I'm really enjoying this game but I'm pulling my hair out on the lock picking puzzle. Even with the solution I can't get it.

It's been a long time since I played Still Life, but I do remember that puzzle, but try the link for a good Walkthrough (there is a solution to that puzzle with a picture), anyway, the puzzle certainly isn't impossible to solve, but if the walkthrough doesn't help, then stop playing the game for a day and then return with a clear mind.

That is the best advice I can give you, good luck :-)
