  "textContent": "A Passive Entry Passive Start (PEPS) method is described. The method includes obtaining, via a BLE receiver of a key fob, a first BLE wakeup signal from a vehicle. In response to obtaining the first wakeup signal, the method includes activating a BLE transceiver of the key fob. Upon activation of the BLE transceiver, the method includes activating a UWB transceiver of the key fob via the BLE transceiver. When the UWB transceiver is activated, the method includes receiving a challenge signal from the vehicle via the UWB transceiver. Upon receiving the challenge signal, the method includes transmitting a response to the challenge signal via the UWB transceiver. Based on the response to the challenge signal, the method includes receiving a success signal from the vehicle. Upon receiving the success signal, the method includes deactivating BLE transceiver and the UWB transceiver.",
