I just ordered one of those combi-cam locks. Someone told me all the keys for the outside compartments are keyed the same. Figured I might as well leave them unlocked. I am only replacing one of the locks, the one I keep all my tools in. I will also keep my keys in there for the other compartments. No frustration when I need something and don't have my keys handy this way.
I measured the length of the cylinder to figure out which to order. Hopefully that was the right way to do it. We'll see Wednesday when it shows up.
