I got a 02 Grand Prix. Michigan winters suck. Looking at adding a remote start. I see em advertised for $99 installed most cars. I know my car does not have a chip in the key but when I get there the guy starts telling me it's extra because the chip is built into the end of the key etc.... so I'm just trying to figure out if the guy is pulling a fast one on me trying to score some extra easy cash. Just kinda curious.
