it was killing me too, then, a few days ago, I got it to work. unsure what the difference was, so here's the whole sequence that led to the two honks:
1) unlocked/opened rear hatch
2) closed rear hatch
3) unlocked/opened PASSENGER side door
4) PUT KEY IN IGNITION while SITTING IN PASS SEAT
5) closed PASS door
6) opened/closed DRIVER door
7) began on/off key cycle -> (beepbeep!)
I think the difference was either having a door open when the key went in or that it was noticeably easier to do the key cycle smoothly from the passenger seat. It's easier to push in for the steering lock when going back to "OFF".
Mine's a '99 GT fwiw.
peace,
