I can't use my smart card any more. When using it to unlock my PC, I get "smart card is blocked", and in other scenarios I am told my PIN has been guessed incorrectly too many times.

I don't recall guessing incorrectly, but anyway I need to unblock my smart card. How can I do this?

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

Without knowing what kind of card you're using: often resetting is not possible. Once blocked, all access to the smart card is blocked, including any access that might be used to change the PIN.

So I guess you need to find a way to register/associate another card with the same computer.

(Providing more details on your system may help though.)

Thanks. +1 since I didn't even know that the type of card mattered. – Andrew Arnott Sep 12 '09 at 23:54
I've added to the Q title the type of card. – Andrew Arnott Sep 12 '09 at 23:56

It turns out that Microsoft employee smart cards can be unblocked even off the corporate network. Employees should contact MSIT for help.
