2003 monte carlo 3.4 sunroof auto.How can I tell if I have a remie starter with just a key

 

I don't know the answer to your question and I have looked online to see if I could find something but came up with nothing.
You could try calling GM or going to a dealer with your VIN number and they could tell you if it was an installed option when your car left the factory. Not sure how you tell if an aftermarket remote start was installed.
I am sure someone will have an answer to this!!
