10 Best Key Lock Boxes 2026 in the United States

The Master Lock Key Lock Box 5400EC5 is designed for secure outdoor storage of up to five standard house keys, making it a solid choice for realtors, landlords, and property managers who need quick yet safe access to properties. Its metal body combined with a vinyl-coated shackle offers good durability and helps prevent damage or scratching to door hardware. The four-digit combination lock lets you set and reset your own code, providing keyless convenience without the worry of lost keys or batteries. This lock box is weather-resistant thanks to a protective shutter covering the combination dials, which is important for outdoor use.

At about 6¼ inches tall and 3¼ inches wide, it’s compact enough to be portable but still large enough to hold multiple keys securely. The shackle fits most common door knob styles, allowing easy mounting on various doors or fixtures. One drawback is that it only holds up to five keys, which might be limiting if you have many keys to secure. Also, while it’s built for outdoor use, extreme weather or tampering could still pose challenges, so placement matters.

The package includes five lock boxes, which is great for managing several properties or sharing among a team. The product comes with a limited lifetime warranty, backing its reliability. If you want a straightforward, robust lock box with a customizable code system and reasonable capacity, this Master Lock is a dependable option.

The SentrySafe Fireproof Safe Box with Key Lock is designed to securely protect your valuables like documents, jewelry, and digital media from fire damage. Its steel construction combined with fire-resistant composites provides solid durability and fire protection, certified to withstand intense heat for up to 30 minutes. The key lock mechanism offers simple and direct security without complicated codes, including two keys for convenience.

With a capacity of 0.25 cubic feet, it’s compact enough to fit in small home spaces but still roomy enough for important papers and small valuables. The safe weighs about 17 pounds and has carrying grips, making it fairly portable, though not something you'd carry daily like a small lockbox. It mounts to the floor, which adds security but may limit flexibility in placement. One drawback is that it is not water-resistant, so it won’t protect against flooding or spills. The size is moderate—roughly 12 x 15 x 6 inches—so portability is decent, but it’s more suited for stationary use.

This safe presents a strong choice for those who prioritize fire protection and basic key-lock security in a small, durable package, especially in home environments where water exposure is minimal.

The Barska 600 Position Key Cabinet is a sturdy and practical choice for anyone needing to organize a large number of keys, especially in office or commercial settings. Made from alloy steel, it offers strong durability and security, which is important for protecting keys. The mechanical key lock provides reliable access control without the need for batteries or electronic components, making it simple to use and maintain. With space for up to 600 keys, it’s great for businesses or facilities with many users or rooms to manage.

The adjustable racks and colorful key tags make it easier to keep keys sorted and quickly identifiable, which reduces time spent searching for the right key. It mounts securely on the wall with included hardware, helping save floor space and keeping keys out of reach from unauthorized access. This cabinet is quite large and relatively heavy, so it’s not designed for portability or use outside of a fixed location. It also lacks weather resistance features, so it’s better suited for indoor use rather than outdoor environments.

Another limitation is the absence of a warranty, which might be a concern for some buyers. This key cabinet serves as a solid, no-frills option for organized key management in offices or businesses that need to store many keys securely and in one place.
