    • Slide the mouse's power switch to the OFF position and unplug any cables.

    • Flip the mouse over so the feet are facing up.

    • The unique shape of some mice can prevent them from laying flat. If you need to, lay your mouse on a soft towel to prevent wobble.

  2. How to Open Your Logitech MX Anywhere 3, Soften the mouse feet adhesive: crwdns2935265:02crwdnd2935265:01crwdnd2935265:01crwdne2935265:0
    • If you're planning to reuse your existing mouse feet, the adhesive needs to be thoroughly heated to cleanly remove them.

    • Heat an iOpener and lay it on the mouse feet for about two minutes to soften the adhesive.

    • Alternatively, you can use a hair dryer to soften the mouse feet adhesive.

    • When using a hair dryer, don't heat the feet for more than a couple seconds at a time—anything hotter than just warm to the touch risks melting or warping the plastic case.

    • While you wait for the adhesive to soften, note the following:

    • There are small gaps in the rims surrounding each foot. This is where to insert your tool when peeling up the feet.

    • Push the tip of an opening pick (or spudger) underneath the mouse foot, into the gap in the rim.

    • Go slowly, and make sure the pick slides underneath both the foot and its adhesive pad—these layers separate easily.

    • If you plan on reusing your mouse feet, be careful not to crease them or separate them from their adhesive pads.

    • Slide your pick under the foot and lift to remove it.

    • Repeat the process to remove the three remaining mouse feet. If you're having trouble sliding the tool under a foot, reheat it and try again.

    • To install new mouse feet:

    • Use a pair of tweezers or a spudger to remove any large chunks of leftover adhesive. Thoroughly clean the bottom of the mouse with isopropyl alcohol and a lint-free of microfiber cloth. Allow the surface to dry completely.

    • Peel your new mouse feet off their adhesive liners and press them firmly into place.

    • Gently lift the top shell off the mouse up and flip it over the right edge.

    • Don't try to fully remove the top shell yet—a cable connects it to the lower half.

    • There may be a small piece of adhesive securing the interconnect cable to the board on the top shell, right where the cable goes into its socket.

    • Apply a heated iOpener to the board on the underside of the mouse's top half for two minutes.

    • Gently slide the tip of an opening pick under the cable to separate its adhesive.

My left click started to have double click issue. Do you have any suggestions how to fix it? If I want to replace it, does ifixt have the part? If not, what is the part number? Thanks

Vim - crwdns2934203:0crwdne2934203:0

You could replace the left switch. See step 9 for the part number. You’d need to desolder the switch.
Sometimes it is enough to open the case of the switch and clean or tweak the small metal plate. But this is a very delicate finger exercise.

Tobias Isakeit -

Mine had the left click issue. Opening the switch case and cleaning the contact points resolved it.

Steps 6 and 7 are not necessary to get access to buttons (the most common malfunction). My model had this interconnect cable glued hard to the top half of the device. You can easily remove it without disconnecting the cable, oil the buttons and assemble mouse back

Максим Шилиманов - crwdns2934203:0crwdne2934203:0

My interconnect cable wasn't glued hard, but was attached via adhesive which took careful effort to peel away. I had to remove the screws on the board to get to the lower level to clean up coffee, though fortunately there was very little. However when I went to reassemble, I found a free spring and no clue where it came from. Thankfully, enlarging the third picture in step 5 shows where the spring is under the wheel assembly and I was able to reassemble successfully (also the two screws holding the wheel assembly are slightly longer than all others). I even managed to reinsert and restick the interconnect cable correctly.
