We put our BBB in twin beds. The monitor went out in the hall. The only thing left in their room was a dresser bolted to the wall with small tv & dvd player on top of it. Closet doors were locked like yours (but be ready for the clothes to come out of any dresser for awhile). We put a gate on the door to their room & after potty trained at night moved it top of stairs. Eventually the newness wears off & it calms down (watching movies helped), but it was crazy for awhile. Lots of walking up & downstairs threatening & begging. Good luck...
