Note: If the Sheet is not currently protected (i.e. IsProtected returns false) the method will not do anything. Also, if the Sheet was not protected with a password (i.e. HasProtectionPassword returns false) the specified password will not be used and the protection will removed as if the Unprotect method had been invoked.
