Abstract
A keyboard of an information handling system includes keyboard (RF) transmitter/receiver that provides range information for a mobile device paired to the keyboard RF transmitter/receiver. A keyboard controller is coupled to the keyboard RF transmitter/receiver and is responsive to the range information indicating the mobile device is out of range to disable key input data of the keyboard. After the key input data is disabled, the keyboard controller enables the key input data responsive to the range information indicating the mobile device has come back into range. The keyboard RF transmitter/receiver communicates with a host RF transmitter/receiver over a first RF channel and communicates with the mobile device over a second RF channel. The keyboard controller enables the key input data responsive to a successful override of the keyboard input data being disabled. The override is a predetermined key sequence and/or a valid finger print.
