Might be cheaper, or easier to just get new locks. If you're looking for more than two keys, check the new lock packages. Seems like I noticed that all the numbers were the same when I bought a package to re lock my set up. I wanted all my boxes keyed alike. It's been awhile, but if you're buying the 3 lock package, you look at the rest of those same ones. I hope that makes sense. Course, if you're looking for a lot of the same key, Sears customer service would be happy to provide all the disinformation, and aggravation you can stand lol! Good luck.
