I just picked up a 2017 Suburban LT and I got two keys and two remotes with the truck. Both work, but one of the keys is key number 2 (shows up on dash when inserted) and the other key when inserted shows up and number 3. The memory button has 1 and 2, no 3. So is there a way to set preferences for number 3 or to reassign key number 3 to now be key number 1? The selling dealer is 50 miles away so I would prefer not to go back there if possible.

Thank you!
