I have a blank key I purchased on Ebay for my 2005 Crossfire. I purchased this several years ago and now would like to have it cut and programed. I stopped at my local Mercedes dealer thinking that may be the place I needed to go. He advised me that I would have to go to the Chrysler dealer. I then went to the local Chrysler dealers parts department and he advised me that it would have to be sent off to Mercedes.
Couple of questions:
#1 Am I able to get this blank key cut and programed and if so where should I go??

#2 If I'm unable to get this key cut and programed where do I go to get a extra key??

#3 If I'm able to accomplish #1 or #2 above what should I expect to pay??

I live in the Dallas / Fort Worth area.
