In the description of the patent it is said that the remote access system in the car and the key exchange information over a wireless communication channel. To ensure satisfactory communication, conditions that pose a risk of interference are identified and appropriate mitigation operations are performed. Specifically, identifying the risk of interference includes detecting radio signals from the vehicle’s remote keyless system, detecting key codes transmitted by the key in response to received signals, monitoring the vehicle’s location, and comparing the measured location data with stored vehicle location information. as well as monitoring whether the electronic device is wirelessly paired with the vehicle. In this case, an inertial measuring unit or other input-output device is used to determine if the electronic device is in motion characteristic of the movement of the vehicle.

Interference mitigation actions are being taken to enable the use of a keyless entry system. These include prompting the user to turn off wireless chargers, adjusting the wireless power transmission system settings, and other actions.
