Civic Alarm going off??? Batter died

Hey Guys,.

We have a 2001 Honda Civic.. and the battery died.. Left the stereo on all nite.. And when the batter died the Alarm started going off.. Tried everything.. C ould not get the car to start.. could not do anything..

I ended up cutting the grounding wire at the Alarm siren.. and now i cant get the dam thing to stop.. blinkers are allways going off saying the alarm is going off.. I have sense recharged the battery and been driving it .. but what can i do!! Is there away to reset the alarm?

Thanks Mike!
