Default Factory auto start not working

I'm hoping someone else has had this problem.

Whenever I try to use the auto start, my horn will sound off 4 times and then the alarm will engage (weird). trunk and doors are still working. This issue started about 2 weeks ago. No check engine light. I tried unhooking the battery cables for 30 mins with no help. I'm currently using the newest GM key fob (going on 6 months now). I never had this problem occur before. Any help will be appreciated.....

I thinking the vehicle thinks its in "auto theft mode", but i'm not having any other problems that will relate to that. I can post a video to help
