I finally found a locksmith that found a matching blank. The code on the key is not a cut code, it's a blank code. Yet it doesn't show up in any data base. Apparently it's out of China. Regardless, it took him a while to find a matching blank but I now have 4 new keys. The blank he used: ilco GH1

Denver Outfitters wants $40 for a new lockset w/ 2 matching keys, they are of zero help in getting just a blank.
