For the administration of cars in one corporation, most of the time secured and individually accessible key cabinets are used. Together with the customer Electric Time Car AS from Norway, we developed a cabinet where the handling of such a key-administration box is revised and simplified. Therefore, the mechanical parts didn’t have to be changed and central to this product was further developing the shell itself. An entirely new complexion was put on the initially “uninspired” box through minimal changes. On the one hand the front side now has a more gripping appearance, on the other hand the product improved ergonomically because the different functionalities such as usage (signal light, Schlüsselöffnung) and branding have been placed on different levels.
