Some players' goal reads #/200 keys and others have the percentage but we can all only be gifted 20 keys each day which negates the counter.
Basically, the percentage or number of keys you have is irrelevant in the long run since we're just using them daily to craft chests. The overall point of the goal is to ask your neighbors for the keys each day so you can craft the chest(s) of your choice and get coins to help craft a wolf. The general run down is: Basic chest drops - wood and bronze coins, Deluxe Chest drops - bronze and silver coins, Premium Chest drops - Silver and Gold coins (I think someone even said they got a platinum coin).
Hope I explained that in a way that's understandable but really, this goal (or rather the event) has been a bit mad and confusing for most everyone playing.
