Unblock User PIN

When the User PIN is blocked, it can be unblocked using the Card Admin Key.

The PIN Unblock command uses the standard Microsoft Windows Smart Card mini driver unblock command which is supported by any compatible card management system or utility, including the Versatile Security VSEC/CMS series.  The system on which the unblock is done MUST have the PIVKey Minidriver installed.

You can also use the PIVKey Tool using the following command - where the admin key needs to be changed to the actual admin key for the card.

pivkeytool.exe --unblockpin "000000" --adminkey "000000000000000000000000000000000000000000000000"

Warning

If you enter the wrong Admin Key more than 5 times in a row, the Admin Key will be permanently blocked, and cannot be used for unblocking or other purposes. If you see the following error stop, and verify you are using the right Admin Key.
