So I got a second CA FOB and I am not sure how to get it working. I have read other threads where owners have gotten a new FOB from the dealer and it worked but needed additional coding for CA to work. I got mine from an aftermarket seller (genuine BMW internals with OEM case) and it doesn't do anything. When I put it in the key slot I get the crossed out key icon on the dash display. I tried the sequence from the E39 board (close all doors, turn on ignition, etc) and that didn't do anything. I put the new FOB in the key slot and started it (with my working FOB), let it run for a minute and turned it off, that didn't do anything. I swapped batteries with my working FOB and that didn't change anything either. I contacted the seller and he said our FOBs can only be done at the dealer or by a professional locksmith, I have NCS, tool32, etc, I think I am just missing something and that I can do this myself with the right direction.
