I can put up with the common man not understanding how some things work, or in this case, don't work. So I diagnose this 2012 F350 tow-in no crank as a "bad" PATS key. The owner decided to glue a heavy magnet to it presumably to hide it on the vehicle somewhere. It became his driver's only key yesterday.
What pisses me off is the guy has the audacity to challenge my diagnosis. He did pay for two new keys, programmed and gee, what do you know, the truck starts!
