The prior owner of my 09 Alpha Off Road had a Code Alarm remote start installed. Have no idea when or by who (in AR where they lived), but it is a single wire trigger that works perfect all the time..... well all the time when I test it since I hardly ever use it. Best thing is it will unlock/lock from about 3 times the distance of the factory fobs. I drive a beater in winter so the Alpha sits on the driveway plugged into a Battery Tender Plus till the roads clear. Got no rust now, I don't plan on screwing that up with road salt.
