Q. How does a key box work?

Answer

A key lockbox is a compact container typically mounted on a doorknob or the wall and roughly the size of an iPhone. The key is stored in a lockbox and can only be retrieved by entering a certain code. Key lockboxes like bicycle locks come in a broad variety of sizes and dial configurations. If users aren't going to be home when the guests arrive a lockbox or key safe is a good alternative. Programming push-button models is straightforward but passcodes are often predictable and easy to guess and experts can easily unlock most wheel models by tampering with the gears underneath them with a small metal object.
