amgjai

i have a 2009 c63 amg and i notice the newer style amg key fobs have the amg affalterbach logo on the back. that made me want to change it to the newer style because my key fob doesnt have the affalterbach logo and the keyfob looks out dated with the circle panic button compare to the new triangle panic button one. i searched on google and found some affalterbach logo cover for the back which is just a one piece replacement. it tells u to take off the spare key and remove the cover, i tried that and couldnt because it seems like the back is a whole piece connected to the key. does that mean i have to get a brand new key inorder to get that amg affalterbach logo or am i just doing it wrong?

thx!
