The key doesn't actually save anything, the car does all the 'saving' for up to 4 keys max and it recalls them depending which key is being used.

When you unlock the car it moves the seat and mirrors back to wherever YOU LEFT IT when you last locked the car with that key thats it, regardless of whether you left them in a position that happened to be M1 or M2 or neither of those, it doesn't matter as it just puts it back to wherever it was when your key last locked the car.

Also, depending on which key is used the car remember all the audio, aircon, idrive etc settings for that key so your prefered radio station comes on and the temperature is set for that key etc etc. Same with the seat manual memories, it also remembers the manually saved M1 and M2 memories associated with that key.

All current settings are associated with a key when the key is used to LOCK the car, and recalled when it used to OPEN the car.

There must be a list of what functions are stored key specific, but there are a lot for sure.
