Key fob challenge request masking base station
First Claim
1. A system comprising:
- a base station, including a transceiver, an indicator, and a processor, programmed todetect presence of a key fob using one or more inputs from a presence sensor, andresponsive to the key fob being detected, broadcast an interference signal using the transceiver to prevent the key fob from detecting challenge requests and set the indicator to indicate presence of the broadcast of the interference signal.

Abstract
A base station may include a transceiver, an indicator, and a processor programmed to detect presence of a key fob using one or more inputs. When the key fob is detected, the processor may direct the transceiver to broadcast an interference signal using the transceiver to prevent the key fob from detecting and responding to challenge requests and set the indicator to indicate presence of the broadcast. When an access request is received from a modem, using the transceiver the base station may temporarily discontinue broadcast of an interference signal to send a challenge request to the key fob and receive a challenge response, and send a response to the access request including information based on the challenge response.

11. A method comprising:
-
detecting presence of a key fob via a presence sensor; in response to the key fob being detected, broadcasting an interference signal using a transceiver to inhibit the key fob from responding to challenge requests, and displaying an indicator to indicate presence of the broadcast; and responsive to the key fob no longer being detected, discontinuing the broadcast of the interference signal and resetting the indicator to no longer display presence of the broadcast. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system comprising:
-
a transceiver for communication with a key fob; a presence sensor configured to provide a signal indicative of presence of the key fob; a modem; and a processor, in communication with the transceiver and modem, programmed to receive a request to access the key fob from the modem, detect presence of the key fob, using the transceiver, temporarily discontinue broadcast of an interference signal to send a challenge request to the key fob and receive a challenge response, and send a response to the request including information based on the challenge response. - View Dependent Claims (21, 22, 23)
