2004 Titan Starting issue

I am having this problem more often now and need to know what the underlying issue is. When I go to start my truck all I get is a click.
I start moving the steering wheel back and forth and try again...most of the time just a click. Then I move the column shift up and down
and back into neutral...or park and try again. I go through this procedure for about a minute or two and finally it will catch and start. I have
new battery and everything else is original. Is my ignition tumbler going out? This issue has been going on for about a year now and sometimes
I can go for a week or two and not have any problems at all. Then out of the blue all I get is the click when I turn the ignition to start position.
I had one mechanic tell me it was my starter?...
