My 2001 Isuzu Trooper alarm goes off by itself, I've pulled the horn relay and it still goes off ,any ideas?

check our hood pins and rear door pins.

What is meant by the hood PIN or the rear door PIN?

Thanks

So, whatever happened? Did you try it, did it work?

Everytime I lock my doors, either manually, with the door, or with the remote, 10 minutes my alarm is going off. It's like clockwork. I can't even lock my door now. I wonder if this is the issue.

I'd bet it is. Look for the rubber boot covered switch mounted in the engine compartment (usually near the left fender). It's supposed to contact the underside of the hood when the hood is closed. You can bend the switch mount upwards to make a more positive contact with the hood. Another 'fix' is to just disconnect the alarm horn.
