I had a full failure of the battery after leaving the car for a week without using and a cold snap finishing it off. It turns out to be a cheap battery of which I have now replaced with a Bosch item. Everything is ok apart from now I have no remote locking. The central locking works ok when turning the key in the driverâs door and also, the alarms is armed but when pressing the buttons no locking or unlocking and no remote boot control. Does anyone have any good ideas o experience this before?
