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 into rubbing alcohol to gently clean any membrane contact that has damaged or where conductive painting is missing. Don't rub too hard as this can damage the conductive paint and stop the button from firing when it is pressed.

Also, carefully check the battery connector's terminals for an unattached solder connection. Soldering them back in place will allow the button to function again if this is the situation. The same method can be used to restore function to any other loose connections in the fob.

If, for instance, any of the rubber buttons on the front of the key fob stop functioning or require a difficult press to function, it is likely that the graphite disks on the back of the button are deteriorating and require replacement. This can usually be done by rubbing a pencil over the disks. This should bring the button back to its original state.

Non-Remote Transponder Chips

The non-remote chips sealed in a sealed case are more durable than their remote fobs, but they are susceptible to breaking if a hole is drilled in them, or when a door handle for a car or lawnmowers is pushed over them. Fuse failures are usually the cause of non-remote chip failures.
