Up to eight keys. Our Mini Key Box KeyGarage™ 727 can be mounted on the wall and holds up to eight keys. You can protect your keys and smaller valuables from unauthorized access with this compact KeyGarage™. The key box features a sturdy metal housing and a zinc die-cast closure flap, and it can be mounted on the wall. It can only be opened by individuals to whom you have shared the four-digit code. Inside, there is space for eight keys. You can also store other small items, such as USB sticks, there. We recommend installing the KeyGarage™ 727 Mini in a sheltered outdoor area.
