My sister just called me in a panic because her wireless keyboard is only typing numbers and not letters. This is a major issue since she can't log in to her PC, as her password requires letters. She already tried changing the batteries, restarting the computer, and even attempted to use a wired keyboard, but nothing has worked. Does anyone have any advice on how to fix this?

This sounds more like a security key issue rather than a problem with the keyboard itself. If it's a security key problem, there might not be much we can do to troubleshoot the keyboard issue itself.
She could try using the on-screen keyboard for logging in, which would let her enter her password without needing the physical keyboard. After logging in, she can troubleshoot the keyboard issues.
Have you checked if she accidentally enabled Windows Hello, which might have her using a PIN instead of a password? It's worth confirming that she's not entering a PIN when it specifically asks for her password.
It's possible her keyboard could have failed, especially if there's been any spills or damage to the keys. Sometimes certain keys just stop working due to wear and tear.
