gday,ive been having trouble with the central locking on my '04 wagon,its been taking anywhere from 10 to 30 pushes on the remote button to lock the doors,so thinking it must be dodgy remotes I brought 2 new ones from Nissan at $150 each and another $55 to have them programed to suit the car.seemed ok at first(10 mins) but now its no different to the old remotes,crap,so it obviously isn't the remotes! so does anyone have any other ideas?? any help would be appreciated,thanks.
