Hi, Have a read of UP's post to do the injector seals and he covers the adjustment at the end.

As above for the EKA then check the receiver in the roof lining in front of the rear sunroof is receieving the fob signal. If you do have to replace it it's plug and play. No programming needed.

+1 with Fery. There should be nothing on the plastic halves of the fob -it's all on the ciruit board.
As others have said all you need to do is swop your "old" curcuit board into the new casing.
Sorry I'm too far away to help with Nanocom
