What would happen if I unplug the tow module ? Also I took out the batteries in one of my fobs forth entire night to see if it would loose its sync and react differently then the other one. But when I put the batteries back the next day it still flashed the car lights and looked like it didn't affect the sync.. Is this possible? If the fob would loose its sync would it not have any affect on the car.. No flashing lights and nothing.

Oh and I changed the alarm module as the internal battery wasn't any good any more
