I've never put any skill points into my lockpick because with enough tries i can get anything open eventually, until now. The locker containing the FOB simply WILL NOT unlock. Curious as to how much grinding for skill points i need to do before i can get into it, if anyone has any idea.

EDIT: Just recalled that there's explosives in one of the armory lockers in Navarro, might this work to open a locker? I will soon find out. Still curious about how high a lockpick should be though, i checked the fallout wiki site, which usually is absurdly specific and in depth, and even it says nothing.

Gamepedia says 70% Lockpick. You can also get it by persuasion (talk to everybody), and explosives.
