When replacing the ignition lock with a new key on any vehicle newer, the passlock system needs to be reprogrammed to the new lock cylinder and key. Dealers and certain mechanics have the proper equipment to do so, call around your area. Without these diagnostic tools, there is no other way unless you buy it yourself, but it is hundreds of dollars. Some larger locksmiths who work on autos might be able to help you to avoid a tow.
