Questions on card status

Hi,I am using GemCombi Xprresso R4 (Java card ,compliant with GP2.1.2 and JC2.2.1)and GemProx-P2 reader.

The card is at the status of INITIALIZED.So I send Initial Update and External Authentication command to the card.The final response is "90 00",which means success.

But after that I send Install for Load command,the response is "69 82",which means "security status not satisfied".

And I tried some other command such as Get status ,which need Authentication executed successfully before,I got the same response "69 82".

So does this mean that my card is LOCKED?Because before the successful authentication I made several fail authentications.And if my card is LOCKED,how can I unlock the card?

If my card is not LOCKED,why both of the commands : Get status and Install for Load return "69 82"?

Thanks!
