Both keys are the same so unlikely. TBH we're learning every day. Despite owning tens of different vehicles over the years, MGs, Toyotas, Mercs, Humbers, buses, ambulances (yeah really!) this is the most complicated we've ever had. Maybe that's because of the double locking system. Tried to play with the navigation today and failed miserably- although it was a good map of where we were! Ha! I'll have to read up on that too. I'm sure we'll get there gradually- but your initial assistance helped enormously. Thanks again.
