Restricted Keys:

A restricted key blank is a keyway and blank for which a manufacturer has set up a restricted level of sales and distribution. Restricted keys are often protected by patent, which prohibits other manufacturers from making unauthorized productions of the key blank. With a restricted security key, further copies can only be duplicated by the locksmith who issued the keys.
‍

Secure records are kept when the restricted key system is set up, as to secure how many number-stamped keys were issued. A signature record form is kept with these records and only these approved signatories can ever request more keys. These days, many restricted keys have special in-laid features, such as magnets, different types of metal or even small computer chips to prevent duplication.
