I have seen a lot of problems with the door ajar switches sticking inside the door latches. What you can try doing is spraying a penitrating oil like PB Blaster inside all of the door latches on the sides of the doors and firmly closing all of them. about 10 times. This is the most common problem I see. There is no way to disconnect the alram without disabling the vehicle's starting system. The only other thing you can do is remomve the horn fuse/relay.
