This is the Fob I have.. today the car stopped giving me the Key Logo with the Charge symbol after leaving it plugged in as I drove around yesterday, but the 3 times i went out to the car i had to click to unlock the door with the button.
The wife took the car tonight and it unlocked for her by touch.
What is the point of plugging the Fob in if not to charge it.. (What I was told by the dealer)
