Is the cover plate concealing a backup key lock? Call in the lock picking lawyer. Seems like many safes/locks don't stand up much to experienced attacks.
I am glad I wasn't the only person thinking about LPL for this. I wonder how much he would charge for a internet consult and recommendations on tools. Might end up being way less than the try-every-combination-or-we-drill-it locksmiths that are an hour awway
Since this is now somewhat famous, LPL will get a lot of views for opening this. As long as he can make a video about it, he should be able to do it free and turn a tidy profit.
Opens the lock after wiggling for 3 seconds… That's all I have for you today!
