Abstract
A primary portable device can access a vehicle by transmitting an activation message including a vehicle access credential to the vehicle. The primary portable device can additionally enable a secondary portable device to access the vehicle by transmitting the vehicle access credential to the secondary portable device. The connections between the primary portable device, secondary portable device, and vehicle can be based on a short-range wireless protocol, such as Bluetooth or Bluetooth LE.
