Found it - Thanks, what an awesome resource.
And - Found the answer in the tech manual - turns out all 3 buttons are for the Universal Transmitter - each one operates a different frequency transmission for remotely opening garages/gates etc.
So, that explains why nothing happens when I press them - I have not got an electric gate or garage door - and even if I had an electric door on the garage I sure as hell would not be able to fit the car in it!
Taken me four years to find out what they do - how cool is that?
