I would copy the macro I posted to a general module in your workbook or
Personal.xls.
Make a copy of the macro and change ws.Protect to ws.UnProtect in the
second copy.
If you're not familiar with VBA and macros, see David McRitchie's site for
more on "getting started".
http://www.mvps.org/dmcritchie/excel/getstarted.htm
or Ron de De Bruin's site on where to store macros.

In the meantime..........
First...create a backup copy of your original workbook.
To create a General Module, hit ALT + F11 to open the Visual Basic Editor.
Hit CRTL + r to open Project Explorer.
Find your workbook/project and select it.
Right-click and Insert>Module. Paste the code in there. Save the
workbook and hit ALT + Q to return to your workbook.
Run or edit the macro by going to Tool>Macro>Macros.
You can also assign this macro to a button or a shortcut key combo.
