Mechanical Kaba key depots and key tubes

Mechanical key depots provide a means of separating lock groups in buildings or organizations, thus increasing security. Through the centralized collection of personal keys, a key which has been assigned to another group can be picked up at any time – the user's personal key remains captive until the other key is returned, thus ensuring that the user's personal key can be released.

• Hotels, for safekeeping of room keys
• Separating external and internal locks in large building complexes
• Connecting various locking groups in buildings with different uses (e.g. cleaning staff)
