The ignition cylinder is removable. Take it out, clean it with some throttle body cleaner and then lubricate it with some gun oil. See if that solves your problem. Don't try to clean and lubricate the cylinder while it is still installed, you will just make a huge mess.
Directly under the ignition key cylinder is a hole is the plastic trim, turn the key to the ACC position or the Run position. Insert a small Phillips screw driver or a punch and press upward gently. There is a small button you are trying to push and when the key is in the right spot and the button is pushed, the lock cylinder and the key will pull out of the steering column. (If you have trouble, you can remove some screws and the bottom plastic trim can be removed. The button will be easier to see and activate). Remove the key and clean/lube the cylinder. Put the key back in and slide the cylinder back in place.
