Hey everyone. Does anyone know what it means when the red light is blinking on the Key Fob? The indicator light is constantly flashing on my original 06 tC key. I just replaced the battery and it started blinking and now the car is acting very weird. Specifically, it is not registering the key to be programmed with the car. The car keeps auto locking over and over and over eventually I had to take the battery out of the key fob.
