2000 Impreza Outback alarm

Hey everyone, so I just bought a 2000 Impreza Outback, standard, for only $500! Just needs brakes and two front struts! But I also needed a battery. After replacing the battery, I find my alarm comes on. But not the horn. Just the flashing lights, and you can hear the "click" sound as the lights flash from around the dash. I know there is supposed to be that emergency override button but I couldn't find one. Maybe removed for some reason? I don't know. But I don't have the fob for it. Anyone know how else to turn the alarm off without the fob or emergency override button? Or maybe where the button would be? I searched under the dash on the drivers side all around but couldn't locate it. Exact location perhaps? Might have been something in the way of where exactly it is. Anything could help. Thanks!
