Your side mouse buttons typically aren't working because they lack a default action assigned by your operating system, or they are not being recognized as individual, distinct buttons by your computer or the specific application you're using. Unlike the standard left and right-click buttons, which have universal functions built into the operating system, additional mouse buttons often require specific software or in-application configuration to function.
Core Reasons Your Side Buttons Aren't Working
The primary reasons for unresponsive side mouse buttons stem from how operating systems and software interpret these additional inputs:
- No Default Operating System Action: Operating systems like Windows or macOS only assign default actions to the primary mouse buttons (left-click and right-click). Any extra buttons, including those on the side, are typically unassigned by default, meaning they won't perform any action unless explicitly configured.
- Lack of Recognition or Assigned Function: It's common for side buttons to either not be recognized as unique, distinct buttons by the system itself, or even if recognized, no action has been linked to them. Without a specific command tied to their press, they remain inactive.
- Program-Specific Functionality: The functionality of your side buttons often depends on the program you are trying to use them in. They might work perfectly in one game or application but be completely unresponsive in another, simply because the second application doesn't have a default mapping for them, or you haven't customized its settings.
Understanding Mouse Button Behavior
To better illustrate why your side buttons may not be working, consider the different ways your computer handles standard versus custom mouse inputs:
| Feature | Left/Right Click (Mouse 1 & 2) | Side Buttons (Mouse 3+) |
|---|---|---|
| Default OS Behavior | Pre-assigned universal actions (e.g., select, context menu). | No default actions; typically unassigned by the OS. |
| OS Recognition | Always recognized as core input devices. | May require specific drivers or software for individual recognition. |
| Requires Extra Software | No, functions out of the box. | Often requires manufacturer's software for customization. |
| Common Use Cases | Fundamental interaction, navigation. | Back/forward in browsers, custom macros, shortcuts in games. |
Solutions to Get Your Side Buttons Working
To enable and customize your side mouse buttons, you'll generally need to install software or adjust settings. Here's how:
1. Install Manufacturer Software and Drivers
Many gaming mice or advanced productivity mice come with dedicated software from their manufacturers (e.g., Logitech G Hub, Razer Synapse, SteelSeries GG, Corsair iCUE). This software is crucial for:
- Button Recognition: Ensuring the operating system fully recognizes each side button as a distinct input.
- Custom Assignment: Allowing you to assign specific functions, macros, or keypresses to each side button.
- Profile Management: Saving different button configurations for various applications or games.
Steps:
- Visit your mouse manufacturer's official website.
- Locate the support or downloads section for your specific mouse model.
- Download and install the latest drivers and customization software.
- Open the software and navigate to the button assignment or customization settings to configure your side buttons.
2. Check In-Game or Application Settings
Many games and specific applications (like video editors or CAD software) have their own built-in keybinding or control settings.
Steps:
- Open the game or application where you want to use the side buttons.
- Go to the "Settings," "Controls," or "Keybindings" menu.
- Look for options to remap actions and try assigning them to your side mouse buttons.
3. Utilize Third-Party Remapping Software
If your mouse doesn't have manufacturer software, or you need more advanced remapping capabilities, third-party utilities can help. Programs like X-Mouse Button Control (for Windows) or Karabiner-Elements (for macOS) allow you to assign custom functions to all mouse buttons, even generic ones.

4. Update Mouse Firmware
Sometimes, a mouse's firmware (the internal software on the device) might be outdated or corrupted, causing functionality issues. Check your manufacturer's software for any available firmware updates and install them.
5. Basic Troubleshooting Steps
Before diving into complex solutions, try these simple checks:
- Restart Your Computer: A fresh boot can resolve temporary software glitches.
- Try a Different USB Port: A faulty USB port can prevent proper device recognition.
- Test on Another Computer: This helps determine if the issue is with the mouse itself or your computer's setup.
- Clean the Buttons: Dust or debris can sometimes lodge under buttons, preventing proper registration.
By understanding that side mouse buttons generally require explicit configuration rather than relying on default operating system functions, you can effectively troubleshoot and enable them for your specific needs.
