Roland MC-909 rubber buttons problem

Hello I have a problem with the Sequencer rubber buttons (Start, Stop, Rewind, Forward, Record) as they are very hard to make them operate. Did a small research and seems like they have a coat of graphene that could be refreshed and make them work again but I saw in your website that you have replacement rubber buttons:

I would like to verify that if I purchase this kit and replace my old buttons with the new ones from this set my problem will be solved. Thank you very much.
