Then, using a Q-tip dipped in alcohol, gently clean any membrane contacts that have become worn or where conductive paint is missing. Do not rub too vigorously in order to damage the conductive paint, and block the button from firing when it is pressed.
Also, be sure to check the battery connector's terminals for a loose solder connection. If this is the case, connecting them back could bring back function to the button. You can use the same process to restore functionality to any other loose connection inside the fob.
