When I'm in someone else's theater, I actually prefer not having keys so long as it's not a huge pain in the
butt to get places I regularly need to get into. If the
venue has someone around to give me access as I may need it, I'm happy.
The exception being, I
really don't want to put things in fire doors to prop them open because a building is keyed weird. If something is keyed weird with crash bars that cannot be keyed open, then I'd rather have a key than prop a fire door open. Surprising how often people
base their normal operations on a holding a fire door open with a
stage weight...
