How To Fix “ALT Codes” Now Working in Windows 11 and Windows 10

Keyboard shortcuts and special characters have become an integral part of our digital communication. Among these, ALT codes hold a special place, allowing users to input a plethora of unique characters, symbols, accents, and emojis.

However, in Windows 11 and Windows 10, you may occasionally encounter issues where ALT codes stop working.

This comprehensive guide will delve into the causes of these problems, discuss various methods to fix them, and provide insights on how to use ALT codes for a wide array of characters.

ALT Codes

Understanding ALT Codes and Their Importance

ALT codes are keyboard shortcuts used to insert special characters and symbols that aren’t readily available on a standard keyboard.

They consist of holding down the ALT key and then typing a specific number on your keyboard’s numeric keypad.

These codes can represent a wide range of characters and symbols, including checkmarks, accents for French and Spanish languages, a variety of emojis, and much more.

Common Causes for ALT Codes Not Working in Windows 11 and Windows 10

Before diving into solutions, let’s understand some common reasons why ALT codes might stop working:

  • Incorrect Keyboard Layout: If you’re using a non-standard keyboard layout, ALT codes might not function as expected.
  • Numeric Keypad Issues: ALT codes typically work with the numeric keypad, not the number keys above the letters. If your keyboard doesn’t have a numeric keypad, or if the ‘Num Lock’ is off, ALT codes might not work.
  • System Settings: Certain system settings, such as Mouse Keys or Sticky Keys, might interfere with the functioning of ALT codes.

How to Fix ALT Codes Not Working

Now that we understand the possible causes, let’s explore how to rectify these issues.

1. Check Your Numeric Keypad

ALT codes usually require the numeric keypad for input. If your keyboard doesn’t have a numeric keypad or if ‘Num Lock’ is turned off, ALT codes won’t work. Ensure that ‘Num Lock’ is turned on when using ALT codes.

2. Change Keyboard Layout

If you’re using a non-standard keyboard layout, switching back to the standard US English layout can often fix issues with ALT codes. You can change this in the Windows settings under ‘Time & Language’ > ‘Language’ > ‘Preferred Languages’.

3. Turn Off Mouse Keys

Mouse Keys is a Windows feature that lets you control your mouse pointer with your numeric keypad. However, it can interfere with ALT codes. You can turn off Mouse Keys in Windows settings under ‘Ease of Access’ > ‘Mouse’.

4. Use the Character Map

If ALT codes still aren’t working, you can use the built-in Character Map tool in Windows to insert special characters. Just search for ‘Character Map’ in the Start Menu, and you’ll find a grid of special characters that you can copy and paste.

How to Use ALT Codes

Now that we’ve discussed how to fix common issues with ALT codes, let’s delve into how you can use them. Remember, for ALT codes to work, your numeric keypad must be active. If you’re working on a laptop without a numeric keypad, we’ll discuss an alternative way.

1. Standard ALT Codes

To use an ALT code, hold down the ALT key, then type the numeric code on the numeric keypad. For example, ALT + 251 will insert the checkmark symbol ( √ ).

2. ALT Codes Without a Numeric Keypad

If you’re using a laptop or keyboard without a numeric keypad, you can still use ALT codes by enabling the ‘Function Key’ (Fn). Press and hold the ‘Fn’ key, and then use the embedded numeric keypad in your laptop’s keyboard.

ALT Codes for Accents, Symbols, Emojis, and More

ALT codes can represent a variety of symbols, accents, and even emojis. For instance:

  • French Accents: ALT + 133 (à), ALT + 138 (è), ALT + 140 (î), ALT + 147 (ô), ALT + 151 (û)
  • Spanish Accents: ALT + 160 (á), ALT + 130 (é), ALT + 161 (í), ALT + 162 (ó), ALT + 163 (ú)
  • Check Mark Symbol: ALT + 251 ( √ )
  • Emojis: ALT + 1 (☺), ALT + 2 (☻), ALT + 3 (♥), and so on.

A comprehensive list of ALT codes can be found online, providing a wide array of symbols, letters, and special characters to enhance your digital communication.


ALT codes are a powerful tool for enriching your digital text, but occasionally they can run into issues, especially in Windows 10 and Windows 11.

By understanding the common causes of these problems and knowing how to resolve them, you can ensure that your ability to use ALT codes remains unhindered.

Remember, the magic of ALT codes lies in the expansive list of characters they can represent, so don’t hesitate to explore and utilize them to their full potential.
