The seller did contact me pretty quickly last night, but I did get it solved before that with an internet search and some trial and error.? The internet told me that the default Baofeng password is 000000, the trial and error was that you need to hit the menu button after typing in the password.
The power on resets I found online didn't work with this model.
So, if you get a used Baofeng with a password on it, try 000000 MENU to see if that unlocks.
I would never have a reason to password protect my Baofeng but I suppose some others might have need to.
