I've got a DEI brand remote start. The same company that used to years ago make viper, it may have changed. I love it and would never have a jeep without it. You can add am extended distance antenna to the starter. My jeep starts well well over 200 250 yards away. In open areas and busy city with conflicting signals. It's great to get into a warmed up jeep in the winter! Not only for being comfortable, but the engine is warmed up as well as the trans. I think it'll extend the life of my jeep personally. I haven't cleared frozen windows in years the defrost comes on and i'm always ready to go.
