Don't rub too hard as this can damage the conductive paint and stop the button from firing when it is pressed.

Also, be sure to check the battery connector's terminals to ensure any loose solder connections. If this is the case, simply connecting them back may bring back function to the button. The same procedure can be used to restore function to any other loose connections in the fob.

Finally, if any of the buttons made of rubber that are on the front of the key fob stop working or require a difficult press to function it is likely that the graphite disks on the back of the button are wearing down and require replacement.
