Smart key is acting odd. When I approach the car it unlocks the doors. But when I push to start the yellow key icon flashes and red car. Whats going on?\
1) maybe the key fob battery is weak 2)maybe there's a fault that prevents the car from "reading" the fob correctly when it's inside. You would need a capable scantool to check the smartkey ecu for codes. (I had problems when my cellphone was in the same pocket as my keys) Posted via the PriusChat mobile app.
