Tool Box Locks with Keys, 4 Pack Keys Alike 5/8 Inch Lock Cylinder Fit for T-Handle Tool Boxes Lock Cylinder Replacement Truck Toolbox

UPDATE: u/est1985socal was nice enough to find these cam locks on Amazon and decided to give them a try. They fit and work perfectly! Now both boxes open with one key. I ordered the ones without the dust cover as I was able to reuse the ones that came with the boxes.
