If you start by hitting backspace a few times and/or typing random characters and deleting them (to make sure the keyboard's working and sending your inputs where you think) it should obscure the length somewhat.
Hitting Home, End and Ins would "add" another 3 characters yet would not change the password. A full 100+ keyboard needed.
