The alarm of my 2004 rx8 will go off anytime I lock it with the switch then try to re-enter after unlocking with the key. (Sometimes if I don’t even try to re-enter)

I have no fob to stop the alarm and I will enter the car turn it in with the key and everything yet the flashers still go (I have the horn relay unplugged so it won’t randomly beep if the alarm goes off while I’m not around it).

I get it to go off eventually but it’s fairly random as to what stops it so it’s a headache. Anyone know what the issue might be? I don’t believe it’s an after market alarm it seems like the relay/box to the alarm is under the hood release pull. (That’s what tiks to the same frequency as the flashers when it’s going off but could just be flasher related). Lemme know what y’all think !
