99 Intrepid ignition problems

Dansel in distress ! Please help (ANYONE) who may have knowledge of why my ignition switch will not turn. I have tried every thing, it is not due to the steering lock feature. I have had the car for year's and never experienced this. It just will not turn at all. Any advice or suggestion's would be appreciated.

your ignition lock cylinder may need to be lubricated so, I'd suggest spraying white lithium grease on your key and inside of the lock cylinder and see if that helps.
