The building uses Häfele's customized master key locking system. A master key can control 8000 door locks in the building and realize the grading rights control of multiple groups/domains.

Häfele master key locking systems are used for organization in large office buildings with several departments and sub-departments. For example, GMK systems have both individual keys (IK) and group keys (GK) that are assigned to different IK's. Several GK can be assigned to one master group key (MGK). The general master key (GMK) then overrides every key in the system.
