Hello and thanks for allowing me to join. My '00 GMC's alarm started going off by itself. Anyone else had this problem? I would like to disable it if possible. Thanks.. Will

Welcome to gm-trucks Will. While I've never had this issue w/ my 02 after looking at the service manual I don't think you're going to be able to disable the system. You can however keep it from arming by locking your doors manually.
