sorry to tell you yes you have to order the key from chrysler/mercedes yes it gets laser cut when my mom first bought her crossfire she lost a key and ran in to the same problem so she had to order directly from chrysler or mercedes i believe that it was $250 or $350 its been 3 years since that happened and took over a week to get the key.

the reason its laser cut is for fur there prevent car thefts from just sticking in a tool to open the door much more difficult for a inset key, but car thefts can program a key by just being close by as you lock your door they pick up that signal code program there fob and then can open your door and if they had time to figure out how to hot wire a car there gone.
