R56 comfort access question

Non Comfort Access vehicles place the key in the slot and the battery charges. No replaceable battery.
Comfort Access vehicles have a watch battery just as onefish2 stated that needs replacement every couple of years. If the key is in the slot, it does not charge the battery at all. You only need to put the key in the slot if the battery in the fob is completely discharged so it can read the key code. Also, some functions like auto up windows are disabled without the key in the slot with the door open. Weird I know.

I have comfort access and the battery comments are correct; the battery is replaceable.
The only time the FOB needs to be in the slot is when it is programmed. You can program auto lock, which doors unlock when the button on the door handle is depressed, number of blinks on the turn signals, etc. Each FOB needs to be programmed and can be programmed for different functions. My FOB is programmed to unlock all doors when the button on the door handle is depressed and on the FOB my wife carries only the driver’s door unlocks.
Auto-up windows work if the key isn’t in the ignition slot.

There is a button on the door handle that has to be pushed - not just touch the door handle. The button is a bit harder to push in than I expected. There is also a 1 or 2 second delay. I find myself using the FOB buttons more than the CA buttons for the main doors. It's great on the clubman rear door. The CA is built into the door latch so you don't have to push a button on that.

When the engine is off and the FOB is not in the slot, the windows and sunroof do not operate at all IF a door is open.
With engine on and a door is open then the windows will operate but auto up will be disabled. Auto down will still work.
When engine off and a door is open, and FOB is in the slot, then the windows operate same as with engine running.

Another reason to put the FOB in the slot once in a while is to transfer service information to the memory in the FOB.

I’m in the service business and I’m in\out of my car a number of times a day. I leave the FOB in my pocket and I rarely use it. I love the comfort access.
