  • Patent number: 8833122
    Abstract: A transport clip for attachment to a key fob is provided. The transport clip includes a neck at least partially surrounding a key blade, which is selectively rotatable between a stowed position in which the key blade is substantially within a fob body and a deployed position in which the key blade extends away from the fob body. The neck prevents rotation of the transport clip relative to the key blade. The transport clip also includes an ear portion that depresses a latch button to an unlocked position, which allows substantially free rotation of the key blade, relative to the fob body, between the deployed position and the stowed position.
