TPMs prevent guessing the owner password. Using the incorrect owner password once might cause the TPM to respond as though the correct owner password is incorrect or cause the TPM to be unresponsive for a period of time or until the computer is turned off.

The TPM state must be on and owned to perform the TPM reset lockout action.

After the TPM reset lockout action was started, the TPM state may have changed or the TPM may have stopped responding to prevent guessing the owner password. If a second attempt to reset the TPM lockout was not successful, wait awhile and turn off the computer before you try again.
