A vehicle inventory system may include a passive entry system configured to authenticate a key fob and including at least one antenna and a controller operably arranged with the at least one antenna. The controller causes, during a tag challenge period, the at least one antenna to transmit at least one tag challenge. The tag challenge period is initiated based on an end of a key fob challenge period. The controller further receives a tag response to the challenge indicative of a tag in the vicinity of the vehicle.
