Contrary to popular nerd belief... door locks in the US are not that easy to pick. Many have anti pick features like reverse sidebars that while not impenetrable increase time or skill required. While the lockpickinglawyer has videos, note that he is extremely skilled with tons of practice, it still can take more time than breaking, and those aren’t field conditions. Just break the door in... stealing might as well use forcible entry.

Where picking is useful is covert spying, and if that is your threat model the addition of the second or third lock doesn’t really mean much.
