I was screwing around with the odd thought that "You know, Freddy is kinda like power armor from Fallout 4". Turns out that that... halfway was true. I was trying to get through the wall initially into mazercise, and at one of the attempts, he opened up the door. The door barrier is still physically there, but another attempt from the corner of the open door facing inwards actually pushed me through the barrier into mazercise without needing the pass to open it.

I should explain better on how I did it. Shove freddy's back against the corner of the door. Get out facing away. Door "should" open. Get back in Freddy. Face towards the inside of the room while still in the corner. If you hop out towards the room, the animation of you walking forwards slightly should push you through the barrier and into the room.

I can't seem to do it again, but the possibility is there if something reliable can be found. This could skip past any standard door that isn't a shutter in my thought.
