My advice is to use rev 1 or rev 3 !!!.
there are several replications of the key-fob that are NOT made by me and i have no afiliation with BMW what-so-ever , other than that i own a Mini JCW.
This is revision 02 of the Mini Car Key Fob, as replacement for the original Mini-made large ring-shaped Fob.
Fitting is perfect , but the backplate
of the key containing the text "Mini" is hard to remove
after its closed.Flexibel plastic is ok because its removeable without removing the backplate.
Look at what to do before attaching it to the key.http://www.northamericanmotoring.com/forums/f56-hatch-talk-2014/264983-the-new-key-fob-for-the-f56-15.html#post4197128
Mounting especially in metal:first - remove the back of the key containing the "MINI" textsecond - slide out the original ring-shaped keythird - edit the key like metioned in the link
and slide in the new Shapeway’s printed one.and finally - close the back of the key.
