To proceed a SAM_ChangeKeyEntry you have to execute a AuthenticateHost before with KeyEntry Number and KeyEntry Version who have the right to change.

If you forget who have the right to proceed a ChangeKeyEntry on your KeyEntry. Make a GetKeyEntry and in the result you will have the KeyNoCEK and KeyVCEK.

This library implement the SAM AV1 command if you want to look or to configure your SAM. https://github.com/islog/liblogicalaccess and wiki about SAM: http://liblogicalaccess.islog.com/wiki/doku.php/sam-feature
