Hey everyone!
I am the owner of three machines and I plan to buy and place many more. I like having duplicates of keys for machines in case I ever lose one, and I have been looking into buying a tubular key maker so I can just make them myself. I found the listing on AliExpress (I have bought from this site before and I know what I am getting myself into) and its around $40 before shipping. I am not sure if all vending machines take the same key size, from my research there is 4 different sizes of tubular keys. Does anyone know if there is one standard size or if machine locks come in a variety of sizes. Thank you to all who are taking your time to help!
