Sucks to have a broken key. It may be best (if your not sure you can do the replacement) to send the key to one of the shops members recommend here in the forum, that replace the entire keys, that'll make a new key to install into the FOB. You might have to send the second key with it (if only one, do what Zip439 said about going to Chrysler for the key code). Under NO CASE, do you let Chrysler either fix the key or service the car!!! Good luck!
