If a custom keyboard is installed and custom firmware is removed from the console, System Settings will be inaccessible and you will not be able to launch the keyboard. This is obviously detrimental to the overall functioning of your 3DS and should be fixed as soon as possible.
There are other ways to reinstall custom firmware on such a console, but they may require additional hardware. This guide aims to reinstall custom firmware without any additional hardware, but if you have the means, ntrboot will probably be less of a pain.
Unbricking a 3DS with a custom keyboard installed
If Internet access isn't currently set up, you can set up an Internet connection from Safe Mode as the keyboard will still work there (hold L+R+↑+A on boot, then follow its prompts).
