BMW e91 Remote control

[barth71]

Hi
I have a car with problem remote control. Car not lock and unlock with remote key . The car had the battery disconnected and then remote pilot stopped working. Engine start ok and no faults in module. In CAS module a both key are Status : key in ignition is remote control. The keys are in position 0 and 1 and everything looks fine. I check fuses and i everything is OK. Central locking working only from interior lock button from dash. In driver door in lock not work. Before changing battery in car everything worked well. Please help how to program this remote pilots ?
thanks for advance
