List of Top-Rated Residential Locking Mailboxes

Mailboxes are federally regulated devices used to secure mail. They must meet certain requirements and come in a specific form. As such, a standard locking mailbox will come in pre-defined dimensions and materials that conform to the United States Postal Office regulations.

A metal mailbox can be made from various materials, including aluminum, steel or copper. A copper mailbox usually comes with specific design features since copper is a more expensive metal to use than steel and aluminum. Some mailboxes are made from thick polymers which are now coming into the market with their all-weather resistant properties combined with strong yet inexpensive deisgns.

There are a number of options to choose from, including a wall mount mailbox, a standard pole hung mailbox and a special USPS mailbox. In this article, I will review 10 secure mailbox options. Before I begin, let’s take a look at a few issues that confront mailbox owners.

How to pick a mailbox lock

Residential mailboxes come with standard locks and keys, so when you misplace your key, there are options to opening the box, and making it easier to replace the mechanism, as well as access your mail at the same time.

To access a metal mailbox, you will first need to prepare a lockpick and lever.

There are professional tools available at your local locksmith, or online, however, if you don’t have the time to buy one, here is a simple way to pick your lock using home and office appliances.

Make Lock Pic

Making a homemade lockpick is easier than you think, what you need 2 hairpins or 2 paper clips.

  1. Take a hairpin and bend it so that the two halves are at 90 degrees to each other.
  2. Now take the second hairpin, bend one end of the hairpin, so it is not straight, and taking a pair of pliers, bend the end of the hairpin section so that it is about 1.3cm away from the curved part you bent; this is the lever.
  3. For paperclips, straighten out one half of the paper clip and bend the straightened half upwards slightly.
  4. Take the second paper clip and straighten it out all the way, just leave the last turn to act as leverage when holding it, this is the lever.

Pick the Lock

To pick the lock, you insert short side of the lever into the lock. Press the long end of the lever and turn it clockwise (or the direction you use to open the lock) and maintain this pressure to turn the tumbler. While you do this, insert the lockpick component and feel for the spring loaded pins, applying pressure and moving the lever to force the tumbler to open.

Consider that there are 5 pins in a conventional lock, start with the first pin and push it up, the pressure of the lever will force the pin to retain its upright position as the tumbler moves slightly to cover the exit hole. You need to make sure the pin is seized, this is felt as tight push, if the pin moves up smoothly it’s not seized and won’t lock when pushed, once there is some resistance, it means the pin will lock in he up position. Now move onto the next pin. You will hear a faint clicking sound that tells you the pin is locked open.

Remember, turn the clock with the lever so that each pin feels seized, and keep this in mind: “a loose pin is bad, a tight pin is good.”

Using the lever, rotate the barrel once the last pin is unlocked.

How to secure mailbox

There are two kinds of mailboxes, the pole and the wall mounted types. Both mailboxes do sometimes loosen over time, and to secure a mailbox you will need to perform some DIY tasks.

The wall mailbox is easy to secure, you just open it and tighten the screws found on the inside of the body.

For outside post mailboxes, you need to look at the way the mailbox has been loosened and approach each issue individually.

Start by assessing the damage, is the box still fattened to the post, or is it broken off. How bad is the overall damage? Are the door and flag still working properly?

For securing the box to the post when it is only slightly loose, just screw the box back on. However, if the metal bracket or connectors are damaged, you will need to replace them. Also, check the post. If it wobbles, you might need to replace it completely, or in some instances just reinforce it.

  • Wooden posts are easier to fix since you can cut and add parts. Metal posts are problematic, and it best to fully replace those.
  • Mounting brackets can be bought online as replacements for broken or damaged mounting brackets, just make sure you buy the replacement part from the original maker, if you don’t have such an option, try to buy a universal bracket.
  • In the instance of a bad fit, use a board of wood between the mounting bracket and the box, this will solve your situation much faster.
  • Most brackets don’t come with screws, so make sure you have galvanized deck screws. You will need 4 x 1.75”, and 4 x 0.75”.
  • To aid in securing the plates and brackets, pre-drill holes in a new post, or use the old holes if there are any that are still usable, but check to see if they are good or not.
  • Screw the bracket into the post and then secure the mailbox to the bracket.

