Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.

Expert:  Chad Farhat replied 9 months ago.

hey how are you

sorry to hear about the problem you having with it
you will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the alarm module in the vehicle.
is it the module, the receiver, hood switch , door switch, wiring etc.. , it could be number of reasons & there is not a fuse or a relay that you can pull out to disconnect it uunfortunately

But for now ,have you tried resetting it this way

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cable don't reach

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You
