1. An electronic device configured to transmit wireless power to wireless power receiving circuitry in a wireless power receiving device in or near a vehicle that has a vehicle remote keyless system configured to transmit vehicle remote keyless system beacons to a key and to receive wireless key signals from the key, the electronic device comprising:
wireless power transmitting circuitry configured to transmit wireless power signals to the wireless power receiving circuitry to charge a battery in the wireless power receiving device;
peak detector circuitry configured to measure a peak wireless signal magnitude at a beacon frequency associated with the vehicle remote keyless system beacons and a baseline wireless signal magnitude at the beacon frequency associated with the wireless power signals in an absence of communication between the vehicle remote keyless system and the key; and
control circuitry configured to:
detect a condition indicating that transmission of the wireless power signals will create interference with the vehicle remote keyless system beacons transmitted by the vehicle remote keyless system based on the peak and baseline wireless signal magnitudes; and
mitigate the interference in response to detecting the condition.
