Yes. It is easy. I replaced mine just before this season.
The button is located in a plastic housing that has a tab on the top. On the bottom is a small slot that will take a screwdriver blade. Insert the blade into that slot and slowly turn. The housing will pop off.
Remove the old cover, insert the new cover, put the upper part of the housing in first, then tap it with your hand til it clicks in place.
Literally 2 minutes.
