So I need to replace my key since I lost the panic button part.
the dealership is quoting me $100, but on ebay I found a part thats $26 since the key is already cut.. (sure its a risk)

so my question is the inside part number says 4D0 837 231 P
is that all that I need to worry about? the "P" portion
or does the FCC ID matter as well? MYT8Z083721

I ask cause I found a key for $19 (on ebay as well) that has the P part number but the FCC ID is different.

thanks
