Office keys are issued under the agreement that the holder will reimburse the Department of Computer Science $50 upon failure to return any key(s) issued to them. The Department of Computer Science will bill the student account at University of Chicago for the loss. Lost keys will be replaced at a cost of $30 per loss. The replacement fee must be paid in cash or check prior to the key being re-issued. Excessive requests for replacement keys may result in the need to replace the room core or multiple cores. Many department keys have multiple layer access such as unlocking main doors in addition to individual offices. Lost keys compromise the security of the entire building not just the office to which they are issued. The cost of these re-cores will be the responsibility of the keyholder.
Keys are to be returned to Donna Brooms. To return keys after hours, place the key in an envelope, write your name on the outside and slide it under the door to Room 212.
