I don't know why you want a key blank, unless it is to cut a new key. I would say if you want copies of the keys you have probably not, unless you have the key code. Take your key to True Value or some other hardware store and try to get a copy made. If it works great! Otherwise you will need a locksmith. They can "read" the keyway, and punch a new working key. If you are really pressed for cash you can do as my dad did. He would take a nail, pound it flat, and with a triangular file make a key. It is possible you, just need HUGE amounts of time.
