Ok make sure you do this before complaining to the shop. Here a few things to note:
With Key #2 you will be recognized as Driver 2, therefore you won't have access to save settings under memo 1, only with the Key #1 can you do that. Also I think with key #2 you can press memo 1 and it won't move, so with key #2 you can't save on memo 1 or use memo 1 and vise versa for Key #1.
Also I've noticed that the memory settings only adjust once I've just got in the car, once I start driving I can move the seat then press the memo button and it won't do a thing.
