I have a 2010 Lincoln MKX with one button factory remote start. Works really good until it gets cold. Figures. So when I push the button it does everything but start the vehicle. Lights, radio etc all comes on and It gives one beep of the horn. Any idea what the one beep is telling me? I have seen the list as to what 2,3,4,5,6 beeps mean but not one. It has done this twice this winter. Quits working for a while and then starts working. Quits when it gets really cold. Starts great with the keys.
