What model of RS do you have? Do you have an antenna on your windshield? Is your start button built into the key?

I just installed a 1 way, 200 series starter, and it has a great distance.

I believe that others have upgraded their factory instslled with a better unit. I dont know where the "brains" are from the factory, but adding one after the fact is done behind the glove box, it ties into the TPMS module.
