10 Best Outdoor Key Lock Box 2025 in the United States

The Puroma Key Lock Box is primarily made of high-quality aluminum alloy and steel, which makes it robust and resistant to rust, cutting, and other forms of damage. This ensures that your keys are kept secure. It features a mechanical combination lock that you can reset with a custom 4-digit code, offering up to 10,000 possible combinations, which adds a high level of security. The initial code is set to 0-0-0-0, making it easy to reprogram to your desired combination.

The box's dimensions are 1.54 inches in depth, 3.07 inches in width, and 5.75 inches in height, providing ample space for storing multiple keys. This makes it particularly useful for homeowners, office workers, or even Airbnb hosts who need to share keys securely. It is designed to be weather-resistant, so it can withstand outdoor conditions, although the extent of its water resistance is not specified in detail.

The lockbox offers versatile mounting options; it can be hung on a doorknob using the removable shackle or securely mounted to a wall with the provided screws and expansion plugs. Users have found it relatively easy to set up and use, appreciating its large capacity and sturdy build. However, it’s worth noting that while it is weather-resistant, it may not be fully waterproof, so ensuring it’s placed in a sheltered location could be prudent. Additionally, while the combination lock mechanism is generally reliable, it requires careful handling to ensure longevity. With a weight of just 0.6 pounds, it is lightweight and portable. This product is well-suited for anyone needing a secure key storage solution, particularly in environments where multiple people need access to keys, like rentals or offices.

The Rudy Run Outdoor Key Lock Box is a solid choice for anyone needing a secure place to store spare keys outside, whether at home, an Airbnb, or an office. It’s made from rust-resistant aluminum alloy and stainless steel, so it can hold up well against weather and physical tampering like hammering or prying. This makes it a reliable option if you want peace of mind that your keys will stay safe. The 4-digit combination lock is adjustable with up to 10,000 code possibilities, which adds a good level of security and eliminates the need for keys to open the box itself. A protective cover shields the dials from dust and rain, enhancing its weather resistance.

With a capacity to hold at least five keys plus small items like credit cards or USB drives, it offers a bit more space than many basic lock boxes, though it’s still compact at roughly 4.5 by 3.7 inches, so it won’t fit larger items. Installation is straightforward with included screws and plugs for wall mounting, and the instructions are clear for setting your own code and mounting securely. While the box is rated water resistant rather than waterproof, it should withstand typical outdoor conditions without problems. One thing to consider is its weight limit of about one pound, which suits keys and a few small objects but may be too small for bulkier contents.

This lock box delivers a combination of durability, ease of use, and flexible mounting options, making it a practical pick for outdoor key storage when a very large container is not required.

One of the standout features is the lifetime warranty, offering peace of mind for your investment. On the downside, the 1.63-pound weight might be a bit heavy for some users, and the mechanical code lock may not be as convenient as electronic options. Additionally, while the black color is sleek and discreet, some users might prefer more color options to match their exterior decor. Nonetheless, the Iron Lock® XXL Key Lock Box is a reliable choice for those needing a secure, weather-resistant key storage solution.
