A mobile communication device, comprising: a processor, a non-transitory memory, a radio transceiver, a display, and an application stored in the non-transitory memory. Upon execution by the processor while the mobile communication device is in a locked state, the application receives a request for a unique two-dimensional barcode comprising mobile communication device information based on an input on the mobile communication device. The application then generates the unique two-dimensional barcode and presents the unique two-dimensional barcode on the display of the mobile communication device. The application further receives a one-time use unlock command via the radio transceiver, wherein the one-time use unlock command has been generated based on the unique two-dimensional barcode and releases the mobile communication device from the locked state.
