I have a couple documents that contradict each other.

1. 2009 Buyers Guide
Doesnt show Keyless Go as an option for R/Ts or SEs, only SRT8. Remote Start, however is available on the R/T and SRT8 with the automatic transmission.

2. 2009 Customer Preferred Code Guide
Shows Keyless Go is available on the 27J and 28J R/T Models as part of the AFC: Electronics Convenience Group. It is not available on the 27F and 28F Models.
