University of Delaware

Residence Hall Access

Upon check-in, you will receive a key to your room/mailbox. Duplication of any University keys, including room keys, is prohibited by the code of conduct. For security reasons, we recommend that you not carry your University ID card (ONEcard) together with your 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

You should use your University-provided ONEcard identification to access your residence hall building.

If you lose your ONEcard identification, you can sign out a spare access card from the Residence Life & Housing staff office. Spare access cards must be returned within five (5) business days or you will be charged $25.00 for a replacement spare card.

You can get a new ONEcard by visiting the ONEcard Office in the Student Services building on Lovett Ave. To disable a lost ONEcard identification, please visit

Lost Keys

If you lose or misplace your key, you can 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 may be initiated.

Please contact Residence Life & Housing staff or University Police if you want to initiate this lock core change. If you do not return your key within 48 hours or need an emergency core change, your student account will be charged by Facilities.


You must return your room key to the Residence Life & Housing staff in your building at the end of fall, winter and spring semesters or if you move out of your residence hall room during the semester.

For security reasons, if you do not return your key within the required time frame, the lock on your door is changed, and you will be billed accordingly. You should keep your ONEcard through breaks. If you lose your ONEcard, you 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.
