I have a 2013 Nissan Murano with the evo-all acting as a standalone remote starter. When attempting to remote start, sometimes it works, and sometimes it does not. The times it does not, on the vehicles display it comes up as "no key" and then switches to an image of no key in the transponder port. Does this have anything to do with installing a diode? I see on the PDF install guide under parts listed is one diode, but it is not shown anywhere in the schematic on where to install said diode.
