1. A method for operating a wireless vehicle access key, the method comprising:
- detecting a gesture by the wireless vehicle access key, wherein the wireless vehicle access key is configured to unlock a vehicle and detecting the gesture comprisestransmitting, by a first transmitter of the wireless vehicle access key, a first millimeter wave signal to a location of the gesture, andreceiving a reflected millimeter wave signal by the wireless vehicle access key, wherein the reflected millimeter wave signal comprises a reflection of the first millimeter wave signal reflected from the location of the gesture;
generating a first message in accordance with the detected gesture, wherein the first message comprises radar data based on the received reflected millimeter wave signal; and
wirelessly transmitting the first message from the wireless vehicle access key to the vehicle using a second transmitter different from the first transmitter,wherein the detected gesture is associated with an operation of the vehicle.

14. A method for operating a vehicle, the method comprising:
-
wirelessly receiving, by the vehicle from a wireless vehicle access key, a first message using a first wireless protocol, wherein the first message comprises radar data generated using a millimeter wave radar system of the wireless vehicle access key, wherein the first wireless protocol operates using signals different from radar signals of the millimeter wave radar system of the wireless vehicle access key; processing, by the vehicle, the first message to detect a gesture associated with an operation of the vehicle; and performing, by the vehicle, the operation in accordance with the detected gesture. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A control circuit for a vehicle, the circuit comprising:
-
a wireless receiver configured to receive, from a wireless vehicle access key, a first message using a first wireless protocol, wherein the first message comprises radar data generated using a millimeter wave radar system of the wireless vehicle access key, wherein the first wireless protocol operates using signals different from radar signals of the millimeter wave radar system of the wireless vehicle access key; a processor coupled to the wireless receiver; a non-transitory computer readable medium storing programming for execution by the processor, the programming comprising instructions to; process the first message to detect a gesture associated with an operation of the vehicle; and perform the operation of the vehicle in accordance with the detected gesture. - View Dependent Claims (24, 25)
