You can use Power Points to unlock locks--whoop! Starting with UNICEF Kid Power App v2.0 you can use the Power Points you earn as you get active to unlock the locks you run into on your various mission maps in the Kid Power App. The number of Power Points needed to unlock each lock varies--and if you don't have enough Power Points right when you get to the lock--don't worry! You can continue to wear your Kid Power Band, and get active, then come back to the Kid Power App to sync and all of your activity will show up in the Kid Power App. Once you earn enough Power Points, you can choose to use those Power Points to unlock the lock and you'll be on your away again!
Alternatively, you may purchase keys via in-app purchase to unlock locked waypoints immediately and save those Power Points for the next lock!
