Hello,
I am from Germany and drive a '92 190E 2,3.
I've bought on ebay.com the key of a M-Class, because these keys are very rare in Germany and I want to fit in the electronic of my remote control.
How can I open the key? I can open the battery case, but not the other part, where the electronic is in.
Can someone help me?



Hope my english is not too bad.

Regards from Germany,
Phil
