How can I fix a keyboard with dead keys. ?

I have a Roland EM25 with a few keys that make no sound. Is this something I can fix myself?

Use your pinky finger
1.- stick it up your ass, so it get moist with shit
2.- rotate 6 or 7 times circular motion, also in and out
3.- Lubricate string of dead key with shit mix with saliba.
4.-suck on the top of the key until it became hot
5.-press down on key until you start burning yourself
6.- remove finger and stick up your ass again for burning relief.
7.- your piano is fix and ready to play.
