BLEKey is an open-source Bluetooth Low Energy device for interfacing with Wiegand access-control wiring. Installed inline between a badge reader and its controller, it stores recent Wiegand card values and can replay one over the controller-facing Wiegand lines through BLE. It captures the reader's Wiegand output, not the badge's RF/NFC exchange. The upstream repository documents an unversioned Linux GATT example using deprecated gatttool; the command requires an already installed BLEKey and compatible Wiegand wiring. A replayed value does not guarantee that the controller accepts it or unlocks a door. Use only on authorized lab or assessment systems.
