To be honest you may aswell source some known working ones and fit them. I think it's the micro switches inside the mechnisms themselves that wear out.
I had times where i would try to lock/unlock the car from the drivers door and sometimes it would work and sometimes not. Changed the drivers mechanism for known working one and has been fine since.
Just beaware, they are not the easiest things to change as there are screws in places you would think were nothing to do with it, but doable.
