Q: Do I need to get approval before I submit a key order?

All others listed are authorized to sign for individual room keys within their DLC.

Q: How do I know when the keys are ready?

A: The Key Authorizer in your DLC will receive an email from SEMO notifying him/her when the keys are ready. If you were not included in the email notification, your Key Authorizer will then notify you that you that you can now go to the Customer Service Center to pick them up.

A: The Customer Service Center in Room 7-019, weekdays, 8 a.m. to 4 p.m.
