The Best Locking Mailboxes for Security and Protection From the Elements

Hello, my friend, hello again; today we come together to talk about The Best Locking Mailboxes for Security and Protection From the Elements and hope the blog can help you.

Keep your mail safe from the elements and prying fingers with a locking mailbox for your home

A regular mailbox can’t deter a nosey neighbor or parcel thief, but a locking mailbox can. Mailboxes that lock typically have a slot that’s large enough to insert letters or parcels, and a locked portion that can be accessed for mail retrieval using a key. When deliveries are locked inside, the security of your packages is strengthened.

Locking mailboxes can be mounted on a wall at the front door or they can be mounted on a post in the yard. You may want a locking mailbox designed to accept packages, letters, or both. A locking mailbox for larger packages can be pricey, but it offers the ability to secure a larger variety of packages and deliver added peace of mind.

We interviewed security specialist Jeff Ketelaars, co-founder of Security Guards Only, an online community for security professionals, who provided his expert insight on how to properly deter package pirates. He suggests that “choosing the right locking mailbox for your needs will be effective at preventing mail theft as [it] mainly acts as a deterrent to potential thieves.” He goes on to say, “Although the design may not be 100 percent effective in preventing hacking, someone looking to steal mail will usually skip the locked boxes and try for an easier grab elsewhere.”
