I haven't installed alarms and stereo equipment in many years, but Blue is a common wire to run when you need extra length. It sounds like there is a signal that is not allowing the RS to take over. First thing I would look at would be hood pin switch. Follow the wiring where you found your hidden key (can't believe in this day and age people still use this). it will lead you to the module. Do you use your factory Key FOB or is it aftermarket?
