I never made a key myself but I have seen people and minute key kiosk at Walmart making a key. It is different from what we have here Elmcreek. The machine at Walmart and the kiosk are different because those ones you just insert the key and hit start the machine will cut by them-self. As the one at Elmcreek I have to push the cut through the saw manually. First try I messed up, but afterward, everyone came out perfect.
