Abstract: Methods and apparatus are disclosed for authentication of mobile devices for vehicle communication. An example mobile device for vehicle communication authentication a communication module to receive a signal from a vehicle, memory including an application for accessing digital keys, and key accessor. The example key accessor is to activate, in response to determining the application is inactive, the application utilizing the signal. The example key accessor also is to access a key via the application and send, via the communication module, the key to the vehicle.

Abstract: Method and apparatus are disclosed for priming vehicle access based on wireless key velocity. An example vehicle includes a communication module to receive a signal from a wireless key of a user that includes velocity data of the wireless key and determine a distance to the wireless key. The example vehicle also includes a vehicle primer to determine an arrival time of the user based on the velocity data and the distance and prime the vehicle for access before the arrival time.
