Hey Paul,I have tried that once the battery is connected open door (alarm starts)start ignition,then I press the button on my dash to stop inside car alarm((movement sensors) it works until I get out and close the door.Also I found the alarm radio code,once I put the code in,it seems to have worked as when the alarm went off I got out shut and locked the drivers door the alarm did not go off...I won't know if that's it fixed now,as it was getting late &dark.try in the morning,see how it is then. I would prefer to disarm alarm,would be easier I think.
