The typical locking mailbox kit includes: the box itself (although it might be in several pieces, depending on the type and style of the mailbox), a post with an end cap, a brace, a number plaque and tags for applying an address, a flag for mail delivery, a door with hinges, a back panel, some decorative parts (again, depending on the style), a base and, finally, a lock-and-key set, the last of which distinguishes locking mailboxes from open mailboxes. Most mailboxes nowadays likely include the lock-and-ket set for necessary security. If owners wish not to use them, they simple to not include them in the assembly.

Lock-and-key sets are also available separately for those who already have an open mailbox. They are easy to insert and secure with a drill and screwdriver. Still, instructions provide a helpful guide and offer a variety of tips for first-time users.

Those seeking an ideal mailbox, especially if it is curbside, are strongly advised to purchase locking mailbox kits. Having a lock on one’s mailbox is no small matter; the security of one’s mail should be considered of utmost sanctity and importance.
