Final Update....

we are in the car, the window is in, we have power, the central locking is working, the eka is working, we are mobile!!!!

EKA fix:-
There is a metal rod connector which goes from the bottom of the door latch to the key lock with in the door panel, the rod had come off the key lock. We have secured this and its working now.

Engine disabled:- once in the car, we put the key in the ignition, turned to position 2, connected the battery, close the bonet, tried to start the car, turned off the ignition, press the open button, tried to start the car again and hey presto its working

We have tried to disconnect the rf unit but the car doesn't like it, so it still connected.

Thanks every one on this thread and others for your help
