Oh! I thought I was being a bit thick in my understanding. That makes sense. I thought he meant you didn't get advantage in situations where you can try again, which seemed like a really weird idea to me. Of course, I'm not sure I'd ever make anyone roll a check if they could just keep going and going. I'd just say "it takes you twenty minutes, but you get it done..." or something.
As a lock picking "expert" myself, I can assure you, a youtube video and two paperclips will let you open a standard padlock in 20 minutes. Faster if you are lucky.
With a sport lockpick set you get it done in a few minutes or with some luck in 6 seconds.
It has taken me a while to understand 3e in that regard: if there is no time pressure, just allow the rogue to always take 20 and suddenly DCs work right out of the book without magic items and the rogue feels good and useful.
