Hmm there are still a few lockpicking house that have all level of player locked chests in them in Atlantic, and the discord trick though cheap works awsome. Some ppl say you should not do that cause its cheating I disagre.
I made my first lockpicker the hard way, never again.
All I did was got to 95 picking chest that i saved while raising tink on a char, went to twisted weild and smacked a goat dude, ran out the sparkiels and back in the followed him around while picking the same gm chest over and over, took about 20 min.
