Remote died and the alarm keeps going off, replaced battery to remote and the alarm is still going off
The remote to lock and unlock my car died. I has my son unlock and open the door from the inside and the alarm went off. I got a new battery and the remote didn't work. The alarm still goes off when I manually open the door.

Try having the key in the 'on' position then disconnect the engine battery for two minutes , reconnect and check system.
