Abstract:
A method is provided for authenticating a transceiver in a keyless entry system for a vehicle. The method uses a collision avoidance radar system on the vehicle for authenticating a key fob radar transceiver. A lower power radar signal is transmitted from the vehicle. The lower power radar signal is transmitted below an ambient noise level to make the radar signal difficult for an attacker to detect. The key fob transceiver is then authenticated as being a legitimate transceiver for accessing the vehicle using the low power radar signal. A distance bounding scheme may be used to determine if the key fob is within a predetermined distance. Challenge/response communications may be used to authenticate that the key fob is the legitimate key fob.

Claim (Index 19):
The method of  claim 16 , wherein authenticating that the transceiver is a legitimate transceiver for accessing the vehicle further comprises providing the transceiver with a radar transceiver for communicating the challenge response message.
