Key opens door, will not turn in the ignition. Wheel at first was not locked. Later it became locked as I attempted to move it clockwise then back to 'unlock' the ignition cylinder. Later tried my wife's less frequently used key- same thing at first, then it turned. The my older, more worn key, worked as well.

Since then my old worn key works just fine. not at all sure what happened.

I keep bees, often moving hives and related equipment. This kind of vehicle failure could be a major nightmare if I had bees on the back of the truck.
