I feel it might be different depending on where you live, but in Japan&#x2F;France I always have a inside lock that prevents someone to unlock the door from the outside.<p>In Japan it was a door chain, in France you leave the key in the door and it blocks external keying. Also you&#x27;ll have to pass the building gates before reaching an appartment.<p>It&#x27;s not infailable, but it&#x27;s significantly more protected than any standard hotel room.<p>More than anything I remember unintentionally screwing hotel keys by having them with other devices, and the hotel front would reprint them pretty easily without asking anything more than the room number and the registered name.
