I have the same problem that another member had. I have a Steeltek tool chest, I think it came from Costco, (most every thing I have does) that uses a tubular key with the code of 015 stamped into the lock. I locked the box when we moved and can't find the key. I have tried local locksmiths and they can't decode it. Any suggestions, or if someone has a key I can duplicate I would be grateful!!!
