어야 들어가다

must X to get in

A condition that has to be satisfied before you can enter. Most of these lines are access control: you have to scan a student card, you need a pass, you have to hand over your passport, you have to go through a check. Others are about physically fitting: it only goes in diagonally, we would have to break my ribs to make room, does it only fit if this bit sticks out.
