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 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.

The RUDY RUN Key Lock Box is designed to safely store multiple keys or small valuables outdoors. Made from rust-resistant aluminum alloy and sturdy stainless steel, it offers strong protection against weather and physical tampering like hammering or sawing. Its size is compact but roomy enough to hold at least five keys along with other small items like key fobs or USB drives, making it suitable for home, vacation properties, or workplaces.

The lock uses a 4-digit combination that you can easily set yourself, allowing for 10,000 possible codes, with a protective cover to shield the dial from dust and rain. Installing the box is straightforward since it comes with screws, nylon plugs, and clear instructions for mounting on walls or other hard surfaces. Weighing about a pound, it is durable yet not overly bulky. Users praise its solid build and reliable locking mechanism, reflected in high ratings.

While the combination lock is secure, those unfamiliar with setting it might need to carefully follow instructions at first. Also, since it is wall-mounted, it requires drilling into a suitable surface, which might not fit every location. This lock box provides a practical, weather-resistant, and easy-to-use solution for securely sharing access to your keys outdoors.
