Hi I have a 2014 Lexus is 250 F sport. I changed my car battery and after, my Fob key stopped working to open and close doors. The car starts just fine also when i put my hand on the door handle it opens auto. So the only thing is the Fob key, not sure if theres some restart or something to it, I have changed the battery on the Fob key as well. Maybe some Fuse went bad? Any help would be appreciated i tried searching all over couldn't find any help.
