Replace Roland KF-90 keyboard felts

I have a Roland KF-90 digital piano that I’ve owned since 2001. Recently I have noticed that when I’m playing, that the keys on the lower and upper portions of the keyboard bounce quite a bit when released.

Is this due to the felt cushion strips wearing or drying out ?

I see that the felts are available through Syntaur. Is this a relatively easy fix to do ?

Thank you !
