I suspect she says "use" to mean "equip". You don't need to equip it, merely have it in your inventory. Then select the character that has it, select "Use/Give Item" (the Use option) and page through the list showing in the bottom left until the Bauble Stick is showing. This allows you to use the item in the Main Game Screen by left-clicking. Then just mouse over the Crystal Key and left-click. You cannot reach the Gold Key at this point, so don't bother drowning to try.
