i think either you are incorrect about this or if yours works like that it is not a very good alarm????
the switch you are talking about is called a valet switch.. its what you do to put the alarm in the off position so someone can drive your car like going up the ramp on a parking garage and not worrying about the alarm... when you pick your car up you switch it back to regular alarm so it will work correctly.... with your alarm/or the way you saw it works is Like: a low or no battery in the remote is like having no remote, such is the case when a thief is stealing the car, he does not have the remote so he just breaks the window and then reached under the dash and pushes a button and the alarm goes off????? dont think so..
