Do we need to occasionally 'charge' the BMW Key Fob ?

[wira]

I thought I read in the manual that for vehicles equipped with Comfort Access, the remote control battery is non-rechargeable.

However yesterday I noticed the comfort access does not work at all ( unable to do keyless unlock and locking ) but pressing the key remote locks/unlocks fine.

After plugging key in ignition for a while, the comfort access works fine again.
Does tis mean we need to charge the key once a while ?

Which series? Batteries on E-series CA fobs are replacable, very easy to remove and replace battery. Not sure about F-series

F series comfort access key fob uses CR2450 cell. It's huge. Cost around $5 per piece. Sony or Maxwell. Can't find Energizer.

Sometimes it's the position of the key fob ......

RBB, what's wrong today? You forgot to show the angle, ambient temperature, etc for CA to work
