T2 stock alarm help
 

ok so i pulled my car into the shop for the night, i get out and lock the door with the key but i left my phone in the car, i touched the handle then i noticed the 4way flashers started to go off. now this happend with the key and now if i lock the door from the inside im hearing the little alarm box chirp. i need to kno how to diss arm the stock system? im getting power to the whole car but from the starter to the key.
iv tried to kill the battery power over nite, iv tried to open the car from both doors and the hatch with the key and nothing if turning this off. is there a certain way i need to hold the key? do i need to put the stock ecu in the car for the system to disarm..

it seems that when ever im trying to get the car to a show something stupid like this happens

if its an S4, then you can just unplug the alarm brain box, its either by the ecu or the left front speaker

on the s5, the brain is built into the CPU, so the best you can do is either fix the door switches so it works, or unplug one of em, so it never arms
