Generally speaking, you can always change permissions of a file with the command
chmod (eg. sudo chmod 666 /etc/kbd/config).
Permissions of the files are set wisely, so it is a good practice (if you really decide to change the permissions to perform some action) to change the permission later back to original settings.
Before you do any changes, you can see original ownership and permissions information with the command
ls -l.
