HP-82104A Card Reader Repair Questions

[AndiGer]

I used some brass "blade" - 0.4mm thick, about 25 mm wide and tossed it inside from the calculator side pressing it upward to try to do no harm to the connectors. With that thickness there is some flexibility of the metal and strong enough to lift the lugs. Maybe a second person holding the reader in place and you try to lift the cover from the rear while push the "blade" inside will be of additional help.
