Hi all. I need some thoughts and advice on a problem I've got with my 98 Vectra. I can't open or lock the car with the keyfob anymore. I've already changed the battery so that isn't the problem. I've checked whatever wiring I can see that's attached to the control unit and all seems well and the central locking works as it should when I manually lock the doors. There is also no warning lights to say that there's a problem with the alarm/immobiliser. Any thoughts would be great. Thanks Daz
