In the cool I want category, the Keyport, via NotCot:

“KeyPort - an all in one key fob… just get specialized blanks cut to match your car, house, boat, locker, etc keys and the slot right in. In the press kit it says that it is “created to complement your personal style and organize those jagged objects you can’t live without.” And currently under development are RFID for remote keyless entry, Alarm Remote and Flashlight”

Must. Have.
