Thanks again puslar123!! I had to scrounge like 4 more YouTube videos to figure it out , but was able to fix my PX-130 with the same issue.

For everyone else, here's a quick summary of the steps:

1) Remove wing screws to remove lift piano
2) remove bottom screws
remove cross bar, then cross bar holders
3) remove black side screws (3 on each side)
4) remove outer panel on each side
5) remove 5 screws on inner panel each side
6) remove inner panel
7) lift electronics board - disconnect 2 ribbons
8 ) remove 3 screws holding white frame with the keys
9) lift frame
10) unhinge each key (white first, then black because white holding in the blacks)
can push hammer past felt 
no need to remove each key
11) once all the keys are “un-hammered”, can access the green PCB board
12) remove small black screws on PCB
can lay plastic wrap on white frame to protect from the grease
13) lift green PCB board and place somewhere safely
14) remove the screws holding the tan PCB board
can remove ribbon here - this one is harder to put back in
15) lift the PCB board and access the “velocity” rubber pads
need 7 full pads + 4 for complete replacement. just get 8 for safety
16) replace the pads - they are directional so you must put them in the same direction or they will play at full volume
17) replace tan PCB board, replace screws
replace ribbon
18) etc.
19) can test keys before reinstalling case
20) re-install white frame, electronics panel, inner panels, outer panels, then rescrew the bottom
