This morning my remote central locking is not working (battery is only two months old) had to use key to open drivers door. Even pushing the lock unlock button on the door card nothing happens. When i use the remote on the key you can hear the car wanting to do something as there is a click noise, same as when you push the button inside the car. But nothing. Its like its in a deadlock mode. I am out of ideas and soon fuel too as cant open the filler flap. Any help or advise would be great
