Mk2 vts alarm

Won't stop going off, I disconnected the ultrasonic sensor wires, nothing changed. I also was unlocked the car and sat in it with the door open and it still went off. Any ideas?

Pull the plug from the siren.

But then the lights will still be flashing. It's a cobra alarm, I'm not sure if the fob battery is the cause of it. Fob has a 3v battery but it is reading 2.68v
