Huawei keyboard is not working?

My cellphone keyboard just disappeared, now my phone is locked and I have to enter my password, but it's not because the keyboard is gone. Can anyone help me?

Restart your phone

Unfortunately, that is not possible

Why not? You do not have to enter a password to restart

I've restarted it, but the keyboard is still gone

Aso, if you backed up your data you can reset it to vlt factory settings. But you lose all data on the phone, I would take this only as a last resort.
