She has to have set it up before. There is no way to divine a fingerprint any other way. I guess the only other way would be a faulty fingerprint sensor but that should default to a non-entry.
The fingerprint sensor does not make access control decisions, so the fault would have to be somewhere else (e.g. the software code branch structure that decides what to do with the response from the secure enclave).
