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.

A system and method for a door system is disclosed. The system produces an inductive power transfer signal and modulates the inductive power transfer signal. The system also encodes data within the modulated inductive power transfer signal and transmits the signal at a door frame of a door. At the door, the system receives the modulated inductive power transfer signal and extracts data from the received signal, and transduces the received signal into a door power signal. The system also supports secure data transfer by encrypting the encoded data at the door frame and decrypting the extracted data at the door. As a result, the modulated inductive power transfer signal between the door frame and the door provides a secure wireless data transfer channel for configuring components at the door and/or displaying data at the door, while also providing power to components at the door.
