I have been putting on cart and mining to find the chest.
start digging around it until you find it start coming up and then run away. this will leave a dirt batch or possibly just drop something there to mark the spot.
the go home and take off both cart and mining and put on what skills you need. at least this way you only lockpicking on and have room again for your skills.
it seems you have to have cart on now to open the map regardless if you decoded it already.
