    im not fully understanding what youre asking, but if you unlock the door without the remote, the ignition will not start and your alarm will go off

    well its just a starter kill. If the alarm is armend it will not allow the igniton to send the power to the starter to start the car. So if someone was to break in to your car they would eather have to disarm the alarm or hotwire the car since the ignition is of no use with the starter kill.

    Hope that helps,

    thanks


    this is what the manual say

    Anti-Hijacking: When driving if robbery happend pres key III for 2" to activate the anti-hijaking mode indicated by lights flashing for 10" then siren chirping for 10". Finally the starter kill and alarm will be fully activated to shut off the engine....

    i dont understand that :D

    if i have my car running the ignition kill will not work!
    sorry for my dumb questions

    from what the manual says, holding key three for two seconds will turn the car off, even after it's already been started, which doesn't make much sense - try it, why not...

    It depends on how the relay is wired. They can be normally open or normally closed. Normally open is the better option if security is your only concern, because if the alarm is disabled the ignition wire is apart, and the alarm output is needed to close the path. Normally closed relies on the alarm's output to open the ignition wire but if the alarm is disabled or the trigger wire to the relay is cut, the car will start. Being that most alarms are jammed up under the drivers' side dash, a thief who's willing to spend a minute finding the brain won't be inconvenienced by the normally closed mode. If the relay is normally open, he'll at least have to connect the two sides of the ignition wire, or trigger the relay. So, one more step if he's actually trying to start the car.

    YOu can arm the Hijack function after you are in the car. I close my doors, start the car, arm the Hijack function. In the case of a car jack, once the jacker opens my door and takes me out, the function activates. The car works normal and the jacker can ride off, after a minute the car shuts down.....

    That's pretty cool. So the sensor in the car knows 'where' you are so it knows when you're not in the car? How would this work? Signal being sent out by the remote? Which would run down your batteries? Which would be why you can turn the option off?

    No, wait. If a car-jacker takes off with your car, your key (and thus remote) is still in the car. Scratch my idea.

    Correct, once the door opens, it gets activated. This is an annoyance for sure, if you forget to turn off the hi jack feature. Especially since I had the switch out of the drivers reach, figured that a jacker would be searching under the dash etc. So I had it "hidden" in the car. At first I forgot to disengage it all the time. When I would get out of the car to pump gas etc. Then the car would start chirping, and then the alarm would go off. But now it is just habit to engage, disengage.

    What would really suck is if they crawled through the window....... :eek: then the hi jack feature wouldn't ever be engaged until they opened the door..
