A Padfoot potion might help if you’re trying to get over a hurdle. FWIW I play solely on Xbox and over time my lockpicking experience as a player has gone from massively frustrating to routine. I think there is a real learning curve as a player and part of the genius of the game is how the player’s proficiency gains blend with Henry’s level gains to create a uniquely immersive experience.
One unavoidable downside is you don’t get to experience that blend every playthrough: once you’ve mastered the player skills you’ll be unlocking chests Henry ought to be completely baffled by, so enjoy it while it lasts.
