1 – Mac layout
2 – Easy-Switch keys
3 – ON/OFF switch
4 – Battery status LED and ambient light sensor

Battery Status Notification

Your keyboard will let you know when it is running low. From 100% to 11% your LED will be green. From 10% and below, the LED will be red. You can continue typing for more than  500 hours  without backlighting when the battery is low.

Plug the USB-C cable at the top right corner of your keyboard. You can continue typing while it is charging.

Smart backlighting

Your keyboard has an embedded ambient light sensor that reads and adapts the level of backlighting accordingly.

Backlight is turned OFF.

There are eight backlight levels.

You can change the backlight levels at any time, with two exceptions: the backlight cannot be turned ON when:

• The room brightness is high (above 200 lux)
• The keyboard battery is low (below 10%)

Software notifications

Install Logitech Options+ software to get the most out of your keyboard. Click logitech.com/optionsplus for more information.

1. Backlight level notifications
   Change the backlight level and to know in real-time what level you have.

2. Backlighting disabled
   There are two factors that will disable backlighting:

When your keyboard has only 10% of battery left when you try to enable backlighting, this message will appear. If you want backlight back, plug your keyboard to charge.

When the environment around you is too bright, your keyboard will automatically disable backlighting to avoid using it when not needed. This will also allow you to use it longer with backlight in low light conditions. You will see this notification when you try to turn backlighting ON.

3. Low battery
   When your keyboard reaches 10% of battery left, backlighting turns OFF and you get a battery notification on the screen.

4. F-Keys switch
   Press  Fn  +  Esc  to swap between Media keys and F-Keys. We’ve added a notification to let you know you’ve swapped.

NOTE: By default, the keyboard has direct access to Media Keys.

Logitech Flow

You can work on multiple computers with your MX Keys keyboard. With a Flow- enabled Logitech mouse, such as MX Master 3, you can work and type on multiple computers with the same mouse and keyboard using Logitech Flow technology.

You can use the mouse cursor to move from one computer to the next. The MX Keys keyboard will follow the mouse and switch computers at the same time. You can even copy and paste between computers. You will need to install Logi Options+ software on both computers and follow these instructions.

You can check which other mice are Flow enabled here.

FAQ

Frequently Asked Questions

Can I use MX Keys for Mac on Windows?****

• Your MX Keys for Mac can be used on Windows 8, 10, or later. Note that only basic features of your keyboard will be functional.

• • Bluetooth mouse or keyboard not recognized after reboot on macOS (Intel-based Mac) – FileVault****

• If your Bluetooth mouse or keyboard does not reconnect after a reboot at the login screen and only reconnects after the login, this might be related to FileVault encryption.Potential solutions:

  • If your Logitech device came with a USB receiver, using it will solve the issue.
  • Use your MacBook keyboard and trackpad to login.
  • Use a USB keyboard or mouse to login.

Note: This issue is fixed from macOS 12.3 or later on M1. Users with an older version might still experience it.

• When FileVault is enabled, Bluetooth mice and keyboards will only re-connect after login.

Pair to a second computer with Easy-Switch****

• 1. Select the channel you want and press and hold the Easy-Switch button for three seconds. This will put the keyboard in discoverable mode so that it can be seen by your computer. The LED will start blinking quickly.

  2. Choose between two ways to connect your keyboard to your computer:
  • Bluetooth:****  Open the Bluetooth settings on your computer to complete the pairing. More details here.
  • USB receiver:**  Plug the receiver to a USB port, open Logitech Options, and select:  Add devices**  >  Setup Unifying device**** , and follow the instructions.
  3. Once paired, a short press on the Easy-Switch button will allow you to switch channels.Your mouse can be paired with up to three different computers using the Easy-Switch button to change the channel.

How to enable direct access to F-keys****

• Your keyboard has by default access to the Media and Hotkeys such as Volume Up, Play/Pause, Desktop view, and so on.You can download Logi Options+ to get on-screen notifications when you swap from one to the other. Find the software here.
• If you prefer to have direct access to your F-keys simply press  Fn**  +  Esc**  on your keyboard to swap them.

Keyboard backlight behavior when charging****

• Your keyboard is equipped with a proximity sensor that detects your hands whenever you come back to type on your keyboard.The backlighting will stay on for five minutes after typing, so if you are in the dark, the keyboard won’t turn off while typing
• Once charged and the charging cable removed, the proximity detection will work again.
• Proximity detection will not work when the keyboard is charging — you have to press on a key of the keyboard to turn the backlight on. Turning the keyboard backlight off while charging will help with the charging time.

