About this product
This large key box from Master Lock offers secure storage for keys, suitable for indoor or outdoor use. It is unlocked via Bluetooth using a free smartphone or tablet app (available for Apple and Android), making it suited to tradespeople, contractors and property managers who need to manage access to a site or premises. Access can be shared with others either permanently or for one-time use, and the box keeps a record of all access history for monitoring purposes. A low battery reminder gives advance warning before power runs out, and a backup numeric keypad allows entry when a Bluetooth connection isn't available. The key box is supplied with a CR123 battery.
