Two things you'll want to change - opening in read-write mode, and ensuring Quit() is called regardless of terminating errors.
To avoid opening the workbook in read-only mode, change the value of the 3rd parameter argument passed to Open():
$wb = $excel.Workbooks.Open($excelfile,$true,$false)
# ^
# This is the ReadOnly parameter
To ensure Quit() is always called, use a try/finally statement:
$excelfile="C:\Users\Administrator\Pictures\unprotect_org - Copy\unprotect - Copy (2).xlsx"
$excel = New-Object -ComObject Excel.Application
try {
$excel.Visible = $false
$excel.DisplayAlerts = $false
$wb = $excel.Workbooks.Open($excelfile,$true,123)
$wb.SaveAs($excelfile,[Type]::Missing,$password)
}
finally {
$excel.Quit()
}
If PowerShell reaches the first statement inside the try block, it guarantees that the finally block will execute before returning control from the block - even if the call to SaveAs() (or any other invocation) throws a terminating exception
