Made of durable metal, it features a four-digit combination lock that you can reset with thousands of possible codes for personalized security. Ideal for both indoor and outdoor use, the lock box is coated with vinyl to prevent scratches and includes a shutter door to protect the combination dials from weather elements.

The shackle is designed to fit most door knob styles, making it highly adaptable. Measuring 6.25 x 3.25 x 1.5 inches, it is relatively portable and can be conveniently mounted on a door or other surfaces. It should be noted that while the box is weather-resistant, it may not be fully waterproof, so placement in very wet conditions could be a concern.

The capacity, while adequate for most, is limited to five standard keys, which might not be enough for some users with larger key sets. Despite these minor drawbacks, the combination of durability, ease of use, and security makes it a solid choice for anyone in need of a reliable key storage solution, especially for outdoor use or real estate purposes.
