won't crank over?

dealership thinks it is a security issue

They should know that upfront its their vehicle if its a security guard problem or a fuel/spark issue-

2006 jeep commander won't click or start sometimes...after turning key several times to start, it will start...cluster panel is always well lit. When I turn the the key all the way for a few seconds, I hear what sounds like the starter engaging then it turns over, but sometimes that doesn't happen...I have to wait or keep trying, then it starts

Could be the starter motor, starter relay and ignition switch assuming the battery condition and connections are good.

This guide will help us fix it.
