Yeah, not achievable without WAMS, there's no option for remote start BCM programming through TIS. It's definitely a proprietary patch done by WAMS.
Easiest is TIS and VXdiag, but yes it could in theory be done by dealer too. But probably for an arm and a leg.

Re: Factory Remote Start
I did make it work also same process as above $40 ACdelco vin license and tool, I actually asked at the dealer I use if I got the WAMS part done would they be able to do it and they had zero clue said anything remote start gets farmed out and told me big $$$, So i bought the stuff myself and worked through it via laptop an frustration.
