Beeping in my car

Ok I have a 2003 saturn ion and this morning me and my friend were on our way to school..I started my car and all the sudden I hear this annoying beeping soun coming from under my floorboard..so it wouldnt stop and it only does it when my car is on. So after school I look up under there and I find this device and its flashing red and its wats causing the beeping noise. It was attached to a cord so I pulled it off and it stopped...so then I tried starting my car and it wouldnt start.so I plugged that annoying thing back in. And my car starts. But whats weird is if I start my car first ..and then unplug the unknown device my car still runs...could it possibly be a tracker that my parents put on there or is it part of the car...I need help I cant stand the beeping noise!!!

Thanks a lot

Wow that is wierd. Its not your imboliser is it? Do people really put tracking devises on their kids cars these days? Were did privacy go ??

well I looked at it and it has buttons numbered to '4' so I dunno..and the number '1' is flashing on it

nonono its not

go to a mechanic or look it up

I had to deal with that in my shop
I completely forgot what it exactly iss

but I deff no its not a tracking device
besides how would a tracking device stop your car from turning on and such???

well I dont know anything about tracking devices so I took a wild guess.
ummm thanks. is there an easier way besides going to a mechanic whos going to pull money outta me...like is it something I can buy or fix

I think its something you can do yourself

seriously now I wish I would have paid attention that day so I could help you

all I know is that we were testing circuits and things

maybe you can check your car's manual for information

on the circuitry

AH HA!! ok so I yahoo'd it and it is called a immobilizer!!! and it is beeping because my battery in my car needs to be changed...lol GOD I LOVE THE INTERNET
