Alarm Keeps Going Off Help

[jamesey]

i work nights and my new 1996 alhambra is messing with the neighbours sleep , i get home at about 630 am and when i lock the car up with the key within 20 mins the alarm is activated, ive had it plugged into a vw machine and it came up a turn signal low power fault and a immobilizer fault

now when i lock the car or when the alarm is sounding the lights never indicators never flash , should they? where do i start with this one , i do have accsess to a w reg alhambra at the scrap yard for bit so i can replace anybit you think are at fault its just knowing where they are
