There is a way to cheat to get enough gold to learn Lockpick (ie from Keith in the BF or from the imp Tax) and the skill points to put into it, but I never tried to see if the maximum level could be edited.
Hex editing - gold, experience, stat/skill pointsHowever, since doors are your main concern, Lockpick isn't nearly as important as finding the required key or lever. I can only think of a couple doors/chests that you need Lockpick to be able to open, and they only contain minor random loot. In addition to the maps Lady Rain mentioned (
or these), you could also skim through the
Beyond Divinity Strategy Guide if you have explored an area but a door or chest remains locked. There are a couple chests where finding the key is a little elaborate, or you need to reach another area first.
