I have a 2019 Suburban that I lost my Key fob and key. Had the a key made and setup for my vehicle. It took the User 3 position. I later found the missing key and fob. But I am guessing when they programmed the new key it removed the old one. So now I have a key that is setup for User 2 and works fine all user positions work great. New key for User 3 cannot setup to control memory seats or any other features. Is there a way I can reprogram User 1 key back to work with my vehicle? Or program user 3 to control user positions?
