G450h no remote key locking after battery change

[madmuppet]

Hi Guys, After a failed 12v Battery was replaced, the remote keys wont open the car. We have changed the battery in the keys but no luck still, so have managed to only open the drivers door with the mechanical key, but this doesn't open the rest of the doors, also the drivers door master lock switch doesn't function,

Please can some help with where to go next? 

Techstream has come back with the following no communications to some ECU. But I've check some of the fuses - is there a more global fuse for all these systems?

Have you found a solution?

You have to press the green arrow at bottom right to access that computer. You will often have to do this more than once to get communication. Try the drivers door  first. Then entry & start.
