My wife has been complaining that the lane change function (3 flashes) on the turn signal does not work for her. Yet when I drive it, it works fine. The only difference is she's using the #1 keyless fob and I'm using the #2 fob. Is there any kind of internal programming in these fobs that would effect something like turn signal functionality? Sounds crazy, but there's still a lot I don't know about the electronics of this car!
