Ok, so i have the orginal fab with new battery, 2 aftermarket ones. Issues is strange the fabs will sync but doesn't work from a distance. It does pick up signal when key is in driver door keyhole. The. Forgets .Is this somthing wrong with rcdlr system. I would like to check the fuse but cannot locate. And if i have to change the rcdlr module itself, can i do that myself.
