What am I supposed to do in the toy warehouse I find a key then what leave? where are the circuits so I can get money?
The key is for the next area I believe which is at the end of the zone your in when exploring the warehouse, and the game tells you that the circuits you can get from defeating the toys or from the presents that are laid out randomly through each level. (But take this with a grain of salt since last time I played this is when it last updated 3 months ago).
