Abstract
A passive start and entry (PASE) system includes a PASE module and a token. The token includes a display. The PASE module generates a low frequency wake-up signal and a high frequency challenge signal for the token in response to a triggering event. The token ignores the wake-up signal if the display is on. The token may turn the display off in response to receiving the low frequency wake-up signal. The token may also turn the display off in response to receiving the high frequency challenge signal.
