Why is my range shorter than advertised?

Our ikey series uses a few different antennas to optimize range and environment can effect range. First make sure all antennas are mounted horizontal, as well as not touching any metal, also inspect for breaks in the wire the jacket. If this is going into a classic vehicle that is made of all metal you may need to try other locations of the antennas to ensure good range. Also make sure the small black antenna that is sticking out of the PKE is hanging loose and free from other wires, this is the receiving antenna. You may notice a slight decrease in range during heavy snow or rain due to the nature of RF.
