who controls the compartment locks. The post office generally handles its own access locks on cluster units. Individual compartment locks vary by property, so call us, tell us what you see and who manages the building, and we'll help you figure out the right call.

Will you ask for proof that I live here?

Yes. Mail is protected, so we ask you to show that you live at the address or that you own or manage the property before we open a box. It's a short check, and it's part of doing the job right.

Can you make a new key without replacing the lock?

Sometimes. Many mailbox cylinders have a code stamped on them, and if it's readable we can often cut a key from it. If the code is worn off, the cylinder is damaged, or you have no key to copy, replacing the cylinder is usually the more reliable fix.

What if my key broke off inside the mailbox lock?

Stop turning it and don't push another key in. We can extract the broken piece if it's reachable. If the cylinder is badly worn, we may replace it instead, which also gets you fresh keys.

How much does mailbox lock replacement cost?

It depends on the type of box, whether the lock must be drilled, whether a key is broken inside, how many locks are involved, whether the door or latch is damaged, and when you call. Replacing only the cylinder is usually the more economical route. Call (213) 577-1366 and we'll go over what applies to your box before work starts.

Can you replace locks on several apartment mailboxes at once?

Yes, if the property owner or manager has authority over the boxes. We can replace one lock or a whole bank, and key them separately or alike depending on what the building wants.

Do you come out at night or on weekends?

Yes. We answer the phone 24 hours a day, 7 days a week, year-round at (213) 577-1366, and our mobile vans serve Hawthorne from our Westwood base.

Should I replace the lock or just get a spare key?

If the lock works well and you simply need another key, a spare is enough. If the lock is worn, the key is lost and you don't know who has it, or the box has been forced, replacing the lock is the better choice.
