An interesting video posted by a YouTube that has quickly attracted over a million views, infers that many hotel safes shouldn't be trusted.
Like in the video's example, hotel in-room safes may be easily accessed by entering the original default factory code if this has not been reset by the hotel when it was first installed in the room.
The video shows a guest unlocking a hotel safe by entering one example of a default factory code being all zeros (all 1s are apparently another example).
This video is a call-to-action for all hotels and motels if their in-room safes have a factory code, to ensure that this is reset to avoid negligence claims from guests.
