> But on three Onity locks installed on real hotel doors he and I tested at well-known independent and franchise hotels in New York, results were much more mixed
This is a long shot, but I was in a chain hotel in midtown recently and heard someone tampering with the lock, and found the door ajar in the morning. I realize you probably can't name specific hotels, but was one by any chance a chain hotel in midtown around the 11th?
I think the primary threat in this situation is burglary of an unoccupied hotel room.
Security chains are fairly easy to defeat; a bent clothes hanger will do. Deadbolts are probably pretty hard if there's no external key hole. Someone intending harm to the occupants of a hotel room might just break a window.
