Its was optional on the 2LT in 2012 when I bought my car, think it was called remote access. Looking on chevys website now it looks like a $300 option 'Keyless Access with push-button start'. However Gm does not include this with the diesel for some reason, I think it should be standard.

I think this should have at least been an option on the Diesel. It has remote start, how far of a jump is it really to go with keyless/pushbutton ignition as well. No option for Manual tranny, so that surely wasn't the hurdle either.
