Hello, my mom just bought a 2003 MDX and last night she left her dome lights on and killed the battery. I came over this morning to jump her car and as soon as it started up the factory alarm started going off for about 3 minutes then stopped, now every time you open the door or start the car the alarm goes off for a few minutes and then stops. Was hoping someone had some info on here, thanks in advance!
