These blanks are for newer Bargman locksets, including those we sell. If your Bargman lock was made from 1977 to the present, this may be the blank for you. Please carefully inspect the photograph before ordering. Notice that there is one narrow groove on one side of the key. And on the other side there are two grooves, one narrow and one wide. These blanks can be used to make backup keys on any key cutting machine. Photo shows both sides of blank. Price is for one key blank.
