Remove the battery from the remote's battery compartment. Remove the screws from the back panel of the remote with the Phillips jeweler's screwdriver. Pull the back panel off. Remove the screws surrounding the circuit board in the front panel with the Phillips jeweler's screwdriver. Pull the circuit board out of the front panel, turn it over and place it on a table. Locate the contact plate that the remote's front button presses -- the contact plate will be a metal tab raised above the surface of the circuit board. Moisten a cotton swab in distilled alcohol. Rub the swab against the sides and beneath the metal tab. Blow the sides of the metal tab with a burst of compressed air. Rub a dry swab against the sides and beneath the metal tab. Reinsert the circuit board in the front panel of the remote. Reattach the screws. Place the back panel back on the front panel and reattach the screws. Place the battery back in the battery compartment and close the lid.
