Siebel Center Hours and E-Lock Requests

Almost all of the doors in Siebel Center, including the outside entrance doors, are controlled by e-locks and require access on your i-card to gain entry. 

Undergraduate students who are Computer Science majors can request e-lock access via go.illinois.edu/elock.

If you have an issue accessing an area or need to request access to a specific area, you may submit a ticket to space@cs.illinois.edu 

If you have a request to gain access to a specific area and/or you recently replaced your I-Card, you can submit your request via go.illinois.edu/elock.

Your request may be processed faster if your supervisor directly approves and submits the request on your behalf.
