I know to remove a Narco radio (Com 810) there is a hole and you
insert a key... kind of like opening a CD-ROM tray with it powered
off. So, my question is, if I don't have this key, what makes a good
substitute? I tried using a 2" jewelers phillips screwdriver but it
apparently wasn't long enough. Is it just a matter of getting
something longer or is there a special shape to this key?

Isn't it a long-ish 3/16" (forget exactly now which) allen?
