Look for signs of corrosion or other indications that the buttons are worn or damaged, like missing the conductive paint. Utilizing a Q-tip that has been dipped in rubbing alcohol, gently clean any membrane contacts that have become damaged or have conductive paint missing. Do not rub too vigorously as this can damage the conductive paint and prevent the button from firing when it is pressed.
Examine the battery connector's terminals for loose solder connections. Soldering them back into place will allow the button to function again If this is the case. The same method can be used to restore functionality to any other loose connections within the fob.
In the end, if any of the rubber buttons on the front of the key fob have stopped working or require a hard press to work it is likely the graphite disks on the back of the button are wearing down and need to be replaced.

Soldering terminals and buttons back to their original positions is often enough to return a malfunctioning fob to working.
Non-Remote transponder chips
The non-remote chips that are sealed are more durable than remote fobs.
