A new video shows just how easy it can be to pick a locked hotel room door using just a 'Do Not Disturb' sign. 

One of the LockPickingLawyer's latest videos features the real-life Washington, DC-area attorney revealing that he managed to pick the doors to his locked hotel suite in less than two seconds. 

The 30-something man starts the quick clip by saying that he and his wife had checking into a hotel suite over New Year's, when he noticed that their double doors weren't installed properly.
