05 altima, remote start, im07 problem

The car starts fine with the key in the ignitionupon RS. So its a bypass issue for sure.  Well i have it exactly the way it reads on the instructions and the programing light just blinks forever when i turn to ignition.  I called Trilogix for help they said to reverse the low can and high can wires that that has been a prob before.  Well that did not work either it just wont take the keys code. Its the only key the customer has black key with nissan logo. I updated the IM07 to version 2.0 also still nothin.  I ordered another thinking hardware failure.  Any ideas

Explain exactly the way you wire it...... so we can see what may have caused the failure.....example..green to red

Junk  bypasses got another in this morn plugged it it works great no wiring changes at all.  Hardware failure  sucks makes yah real wized off when you know everything is wired right.
