i just purchased a 2014 impala limited LTZ { old body
style ) I received a worn out non GM remote with the vehicle that barely works. it has a button for remote start but doesn't seem to work, How to I find out what remote belongs with the vehicle and if it does have remote start? Thanks in advance,

 

contact the dealer parts debt or gm customer assistance; provide the vin

they can look up the vehicle build

 

Thanks for you help
