It sounds as though you used to have a key with no “S” and now you have a key with an “S”. That’s why I assume somebody stamped it there to assist them bear in mind what lock it is imagined to open. The “S” doesn’t tell us whether or not it’s a copy or not. Thanks Tom, one other key I have discovered is a digger/excavator key, I simply don’t know for what machine although.
