1. A method comprising:
- detecting, at a first subsystem of a vehicle, a presence of a mobile computing device proximate to the first subsystem;
determining, by the first subsystem of the vehicle, that the mobile computing device has previously established a cryptographic pairing with the first subsystem of the vehicle; and
enabling or disabling, by the first subsystem of the vehicle, a functionality of a second subsystem of the vehicle based on whether a communication functionality of the mobile computing device is enabled or disabled.

Abstract
An event is detected at a first device. Responsive to the detection, at least some functionality of the first device is deactivated. The presence of a second device, cryptographically paired with the first device, is detected by the first device. Responsive to the detection, at least some functionality of the first device is activated or reactivated.

5. A first subsystem for a vehicle, the first subsystem comprising:
-
a processor; and a computer-readable medium coupled to the processor and storing instructions that, when executed by the processor, cause the processor to; detect a presence of a mobile computing device proximate to the first subsystem; determine that the mobile computing device has previously established a cryptographic pairing with the first subsystem of the vehicle; and enable or disable a functionality of a second subsystem of the vehicle based on whether a communication functionality of the mobile computing device is enabled or disabled. - View Dependent Claims (6, 7, 8)

9. A non-transitory computer-readable storage medium having stored therein program instructions that, when executed by a processor in a first subsystem of a vehicle, cause the processor to perform a method comprising:
-
detecting a presence of a mobile computing device proximate to the first subsystem; determining that the mobile computing device has previously established a cryptographic pairing with the first subsystem of the vehicle; and enabling or disabling a functionality of a second subsystem of the vehicle based on whether a communication functionality of the mobile computing device is enabled or disabled. - View Dependent Claims (10, 11, 12)
