KBX is the most comprehensive key blank cross-reference, with over 85,000 blanks and more than 4500 photos. Since 1988, we have been adding to this program each year. Old and new blanks can be grouped together with their equivalents. They are separated by length, bow material and other distinctions. The second version of the program includes an additional feature that allows you to add your label to any blank group. It can be used to store hook numbers and any other description that you need for your blanks.
