If you wiggle the key around, or bang on the dash in the area of the ignition cylinder, does any changes occur.

I would make sure the battery connections are clean and tight. Possible that you have some grounding concerns, you may opt to have some diagnostics run on the vehicle to see what communications, or other faults exist.
