Comfort Access Behavior

Has anyone ever left with the key when the car is running? I was driving this weekend in my MB S550 with my wife. She had the key in her purse and left the car to go get a number inside a restuarant. I was to park to car when all of a sudden the info screen in the dash, turned red and informed me that the key was no longer detected! Should have drove it to figure out what would happen. But my first reaction was to simply call my wife to come back. Just curious how BMW handles this situation.

Also since the BMW keys remembers last settings via the key. What happens if both keys with different setting (using comfort access) is brought simulatenously into the car?

If someone with the key walks off, the car will continue to operate. However, once the car is shut off, it cannot be restarted. Or locked for that matter.

Yes, after 20 Sec. it will not restart. It will re-start within that 20 sec. window.

I heard a story about someone in a 7er who was dropped off at the airport in his own car being driven by a friend. He got out at the airport with the key on him. The friend drove off without a key. Hope he didn't stop somewhere on the way home. Owned!

if you and your wife approach the car at the same time and both of you have an individual data set for seats and the like on your keys - the distance between car and keys will be measured.

Within half a meter of approaching the car's door handle, the data set for the seats etc., will be activated. And if theres two of you, it should be that person's data set who is closer to the driver's side door handle or touching it.

I hope this helps.

would be nice if the vehicle allowed you to drive off even if it didn't detect the keyfob (as it does now with comfort access) ....but it would continuosly scan for the keyfob while the vehicle is in motion and if it didn't detect it within a minute or so it would slow down the vehicle and shut it off leaving it stranded on the side of the road...

would've been a great "anti-car jacking" solution for those with comfort access..

only problem is what happens when you have it in your pocket but the battery is weak or dead??

the keyfob in the comfort access option is not rechargeable...

It is.... I remember reading somewhere in the manual that I should drive with the keyfob in the ignition to re-charge it - once every few months...

Thanxs for the info!

Does anyone know about the behavior of the memory settings if two keys are brought in at the same time?
