I have a 2004 G35 coupe and the gas door won't open even though all doors are unlocked

SOURCE: I can't open door of gas tank, when all doors

Thanks for choosing FixYa and welcome. Try going through the trunk. There might be a cord or an access port that you may be able to find to get through. It should be on the same side as the gas tank port/gas cap. If your manual gas tank opener is not working, you might be able to get a hold of the cable and pull it. There is a cable that opens it.

SOURCE: power door locks won't lock

the battery in the remote may be flat, if it can replaced replace it & see if that solves the problem,if it can't be replaced you will have to buy a new remote from a Audi dealer......hope this helps......cheers.

SOURCE: can't open hatch and my key won't unlock the doors. how do i open the tank?

Order a new keyfob from the dealer and have them program it to your car.
