My wife has switched to first shift and wants a remote start on her 2003 Trailblazer. Any recommendations? I don't know if its possible for them to tie into the factory keyless entry or not. Just tryin to keep things as simple (remote wise) as possible. Thanks

I would call the dealer and ask about a factory remote start. It was 2003 when i left the GM dealership and i remember them being installed on the new cars as an option through the parts dept.

Woodchuck, with your dealership experience, have you heard of anyone retrofitting these into vehicles? Im gonna ask when I make my appointment to get my clunky column replaced

You could try for the factory one like the 07's have or one of the vipers. I like the http://www.bestbuy.com/site/olspage.jsp?skuId=8552318&type=product&id=1188561245745 you make it roll your windows up and down, turn your ac or heat on, up to 6 functions. And it has a 1mile range. I work at best buy so. Im thinkn of getting one myself.
