Logitech K860 Disassembly
By AlexG • Difficulty: Difficult
Introduction

This disassembly will show you how to get into your Logitech K860.

Step 1
  • Remove all visible screws from the base of the keyboard.
  • Keep all of the screws together. As you remove a screw, note that it matches the other removed screws and keep the same screws together. Oftentimes there are 2 or 3 screws that are different. Keep those separate, document where they go.
  • There will be hidden screws under the plastic feet and underneath the serial number sticker. This is designed as an irreversible tamper protection seal. void your warranty. This screw needs to be removed.
  • As a general warning, this is a difficult item to repair and the likelihood of success is low if you are trying to access the keyboard's membrane. There are fragile plastic supports ahead; you will need to take care.
Step 2
  • After removing the screws from the base, you will be able to remove the wrist pad, which will reveal the other half of the battery compartment with more screws to remove.
  • Anyway, you need to unclip the wrist pad and unscrew some stuff again. Like 4-5 screws here.
Step 3
  • As the frame comes apart be mindful that they are connected via this on/off switch. Carefully wiggle one of the connectors to unplug, and set the base aside.
  • This is where it becomes difficult. Scattered around the metal sheet are dark grey plastic supports that have been melted during assembly.
  • They are essentially hot rivets, and are cheaper than screws. Each one is shaped initially as a cylinder or pillar. During assembly at the factory, after the metal plate is installed, these are all pressed down with heat to mildly melt them, resulting in a slight mushroom head which is visible to you here.
  • To unattach the plate we need to break each one with a sharp knife, by cracking and lifting away some of the flattened, mushroomed 'head'. While this is irreversible, it will not prevent the operation of the keyboard. Later, the screws that have already been removed will now bear the entire load of holding these components together.
Step 4
  • Now you are left with this beautiful view. You can unscrew the ground for the small board and the board itself. You can even unscrew 2 screws on either side of the keyboard.
  • What remains is the key membrane assembly, which is, arguably, designed to be non-replaceable and non-repairable. [Which prompts the reader to ask why does this guide exist at all? -Ed.]
