Finally got the vehicle back in for repair, had to break the lock to get the door open,could not get proper access to the door as the rear half of the cab had a built in toolbox, found the loom between the doors all wires broken, replacing loom tomorrow, interesting thing with the replacement lock, turns out that on this double cab front locks are fitted to the rear doors, could not get the supposed proper one to fit.

Thanks to all who replied.
