    both key fobs are acting the same way.
    the car wont turn on unless the key fob is in the dash. the rear hatch wont open unless the unlock button it is pushed twice then the rear hatch can be opened.
    i did some searching and its looking like the 12 v battery could be causing this. its an 3 year old optima. is their a way to get the car to tell me its voltage?
    also we had about a 7-8 mpg drop on the last tank of gas.
    car has 122k on it. its an 2007.
    thanks for any help.

    Multimeters are inexpensive and nice to have for all kinds of things......including checking batteries.

    Just from what you described, it sounds to me like the batteries have died in BOTH of the key FOBs.

    agree on the weak 12 volt.
