So this issue has persisted for 6 months, and 5 months ago I got my battery tested,, and it tested good so it's not that. The first thing my car does is blare the alarm, sometimes sometimes key fob won't stop it from going off, sometimes it does. I've checked fuses but not relays. Has anyone had this problem, and what was the fix? I can't keep unplugging the battery everything I stop somewhere
