I've come quite far with my Khajit Dar'Jo. Already level 47 and he decided to speak with this Brynjolf figure he met before he had his wedding. He joined the Thieves Guild and he got something else in return than just gold: an addiction to lockpicking. He's pretty good at it. Vex herself told him after he took a few lessons from her.

I've been picking so many locks. But I thought a bit ahead and now I have a question. It might sound like a question only a new one would ask.

Do locks reset? No even more specific(divided in 2 questions):

1st: Do friendly locks reset? Cities, villages and lonely cabins.
2nd: Do enemy locks reset? The ones in Nordic Ruins, bandit camps etc.

Thanks in advance!

P.S. I'm using Vanilla Skyrim(No DLC) on PS3.

Enemy locks like the ones in dungeons at least do reset but unless I'm mistaken, repicking the same lock grants zero experience.
