Car Key Memory ?

I have electric sports seats, and I've thought that the car key memory means that the seats, radio, etc. will automatically adjust to my saved profile everytime I unlock the vehicle.
Aparently I misunderstood - you must push the memory recall button on the side of the seat before this happens...this kind of defeats the object doesn't it?

Strange thing is that it does recall your settings but only after you've used a different key...

Let me explain: I keep my spare key in a safe place, only to be used in case of an emergency, so we only use the original key.
When my wife drives my car, she moves the seat right forward, and up near the roof. So next time I drive my car, I unlock with the original key and hope the seat goes back to my position, but noooo... I have to do a contortionist act to get in, then push the memory button before the seat starts moving back.

However, if my wife had moved the seat while using the spare key, I could use the original key to unlock and voila - the seat starts moving the minute I unlock the vehicle. Neat trick, just a pity it doesn't work without having to use 2 different keys...

First off, speaking of defeating the purpose - that's what you are doing by sharing the same key. Depending upon when you car was built, and whether or not you've received the lated software update, and whether or not the software update does what it's supposed to do, and whether or not you asked the techs to program the option for you (whew, catching my breath) your keys will recall the seat/memory settings from their last use. This is independent of the memory buttons.

Sounds like you have the systems working the way they should, per your last paragraph. The problem is your weird habit. Look: two people - two keys. Hmmmm, wonder what they might have had in mind there... the EMERGENCY key is the black plastic key. ALSO if you never use the other fob key it will eventually run out of juice and won't work anymore.

I took delivery of my car in late August (built in July) and my car seems to have totally different settings depending on the key used.

I had a problem with one of the keys and when I used the other key, the seats, stereo settings, and even the steering wheel button settings were different for the other key. I haven't had any computer updates done to my car (yet), but it seems that I must have already had the car and key memory set up on my car. Unfortunately, I don't have mp3 or RDS capabilities yet (or DRL settings via iDrive).

So, it appears that with the 2 keys I can have up to 4 different memory seat settings (not that I will need it). When I pressed the seat setting 1 with the 2nd key, it did not have the setting saved from the other key. But when I used the 1st key, the settings were still retained.

I also had to set up the equalizer and other random preferences for the 2nd key.

The reason for this is that the key remebers the last settings used by the car. This means, when you switch your car off - the carkey memory remembers the current radio settings, current seat settings, current mirror settings etc. If your wife uses the same key as you, it takes her settings into memory.

If you two had to use different keys, when you get back into the car (even after she's driven it) it would have the same settings you left. So, the programmable steering wheel buttons would be what you programmed, the seat would be in your position, the climate control will be on the temp you last left it on.

If you are sharing the car, you should use the two keys. That is why they give you two fully functional keys and an emergency key. :-)

Problem solved.

No fortunately I don't have to share my 'baby' with my babe. She only uses it on the odd occasion, like to go to the corner shop, or to move it in or out of the garage, etc. so we only use the one key.

Thanks for clearing that up...

By the way she has a Cooper S, so imagine the acrobatics I have to do to get my 6'6 frame into her car... I've considered going through the sunroof

How does this all work with comfort access? If my wife and I both have FOBs will the settings still be remembered even if we don't put the FOBs in the ignition?

Yes, the CA FOB transmitts its settings via radio

But what if each of them has their respective key in their pocket. How will the car know which radio transmission to use?

I was wondering the same thing.

So the FOB remembers seat, exterior rear view mirrors, heat setting and radio setting.

So it doesn't remember tilt tele. stering wheel and interior rear view mirror.

Is that correct?

Interesting question. Hereís my guess. I know the car can tell if the fob is in the trunk and reopen the trunk if its closed. The car can also tell what door the CA fob is near in order to function. Maybe this ability to locate the fob works inside the car as well. Iím guessing the car can tell what fob is closest to the drivers seat.

Searching this forum I found several threads with information on two fobs in the car at once. The consensus is the fob used to open the driver door takes priority and trades information with the car.

I don't have the electric seats (and hence the memory function), but I was wondering if the car/key memory (or personal profile or whatever it's called) is supposed to remember at least the mirror positions. I tested it out once but when I unlocked the doors the mirrors didn't change position. Do you need electric seats/memory to have this functionality as well??

However, the key does remember all the radio and iDrive settings.
