From what I've been able to gather, only a blank brand-new key can be coded to an existing vehicle. Even this requires special tools apart from the common BMW software tools out there (the key is programmed to some code in the car's internal systems). I find it odd that the other keys worked but with limited functionality unless they were also associated with the car originally.
