Macro protect sheet but leaving cell range able to be edited

[Kemidan2014]

I know the code to protect and unprotect my sheets or work book.

and i know you can set a range to be able to be editted. but does that reset every time you protect and unprotect and reprotect the sheet is it really as simple as i just need to go into "Allow Edit ranges" button in Review tab on the sheet I want and then leave the Protect and unprotect VBA code in my macro alone and it iwll always remember? Or do i have to add more code to my Sheet protection in my macro to allow editting?

Example I want to leave W2:AK50 to be able to be editted when i open the file or use any of the other macros i have to transfer data.
