10 Best Outdoor Key Lock Box 2025 in the United States

The Master Lock Key Lock Box with Code is designed for outdoor use, making it a solid choice for realtors, property managers, and landlords who need safe, accessible key storage. Its metal body offers good durability, while the vinyl-coated shackle helps prevent scratches on door hardware. The lock uses a four-digit combination system, which you can easily set and reset to thousands of possible codes, so you don’t need keys to open it. This adds convenience and security. The lock box can hold up to five standard house keys, which suits most typical small key storage needs but might be tight if you have larger or more keys. It measures about 6¼ inches tall, 3¼ inches wide, and 1½ inches deep, so it’s compact enough to fit on many door knobs or mounting spots.

The built-in shutter door protects the combination dials from weather, helping it stand up to outdoor conditions, though it’s not rated for extreme weather or heavy rain. Mounting is freestanding or tabletop, which means you rely mostly on the shackle to attach it to a door knob; there’s no wall mounting hardware included. This might limit where you can place it depending on your setup. Setting the code and accessing keys is straightforward, making it user-friendly even for those not comfortable with technology.

The package includes two lock boxes, providing good value. While some users might prefer a larger capacity or more mounting flexibility, this product performs well for basic outdoor key security with easy access.

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.

The Master Lock Digital Lock Box for Keys is made of durable zinc material, which is robust and suitable for both indoor and outdoor use. It's equipped with an electronic locking mechanism and supports Bluetooth connection to iOS and Android apps, allowing for convenient code sharing. This feature is particularly useful for Airbnb hosts, vacation rental properties, and real estate agents who need to provide temporary or permanent access to different users. The lock box has a generous internal space, accommodating multiple keys or access cards with ease. It also includes a replaceable CR123A battery, which is already provided in the package.

The weather resistance capability down to -40° ensures that the contents remain protected under harsh conditions, making it a reliable choice for outdoor use. Additionally, it offers tamper and low-battery alerts for added security and convenience. The mounting process is straightforward with included hardware, though the size and weight of the unit may require careful placement to ensure secure installation. On the downside, reliance on a Bluetooth connection for some functionalities might be limiting for users who prefer non-digital solutions. The Master Lock Digital Lock Box provides a comprehensive solution for secure key management but might not be ideal for those who prefer simpler, non-electronic lock boxes.
