First, check that the batteries are properly installed and that the indentation at the back of the button has been filled. Then, carefully open the remote and look at the circuit board. Look for indications of rust or other signs the buttons are worn or damaged. For instance the paint that conducts electricity could be missing. Use a Q-tip that has been dipped in alcohol to gently clean any membrane contact that is damaged or where conductive paint is missing. Do not rub too vigorously as this can damage the conductive paint and prevent the button from firing when it is pressed.
Check the battery connector terminals carefully for any loose solder connections. Soldering them back in place will allow the button to function again If this is the situation. The same process can be used to restore function to any loose connections in the fob.
If, for instance, any of the buttons made of rubber that are on the front of the key fob aren't working or require a difficult press to function, it is likely that the graphite disks at the back of the button are wearing down and require replacement. You can usually do this by rubbing a pen across the disks. This should bring the button back to life.

If you're handy enough to open your
repair key fob fob and aren't afraid of a little mess, we can de-solder the buttons and then solder new ones in their place. Also, you should check the connections between battery terminals. If they're loose, the buttons may not work or even become stuck in their down position. Soldering the terminals back to their original positions is often enough to bring a non-working fob back to working.
Non-Remote Transponder Chips
Sealed non-remote transponder chips are more durable than remote fobs that have them but they can still be damaged by a hole that is made in them or pushed over by a lawnmowers or
repair car key fob door handle. Most of the time, non-remote transponder chip failures can be blamed on blowing fuses.
If you're handy enough to open up a key fob that is sealed and can tolerate the mess, you can easily remove the circuit board and examine the fuse with a multimeter to ensure that it is functioning as intended. function. If you're not comfortable with this, visit your local Oreilly or hardware store and use their RF frequency tester. This will let you know whether the key fob is sending signals.
