I appreciate the tip. Locksmith’s here now. If reprogramming the keys doesn’t work, I’ll look at the BCM and the PATS transceiver next. Thanks!

 

Update - 2 locksmith visits, 1 mechanic, 3 updated ground cables, 1 battery, a few other miscellaneous items, almost 3 weeks, many drinks, and a total of $700+ later, and ……… no change. Superchips computers are still the only ones that can communicate with my PCM. The locksmiths tried 2 with no luck, the mechanic tried 1 with no luck, and the tuner itself will not communicate with the PCM. I guess next up is a new PCM. Also, I now have a Superchips F5 for sale. May or may not be married to my truck. No one knows for sure. 🤷🏻‍♂️
