OK this just got more interesting. The locked chests in the inn can be picked. The door in the currier cannot. The difference is that Tab shows the chests are interact-able items (highlighted in blue) whereas the one in the currier is not marked as such. The locked icon with the red keyhole shows up for it, though.

I'm currently experiencing the same thing too. The party stares dumbfounded at the doors in the tannery/cultist cave. Trying to put lockpicks in the quick item slot doesn't work. Double-clicking it does nothing. Unlike some of the other posters from above, I don't get any prompts about Mechanics. I also tried to lock bash but haha, nope. All in all though, wow, what a promising experience. I haven't been able to get any games for a long time but this... so far it's been like coming home :3
