Car Alarms: Alarm wont turn off, dash area, oem factory

Question
My sister in law's alrm will not turn off and we have changed the battery in her remote but it will still does not work. She has a prestige ELVATOD APS2K4 ID on the back of her remote. I do not have the owners manuel to see what the programing sequence is to turn it off. She has a 2000 Alero. We also could not get the ignition switch to turn either. I don't know know if this is a related problem. Right now her car is stuck in the parking lot aat work and I need to get it fixed befored it gets towed.  

Answer
Ok, don't panic. Try this.
Look under the dash area, maybe to the left
foot area in the plastic, for a button/switch
that does not look like the OEM factory equipment.

Now put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, press and hold in the button until
the installed LED (the blinking light)
in your dash area comes on solid.

This should be valet. This overides
the starter kill relay in the alarm harness,
and returns the car back to disarmed mode.

The only thing that will work now on your system,
is the keyless entry if installed.

Just Repeat these steps to rearm your system.

That should do it.

Let me know what happens.
