HAAAAAAAAAALP!!! i disconnected my battery and since the po didnt have a key fob I cant turn it off! i tried the key in the door and unlock it but it doesnt do anything and the alarm keeps on a keeping on...

I found the black box under the dash but unhooking it keeps the truck from starting even though the alarm is off... Can I short some of the wires in the alarm harness to allow my to get to work in the morning?
