One of the original remotes for my alarm got stolen and my dealer has
tried, without success, to order a replacement. They claim it's
discontinued and want to give me one with only two buttons, lock and
unlock. My original had two more, open hatch and trigger alarm.
I find it unlikely that it's impossible to find one with four buttons,
after all they were used on quite a few GM vehicles if I'm not mistaken.
They also claim that they can't program the remote, supposedly it's a
different procedure on '97s compared to other years.
Unfortunately it's the only dealer around there and also the one my
insurance company uses so trying another is not an option.
