  > Without the lock button you could hit the "close door" button and leave the toilet while it is closing, and then no-one would be able to enter to unlock it. According to the article, you can do that anyway. “you can close the door, then hold the lever just beyond the point at which the locking pin could engage with it, but not to the point where it reads as “locked”. Then you can open the door, but the locking pin projects into thin air; thus the lever is free and can be moved to the locked position. The door close button remains active and you can then close the door. I confirmed that the door will then immediately lock as soon as the door is closed. Since I could do this and then jump out before the door closes, this is effectively a toilet DoS vulnerability on a train.”
