You can also use that conventional key to lock valuables inside the glove box and trunk then keep that key when you hand over the electronic ignition key to the valet.
That doesn't exactly answer my question.
Let's say:
1) I drive the car, then park it and pocket my key.
2) My wife drives the car, using her own key.
Now her key will work fine, even though it hasn't been updated with the rolling code laser encrypted key.

wifes key is #2 ( for simplicity reasons for the rest of this post)
You put in key 1, when you start up the car with that key the next code will be saved on that key and in the computer somewhere. You stop car and put 1 in your pocket. You leave with your wife and she say's here honey use my key(2). Well the last time she used it a seperate code(that was to be used on the next startup) was stored on the key and in the car. You put in key 2 and the key sends a signal to the computer with that code, engine starts, and a new code is produced and stored on the key 2, and that same code is also stored in the computer. Same thing with key 1 as well.
I tried to explane it as best I could. there are many on t board that know more about it than me, but thats the general way it works.

The key does not start the engine by just being merely "nearby".
It has to be inserted and communicates via IR.
I think to bypass the security key you have to buy another key to be mounted near the ignition switch in the dash. That way the computer will get the signal from it and start the car. The computer need the signal to start the car, so without a key nearby it will not start. But that makes the car hotwireable as well.
BTW: It hasn't been above 32 degrees here in days.
basically the german car security sys is really complicated and sometimes it's annoying....
