Chromebook keyboard typing wrong symbols? Fix it

You press a key and get a different symbol than the one printed on it. This often happens when the Chromebook has switched to a different keyboard layout or input method. It does not necessarily mean the keyboard is broken.

Check whether the keys register, then compare what they type and select the layout that matches your keyboard. The Keyboard Test can help separate a key that is not registering from a layout that is producing unexpected characters.

Check the keys and the characters

1. Open the Keyboard Test and press a few of the keys that produce the wrong symbols. Check whether each press registers.
2. Open a text field where you can type without submitting anything. Try the same keys once by themselves and once with Shift.
3. Compare the characters you get with the symbols printed on the keys. If you use a keyboard with an AltGr key, test that key combination too.
4. Check the language or keyboard indicator near the clock in the Chromebook shelf. If it shows a layout you do not normally use, select the layout that matches your keyboard.

The Keyboard Test checks whether key presses reach the browser. It does not change your Chromebook's input method or settings. To check which characters a layout produces, use a text field as well.

What the result means

The keys register, but they type different symbols

The keyboard is sending key presses, so a layout or input-method mismatch is a likely cause. For example, a US layout and a UK layout put some punctuation symbols in different places. Choose the layout that matches the physical keyboard, not just the language you usually write in.

A key does not register in the test

If one key fails repeatedly while nearby keys work, its switch, connection, or keyboard circuitry may be the problem. Restart the Chromebook and test again. If the same key still fails, check whether it also fails when you sign in or use another text field.

Only combinations with Shift or AltGr are unexpected

That points more strongly to a layout difference or an input method with special character behavior. Some layouts use Alt with another key to produce a third symbol. An international input method may also treat a punctuation key as a dead key, meaning it waits for the next key to make an accented character.

The built-in keyboard works, but an external one does not

The external keyboard may use a different regional layout from the Chromebook's built-in keyboard. The keycaps show the layout it was made for, but ChromeOS applies the selected input method to what the keyboard sends. Check its key labels and select the matching layout.

How to fix the layout

1. Switch back to the intended input method. Press Ctrl + Space to cycle through available input methods. Test the affected symbols after each change. If you have only one input method enabled, this shortcut may not change anything.
2. Choose the matching keyboard layout in Settings. Open Settings › Device › Keyboard and inputs › Inputs and keyboards, then select the layout that matches the keyboard. On some ChromeOS versions, the setting is under Settings › Languages and inputs › Input methods. You can search Settings for input methods if the menu names differ.
3. Remove an input method you do not use. In the input methods list, remove extra layouts that you might select by accident. Keep any layout you regularly need for another language, and check the shelf indicator when symbols change unexpectedly.
4. Check the keyboard language indicator. Click the language or keyboard indicator near the clock and choose the right input method. If the indicator changes while you type, you may be switching layouts with the keyboard shortcut.
5. Restart and test again. Restart the Chromebook after changing the layout. Then test the problem keys in the Keyboard Test and in a text field. This helps confirm that the change fixed the actual symptom.

When the keyboard may be faulty

If the right layout is selected but one key still fails to register in the Keyboard Test, restart the Chromebook and test again. If possible, compare with an external keyboard or another account on the Chromebook. A key that repeatedly fails in different text fields may have a damaged switch or connection.

For a school-managed Chromebook, an administrator may control keyboard settings. Ask the school or organization to check the input methods before attempting a repair. If the built-in key remains unresponsive after the layout and software checks, contact the device's support provider or a repair shop.

Why the printed symbols may not match

The keyboard layout tells ChromeOS which character to produce for each physical key. A keyboard made for one region can have different punctuation positions from another region, even when both keyboards connect and type normally. In that case, the Chromebook is not misreading a broken key. The selected layout simply does not match the keycaps.

The keyboard test runs in your browser. Key presses are checked on your device.
