Do-It-Yourself 

Permanently repairs rubber keypad buttons by replacing the conductive material.

Your buttons fails when the conductive pad wears out and silicone oils seep from the keypad. This gooey paste blocks electrical conductivity and stops the switch from working. 
The ButtonWorx membrane keypad blocks dirt and oil from reaching the circuit board and offers a new conductor that cannot break down like rubber conductors do.