Keyboard backlighting changes by itself****

• Your keyboard is equipped with an ambient light sensor that adapts the keyboard backlight according to the brightness of your room.

  • If the room is dark, the keyboard will set the backlighting to a low level.
  • In a bright environment, it will adjust to a high level of backlighting to add more contrast to your environment.
  • When the room is too bright, over 200 lux, the backlighting will turn off as the contrast is no longer visible, and it won’t drain your battery unnecessarily.

When you leave your keyboard but keep it on, the keyboard detects when your hands approach and it will turn the backlight back on. The backlighting won’t turn back on if:

  * Your keyboard has no more battery, below 10%.
  * If the environment you’re in is too bright.
  * If you’ve turned it off manually or using Logitech Options software.

• There are three default levels that are automatically if you do not toggle the keys:

Keyboard backlight does not turn on****

Your keyboard backlight will automatically turn off under the following conditions:

• The keyboard is equipped with an ambient light sensor — it assesses the amount of light around you and adapts the backlight accordingly. If there is enough light, it turns the keyboard backlight off to prevent draining the battery.
• When your keyboard’s battery is low, it turns the backlight off to allow you to continue working without disruption.

Connect new device to a USB receiver****

Each USB receiver can host up to six devices.

1. Open Logitech Options.
2. Click Add Device, and then Add Unifying device.
3. Follow the on-screen instructions.
   NOTE: If you don’t have Logitech Options you can download it here.

You can connect your device with a Unifying receiver other than the one included with your product.
You can determine if your Logitech devices are Unifying by the logo in orange on the side of the USB receiver:

Backup device settings to the cloud in Logitech Options+****

INTRODUCTION** WHAT SETTINGS GET BACKED UP**  This feature on Logi Options+ allows you to backup the customization of your Options+ supported device automatically to the cloud after creating an account. If you are planning to use your device on a new computer or wish to go back to your old settings on the same computer, log into your Options+ account on that computer and fetch the settings you want from a backup to set up your device and get going.When you are logged into Logi Options+ with a verified account, your device settings are automatically backed up to the cloud by default. You can manage the settings and the backups from the Backups tab under More settings of your device (as shown):

• AUTOMATIC BACKUP OF SETTINGS**  — if the  Automatically create backups of settings for all devices**  checkbox is enabled, any settings you have or modify for all of your devices on that computer are backed up to the cloud automatically. The checkbox is enabled by default. You can disable it if you don’t want the settings of your devices to be backed up automatically.
• CREATE A BACKUP NOW****  — this button allows you to backup your current device settings now, if you need to fetch them later.
• RESTORE SETTINGS FROM BACKUP****  — this button lets you view and restore all the available backups you have for that device that are compatible with that computer, as shown above.

The settings for a device are backed up for every computer that you have your device connected to and have Logi Options+ that you are logged into. Every time you make some modifications to your device settings, they get backed up with that computer name. The backups can be differentiated based on the following:

• Name of the computer. (Ex. John’s Work Laptop)
• Make and/or model of the computer. (Ex. Dell Inc., Macbook Pro (13-inch) and so on)
• The time when the backup was made

The desired settings can then be selected and restored accordingly.

• Configuration of all the buttons of your mouse
• Configuration of all the keys of your keyboard
• Point & Scroll settings of your mouse
• Any application-specific settings of your device

• HOW IT WORKS****

• INTRODUCTION****

• HOW IT WORKS****

Keyboard/Mice – Buttons or keys do not work correctly****

Likely Cause(s):****

• Potential hardware issue
• Operating system /software settings
• USB port issue

Symptom(s):****

• Single-click results in double-click (mice and pointers)
• Repeating or strange characters when typing on the keyboard
• Button/key/control gets stuck or responds intermittently

Possible solutions:****

1. Clean the button/key with compressed air.
2. Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.
3. Unpair/repair or disconnect/reconnect hardware.
4. Upgrade firmware if available.
5. Windows only****  — try a different USB port. If it makes a difference, try updating the motherboard USB chipset driver.
6. Try on a different computer.  Windows only****  — if it works on a different computer, then the issue might be related to a USB chipset driver.

** *Pointing devices only:**

• If you’re not sure if the problem is a hardware or software issue, try switching the buttons in the settings (left click becomes right click and right click becomes left click). If the problem moves to the new button it is a software setting or application issue and hardware troubleshooting cannot resolve it. If the problem stays with the same button it is a hardware issue.
• If a single-click always double-clicks, check the settings (Windows mouse settings and/or in Logitech SetPoint/Options/G HUB/Control Center/Gaming Software) to verify if the button is set to  Single Click is Double Click****.

