01 Gs Alarm Problems

[Lexnut430]

Hi there, I'm have had a search on the forums before I posted, but that doesn't mean I'm not missing the info.

I was working at the car & removed the door handles.

Then when I was finished I locked the car with the key & I think I pressed a button twice, I really am not sure.

I tried something, opening a door or pushing the door lock rods(door handles are still off) & the alarm went off.

I tried to turn it off with the key, but it wouldn't work.

I opened the windows with the locking rod & put the key in the ignition to start the car, thinking that this would reset the alarm, but no joy.

The only way I could get the alarm to turn off was to disconnect the Battery negative, but every time I reconnect it the alarm goes off.

Does anyone on here know of this happening/how to fix it??

I would really appreciate any help as the car has to be moved soon.

Cheers.
