Look for signs of corrosion or other indications that the buttons are worn out or damaged, like missing the conductive paint. Use a Q-tip, dipped in alcohol to gently clean any membrane contact that has become worn out or where conductive painting is missing. Do not rub too vigorously, as this could erode the conductive paint and prevent the button from firing when pressed.

Also, carefully check the battery connector's terminals to ensure any loose solder connections. If this is the case, reconnecting them may restore function to the button. The same process can be used to restore functionality to any other loose connections inside the fob.

If, for instance, any of the buttons made of rubber on the front of the key fob aren't working or require a very difficult press to function it is likely that the graphite disks at the back of the button are deteriorating and require replacement.

Non-Remote Transponder Chips

The sealed non-remote chips are more durable than remote fobs, however they are susceptible to breaking in the event of a hole being drilled in them, or if a car door handle or lawnmowers is pushed over them. Most of the time, non-remote transponder chips fail, and this can be blamed on blowing fuses.
