Mladen,
I do not believe your card is in life cycle state LOCKED. If so, you cannot select an application, but you have said, that you can. Therefore, it is not LOCKED.
You might get the response because of some other error, for example the key retry counter has expired. Perhaps you have sent INIT_UPDATE and EXT_AUTH with incorrect cryptogram too often, then card internal security mechanisms might apply and disable the use of the key. That is an implementation dependant feature. You must contact the card manufacturer about this implementation specific feature.
For card life cycle setting, use the SET STATUS command as described in the GP card specification.
Regards,
Klaus

Sorry to ask again so quickly, but this is becoming quite an urgent issue
for me. During my search I found nothing on how to determine if a card is
in fact locked. According to the global platform spec, a locked card state
is there to disable "security domain and applications functionality" and
yet I can select an applet and a security domain with no problems, and even
send and receive data from the applet.
But init-update gives me 69 82, followed by 69 85 for EXT-AUTH if I try to
do it anyway.
More importantly, the GP spec doesn't say how to reverse from LOCKED to
SECURED.
Could anyone point me to a resource or give me a hint as to how to resolve
this situation?
Regards,
Mladen
