Z3r0 is right....

Pulling the fuse will disable everything. I think the alarm will still work but no notification at all when arming or disarming. If you like the horn honking, you'll have to go through your owners manual and find the different programs for your car.. You'll have to pull the pgm fuse, turn the key 4 times, turn on the wipers, click your heels together, smack your girlfriend in the a$$, turn the key off, then plug in the fuse for program 1.. you got like 7 more settings to go.. LOL Me, I just unplugged the fuse. Haven't had a problem and I like controling my lights with the switch instead of using the auto lights because they are on a lot due to me having my front windshield tinted, throws the sensor off...
