Mercedes Smart Key Shell
 

I have a Mercedes Benz Smart Key working properly but the shell is very worn.
My key is the one with chrome on the sides and it has three buttons and one "round" panic button.
I bought on E-Bay to, if possible, use the shell only to install my original key on it.
The one from E-Bay also have three buttons and one "triangle" panic button.
My key is for a 2009 Mercedes Benz E-320.
Please let me know if it is possible and how to do it. I am very skilled DIY
Thanks.

i think the answer is going to be no. the triangle key is the v2.0 of the chrome
Smartkeys and those buggers are plastic fused together. I'm sure that a very
creative person could cut it open, since anything is possible. but in its current
state, it is much more difficult to open up v2.0 key (chrome key, triangle panic,
and segmented buttons, versus the v1.0 (with round panic emblem and unipanel design).
