Maintenance providers and emergency services are authorized to open the wall key deposit with the unique maintenance key of the building. They use the entrance key to gain access to the building and perform the intended maintenance or carry out emergency operations. Afterwards, the building is locked and the maintenance key is returned to the wall key deposit.


To prevent vandalism, the wall key deposit should be installed in a concrete wall of quality K250 or higher. Install at least 1,500 mm above ground level.

The wall key deposit must incorporate an approved ASSA high-security cylinder where the keys have a minimum key control level of SELECTED to ensure protection against unauthorised copying.
