I haven't a clue as to what your device can do, but to activate the lock feature wire "x" needs to be pulled to ground and the unlock feature works by pulling wire "y" to ground; where "x" and "y" are determined by the wiring diagram to be the two wires that accomplish such a feat on the car involved.
