It should be a pin that goes through the top of those yellow lift handles to take off that side fender steps and you should make sure you put them back on when you're done taking it off if you have them and if you're gonna take it off then you need to remove pins first by pulling the pens out 1st in order to lift those yellow handles up for the steps to swing down-and-out if you don't put them back on it makes it easy for somebody to come by and just lift it up and take it away and add it to their truck And you might want to consider using padlocks small enough to fit where the pins go through the holes.
