It's nice that this site you mentioned will let you text them your challenge code and they will let you know if they can help you. $20 is steep since we don't know if the donor radio works. It's a good deal of you have a high line radio you know works and paid very little for. Thanks for the refence. Sent from my SM-N975U using Tapatalk
Same here. I am helping a friend move a radio from a donor truck of the same year and shows locked. Calling the service number is disconnected for me too.
