You may have to go through a US Dodge Dealer, rather than just buying on line. The Dealer will want your VIN (Vehicle Identification Number) in order to help you. This is the name of my local Dodge Dealer. I would ask for Service first, and tell them what is wrong with your car and what you need to have done to fix it. Ask for Brian Marshall. He is the Service Manager. Then he can connect you with Parts to get whatever you need ordered. When the parts come in, then Service should be able to pair the key to the WIN. You will have to tell them that you are from Ghana, and will probably have to pay for the parts, labor and shipping first. I have purchased many vehicles from these guys, and they are very good to their customers. Good luck, and please let us know how you make out.
