The Piloty-building is secured with electronic doorlocks. They can be opend using transponder. Transponder are small electronic devices, sending electronic signals if you click them. These signals can open the doors, if they are used in a short distance to the door. The door locks know which transponder is allowed to open which door. If a student gets a new transponder, the doors are programmed to open for this student.


To request for a transponder, please go to Transponder Request Form The ordered transponder can then be collected from room S2|02 - C119 (service center).

Normally students only get access to certain doors (e.g. in the E0-section of the Piloty-building). Additional doors can only be booked by authorized personnel (in most cases the secretariat).


There are several ways to return a transponder: One may return it in person at room S2|02 - C119 (service center), or drop it with bank details (name of the bank and IBAN) in an envelope in the letter box at karo5 or send it to:
