Many time it is the alarm siren shorting out and drawing down the battery. After it is charged try removing fuse # 9 and see if it holds a charge. Your FOB will nor open the doors until the fuse is put back. If it hods a charge over night, remove the cowl in front of the windshield and unplug the siren. Go to the crossfire forum and type in alarm siren in the search feature for lots of info.
