I have just become the owner of a 2003 RX 300 the last owner who was my next door neighbour only ever had trouble with a flat battery andcthatvwas because washing and valeting he had all the doors open for quite a while. Now I have touched something or upset something because even after charging up the vehicle quickly looses charge and the key fob wont work the central locking nor work the power door. Sorry for the long tale but can anybody throw a light on the subject
