Switch that effects my alarm???

There is this switch under the dash of my car on the driver’s side. Today I switched it, and the alarm indicator light stayed red constantly, instead of blinking. I closed the door, but I couldn’t arm the alarm, it just wouldn’t do anything. It started up when I tried, I thought it was a kill switch, but since the car started I don’t know. PLEASE HELP ME!!!

BTW, This is an “Avital Tornado” alarm.

Probably the valet button, turns the alarm on and off.

ok, thanks man!
