Does a 2004 Mazda miata key have to be programmed?

A 2004 Mazda Miata typically does not require programming for its key, as it uses a traditional metal key without a transponder. However, if the vehicle has an aftermarket or modified ignition system, or if you're using a replacement key that includes a transponder, programming may be necessary. Always check the owner's manual or consult a Mazda dealership for specific key requirements for your vehicle.
