Citroen Xsara - Citroen Xsara Coupe Central locking - Peeyabbs

I have just had my wheel bearing replaced and after getting the car back, the central locking stopped working, no connection you would think.

The fob works, if I press the boot button it pops open, if I press the door unlock button the internal light comes on.

If I unlock the drivers door with the key the indicators flash.

But the central locking does not work, and so the boot doesnt lock, not the best policy really.

I have tried resetting the BCI with open bonnnet, side lights etc etc, but no joy, any help is greatly appreciated.
