I recently purchased a used 2014 Volt. It works great except that sometimes the button on the driver door handle won't unlock the doors. When this happens I have to manually unlock the door (this also sets off the car alarm, which is annoying). Once I'm inside and try to start the car I will also get a key fob not detected warning so have to manually start the car. Most of the time, say 9 times out of 10, I am able to use the car door handles to unlock and then start the car as normal.
I don't believe the key fob battery is low because in the times when this happens, when pressing the door handle button to unlock, I hear a slight noise and notice a light come on inside on the dash -- so it appears that the signal is being received but the doors are not unlocking. I am speculating that the 12V battery might be dying. Any assistance is appreciated.
