Use a Q-tip dipped into rubbing alcohol to gently clean any membrane contact that is worn-out or has conductive paint missing. Do not rub too vigorously, as this could erode the conductive paint and prevent the button from firing when it is pressed.

Examine the battery connector's terminals carefully for near any loose solder connections. Soldering them back into place will allow the button to function again If this is the situation. The same procedure can be used to restore function to any loose connections in the fob.

If any of the rubber buttons on the front of the keyfob are not working or require being pressing very hard the graphite disks on the back of the button might have worn out and require replacement. This can be done by rubbing a pencil over the disks, which will bring the button back to working.

Most of the time, non-remote transponder chip malfunctions can be blamed on a blown fuse.
