2001 Pathfinder with Python Autostarter - keeps cranking and won't start

Hi,

I bought a used 2001 pathfinder with the Python Alarm/Auto starter and no manual, when I click the auto starter the truck keeps cranking but won't start, if I put the key in the ignition(not on) the auto starter works fine.

Does anyone know how to configure the key code to the Alarm? I believe this is the problem.

Thanks in advance Gary
