what yo doornob look like
Wait how did you lock yourself out
climb in thru a window. if that's not possible, try to push the lock open with something (a credit card you don't want, for example.)
with how the door is, you cant get a card to the lock
wait do you have one of those rooms with a door between rooms to the next one? you could use that
pick the lock
google how to pick a lock
you can use two paperclips as a lockpick, one to probe and the other as a torsion wrench.
if you have a ladder, you can climb in thru the window. if not, stuff dude u might have to kick your door down. here's a tip, aim for the area next to the lock, not the center of the door. kick straight out
