The Owners Manual is a great place to answer your functional questions about the car as well.

Owner's Manual

The rain sensor is activated by turning the sensitivity button at least one notch.

When i set the key memroy, i get in the car, put the ignition to number 2, adjust seat, mirrors and steering wheel. When all done, i put the memory button and store it in 1,2 or 3.

When i then get out of the car and lock then unlock the car, none of the adjustet things should change.

Then i take the girlfriends key, unlock the car, adjust everything as described above, but store it in another number then the first time.

Done like this, the car adjust according to the key which unlock the car.

I hope this made sense, If it doesnt work for you, im afraid i dont know what the issue is..

Good luck.

ok, ignition 2 is when the car is fully on (engine running) correct?

so as i understand:

turn the car on, move my seat, re-program it to a memory position, then turn off, lock the car.
take another key, follow the same settings and set it to memory 2?, turn off the car, lock and it should work?

You dont need to start the car, but shouldnt make any difference, i think.

2 is where it goes after starting the engine, and is right before you start the engine.. If that makes sense.;)

But, yeah, that does it for my car..

DID NOT WORK ..unbelievable!

Worked for me; Perhaps you missed a step in the instructions.
It's easy to make a mistake. Many of us have gone thru this
procedure and it does work.

yeh, thats the most irritating part. i an following it step by step, and different people have assisted me on the forum, but i cannot get individual keys to follow their respective settings! haha..

Perhaps you should consider Post #3
Then follow with the second set of
instructions

post 3 helped me program a key that wasnt even opening/closing doors. which was clutch, but i still cant get the key to be personalized to settings.
