Thanks!

Re: How to unlock my card
From the Card Life Cycle State Transitions diagram in GP spec, if your card state is CARD_LOCKED, you can just reverse card state to SECURED. Then everything will be back to normal.

The card won't stop you from getting the private key in any way. It provides you more flexibility but you also have more responsibility.
