1. A method of securely providing a mobile device with a cryptographic key in a vehicle, comprising the steps of:
- generating a cryptographic key pair comprising at least a first cryptographic key for use by an electronic device in the vehicle and a second cryptographic key for use by the mobile device to control one or more vehicle functions via wireless messages sent from the mobile device to the vehicle that are encrypted using the second cryptographic key and authenticated by the vehicle using the first cryptographic key;
creating a label containing a scannable image readable by a mobile device, wherein the scannable image includes the second cryptographic key encoded in the image such that the mobile device can (i) obtain the second cryptographic key from capturing and decoding the scannable image, (ii) store the second cryptographic key, and (iii) encrypt the wireless messages using the stored second cryptographic key; and
providing the label at the vehicle for displaying the scannable image such that it can be scanned in the mobile device at the vehicle by a user of the mobile device.

Abstract
A system and method for securely providing a mobile device with a cryptographic key in a vehicle. The method includes generating a cryptographic key pair that includes a first and second cryptographic keys. One of the keys is used to create a scannable image which is then incorporated into a label that is displayed in the vehicle, either as a physical label mounted in the vehicle or via a display screen within the vehicle. The label containing the scannable image can then be read by a mobile device at the vehicle, thereby providing the one key to the mobile device for use in sending communications to the vehicle.
