It has been a long journey to get to this point. But, I have finally found that my car is not recognizing any of my keys when I try to start it on cold mornings.

Both the red and the green lights on the rear view mirror will flash alternately, the car will crank - but not start. The only code I get it "p1617" It relates to the control module. The module was replaced but the problem resists.

Since, this is happening with all the keys, I am assuming the the problem lies on the recieving end of things.

Can anyone offer some advise?
