There are a few ways to unlock cells in Excel. One way is to select the cells you want to unlock and then go to the Format menu. Select Cells and then click on the Protection tab. Uncheck the Locked box and then click on OK.

Another way to unlock cells is to use the keyboard shortcut Ctrl+1. This will open the Format Cells dialog box. Click on the Protection tab and then uncheck the Locked box. Click on OK and the cells will be unlocked.

A third way to unlock cells is to use the Excel VBA code. This code can be used to unlock all the cells in a worksheet or a specific range of cells. To unlock all the cells in a worksheet, use the code below:

Sub UnlockCells()

For Each c In Range("A1:A65536")

c.Locked = False

Next c

End Sub

To unlock a specific range of cells, use the code below:

Sub UnlockRange()

Range("A1:A5").Locked = False

End Sub
