how do you know it "broke?"
i thought mine broke as well but the cable just came out of the cam. if thats the case just put it back. problem solved.
if it actually is broken, buy a new cable and put one end in the cam where the key goes, route the cable through the subframe/rear bodywork to the other cam to open the pass seat.
pretty easy either way, only one costs more
also this is for a first gen, but the process is relatively the same all around.
