Palais Hansen Kempinski in Vienna – originally built as a hotel for the 1873 World Exhibition - is distinguished by its historic building, modern architecture, and modern luxury. The neorenaissance building is a listed historical structure located on Schottenring and is part of the famous Vienna grand boulevard Ringstrasse. The hotel is part of the Kempinski Group, one of Europe's oldest luxury hotel groups. Sterne Palais Hansen Kempinski Hotel chose a mechanical locking system from ASSA ABLOY to equip all the doors. With this grand-master key system, access authorisations are structured according to clear guidelines and requirements. This enables each employee to have a key for the hotel room of the corresponding work area while managers have keys to their departments and the hotel management holds the general master key for all doors.
