I know that this is an older thread, but just thought I would let you know that the same thing happened to me after I changed my battery. I have a 2015 Ghibli. I did the keyfob operation as well and the radio was unlocked when I started the car. I would love to know why this worked or how it was found, but I am glad it worked! Thanks for the easy fix.This happened when I changed my battery and **** me up no end. Just did the keyfob thing and started engine and it cleared.
