Tips: 

If you are not having trouble with the snap dome keys Don't Repair Them
Volume, Channel, Play, Pause, Arrows and OK
If you are having trouble then I recommend Deoxit GOLD G100L (available as an optional add-on). You could also use Isopropyl alcohol. 

If you don't often use the number buttons at the bottom of the remote, don't worry about them. Just install the repair pad
If you DO use the number buttons or if you are already having trouble with those buttons, then I recommend peeling back and cutting the bottom of the white sticker found on the circuit board and attaching it to the top of the repair pad. This makes a significant difference in how easily those buttons respond to a light button press.
