never looked at the tx electrics(which im presuming you have?)
but i would presume that the 2 systems are separate(central locking and motion lock)
i have lots of knowledge of the metro electrics,and there central locking and motion locks are separate.
from what i can tell from the wiring diagram of the tx's there is a motion actuator so it looks to me like the motion actuator and locking solenoid are separate there.but not 100% sure as i've never had to take it apart.
nothing to worry about as long as your motion locks are working
