There are 3 things you can try. Sometimes 1 of the 3 will work.First try to wiggle the sterring wheel back & forth as you try to put the key in. If that doesn't work try wiggling the shifter back & forth while its in park position as you try to put the key in. If that doesn't there is a pin on the tumbler that the dealership is talking about. If you remove the steering column plastic cover thats around the steering column,which isn't that hard. You will be able to see the tumbler. If you look around the tumbler you will see a small round pin. That goes up into the tumbler,try to push it in while you try to put the key in. If none of these things work then most likely the tumbler has an internal problem & will need replaced. I hope 1 of the 3 things I told you about works for you though.
