Evo-one programs but will not remote start

Question

Programmed fine, updated firmware, still will not even attempt to start. When pressing lock 3x, unit will flash yellow once, on the first lock press. The next 2, it doesn't flash anything. Blue LED doesnt light at all. I have tried everything that I can think of, with no success. Where do I go from here? 2002 GMC Envoy w/factory alarm

Answer 1

Your car is not 3x capable. It doesn't list this feature and even says a separate RF kit is required.
