Slightly lift the AirPort/Bluetooth card and pull it straight out its socket.

Do not use excessive force to pull the end of the AirPort/Bluetooth card away from its socket on the logic board. Doing so may damage the socket.

When reinstalling the card, be sure it is properly seated before reinstalling the retaining screws.

If the AirPort/Bluetooth card is properly seated, its screw holes should align with those on the logic board.
