So today I went back out to my car after going grocery shopping and when I hit unlock on the car it unlocked fine. I opened the trunk and the alarm started going off. I hit lock and unlock a couple of times hoping it would turn off, but it didn't. I got into the car and started it and the alarm kept going off. After turning it off and on 2 more times it finally stopped. Anyone else had that happen? Any ideas on how to not have that happen again?
