In order to finish the event you have to collect enough hidden keys to open all the chests. Other wise you will finish the quest and ge the avatars but you won't be able to finish the event and go for the big prize of the extra chest that apear after that and needs aditional 1000 keys to be open.

And that extra chest have a big prize of artifact assemblers, three of each kind plus other usefull stuf. I never fail to finish an event without spending money for diamonds, and the only time that I was not able to open the extra chest was last event when I was away for most of the month. Usually I need 10 days to finish an event but I'm high level player so for lower level players the time day need might be different.
