Thanks! Hopefully I will be able to figure it out when I reach Chapter 7.
Many of these kinds of locks in BG1 seem to serve no other purpose than to mystify you, particularly if they are on chests. I have used up tons of super-strength potions to break into some of the chests and such which are locked by "unconventional" locks only to find minor treasures or a couple of gold pieces. In BGII it does appear that most of them serve the purpose of keeping you out of an area or away from a certain item until you complete a quest, but in BGI they seem to very often be there for no reason.
