RE: How do I use the original factory installed security system?
my understanding is that locking either the driver door or the trunk arms the system. Unlocking must then take place from one of those two points to disarm it.
I can't make mine go off when it would do me some good.
I don't know if it works or not, but here's what mine does.
If I arm the system at the drivers door, wait till it activates, and then yank all the door handles, it never goes off. I can pretend to be a thief and it doesn't care.
But then if I forget and use my key to unlock the passenger door first, it goes off when I open a door even though I'm authorized.
When it goes off just go to the driver door, hit lock, then hit unlock and it should go off.
Can anybody tell me if mine is functioning when it should? I don't see the point of an alarm that doesnt go off when a locked door is yanked by the handle.
