Does the car still turn over ?
If so the immobilisation cut will be to the coil.
Get access to the wiring going in to the alarm control unit & there should be 2 similarly coloured wires in adjacent pins of the plug, possibly green & green/white (depending on the alarm)

simply cut them off where they enter the alarm & join them together !
