A key safe lock box is a simple and basic storage device, designed to be attached to a wall which can be used to securely and safely contain keys that you might need to share with another person. For example, house, car or garage keys that need to be accessed by a third party such as a realtor, cleaner or someone letting out a room in your home or your sharing access to your vehicle temporarily. They come in a range of sizes, shapes, and materials and are usually operated wither via a combination of push-button locks, a scrolling wheel mechanism or perhaps a rotating dial with a pre-agreed combination.
