It is a design flaw. When you open one handle there is a bar that engages to open the other latch so you don't have to get up in the truck to open both handles at the same time and the bar is factory bent so it stays out of the way and that is where the flaw is. The bent bar flexes when you try to open it when locked and the only solution I can come up with is to replace the bar with a straight bar and I am not to worried about it being in the way. I will see if I can post pictures of it.
My repair plan failed and I am returning the box and I guess they are complete junk.
