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: it sells for €3 on its own, against €5 with its keycap. 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. These parts are universal across the range: unlike keys, they depend neither on the keyboard's layout nor on its colour. 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.
