Voiding a standard key code:
If a registered standard key has been lost and you want to disable its use, register a new standard
key or re-register the other standard key. For registration of a standard key, refer to "Standard key
registration:".
Standard key registration erases the stored standard key codes from memory, therefore, the lost
standard key is disabled.
