An apparatus includes a vehicle control system (VCS) coupled to a computer of a vehicle via a CAN bus and configured to present selectively appearance of a presence in the vehicle of a smartkey, e.g., by energizing and de-energizing an actual smartkey of the vehicle. The VCS includes a VCS and a Bluetooth® VCS transceiver. The VCS stores VCS software. The apparatus also includes a smartphone with a Bluetooth® transceiver, and storing an app. The mobile device is paired with the VCS to communicate with the VCS via a Bluetooth® link. The app configures the smartphone to receive menu selections from a user, to generate communications that identify smartkey-enabled features of the VCS that correspond to the selections, and to send to the VCS the communications through the link. The VCS software configures the VCS to receive the communications and cause the vehicle to perform actions corresponding to the communications.
