Help 2010 Genesis Infotainment Screen Won’t Turn Off Key Fob Buttons Don’t Work

[Auttyboo94]

The infotainment screen will not turn off at all. With the doors locked and the whole vehicle turned off. The keyfoh works for proximity start but not any of the buttons work. I just replaced the batteries to see if I could get it to work, but no. The red light does flash on the key fob whenever you push a button but there’s no response from the car. Pushing the button on the door handle does nothing. If the door is open then the lock switch on the inside locks and then unlocks immediately. I’ve tried turning the key 7-10 times. I have to disconnect the battery terminals just to save the battery from the screen being on constantly. I even waited an hour to see if it would turn off and nope. Also when I manually lock the door the cluster says the key isn’t in the vehicle? PLEASE HELP!
I literally just got this car today.
