Hi Ahmad,

Please let me correct it: SAM_LockUnlock is only required if you want to change or update one of the saved credentials. This command start a mutual authentication between the SAM and the host system.

The return value 6985 means the key is already locked/unlocked or a mismatch between unlock key number and version occurs.
