Take the inner boot skin off. Just one screw then the plastic pops off.
Then you have to get to the three bolts holding the diamond and handle off. They are tricky to get at as the bottom one has a metal skin which prevents easy access IIRC.
Its fairly easy. Once off i dont think you can use the boot button. And theres a big gaping hole on the boot.
The diamond is also plastic welded onto the handle, So you cant take it off and paint it.. Which is what i planned to do.
Best off get a spare, paint it (if thats what you plan to do) then swap the painted over for the normal one.
