Logitech MX Keys disassembly guide

Difficulty

Moderate

Steps

5

Time Required

2 hours

Introduction

1.Remove the rubber gliders on the backside:

The three gliders on the top are necessary in this step but you will remove the bottom three later anyway so best to do all six at the same time

2.Unscrew the three screws behind the top rubber gliders:

In my case the glue\adhesive covered them

3.Use the ifixit toolkit / picks to open the cover

4.Remove the battery:

Unplug and remove It’s lightly glued on the backside

5.Unscrew the little black screw on the PCB which clamps the antenna cable

6.Unscrew the PCB:

Three kind of big silver head screws

7.Remove the PCB

8.Unplug data cable:

Lift the adhesive tape, then the white part / connector pulls up to release the cable

9.Remove all silver and black screws

10.The backplate cover:

start in the left top and lift / pull very slowly until you completely remove it. It’s pretty robust but the adhesive is very strong so take your time on this step

11.Unscrew all the little black screws and the remove the metal base plate

I have uploaded pictures so please take a look at them if needed

Hope this helps and thanks to all the guys that helped

    • Remove the rubber-feet from the underside

    • The three up top are necessary for this step, but we'll be removing the bottom three later, so best to do them all at the same time

    • Unscrew the three screws behind the top rubber feet

    • Note the leftmost screw is offset to the right, and not in the center

    • In my case the adhesive physically covered the screws - Lightly press with a small Phillips [PH 0] and you'll find them

    • Use a plastic opener to remove the cover

    Bottom three feet are not blocking any screws or clips, they can remain.

    There is a plastic film covering the screw holes, it can be peeled back and replaced.

    • Remove the battery. Note it's lightly glued on the underside.

    • Unscrew two (slightly larger, silver) phillips screws that secure the PCB

    • Unscrew the last small black PCB screw on the top right corner

    • Remove the orange tape securing the serial cable (put it to one side, you'll need to put it back if reassembling)

    • Remove the small jumper with twisted red/black wires coming from it

    • Carefully lift the serial connector (it's hinged) and lift the data cable up and away

    • Remove PCB

    • Unscrew all the black screws along the top (9)

    • You'll have to remove the "head" of the keyboard which is attached with latches that click in. Use a plastic tool to help. It should separate completely from the keyboard.

    Remove 9 black screws in order to remove the circuit/battery housing.

    Remove six silver screws, too.

    • Be careful trying to separate the layers of the keyboard. You may damage the backlight guide.

    The back is glued to the metal baseplate and needs to be removed using a spatula in order to expose the screws.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Do you know how I can turn the keyboard backlight so it stays on, even if if t runs down the battery faster.
I really need that back light. I am willing to risk breaking my keyboard for the reward of having the light. If I am really lucky changing the circuit to add a manual switch for that dang back light :)

I have basic skills and I am still learning...

Thank to all the Content Makers and Fix-It guide makers...!

perhaps I could find the correct voltage for the light and prob with a test light to find the circuit for the back light with out damaging something important, like the old days_?

Hello,

Excellent tutorial!

Could you show me where the 2 red and black wires are connected (data cable I think)?

Mine got cut by accident.

Christophe -

hey, please look at Step 3 and you will see the red and black cables you are looking for

Marts -

remjok -

i don't think you can buy parts from logitech. i would say the best place to try is ebay

Marts -

Thank you, i don't know about Logitech, but nothing - ebay, nothing google search result...
But thank you for this your tutorial.

remjok -

only one key is not working what to do ??

Sangram keshari beja -

What are you using to put back those rubber pads on the bottom? Special Glue?

Boerni -

No, just some double-sided tape is enough for this - The pressure added from the weight of the keyboard will keep it in place, and once it's fully adhered, it won't move because the force is lateral (being recessed) 😁

Mike Page -

Be careful NOT to use Isopropylalcohol in the Transparent/Plastic/Plexiglass thing for the Backlight diffusion plate INSIDE the Keyboard. It will absolutely destroy it.

EDIT: It is I believe PETG and not resistant to IPA.
