Where to use the Door 3 Key. There are only 2 doors and 1 safe and 1 chest for unlock with the key. I unlock chest and 1 door. I don't know where to use the Door 3 key???
Yup it is you just need to open another door with door key 1 first, then it's a door in front of the door where you need door key 2, after that there is a third door where you need door key 3
