Abstract: Systems, kits, methods, and software are disclosed for securing access to an electronic device such as a smartphone, tablet, e-reader, portable media player, and the like. The electronic device includes a security application and a network interface. The network interface is configured to be paired with or otherwise communicatively connect to a separate security device. If the application determines that communication is possible or occurring, access to the electronic device may be enabled. If the application determines that communication is not possible, some, all, or substantially all features of the electronic device may be disabled. The disabled device may be re-enabled manually using an override code, or automatically be re-initiating communication with the security device.
