Possible to lock M3 with cellphone in car?

Ah, ok. I thought if you locked the car with the key card the phone inside wouldn’t unlock it, but apparently that isn’t the case.
The car has no way to tell if the BT signal from the phone is inside or outside the car since BT can travel 20-30 feet in some cases.

Normal passive entry/smart key systems can tell if a fob inside or outside since they are pretty short range, easily blocked, and have multiple receivers around the vehicle to tell where the key is.

But they should add that as a safety feature to temporarily disable phone keys until the next unlock if the car was locked with the key card.
