Open the fob, remove the battery, and carefully clean the gold contact points on the circuit board with a cotton bud dipped in isopropyl alcohol. One must also clean up the black conductive pads on the back of the rubber buttons.
Action 3: Resoldering Micro-Switches
If a switch has actually fallen off, it needs stable hands. The switch should be aligned with the solder pads on the board and thoroughly re-attached utilizing a fine-tip soldering iron. Caution is necessary, as extreme heat can lift the delicate copper traces off the board, ruining the remote permanently.
