The value of a patented key system lies in its ability to control key duplication. This control extends to the ordering process. One way to control and manage the ordering process for your key system components is through a Letter of Authorization. Authorized signers are established with the manufacturer, and only those individuals whose names are on file will be allowed to order product and materials for your system. Check with the manufacturer on what checks and balances they have in place to ensure that only authorized individuals can order restricted key system materials for your system. Language to use in key system specification:The manufacturer will implement a Letter of Authorization policy that only allows an authorized individual(s) the authority to order custom coined cut keys or key blanks (send sample letter of authorization).
