I think the battery might need replacing in the keyfob but the key would not open the drivers door manually. I eventually managed to persuade the passenger side door to open manually but this then set the alarm off. Got to work (late) and the door did lock maually but still could not unlock it by either pressing the button or trying the key manually in the lock. Will replacing the battery in the keyfob solve this? Was surprised the key would not work manually - is this normal?....................Many thanks in advance..........
