Overview of Locking Mailboxes
With identity thieves and porch pirates becoming more brazen, homeowners want to know their mail and packages will be secure from the time they’re delivered until they can be retrieved, without having to put a combination lock or padlock on their current mailbox. That’s why locking mailboxes, also called secure mailboxes, are trending among security-conscious homeowners who are often replacing standard or brick mailboxes to replace with a secure mailbox.
Securing your mail is just as important as having a strong lock on your entry doors. Mailboxes on posts near the road remain the norm in most neighborhoods in the United states, but wall-mounted mailboxes near front doors are growing in popularity as more homeowners consider security for their mail. Homeowners feel they are more secure and can be installed on a porch or garage in view of a security camera. Your options also include a few high security free-standing curbside locking mailboxes, usually with steel pedestals, which are among the most expensive models.
This cost estimate for a locking mailbox covers cost factors such as size, type and material, and how they impact price. Retail costs for boxes and installation materials are listed plus the installation labor cost to have the work done professionally. These are single-family mailboxes.
Costs from top estimating sites are included plus prices submitted by homeowners. You’re invited to share your cost, whether you install the mailbox yourself or hire a contractor to do it.

Locking Mailbox Price Factors
Before we get to pricing, here is a look at your range of options available in residential locking mailboxes and how they affect cost.
- Size – Typically, the larger the mailbox, when other factors are the same, the more it will cost.
- Type – Mailboxes on posts have a higher total price than wall mailboxes due to higher material and installation costs. Free-standing pedestal mailboxes that sit on a footing or a porch are usually high-end, costly units.
- Style – There are plenty of options to fit well with your home’s architectural style, from classic and antique to contemporary with modern styling. Those with more elaborate styling such as stamped metal or wrought iron components tend to cost more.
- Material and Construction — Most are steel, though there are a few plastic resin models. Cheap locking mailboxes are thin steel. Those that cost more are made from high-impact steel of a thicker gauge. Copper locking mailboxes are stylish, but keep in mind that copper is a softer metal than steel. Boxes with welded seams are tougher and cost more than those with folded or crimped seams.
- Security Features – Advanced security features can add to the cost of a locking mailbox. Heavy duty anti-pry locking mechanisms and spring-loaded, push-in doors that hinder attempts to fish out mail are among the security features to consider as you shop for and compare secure mailbox costs.
- Accessories – For mailboxes on posts, your options include wood or steel posts, sheaths to cover wood posts or even house the entire box. The cost of the accessories can affect cost by up to 33%. There are few accessories for wall-mounted mailboxes.
- DIY vs Hiring the Installation – Labor costs for a handyman are discussed below, so you can see potential savings of DIY.
Locking Mailbox Sizes and What They Hold
Locking mailboxes start small, sized for envelopes, newspapers and small parcels.
Mid-size secure mailboxes can accommodate a shoe box-size parcel.
The largest are big enough for a couple shoe boxes or a 12-inch cube package. Many large locking mailboxes have an upper chamber for general mail and a lower chamber for packages.
These extra-large models are also called architectural mailboxes and mail vaults. Secure wall mailboxes tend to be taller with less front-to-back depth than those that fit on a traditional mailbox post. The largest post-mounted units have more internal capacity than the largest wall-mounted lockable mailboxes.

DIY or Hire a Pro?
It’s your call, based on your skill level and time.
Installing either type is an easy to moderate DIY job. Most homeowners save $80 to $125 by doing the work.
The most important step is to make sure the installation fits US Postal Service regulations. This USPS page includes information about mailbox size, construction, placement from the road, height and more.

Post-mounted mailboxes usually don’t have instructions, at least not for the entire job. There are many how-to videos like this one available.
Any locking wall mailbox you buy should include thorough installation instructions. Video tutorials for that job are available too.
In our opinion, if you have the time, then locking mailbox installation is a DIY project you will like succeed with.
