I've had my 2010 RS250 since October last year and love today car, but the drivers door never unlocks on keyless entry and hasnt since I've owned it. Passenger door and boot does, just not the drivers door, so if I open the boot or passenger door, the drivers door will open then, or if I press the button on the key fob. When I walk away it all locks up ok too, its just the drivers door not unlocking itself? Does this mean the door sensor drivers side has had it or is it something else?
Could be the lock itself, try swapping the passenger side handle/sensor to the drivers and vice versa and see if the problem moves? Pretty simple to do.
