You need to order a new key from a dealer. DO NOT BUY ONE FROM EBAY! The key has a RFID chip that is necessary to get the car to start - just cutting a new blade will not work. The dealer will need your VIN (vehicle identification number) to order the key. If the dealer wants to charge you for programing the key to unlock the doors just politely decline and follow the directions here: https://www.crossfireforum.org/forum...-key-save.html
