2006 CHRYSLER SEBRING SEDAN key shell is meant for customers who have a working remote head key that is cracked or broken. You do not need to purchase the complete key if your remote functions are working normally. The blade is molded into the plastic head on remote head keys, so it must be cut to match your original at an automotive locksmith or dealership. Once the new shell is cut, you can remove the remote part from your original 2006 CHRYSLER SEBRING SEDAN key, place it into the new cut shell, and it will work just as normal. The new shell will NOT start the vehicle without the original remote part inside of it.
