Hooked up the trailer, loaded the two ATV's and was going to back the truck up closer to the shop to add air to the air shocks. After inserting the key into the ignition, it would not turn. Tried and tried, but it would not turn. Rocked the wheel back and forth, still no turn. Wheel lock was not the problem. Wife checked on the internet and none of the suggestions (not very many) would solve the problem. She finally found a uTube video of a guy that had the same problem with a Jeep. Video said the problem MAY be that the key is not going far enough into the ignition. Dirty ignition? Tried WD40, no help. So, take a soft hammer and tap the key, hopefully farther into the ignition and not break it. He tapped it a couple times and no go. He finally smacked it a good one and IT WORKED! STARTED!
As I've got nothing to lose at this point, I got a soft hammer, hit it a couple times and finally put some force in it and it also worked. Fired right up. Worked like it used to. Was able to start, stop and then remove key and restart it all day without a problem.
Worked all day yesterday and today but ordered a new switch anyway.
Is this a common problem or is my truck just 'lucky'?

I never had that happen with my grandma's 01 Dakota. However her 98 Ram did have that happen. It was a security pin that prevents you from pulling the key out while its running was stuck down. We just sprayed some brake cleaner inside a few times then sprayed some gun oil. After that it never came back.
