I know this has been brought up before, but searching doesn't bring anything up useful. As the topic suggests, the gate is locked. I have completed all the college quests and become the Archmage. As far as I know, this problem did not occur until I installed Dawnguard, as I had not visited in awhile prior to that, but was able to get access without fail when I was completing book finding quests. I have seen others suggest using the "unlock" console command on the gate and it opens for them. This never works for me. The gate always stays locked, and the only way to get in is to use the TCL command to clip through. The gate cannot be unlocked from the inside either. Is there a fix in the works for this? Even just a key would be terrific.
