Slowly working through all the little things on the car. The passenger side central looking doesn't work, doesn't lock or unlock, drivers side is fine but when trying to lock the alarm just keeps beeping. Fed a live to the wire in the solenoid and it seems to move any ideas? Maybe the feed from the car or can I try to wire it into the drivers side wire ?

When operating the lock check to see if there is power to the solenoid. If there is it is likely yo be the unit. If there isn't start by checking the adjustment on the the splenoid linkages and control unit on the drivers side as it is these that all work together to send a signal to the passenger side
