Logitech MX Keys: MX KEYS S Battery (is it the same as the MX KEYS model?)

Fri, 14 Nov 2025 08:26:15 -0700

I have a Logi MX Keys S (Model YR0073) keyboard that's having serious battery issues. I'm trying to find a definitive answer as whether the replacement battery part and the process are the same between the original MX Keys and my current model? If anyone has any good info I'd greatly appreciate the help!

Logitech MX Keys: Why did the backlight of my MX Keys stop working?

Mon, 09 Jun 2025 23:07:54 -0700

My Mx Keys has been functioning normally, except for the back light. All of a sudden, the keyboard no longer turns the back lights on.

The only lights being triggered correctly are the ones found on the upper left corner of the caps lock key and the three keys used for switching between devices.

If anyone can advise on what can be possibly done to check the problem with the backlight layer, please do.

Logitech MX Keys: Backlight cycling nonstop why?

Tue, 18 Mar 2025 01:45:50 -0700

My 2nd MX keys keyboard with same issue developed after few months. Backlight cycling on and off regardless of time of the day which drain battery really quick. Looks like common issue, found some videos on YT. Fault lay in proximity sensor that can not be disabled by software or key combination without completely disabling backlight which I want to keep. So far I tried.

latest firmware
blow air to clean dust (sometimes help for little while)
turn off&on power
change to bluetooth connection
change RF receiver

My fix was to disconnect one of the wires inside of keyboard to totally disable proximity sensor.

Logitech do not want to own the issue.

Logitech MX Keys: Unable to change Capitals to small on my MX Keyboard. Caps lock KEY

Fri, 14 Nov 2025 08:32:13 -0700

I have been trying to contact you many times, I have asked machine various times. I purchased my MX Keyboard Direct from you. The “caps lock” key does not illuminate. You may say my Warranty has run out, but it was live when I started to try and contact you, over the last year. Your question pages must be full of my question. But no one ever answered. So with this new page I will try again. “HOW CAN I CHANGE THE caps lock KEY TO ILLUMINATE AND CHANGE FROM CAPITAL TO SMALL PRINTING? Thank you. Brian

Logitech MX Keys: Replacement MX Keys Body Kit

Fri, 24 Jan 2025 08:35:44 -0700

Hi, the top rightmost corner of my Logitech MX Keys broke (see attached). It is the only issue with my otherwise pristine keyboard.

I read that you've just started offering all OEM parts for this product and was hoping to buy a replacement body kit (I believe that's the correct term).

Where on your site might I find this part?

Many thanks, in advance, for your help!

Logitech MX Keys: How does this keyboard detect my hand?

Fri, 14 Nov 2025 08:14:30 -0700

The Logitech MX Keys keyboard has a feature that will light the backlit keys when your hand is in proximity to it.

I can’t see any sensors and wondering if it’s some kind of magnetic field detection?
