Actually you just check that negative signal wire for 12 volts or battery voltage when the alarm is on. Grounding that wire will lock or unlock the door.
In attempt to clarify, when the alarm is on check the negative signal wire, you should see battery voltage when it is not grounded. If there is no battery voltage, that is where your issue is. I think for whatever reason there's no power to the door locks when the alarm is on.
