It's my first time posting; I have a question about my alarm. The vehicle I have is a 1998 Pajero. I parked for about 4 days now, no driving.. nothing. Suddenly when I use the alarm there's no sound, only if you come close enough you can see the locks open/close and the lights flash. Occassionly the sound of the alarm will chip in but it only chimes 3 beeps and usually that's when something is wrong... Please help me

**It beeps once letting you know it's closed, twice for open**
