Missing Keyboard on Lock Screen

I got a system message that the keyboard had crashed. Then my keyboard won't restart. And now that my phone is locked, I can't unlock it to try any of the normal fixes, such has disabling and enabling the keyboard. Yes, I have restarted the phone, that's why it's locked now. I need to save some of the contacts, so a simple factory reset won't work. ADB does seem to be enabled, but I don't know how export the contacts, or install a keyboard. How can I either restore the keyboard, or export the contacts.
