You'd be better off setting
	\def{[\lbrace]
	\def}[\rbrace]
rather than exiting-and-entering math mode as in
	\def{[$\string{$]
	\def}[$\string}$]
Similarly for other def's in your .sty, you should look up the long  
name of the char and use it.

This test works fine for me:

\begin{document}

\catcode`[=\catcode`{
\catcode`]=\catcode`}
\catcode`{=\active
\catcode`}=\active

\def{[\lbrace]
\def}[\rbrace]

\begin[document]

$$ \tt {aba} $$

\end[document]
