A patented keyway offers protection against unauthorized key duplication. A manufacturer with a UTILITY patent key system design controls the manufacturing and distribution of the cylinders and key (key blanks). To the customer, this means that keys and key blanks are not readily available in the open market. Only authorized individuals, whose signatures are on file with the factory, can order key blanks, cut keys, and add combinated cylinders for a key system.
Language to use in key system specification:
The manufacturer will provide a highly restricted, utility patented keyway that will be assigned to the end user.
