Logitech MX Keys repair, fault by fault

Keyspares specialises in Logitech MX Keys repair: since 2024 we have been dismantling second-hand MX Keys keyboards and selling every key individually, hinge included. These MX Keys repair guides gather what we have learned, fault by fault: a broken, fallen-off or stuck key, a spacebar, Enter or Shift key that no longer holds, a battery that won't charge, Bluetooth or Easy-Switch dropping out, a dead backlight, double typing, a keyboard that won't turn on. Each guide starts with the diagnosis, then gives the step-by-step fix and, where one exists, the part to order. They cover the MX Keys, MX Keys S, MX Keys Mini and MX Keys for Mac, plus the Craft, K380, K780, K950 and ERGO K860; two guides also cover the Apple Magic Keyboard and MacBook keyboards.
