I live in a condo that has an access control using an HID Prox Pass II. It activates the gate when the pass is within 24 inches of the reader. It works fine on all model cars and under all conditions. However, it does not function with my model S and after several replacement cards, I determined that the car damages the card and they can no longer be used at all. The system involves 125KH. My theory is that the car emits some sort of electric field upon approach that effects and damages the pass card. The technician at HID and Tesla never heard of the problem but both said it is a possibility. Any thoughts/suggestions?
