I would recommand that you get 3-5 friends together and do Mission 2-3 from your home towns while you go around getting keys sense you'll be going to the same zones. When I had to get the keys I just made a day out of it and spent time with friends. Just stick with people from two of the towns and do the town you have nobody from last.
