I thought 2011 for an XC90 was still just a RFID chip in the key fob and not any form of smart key
@Ghettobird
Have you got vida to plug into the car and see what it says?
Could also be a frayd can bus wire grounding out somewhere
I agree with Deger... should pull the battery and tie the +&- terminals together for an hour and then come back to the car
