Why did you change the actuator, passenger side as against the one that gives the open signal, being the drivers side.
The emergency key only release the lock , its got no control over the electrics,.
Would be no good if it did, as if battery was flat, still have no electrics.
Does the internal lock and unlock the doors..
Has the key card been checked to see if its sending a signal out.
Have you a spare key card , does this work, or doing the same, or no spare key card?

 

i had read that it was in the passenger door. -right hand drive!
only the passenger door opened with the key.
no spare key.
it does make a noise somewhere under the centre console when operated and the light in between the dials flashes along with the indicators which makes me think that if it does these things, it must be sending and receiving a signal.
0.05 volt was received on one of the terminals in the drivers door plug connector

 

0.05 volts would not operate a 12v solenoid..
Take/split the multiplug , (It separates) by the drivers door hinge and spray with contact cleaner.
Allow to dry and reconnect.. see if its just a dirty contact
