hi chaps, brilliant advice, I have just opened the key - no chip, so I went outside and looked in the dark with my big 'man torch' and hey presto, there it was, sitting on the drive from a month ago, dropped it in, and the key fob now works. Drop of super glue to keep it in place for when the missus busts it again! thank you. Im doubly pleased because the car also has a knocking from the front suspension and reading other posts it seems very likely to be the drop links - well pleased - excellent forum, thanks all Stew
