How to Fix Arrow Keys Not Working in Microsoft Excel

If the arrow keys are not moving the active cell in Microsoft Excel, start with Scroll Lock. When Scroll Lock is on, the arrow keys scroll the worksheet instead of moving the selection. If the arrows move a text cursor inside a cell, Excel is probably in Edit mode instead. The steps below cover both cases and the less common causes.

Quickly identify what the arrow keys are doing

1. Turn off Scroll Lock

Press the Scroll Lock or ScrLk key once. On some laptop keyboards, you may need to hold Fn while pressing the key. Microsoft confirms that Scroll Lock changes the arrow keys from cell navigation to worksheet scrolling. You can also right-click Excel’s status bar and make sure Scroll Lock is enabled in the status-bar menu so its state is visible. See Microsoft’s Scroll Lock instructions for Excel.

2. Use the On-Screen Keyboard if there is no ScrLk key

Press Windows + Ctrl + O to open the Windows On-Screen Keyboard, then select ScrLk. Return to Excel and test the arrow keys again. This is especially useful on compact laptops and keyboards that omit a dedicated Scroll Lock key.

3. Exit Excel Edit mode

If an arrow key moves the insertion cursor within a cell or formula, Excel is in Edit mode. Press Enter to finish the edit, press Tab to finish and move right, or click another cell. Microsoft documents that arrow-key behavior changes while a cell is being edited; see Edit cell contents in Excel.

4. Test the keyboard outside Excel

Open Notepad or another simple text editor and test all four arrow keys. If they also fail there, the problem is not specific to Excel. Reconnect the keyboard, try another USB port or another keyboard if available, and check Settings > Accessibility > Keyboard. Sticky Keys is not required for normal Excel arrow navigation, and Filter Keys can alter how repeated or brief keystrokes are handled. Microsoft explains these controls in its Windows keyboard accessibility guide.

5. Start Excel in Safe Mode

1. Close Excel.
2. Press Windows + R.
3. Type excel /safe and select OK.
4. Open a workbook and test the arrow keys.

If the keys work in Safe Mode, an add-in, startup file, or customization is a likely cause. Microsoft uses Safe Mode as a standard isolation step for Excel problems in its Excel troubleshooting guidance.

6. Disable Excel add-ins and test again

In normal Excel, go to File > Options > Add-ins. At the bottom, choose COM Add-ins from the Manage list and select Go. Clear the enabled add-ins, restart Excel, and test the arrows. If the issue is gone, re-enable add-ins one at a time and restart Excel after each change until you find the conflict. Repeat with Excel Add-ins if necessary.

7. Update Microsoft 365 or Office

Open File > Account, then choose Update Options > Update Now. If Update Now is not available, updates may be managed by your organization. Microsoft’s current Office update instructions note that managed installations may require help from an administrator.

8. Repair Office if the problem still persists

On Windows 11, open Settings > Apps > Installed apps, find Microsoft 365 or Office, open its menu, and choose Modify. Start with Quick Repair. If that does not help, use Online Repair, which is more thorough and requires an internet connection. Microsoft notes that repairing an Office product repairs the suite, not only Excel; follow its Office repair instructions.

Two old fixes you can skip

You do not need to enable Sticky Keys to make Excel’s arrow keys work, and the Excel option Enable fill handle and cell drag-and-drop controls mouse-based filling and dragging rather than arrow-key navigation. If Scroll Lock is off, Excel is not in Edit mode, and the keyboard works in other apps, Safe Mode and add-in troubleshooting are the better next steps.
