So I've been dealing with this SEE DEALER NOW, SERVICE REQUIRED message for awhile now on my overhead display. It's annoying! I've attempted to reset it twice out of about 30 attempts with the brake/gas pedal method. I bought a used RACEME tuner yesterday off marketplace to find out from RACEME that they can't reset it to my VIN. For the hell of it today I plugged it in and it shows one code, P0513. I managed to use the tuner to clear the P0513, invalid shim key, and the message on the overhead display is gone. Just might be something for everyone else to check out. BTW, as far as I know my key is original but I bought the truck used so who knows.
