This solution more than likely will require internal steering column inspection.First make sure the entire steering column is not loose.If you can move the steering wheel w/column from side to side or up and down more than 1/2 inch it's loose.Sometimes the key will engage while wiggling the steering column.There are 3 torx bolts deep inside the column that need tightening.Second,the Ignition key cylinder may be bad and need replacing
