I just go the python 871xp installed. For some reason the range on it ***** horribly....No better than my who knows how old avital alarm. Any reasoning for this? Also with the remote start I can even be right next to the truck and try to start it and most of the time the green light flashes and ill get 3 sets of 2 quick beeps from the remote. Then other times (from in my apartment for example) it works fine. Is it something to do with the way im pressing the button? It seems like it wont work, then standing in the same place I can try to press the button in a different pattern and itll work.