How to install a mailbox

There are two ways to secure a mailbox post; one is with concrete the other is without. Check to see if your local regulations support concrete supports, if so, continue, if not, secure the mailbox post without concrete.

If you need to replace the post or install a brand new mailbox unit, these are the steps to take.

With Concrete

  1. Dig a 1-foot diameter hole that is 2 feet deep in the ground according to USPS guidelines.
  2. Add 6 inches of dry gravel after digging it; this acts as a water drain for the concrete. It’s best to use standard gravel stones.
  3. Mix the concrete and prepare it in a bucket ready for pouring.
  4. Set the post into the hole and check its height so see it conforms to USPS regulations. Use a level to check for its vertical integrity.
  5. Pour the concrete into the hole around the post, use a trowel for accuracy, it maintains a cleaner environment and also makes user there are fewer air holes. Level the concrete to within 3 to 4 inches from the surface.
  6. Allow the concrete to set, and then fill in the remaining gap with gravel or dirt.
  7. After the concrete is set and the ground I covered, attach the mounting bracket and fasten the mailbox. Check the mailbox for a secure and tight fitment.

Without Concrete

  1. The process is similar to that with concrete, however here you will not fill up the area with concrete, instead, you will pack it with dirt. As such, the diameter of the hole will be slightly wider, and you usually pack the dirt harder. Make sure you use fine dirt and not loose stones, loose stones do not bind over time, and will remain loosely fitting. Some people like to secure a wide base at the bottom of the post and place stones on top of the lip, this is also useful but requires a much wider hole which makes work longer and harder.

How to install mailbox lock

On many occasions, locks get damaged or owners loose keys. Changing a lock on a residential mailbox is not a big issue, and all you need is a replacement lock that you can buy from a locksmith or online. There are some basic tools that are required, and these include a drill for damaged locks that don’t open and screwdriver. Before you buy a new lock, its best to remove the old one to check the exact dimensions that will fit into your door.

If the lock doesn’t open, drill through it with the drill bit. If it does open then open the door and unscrew or unclip the lock mechanism from the door.

Once you have the old lock, replace it with a new one, all you need to do is either clip it in place or screw it in place.

How to get mail out of a locked mailbox

Mailbox fishing, yup, this is a criminal profession that can come in useful when a mailbox owner loses a key or has a damaged lock. Essentially, mailbox fishing is the art of fishing mail out of mailboxes and is quite a prolific criminal past time in some cities.

There are two options, the folding hook and hanger version or the sticky bottle version.

Take a wire coat hanger and open it up. Using the hanger hook, fish for the mail by forcing the mail against the hook or scooping it with the hook. Bring the envelope close to the door and then use your fingers to take it out.
The sticky bottle is basically adding a something sticky to the hook, such as s sponge attached with duct tape and having some exposed duct tape on the outside that sticks to the envelopes and brings them up.

These are time proven methods, and if they work for criminals, they will definitely work for honest people too.

What are mailboxes made of?

Post office boxes are controlled by the US Post Office guidelines. This means you can’t make your post office box any way you feel like. There are standards to conform to, so here goes:
US curbside mailboxes are classified as (T) Traditional, (C) Contemporary, or (L) Locking
Traditional or Contemporary non-locking curbside mailboxes are approved in three sizes:
No. 1, No. 2, or No. 3, these are measured by the minimum interior dimensions.

The largest curbside mailbox is the No. 3, and measures 22.81 inches long, 11 inches wide, and 15 inches in height (58 cm x 28 cm x 38 cm) at the peak.

Locking mailbox designs provide security for incoming mail and come with fewer restrictions on shape and size. The standard slot dimensions for incoming mail must be at least 1.75 inches high by 10 inches wide.

Residential locking mailboxes do not require the postal carrier to have a key as such; no USPS approved residential locking mailbox has secure outgoing mail.

The mailbox slot seizes standard basic dimensions, these vary between standard unlocked mailboxes to locking mailboxes. The incoming mail slot must be 41″-45″ above the roadside surface, and the front of the mailbox must be 6″-8″ back from the curb.

As for materials, the materials used must be metal or wood. Mailboxes secured on posts can be secured using concrete or dirt, and each state has its own specific regulations.
