One month ago it was absolutely freezing outside with a windchill of -25. I hopped in my car and while it was slowly cranking it did finally turn over.
As I let her warm up for awhile I noticed the “security” light was solid. I arrived at ny destination, shut the vehicle off and returned to my vehicle 20 minutes later to you guessed it, immediately die and “security” light flashing.

I had it towed to the dealership and they claimed the anti-theft control module needed replaced. I bought the part on RockAuto and they installed it; car ran fine.
Monday morning I hopped in the car (yes, it was cold) and this time it started, but immediately died.

I tried the 3 ten minute reset to no avail.
This morning I purchased PERMANENTLY Disable and Remove GM Security Systems module as I don’t know what else to do.
Why is this happening?
Is there something I can try to at least get the car rolling temporarily?

Thank you all in advance!
