Hi everyone,
a friend has just gotten themselves on of these cars, and they`ve only been
given a single key for it.  They`ve been told it`s got a "red key
imobiliser", but don`t have a red key, only a dark blue coloured key.  The
car can be opened fine and driven, but they`d like to get at least one spare
key, ideally more than one.  What would be the best and cheapest way of
doing this?

Thanks in advance for your help.
