Very Strange Problem
 

My mother-in-law has an 05 Ram 1500. Last night she came to visit my wife while I was at work. When she got ready to leave, after placing her key in the ignition, the key would not turn. This morning I tried moving the steering wheel to see if the wheel lock was in a bind. That didn't work and the steering wheel wasn't (isn't) locked. Tried moving the shifter to see if it wasn't completely in park. Shifter will not move. My driveway is on an incline. Any other suggestions on this matter would be greatly appreciated as she is parked in my parking spot!
