Residence Hall Access

Upon check-in, residents receive a key to their room/mailbox. Duplication of any University keys, including room keys, is prohibited by the code of conduct. For security reasons, it is recommended that students not carry their University ID together with their room key in the event of loss. Loss of keys and University ONEcard identification should be reported immediately to Residence Life & Housing staff or the University of Delaware Police Department.

Lost University ONEcard

Students should use their University provided ONEcard identification to access their residence hall building. Students who lose their ONEcard identification may sign out a spare access card from the Residence Life & Housing staff office, which must be returned within five (5) business days or the student will be charged $25.00 for a replacement spare card. Students can obtain a new ONEcard identification by visiting the ONEcard Office in the Student Services building on Lovett Ave. To disable a lost ONEcard identification, please visit

Lost Keys

Students who lose or misplace their key may sign out a spare key from Residence Life & Housing staff, which must be returned within 48 hours. For personal safety, when keys and identification are lost together, an emergency lock core change must be initiated. Students should contact Residence Life & Housing staff or University Police to initiate this lock core change. Students who do not return their key within 48 hours or need an emergency core change will receive a charge to their student account from Facilities.


Students must return room keys to the Residence Life & Housing staff at the end of fall, winter and spring semesters or if they move out of their residence hall room during the semester. For security reasons, if keys are not returned within the required time frame, locks on doors are changed, and residents are billed accordingly. Students should keep their ONEcard though breaks and, if lost, will be required to purchase a new card.

Spare Keys

Repetitive use of spare keys is an unsafe practice. Any student who checks out more than four spares a semester may face student conduct action.
