If altering the battery does not deal with the problem-- particularly in Megane II and III designs-- the issue normally lies inside the casing. With time, flexing the card in back pockets or dropping it triggers microscopic cracks in the internal circuit board's solder joints, particularly around the battery clips and the radio frequency (RF) transmitter.
