How Our Locking Mailbox Insert Works

Our mailbox insert comes with a 5-pin heavy duty polished brass lock. Each lock is unique - these locks do not repeat. You will receive 2 keys with your order and may purchase extra for $1.00 each. These inserts are powder coated black and come with easy-to-follow instructions as well as hardware for mounting. Installation takes only a few minutes.

Our locking mailbox insert provides protection against prying hands and against having your mail stolen. The insert can hold:

  • Bills
  • Letters
  • Magazines
  • DVDs
  • CDs
  • and more.

Do I need a New Mailbox?

You can purchase our insert with a new mailbox that we offer, or you may use your existing mailbox. Our mailboxes come in black and white and are ready to be used with your new mailbox insert.

If you use your existing mailbox, it's important that you measure the mailbox to make sure the insert will fit and that the flag mount does not interfere. You should also call your local post office, or talk to your local carrier and make sure the lockable insert is acceptable in your area. Most carriers are willing to work with home owners as long as the volume of mail received doesn’t exceed the dimensions of the incoming slot on a regular basis. If you have any questions, please call us at 1-800-963-6335.
