This can be extremely frustrating particularly if you're out of town and need to start your vehicle. Even worn-out or malfunctioning buttons are often fixable with a bit of time and tools you already have at home.

First, make sure the batteries are properly charged and that the indentation on the back of the button is filled. Take the remote apart and inspect the circuit board. Look for signs of corrosion or other signs that the buttons are worn out or damaged, such as missing conductive paint. Then, using a Q-tip dipped in alcohol to gently clean any membrane contacts that are damaged or have conductive paint missing. Be careful not to rub too hard, since this could cause damage to the conductive painting and prevent the button from firing when it is pressed.

Check the battery connector terminals for loose solder connections. If this is the case, connecting them back could bring back function to the button. The same method can be used to restore functionality to any other loose connections inside the fob.

If you are not comfortable opening the key fob, remove the circuitboard and utilize a multimeter to check that the diode is working properly. If you're not sure with this, go to your local Oreilly or hardware store and use their RF frequency tester. This will let you know whether the key fob sends a signal.
