Spare parts for Logitech MX Keys keyboards

Not every part of an MX Keys is a key, and most failures do not come from the cap. The X-shaped plastic hinge, which guides the vertical travel, is the part that breaks most often: when the keycap is intact, it can be replaced on its own for €5 (€12 for three, €18 for five). Then come the rubber return pads, the lost Unifying and Logi Bolt USB receivers, batteries that no longer hold a charge and, for heavier failures, the motherboard. Hinges, rubber pads, screws and tools fit the whole MX Keys range whatever the layout; the battery depends on the model (MX Keys or Mini), the motherboard also on the layout and the system (PC or Mac), and each product page states what it fits. There is also the spudger, the flat plastic tool at €1.50 that lets you unclip a key without scratching the chassis or bending the mechanism. Here is the full inventory.
