Replacement cash register keys can be purchased and received rather quickly. If you can contact the salesman who sold you the register and know that you can achieve your goal through the salesman, that may be the best route. Many business machine supply stores offer cash register replacement keys for many major manufacturer business machines. However, the quickest way to know for sure that you are receiving the correct key could be to contact the cash register's manufacturer directly.
