Why would my alarm go off for NO reason what so ever? 4x in last 2 days. on 2009 Hyundai Elantra

also noticed when I activate the LOCK on my fob the lights don't blink on my car. ONLY when I UNLOCK it blinks. Does that have anything to do with my alarm going off? I hate to leave it unlocked. It goes off in the middle of the night/wee hrs off the morning, anytime it wants. HELP!!!!
