I got #2, and I have a solution for #1, but I don't think it's right. Here's my non-right solution to #1:
G places the amulet in his own safe, locks it with the padlock, and keeps the key. G sends the safe to K by way of a servant. K takes the safe with him and uses whatever tools to open it at his convenience once he is safe away.
I think this is wrong, because it's not very satisfying at all. I think it could be right, because (1) it could work in real life and (2) it meets the solution criteria of the puzzle, namely, transferring the amulet from G to K.
I would be happy to know of a more elegant solution.
