Welcome and again thank you for your service.
Your fob will not start the car because the lock function will not work. I would urge the dealership to replace or fix the fob and give you an extra one, normally that service costs $119.00 (have them do it free of charge to you and if that does look like it is going well see if your vehicle was sold as GM Certified and have it covered that way).
Oh and I respectfully say this but wouldn't it be nicer if your wife was on the bike.
