Agreed. In a faraday, the car shouldn’t sense the fob and act like the second one is there to do it’s job. That, coupled with the fact customer service/techs were perplexed, leads me to believe it was a valid issue. Thanks for sharing @Sam6062. That content is what I’m here forYou fix it by not leaving the FOB in a faraday bag inside the car.
Regardless, The second fob should have worked though so something went wrong.
