2012 e91 with comfort access key sometimes doesn’t unlock or lock so I have to use the key blade. Once inside the car still doesn’t recognize the key until I insert it into the slot. I already replaced the car battery and the key battery because it was doing this. Anyone have any resolutions? Is there a bad sensor somewhere in the car?

Could be a bad sensor or a bad key. If you only have 1 key, it’s rather difficult to know without going on a wild goose chase of problems. The first step would be to scan for a related DTC to see if it’s a due to a stored fault.
