As for the RKE, Some dealers will do it .. some wont .. some think of it as cheeting the system, some think of it as a dealer installed option .. like dealer lifted trucks .. it most certainly can be done .. as my deal has done it ... your dealer wanting 450.00 for labour is excessive ... as people get the parts and labour for less. Find a new dealer. A local 5 star dealer wouldnt try it for me .. so i went to another non five star dealer and was told they will try it .. but i eat the cost of parts and labour (parts i bought from them), as i have seen four confirmed successes at this .... i said sure ... they did it .. they were surprised .. they waved the labour as now they have a value added option to offer that they didnt before. I was 1 day away from having an aftermarket viper system added ... and got it done. I love to stay factory as much as possible.
It doesnt take much to add the RKE when doing the remote start .. its just adding GXM to the sales codes + the code for the remote start, if memory serves ... there are a couple threads on here about it.
Good to know that bit about the remote start install .... thanks Ramtech and AI Gator for the added info
I plan on adding this in the fall but would like to do the labour as much as i can myself.
