Sorry, but you are completely incorrect and do not understand how RF works. Go ahead and enclose the antenna in thick aluminum and let me know how it works ok?
Apple has spent a ton of money designing an enclosure that works as a part of the antenna system. Ever wonder what those lines are for, and why most other phones aren't metal or have "windows"?
If you put BMWs crappy PCB trace key fob antenna inside a 360 degree metal enclosure you are essentially creating a shield. It might still work if you're lucky and only severely reduce the distance it works at.
