Even worn-out or malfunctioning buttons are often fixable with a little effort and the tools you already have at home.

First, verify that the batteries are properly inserted and that the indentation on the back of the button is filled. Then, open the remote with care and look over the circuit board. Examine for indications of rust or other signs the buttons have been damaged or worn. For instance the paint that conducts electricity could be missing. Use a Q-tip dipped into alcohol to gently clean any membrane contact that is worn-out or has conductive paint missing.
