Car Alarms: automate aftermarket alarm, everynight, good luck

Question
This system came installed on my used matrix-It starts up the car everynight at 9:15pm and runs it for 18 mins. This is a pain..how do I stop this from happening?

Answer
Nice. That was un necessary.
You may not like the answer, but it is
an agreement I made with them directly.
Lame as you think it might be,
it keeps me out of court.

But I also guided you to a website where you
could get the assistance you sought without
my breeching the agreement. Sorry if that
did not suit your needs, but I tried not to leave you
hanging.

Being sued is not my idea of fun,
so my response is, please try
to go to the sites I suggested.

Oh well, some folks just have to
vent I guess.

Good luck.
