Really? If this is the case then I might be interested in a fob --- with my phone, waking the 3 and/or opening the door is not enough, I still have to navigate through the app to "unlock chargeport". Are you saying that the fob does this on walking up to the car or that there's a button combo on the fob to do it, like for the S or X?
I just did a few tests:
Car charging and locked (no key)
- press button on charger and try to pull out charger, it is locked as expected
Car charging and locked (fob in pocket)
- press button on charger and pull out, no issues
Car done charging and locked (no key)
- press button on charger and try to pull out charger, it is locked as expected
Car done charging and locked (fob in pocket)
- press button on charger and pull out, no issues
Car done charging and locked and 'asleep' (fob in pocket)
- in this case I usually need to touch the rear door handle and/or open and close it to wake the car up
- press button on charger and pull out, no issues
