Zero B

it doesn't turn with the key, but the passenger side door does. So everytime i have to lock my doors, i have to come around from passenger side, only then the driver side door locks. So the driver side door has a problem.Could this be the reason why my keyless doesn't operate either? The honda dealers tride to make the keyless work but it doesn't. Any idea how much it could cost to fix? Everything is factory by the way. Nothing aftermarket.
