  • Patent number: 11258480
    Abstract: A key fob including at least one wireless communication circuit, a power supply node coupled to provide power to the at least one wireless communication circuit, a battery node, a battery power circuit, and an inductive power circuit. The battery power circuit provides power when a battery with sufficient charge is provided. The inductive power circuit only provides power when energized with inductive power when the battery is not provided or is not sufficiently charged. The inductive power circuit may include a rectifier circuit and an inductor and may further include regulator circuitry. The inductive power circuit does not perform wireless communications thereby simplifying circuitry and operation of the key fob and a corresponding access system. Since only configured to transfer power, the inductive power circuit may be optimized for power transfer. The access system inductively couples power to the key fob when within a predetermined coupling zone distance.
