Sorry that people have not responded. Probably because they do not know the answer.
My guess is that there is no radio code. I did not have it in my older 1991 and 1995 Q45's and do not have in my current 2003 M45.
So, if you disconnect the battery, all you should have to redo is re-program the button selectors when done.
I hope i am right! If not, my apologies ahead of time.
