I have a problem with my Yamaha P-155

one of the keys require more force to the using. (work very hard)

Now when you press it. goes back very slowly (key change weight?)

I have a similar problem with another key but it is not so burdensome

Do you know what is the reason

The key is binding on something. Needs to go in for repair.
