Flashing security light; immediately dies

First and foremost I would like to thank the administrators of this website for allowing me to join and create threads..
This is greatly appreciated!

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!

did you do the security learn 3 times? or just once? how is the battery? sounds like its on the weak side.

security learn is key to run for 10 minutes off for less then 5 seconds and back to run for 10 minutes tree times. you cant open the doors or mess with the radio or anything, if the battery cant stay alive for 30 minutes key to run, have a charger on it, or jumper cables off a running car to keep your battery up to 12 volts during this.

i like to open the window and work the key from outside, cause who wants to be stuck inside the car for that long, use a timer on your phone. the off then back on, i turn it off for like 2 seconds and back to run.
