1996 Dodge Ram Keys will not turn to start the truck

When trying to start the truck I can turn the key backwards ok, I can turn the key to the off position and take the keys out, I can turn the key 1 position forward but it locks at that position. I can move the gear shifter in the first position but still can not move the key any farther. One more thing is that the steering wheal dose not lock in the off position.