NOTE: If buttons or keys respond incorrectly in a particular program, verify if the problem is specific to the software by testing in other programs.

Delay when typing****

Likely Cause(s)****

• Potential hardware issue
• Interference issue
• USB port issue

Symptom(s)****

• Typed characters take a few seconds to appear on the screen

Possible solutions****

1. Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.
2. Move the keyboard closer to the USB receiver. If your receiver is in the back of your computer, it may help to relocate the receiver to a front port. In some cases the receiver signal gets blocked by the computer case, causing a delay.
3. Keep other electrical wireless devices away from the USB receiver to avoid interferences.
4. Unpair/repair or disconnect/reconnect hardware.
   • If you have a Unifying receiver, identified by this logo,  see Unpair a mouse or keyboard from the Unifying receiver.
   • If your receiver is non-Unifying, it cannot be unpaired. However, if you have a replacement receiver, you can use the Connection Utility software to perform the pairing.
5. Upgrade the firmware for your device if available.
6. Windows only****  — check if there are any Windows updates running in the background that may cause the delay.
7. Mac only****  — check if there are any background updates that may cause the delay.
8. Try on a different computer.

Unable to pair to Unifying receiver****

If you’re unable to pair your device to the Unifying receiver, please do the following:

STEP A:****

1. Make sure the device is found in Devices and Printers. If the device is not there, follow steps 2 and 3.
2. If connected to a USB HUB, USB Extender or to the PC case, try connecting to a port directly on the computer motherboard.
3. Try a different USB port; if a USB 3.0 port was used previously, try a USB 2.0 port instead.

STEP B:****

• Open Unifying Software and see if your device is listed there. If not, follow the steps to connect the device to a Unifying receiver.

USB receiver does not work or is not recognized****

If your device stops responding, confirm that the USB receiver is working properly.

The steps below will help to identify if the issue is related to the USB receiver:

1. Open  Device Manager****  and make sure your product is listed.
2. If the receiver is plugged into a USB hub or extender, try plugging it into a port directly on the computer
3. Windows only****  — try a different USB port. If it makes a difference, try updating the motherboard USB chipset driver.
4. If the receiver is Unifying, identified by this logo,  open Unifying Software and check if the device is found there.
5. If not, follow the steps to connect the device to a Unifying receiver.
6. Try using the receiver on a different computer.
7. If it’s still not working on the second computer, check Device Manager to see if the device is recognized.

If your product is still not recognized, the fault is most likely related to the USB receiver rather than the keyboard or mouse.

Flow network setup check for Mac****

If you are having difficulty establishing a connection between two computers for Flow, follow these steps:

1. Check both systems are connected to the internet:

   • On each computer, open a web browser and check the internet connection by navigating to a webpage.

2. Check that both computers are connected to the same network:

   • Open the Terminal: For Mac, open your  Applications**  folder, then open the  Utilities**  folder. Open the Terminal application.
   • In the Terminal, type:  Ifconfig****
   • Check and note the  IP address  and  Subnet mask. Make sure that both systems are in the same Subnet.

3. Ping the systems by IP address and make sure that ping works:

   • Open the Terminal and type  ping ****  [Where the <IP address is the IP address of the other computer noted in Step 2 above]

4. Check that the Firewall and Ports are correct: Ports used for Flow:****
   TCP| 59866
   ---|---
   UDP| 59867,59868

5. Open the Terminal and type the following cmd to show the ports in use:
   > sudo lsof +c15|grep IPv4****

6. This is the expected result when Flow is using the default ports:NOTE: Normally Flow uses the default ports but if those ports are already in use by another application Flow might use other ports.

7. Check that the Logitech Options Daemon is added automatically when Flow is enabled:

  * Go to  ** **System Preferences****  >  ** **Security & Privacy****
  * In  ** **Security & Privacy**** go to the  ** **Firewall****  tab. Make sure the Firewall is on, then click on  ** **Firewall Options****. (NOTE: You may have to click the lock in the bottom left corner to make changes which will prompt you to enter the account password.)

NOTE: On macOS, the firewall default settings automatically allow ports opened by signed apps through the firewall.  As Logi Options is signed it should be added automatically without prompting the user.

4. This is the expected result: The two “Automatically allow” options are checked by default. The “Logitech Options Daemon” in the list box is added automatically when Flow is enabled.
5. If Logitech Options Daemon is not there, try the following:
  * Uninstall Logitech Options
  * Reboot your Mac
  * Install Logitech Options again
6. Disable Antivirus and reinstall:
  * Try disabling your Antivirus program first, then reinstall Logitech Options.
  * Once Flow is working, re-enable your Antivirus program.
