1991 Camry Ignition Key or Switch Problem

I just bought a 1991 Camry with 121k miles. The key has a real hard time turning from the lock position to the accessory position. From accessory position back to lock position works. It must be giggled and wiggled until it will eventually turn and start the car.The key is pretty worn and kind of bent from the previuos owner having the same problem.The key looks original. Can a new key be made from that one that will turn the ignition swith, or is it more likely a worn out switch with a worn out key.
