I acquired a snap on top box, KRA-59G, through an auction. The box is locked and No key was included. Looking for recommendations, internet search did not help. This lock uses a tubular key. .
Did you try lifting the handle up before pulling the handle toward you? Some Snap on boxes have a little lip that has to be cleared before the lid opens outward so you don't have to lock your box when moving around the shop.. Happened to me. Bought a "locked" Snap on box, got it home and found out it wasn't locked, I just didn't know how the lid worked
