I almost agree with you, Alvin. But, you assume the hole being referred-to is under the door handle (I also assume that it is somewhere under the door handle, on the step-surface of the running board). We do not know where the hole is in the original poster's truck's running board.
It would be nice to see a photo of the hole that is being referred-to by the original poster.
Otherwise, we are replying-blind.
