Well at first I was able to lock and unlock the car until it eventually wouldn't even do that and reported that I should try again later (which I did for a number of days). Strangely it also defaulted to metric rather than imperial measurement without any input from me. I have to admit I was confused by the whole thing but decided that as in the past it would right itself eventually.
I love your suggestion with regard to configuring the bluetooth key but unfortunately I haven't a clue how to do that. Are there instructions somewhere that I can access?
It would certainly be another 'string to the bow'
and thanks for your help.
