Abstract
In a vehicle passive entry system, a countermeasure system and method include a remote unit for receiving a passive entry challenge signal, determining if the passive entry challenge signal is valid, and transmitting a vehicle access signal for use in actuating a door look mechanism to permit access to the vehicle if the passive entry challenge signal is determined valid. The remote unit includes an indicator for use in generating an alert if the passive entry challenge signal is determined valid, and a switch for use in manually disabling transmission of the vehicle access signal. The countermeasure system further includes a passive entry control module for mounting in the vehicle, the control module including a transceiver for transmitting the passive entry challenge signal and for receiving the vehicle access signal.
