After starting work, you must collect your electronic office key (transponder) either from your relevant secretariat or, after making an appointment, from the departmental administration office of the Department of Political and Social Sciences: 

Department of Political and Social Sciences 
Key issues 
Ihnestr. 21, 14195 Berlin
Room210
Email: schluessel@polsoz.fu-berlin.de
Homepage: https://www.polsoz.fu-berlin.de/verwaltung/schluessel/index.html

Office hours: Monday, Tuesday, Wednesday: 9:00 a.m. to 12:00 p.m. 

The locking authorizations on the transponders can be changed at any time if necessary after consultation with your supervisor and the responsible secretariat. 

Important: 

• The transponders must be updated at the latest after 7 days at the so-called master reader on the ground floor of Garystr. 55 (to the right of the entrance door to the stairwell) in order to continue to be able to open doors. 
• The transponders only lock from Monday to Friday during normal working hours (7:00 a.m. to 10:00 p.m.), but not at night, on Saturdays, Sundays or public holidays!
• Only professors and security officers can apply for unlimited round-the-clock access. 
• If academic or other staff members need to be at the institute outside the above-mentioned hours for work-related reasons, e.g., if they are holding block seminars, workshops, or meetings on weekends, they can submit a special form to apply for temporary “access authorization outside building opening hours.” The application must be digitally countersigned by the applicant and their supervisor and sent as an email attachment to the department's key department.
• If you lose your locking transponder, please contact your responsible secretariat or the department administration immediately to have your transponder blocked.
