15 year old Maple Tree is full of keys but very few leaves - it is end May. Is there something that I can do?

I just now understood you, you meant the seeds have stayed on the tree.
Wind, rain or the new leaves will push off the seeds.
Hardwoods are the last to fill out completely.
I understand your weather has been very cool. Eventually Mother Nature will warm it up!
